The main aim of this study is to identify physiological characteristics, including Chl a, b, total Chl "a+b" and carotenoids, in potato genotypes under the influence of lead (Pb+2) and cadmium (Cd+2) heavy metals. Two potato genotypes from the Netherlands, Riviera and Agria, were used in the study. Potato tubers were transferred to 2 kg compost pots and placed in a controlled environment with a 12 photoperiod, a day/night temperature of 25/19°C and a relative humidity of 75%. Since Pb+2 and Cd+2 poisoning was greater than in the control and different fractions of heavy metal residues in the substrate were transferred to plant organs, the amounts of these two metals in each treatment (outside the control) were measured. Plant pigments were extracted from fresh leaves in amounts ranging from 60 to 100 mg and these were then extracted into samples containing 80/20% (v/v) acetone/water with 0.5% w/v MgCO3 at room temperature for a full day. Photosynthetic pigments of each sample were extracted three times. The absorbances obtained at 663 nm, 644 nm and 452.5 nm for the maximum absorption of Chl a, Chl b and carotenoids, respectively, were used to measure the amount of chlorophyll and carotenoids. Differences between Pb+2 and Cd+2 and physiological markers were examined with the Duncan Multiple Range test. Information on Pb+2 and Cd+2 content in applications revealed wide variability. When potato genotype seedlings were exposed to varying levels of Pb+2 and Cd+2, the amount of chlorophyll and carotenoids in their leaves was lower than the control group. The results showed that there were significant and statistically significant changes in carotenoid and chlorophyll concentration at the LSD p = 0.01 level. Similar to Pb+2 and Cd+2 inhibiting plant growth, it had a negative effect on photosynthesis as well as chlorophyll and carotenoid contents. Moreover, these effects became more pronounced when the concentrations of two stress factors (Pb+2 and Cd+2) increased. [ABSTRACT FROM AUTHOR]

This study was conducted to determine the changes in the heavy metal and microelement contents of bean (Phaseolus vulgaris L.) plants with increasing doses of boron and sewage sludge applications. The experiment, which was set up according to the completely randomized design (CRD) in the climate chamber, was carried out with three replications. In the study where Mina, a standard dwarf bean variety, was used, four different boron doses (B0:0 mg/kg, B10:10 mg/kg, B20:20 mg/kg, B40: 40 mg/kg) and four doses of sewage sludge (SS0: %0, SS5: %5, SS10: %10, SS20: %20) were used as trial factors. In the study, sewage sludge treatments were found to be more effective in increasing the content of microelements in beans compared to control, such as aluminum, copper, manganese, zinc, iron, chromium, lead, nickel, arsenic, cadmium, and cobalt. At the same time, it was observed to cause a decrease in the content of boron. The highest microelement and heavy metal contents were measured at 5% and 10% sewage sludge doses. On the other hand, it was determined that boron applications increased the aluminum, copper, boron, zinc, cobalt, manganese, and nickel contents of bean plants compared to control plants, and decreased the iron, arsenic, cadmium, and lead contents. The study showed that the negative effects of increased metal contents as a result of sewage sludge applications can be tolerated with boron applications. It seems that it may be possible to reduce heavy metal pollution in plants with such boron treatments. [ABSTRACT FROM AUTHOR]

