Abstract
- Cilj: U ovom istraživanju uzorci cvjetnoga meda korišteni su kao bio-pokazatelji onečišćenja okoliša pesticidima. Materijal i metode: Ukupno je prikupljeno 40 (4x10) uzoraka sa 4 različite prostorne lokacije (subregije), u ukupno 16 općina, od proizvođača meda u Varaždinskoj županiji, kao i 20 (2x10) uzoraka s dvije različite lokacije proizvođača u susjednoj županiji, registriranih kao "ekoloških proizvođači", a udaljenih od poljoprivrednih površina pod konvencionalnom proizvodnjom. Analize su provedene korištenjem vezanog sustava plinske kromatografije i spektrometrije masa (GCMS) i tekućinskom kromatografijom visoke djelotvornosti (HPLC). Rezultati: Identificirano je i kvantificirano 78 aktivnih sastojaka pesticide, koji su dio od ukupno cca 400 pesticida koji se analiziraju u voću i povrću, a za koje je laboratorij raspolagao analitičkom opremom koja i dijelom određuje i vrstu i broj pesticida koje se detektiraju. Rezultati analiza ukazali su na mogući uzročno posljedični odnos između konvencionalnih poljoprivrednih aktivnosti u Varaždinskoj županiji s identificiranim i kvantificiranim aktivnim sastojcima pesticida. Iz rezultata dobivenih na udjelima identificiranih i kvantificiranih ostataka pesticida, s obzirom na dopustivost, vidljivo je da je udio dopuštenih pesticida u uzorcima cvjetnoga meda iznosio 55,2%, dok je udio ilegalnih pesticida iznosio 44,8%