In this study, it was aimed to identify mushrooms gathered from two different regions and localities of Türkiye and to determine their heavy metal and nutrient contents. Four of the mushrooms (Coprinus comatus (O.F. Müll.) Pers, Cantharellus cibarius Fr., Pleurotus ostreatus (Jacq.) P. Kumm. and Lactarius glyciosmus (Fr.) Fr.) from nearby settlements, while the others (Hydnum repandum L., Pleurotus eryngii (DC.) Quél and Lactarius delicious (L.) Gray)) were collected from rural areas. All species have known and consume by local peoples. All identified species were given along with their trophic status, habitats, locations, Turkish names and edibility. Concentrations of elements were determined based on dry weight. The analysis of samples indicated that different result obtained from mushrooms. As (nd, 1.5-17.43), Ba (1.48-10.81), Cd (nd, 1.4-43.46), Co (nd, 12.0-42.79), Cr (nd, 5.0-14.92), Cu (12.95-143.45), K (nd, 30085-52680), Mg (nd, 5056-5955.9), Mn (52.45-187.25), Mo (nd, 1.22-57.53), Ni (43.46-565), Pb (318.9-1483.5), Sb (nd, 0.14-4.12), Si (nd, 3.18-87.83), Ti (20.32-302.2), V (67.66-102.3), Zn (1026.8-2422.0), Ca (411.5 -2077), Na (752.5-2105.5) and Fe (470.5-1093.5) were determined and the elements studied were given in mg/kg. As a result, it was determined that C. comatus, H. repandum, C. cibarius and P. eryngii had the lowest content of heavy metals and P. ostreus had the highest value in terms of calcium and magnesium contents. Therefore, it has been determined that these mushroom species may have important beneficial effects to human health. It is thought that it can be used as a source in future studies.

Objective: Multiple sclerosis (MS) etiology studies show that the disease is multifactorial. While genetic features are more prominent at the beginning of the disease, the existence of environmental triggers that may cause the progression of the disease is still a subject of research. Materials and. Methods: We evaluated 101 MS patients sharing the same geographical area. We performed heavy metal analysis in the blood and hair tissues of these patients. Of these patients, 67 were in the relapsing remitting MS (RRMS) group and 34 were in the progressive MS (PMS) group. Results: Samples were analyzed using the X Series 2 model (ICP MS) instrument. In hair samples, aluminum (Al) was found to be 8.98 µg/g in the PMS group and 3.01 µg/g in the RRMS group (P < 0.001). Unlike Al element, magnesium (Mg), calcium (Ca), cobalt (Co), zinc (Zn) and strontium (St) elements were observed to be higher in the RRMS group. RRMS for median Ca: 931 µg/g, PMS: 400 µg/g (P < 0.001); RRMS for Mg: 118 µg/g, PMS: 50 µg/g (P < 0.001); For Co RRMS: 0.0150 µg/g, PMS: 0.0075 µg/g (P = 0.008); RRMS for Zn: 138 µg/g, PMS: 101 µg/g (P = 0.008); For St RRMS: 4.76 µg/g, PMS: 3.70 µg/g (P = 0.008). With these results, we thought that Al excess or Mg, Ca, Co, and Zn deficiencies might be associated with MS progression. The mercury (Hg) blood level was slightly low in PMS. This finding was not correlated with hair samples (P = 0.047). The relationship between blood Hg level and RRMS should be evaluated separately. Conclusion: We could not find any study comparing PMS forms and RRMS subtypes in terms of heavy metals. In particular, it is necessary to focus on the Al element. [ABSTRACT FROM AUTHOR]

Contamination of drinking water with heavy metals is a serious threat to the global environment and public health. Currently, approximately 20 countries have been reported for arsenic levels present in drinking water that are higher than the EPA guidelines. Arsenic is highly toxic, widely dispersed and found in the earth's crust. It can be found in inorganic as well as organic compounds in water. Arsenic is released into the environment in a variety of ways, including industrial effluents, pesticides, wood preservative chemicals, combustion of petroleum and coal, and mining operations. Currently, Arsenic is determined using a wide variety of methods that include inductively coupled plasma mass spectrometry (ICPMS), highperformance liquid chromatography (HPLC) with ICPMS and graphite furnace atomic absorption spectrometry (GFAAS). Nevertheless, these methods are slow, expensive and require skilled people to operate. Alternatively, electrochemical sensors have been potentially recognized as a powerful analytical method for the detection of heavy metals at very low concentrations. It also allows on-site and continuous monitoring of heavy metals. A nanocomposite consisting of gold nanoparticles and conducting polymers (polydiallyldimethylammonium chloride (PDDA) and polystyrene sulfonate (PSS)) functionalized graphene was used in this study to detect arsenic, which causes major environmental and health concerns.

The aim of the research is to determine the macro (Ca, Mg, P and K), micro (Fe, Mn, Cu, Zn and Be) element and heavy metal (Al, Cr, Ni, Se and Cd) contents of some Astragalus taxa collected from nature. Nine Astragalus taxa (Astragalus gummifer, A. compactus, A. lineatus var. longidens, A. aureus, A. onobrychis, A. declinatus, A. lineatus var. lineatus, A. oocephalus subsp. stachyophorus, A. inereus) collected from the natural areas of Bingöl province were used as the plant material of the research. Astragalus taxa were collected from the central villages of Bingöl province in June 2018, during the flowering period of the plants. Macro, micro element and heavy metal contents of the collected and dried plant samples were determined with the help of NIRS (Near Infrared Spectroscopy) and ICP-MS (Inductively Coupled Plasma - Mass Spectometry) devices. As a result of the analysis, the average Ca content of Astragalus taxa was determined as % 1.63, Mg content % 0.36, P content % 0.27, K content % 1.49, Fe content 2436 mg kg-1, Mn content 153.7 mg kg-1, Cu content 84.5 mg kg-1, Zn content 14.08 mg kg-1, Be content 0.10 mg kg-1, Al content 2535 mg kg-1, Cr content 7.67 mg kg-1, Ni content 9.99 mg kg-1 and Se content 2.19 mg kg-1. In general, the highest Ca, Mg, Fe, Mn, Al, Cr and Ni contents were determined in A. declinatus, the highest P and K contents were determined in A. oocephalus subsp. stachyophorus, the highest Cu content was determined in A. cinearus, the highest Zn content was determined in A. lineatus var. longidens, the highest content Be was determined in A. gummifer and the highest Se content was determined in A. compactus. Cd content could not be detected in any Astragalus taxa. As a result of the study, it was concluded that Astragalus taxa, which are abundant in the natural flora of our country, can be used as a source of roughage in animal nutrition and can meet the macro and micro element needs of animals.

This study was carried out to determine the effects of boron and sewage sludge applications on the changes in micro element and heavy metal contents of the cowpea (Vigna unguiculata L.) plant. The experiment was carried out in the climatic chamber, in complete randomized plots, according to the factorial design with 3 replications. In the study where the Karagöz cowpea variety was used, four doses of boron (0 mg/kg, 50 mg/kg, 100 mg/kg, and 200 mg/kg boron) and four doses of sewage sludge (0%, 2.5%, 5%, and 10%) were applied as factors. As a result of the study, micro element contents of cowpea have both increased and decreased with sewage sludge applications, while heavy metal contents except aluminum have increased. The highest values were reached with 5% and 10% sewage sludge applications. Micro element contents generally increased with boron applications. With increasing boron applications, heavy metal contents such as Al, Cd, Co, Cr and Pb increased, while As and Ni contents decreased. It was observed that boron applications tolerated the negativities caused by the sewage sludge in the boron x sewage sludge interaction. Therefore, it can be said that the variable heavy metal contents caused by sewage sludge applications in cowpea plant can be balanced with boron applications. [ABSTRACT FROM AUTHOR]

In this research, heavy metal contents (Al, As, Pb and Cd) of 6 honey samples obtained from Marmara and Aegean regions of Turkiye (chaste berry, chestnut, jerusalem torn and sunflower kind of honeys) and 4 honey samples obtained from Bulgaria (lavender, acacia and sunflower kind of honeys) with micro and macro element contents including Ba, Cr, Co, Ni, Fe, Cu, Zn, Mn, Mg, P, B, Na, K, Sr, S and Ca were analyzed by ICP-OES (Inductively Coupled Optical Emission Spectrometer). It was found that the heavy metal contents (Al, As, Cd and Pb) in the investigated honey samples were below the toxic limit values specified by the World Health Organisation and the Turkish Food Codex. In general, the mineral contents of honey samples vary according to the regions where they were taken. Among the honey samples taken from different regions; the contents of Pb, Al, As, Cr, Cu, Ba, Sr, Zn, B, Ca, K, Na, P and S changed at 1% significance level, while Mn, Ni and Fe contents differ at 5% level of significance. It was determined that as the apiary locations from which honey samples were taken approached the urban areas, the Pb content increased statistically by 1%, while the As and Co content increased at the 5% level of significance.

In this study, it was aimed to determine heavy metal levels in muscle tissues of Atlantic bonito samples caught in the Eastern Black Sea Region and to determine their potential to pose a risk to human health. The concentrations of Fe, Zn, Cu, Pb, Mn, and Al have been measured in the edible muscle of Atlantic bonito (Sarda sarda Bloch, 1793) from the Trabzon and Rize coasts of the southern Black Sea from September 2020 to December 2020. Cd, Cr, Co, and Ni were not detected in the edible part of S. sarda in both coastal areas. These concentrations are lower than the maximum permissible values in European and Turkish regulations. The average weekly intake of heavy metals per body weight value not exceeded the Provisional Tolerable Weekly Intake (PTWI) established. Therefore, it may be concluded that these ten metals should not pose any health threat to the consumers resulting from the consumption of S. sarda. [ABSTRACT FROM AUTHOR]

Well waters were collected from 10 different points in rural areas of Bursa city. The aver age heavy metal doses in samples were found as (µg/L); Cu (183.40) > Fe (86.29) > Al (55.75) > Mn (20.2) > Cr (7.33) > Cd (5) > Ni (2.54) > As (2.23) > Se (1.99) > Pb (1.55) > Hg (1) > Sb (0.70) > B (0.0002). Since the WQI values of all samples are < 50, the water qualities were defined as "perfect" according to WHO (2011). Since the HPI values are < 100, heavy metal levels do not cause negative effects in terms of health. Since the HEI values are < 10, the results show that there is no significant pollution at the sources. The MCL values of all waters are below 0.01 mg/L according to EPA (2018) thus, they do not contain carcinogenic risks for humans and animals. [ABSTRACT FROM AUTHOR]

Heavy metals are widely known through natural resources, natural resources such as soil, dust in the atmosphere, snow and rain. Soil contaminants, especially heavy metals, can be absorbed by plants and enter the food cycle. Heavy metal contamination causes environmental concerns, such as entering the food chain and contaminating food, which can be harmful to human health. Consumption of food contaminated with heavy metals can cause several disorders including genetic toxicity, carcinogenicity, mutagenicity, teratogenicity, neurotoxicity, endocrine disorders, immune problems and impaired psychosocial function. Bees also absorb heavy metals through the consumption of contaminated water, pollen, and nectar, inhalation of particles during flight, and adhesion of particles to their hairy body as they move on plant and soil surfaces while searching for food. For this review study, keywords such as heavy metals and honey were used. The databases searched in those articles were Google Scholar, SID, Scopus, PubMed, Science Direct, and ISI. The searched articles were reviewed. Given that honey is a valuable and widely consumed food in the diet of most people in different nations, so the study of the quality of honey in the consumer market in order to maintain the health of consumers seems necessary.

Ülkemizde gelişmekte olan illerde nüfus artışına bağlı olarak araç sayısında ve trafikte yoğunluklar her geçen gün artmaktadır. Bu durum sosyo-ekonomik açıdan gelişme olarak değerlendirilse de çevreye (toprak-su-hava) olumsuz ekolojik etkileri olmaktadır. Otoyollar, şehirlerde yapılan önemli ve bir o kadar da gerekli mühendislik yapılarındandırlar. Özellikle şehirleri birbirine bağlayarak sosyo-ekonomik ve diğer alanlarda etkili bir konuma sahiptirler. Günümüzde artan otoyol taşımacılığı, hızlı şehirleşme ve artan araç sayısı trafikten kaynaklı ağır metal kirliliğini önemli bir konu haline getirmiştir. Toprakların ağır metaller ile yüksek oranda kirlenmeleri otoyollara yakınlıklarından kaynaklanmaktadır. Bu nedenlerle toprağa ulaşan ağır metallerin topraktan uzaklaştırılmasının zor olması nedeniyle toprak kirliliği önemli bir çevre sorunu olarak karşımıza çıkmaktadır. Bu çalışmada otoyol kenarlarında yer alan toprakların kirlilik durumu üzerine yapılan çalışmalar, kirleticilerin kaynakları ve dağılımı incelenmiştir.

The research was carried out in Bingöl for the determination of some elements and heavy metals in the extracted honey obtained after 2019 honey harvest. The levels of some elements and heavy metals were determined by ICP-MS (Inductively Coupled Plasma-Mass Spectrometer) in 11 extracted honey samples obtained from honey production areas. As, Cd, Cs, Hg, Li, Pb and Se were not found in honey samples. Other elements and heavy metals were found to have the following ranges: Al 14.10±12.68 ppb, Ca 12.79±42.40 ppb, Cr 2.51±0.58 ppb, Cu 0.98±0.38 ppb, Fe 28.84±12,92 ppb, K 3920.12±1806.12 ppb, Mg 128.66± 33.08 ppb, Mn 3.94±2.61 ppb, Na 140.62±61.21 ppb, Ni 2.02±0.65 ppb and Zn 9.71±6.74 ppb. When the results of the study were compared with some international limits for honey consumption. It was concluded that the honey in which the study tested would not pose any danger to human health from consumption. It is also comforting to find that no heavy metals have been detected in these honey samples. [ABSTRACT FROM AUTHOR]

In this study, the mineral content and heavy metal pollution levels of cow's milk and dairy products produced in Erzurum province and some districts were determined and how much these levels are affected from soil and plant structure are introduced. Ca, Na, K, Mg, Cu, Fe, Zn, Pb, Ni and Mn concentrations of samples taken from 335 cow milks, 82 milk products, 26 soils and 26 pasture-meadow plants are determined by using Inductive Couple Plasma Optic Emission Spectroscopy (ICPOES). In the examined cow milk samples, 1258.48±350.76 mg/kg of Ca, 415.51±167.17 mg/kg of Na, 1768.58±461.64 mg/kg of K, 107.33±31.19 mg/kg of Mg, 0.079±0.103 mg/kg of Cu, 0.64±3.45 mg/kg of Fe, 1.406±0.751 mg/kg of Zn, 0.031±0.048 mg/kg of Pb, 0.034±0.273 mg/kg of Ni and 0.022±0.11 mg/kg of Mn were determined. When compared with national and international values, it was found that there is no advanced pollution in heavy milk produced in Erzurum and its region. It was determined that there is no heavy pollution with any heavy metal in the soil of the region. It was determined that the milk samples showed different concentrations of Ca, Na, K, Cu and Pb (P<0.01) in the statistical evaluation according to periods (summer and winter).

In recent years, the use of statistical applications to assess the quality of aquatic ecosystems has increased. Principal Component Analysis (PCA) is a powerful multivariate statistical technique commonly used to assess environmental contamination. Ergene River Basin is the most important aquatic habitat of Thrace Region and is located in the north-western part of the Marmara Region of Turkey. The basin is intensively exposed to agricultural, domestic and industrial pollution. The aim of this study was to evaluate the macro and micro element accumulations (Li, Be, B, Na, Mg, Al, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Sb, Ba, Tl, Pb) in water of the lotic (lakes) and lentic (reservoirs) components of the Ergene River Basin by using Pearson Correlation Index (PCI) and Principal Component Analysis (PCA). For this purpose, water samples were collected in the spring season of 2018 from a total of 36 stations selected on the basin and some micro and macro element accumulations were determined. According to the results of PCI, significant relationships were found between the investigated macro and microelements in p<0.05 and p<0.01 significance levels. According to the PCA results, four factors explained 87% of the total variance in terms of total percentage variances after rotation [ABSTRACT FROM AUTHOR]

In this study, the transport and factors affecting the transport of Zn2+, Cd2+, Mo6+, Pb2+, Cu2+ and Fe3+ ions using a newly designed liquid membrane system were investigated. In the study, a new method, different from other liquid membrane techniques available in the literature, has been applied. This method is similar to the bulk liquid membrane system, as it differs slightly by passing the organic phase containing the ligand carrier from the donor and acceptor phase into droplets. It is called as "Multi Dropped Liquid Membrane System" (MDLM). The advantages of this technique include simple structure, lack of moving parts, light and portable, flexible operation, high membrane capacity and high separation factor. With this new method, it is aimed to reduce the working time, the risk of contamination, the amount of reagents used and the amount of waste produced. The system has been applied for transport of Zn2+, Cd2+, Mo6+, Pb2+, Cu2+ and Fe3+ ions from aqueous solutions and successful results have been obtained. Optimum transport conditions (donor and acceptor phase concentrations and pH, organic phase concentration, temperature, flow rate) were determined with suitable donor, carrier and acceptor solutions for each metal ion. The kinetic parameters and activation energy () were calculated for the interface reactions assuming two consecutive, irreversible first-order reactions, were calculated with interphase mass transfer laws. The results suggest that the MDLM system that used in the current experimental studies can be a great alternative and economical process in order to remove the heavy metal ions caused by heavy metal industries.

Autism spectrum disorder is a neuro-developmental disorder characterized by social interaction and communication, and restricted and repetitive behaviors. Autism is seen in nearly one of 68 children. The incidence is reported to increase, and the increase is suggested to arise from increased information, awareness and alterations in diagnostic criteria. However, environmental factors and their relationships to several unknown genetic factors are also considered to contribute to the increase. The assessment of whether environmental factors lead to risks for autism spectrum disorder in perinatal period, especially when children are exposed to these factors in a neurodevelopmentally important and fragile stage, is so important. It is reported that in pregnancy, there is an association between autism spectrum disorder, and exposure to such drugs as valporic acid, terbutaline and Selective Seratonin Reuptake Inhibitors. Exposure to heavy metals and pesticides increases the risk of autism spectrum disorder. Intense smoking, and alcohol consumption and drugsdisrupt neurodevelopmental process, Also, gestational diabetes may elavate the risk of autism spectrum disorder due to autoimmunal disorders, infections and inflammatory pocesse of prolonged fever. Migration, seasons and air pollution exposed in pregnancy are also reported to affect autism spectrum disorder risk. The awareness level between environmental factors and autism spectrum disorder should be increased among prospective mothers, and these mothers should be trained as to the risk factors. Because prospective mothers avoid these factors, or the elimination of these factors should be beneficial for reducing autism spectrum disorder risk, analyzing related studies and enlightening risk factors are especially important. Here, we aimed at revising recent studies related to prenatal factors from a holistic perspective. [ABSTRACT FROM AUTHOR]

In this study, it was aimed to investigate seasonal changes in levels of Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu), Zinc (Zn), Cadmium (Cd) and Lead (Pb) in liver, gill and muscle tissues of Chondrostoma regium from Batman Dam. Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze heavy metal concentration levels in the fish. The metal concentrations in the same tissues of samples taken from Batman Dam were slightly variable. Among the metals that were studied, concentration of Fe in the tissues of the fish was the highest. The metal concentrations in the liver and gill of Chondrostoma regium were higher than those in the muscle. The average heavy metal concentration in the muscle of Chondrostoma regium was higher in the autumn and winter. The amounts of metal in muscle tissues of the fish were found lower than the acceptable values in fish tissues. [ABSTRACT FROM AUTHOR]

Carrying between February 2012 and February 2013 as seasonal, the present study aims to determine heavy metal loads of five different creeks pass through Giresun city center and disembogue to Black Sea. Heavy metal analyses were performed from selected stations by ICP-MS instrument. Without seasonal and station differences, metal levels were found as follow; Cd: 0.129-5.113, Mn: 0.009-2.937, Fe: 0.007-1.985, Cu: 0.002-1.344, Zn: 0.002-1.901, Ni: 0.003-0.149, Pb: 0.009-21.22, Cr: 0.002-0.177, Co: 0.001-0.087 mg/L in water. Cd: 0.118-166.3, Pb: 5.62-398.9, Mn: 111.7-988.2, Fe: 2919-117973, Cu: 18.60-963.9, Zn: 11.09-2471, Ni: 11.29-813.1, Cr: 10.76-860.5, Co: 8.59-757.1 mg/kg in sediment. There were statistically significant differences between seasons in sea water. Statistically differences were found on Aksu, Güre, and Batlama stations. In sediment, statically differences in Cu, Zn, Ni, Co levels were found in winter season. The same elements were also statistically different on Güre station.

For the majority of the world population medicinal plants represent the primary source of the health care. Therefore determining the content of heavy metals, accumulated in medicinal plants, is of high importance. Thus, the purpose of this research was to evaluate the content of heavy metals and two metalloids in selected medicinal plants (Matricaria chamomilla L., Melissa officinalis L., Mentha piperita L. and Foeniculum vulgare Mill.), that are traditionally used in alternative medicine. The plant materials were collected in a highly industrialized town (Pančevo). Plant analyses were done according to ICP methodology. The obtained results show that the contents of the potentially toxic elements in the investigated medicinal plant species were below the recommended limits and those medicinal plants from the studied growing site are suitable for preparation of teas and medicinal extracts.

In the developing provinces of our country, the traffic jam and the number of vehicles gradually increased over day, which is related to the population growth. This situation could be identified as the socioeconomic development. However, it led to negative effects on soil-waterair. Highways are important and necessary engineering structures in the cities, which connect different cities and have an important effect on the socio-economic development and other areas. Today, because of increasing highway transport, the rapid urbanization and higher number of vehicles, heavy metal pollution of traffic become an important issue. For that reason, in these places soil pollution level is an important environmental problem, as it is difficult to remove heavy metals from the soil. Soils are close to the highways, leading to higher level of pollution due to heavy metals. This study examines previous researches on the pollution of lands, sources and distribution of pollutants which are located close to the highways. [ABSTRACT FROM AUTHOR]

Mercury (Hg), cadmium (Cd), lead (Pb), copper (Cu) and zinc (Zn) levels in European sea bass Dicentrarchus labrax (Linnaeus, 1758) and gilthead sea bream Sparus aurata Linnaeus, 1758 that are commercially sold on the Sinop fish markets were appraised. Selected heavy metals were assayed in edible tissues of the sampled fish, using an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The results are expressed in mg (kg wet wt.)-1. In both fish species, Cu was detected in higher concentrations, followed by Cu. The means of metal concentrations in D. labrax were 0.03±0.008 mg (kg wet wt.)-1 for Hg; 0.009±0.001 mg (kg wet wt.)-1 for Cd; 0.06±0.02 mg (kg wet wt.)-1 for Pb; 0.42±0.09 mg (kg wet wt.)-1 for Cu and 9.2±3.1 mg (kg wet wt.)-1 for Zn. Whereas the means of metal concentrations in S. aurata were 0.02±0.006 mg (kg wet wt.)-1 for Hg; 0.01±0.009 mg (kg wet wt.)-1 for Cd; 0.04±0.011 mg (kg wet wt.)-1 for Pb; 0.69±0.11 mg (kg wet wt.)-1 for Cu and 8.5±2.3 mg (kg wet wt.)-1 for Zn. None of the metals in European sea bass and gilthead sea bream were not above the permissible values. [ABSTRACT FROM AUTHOR]
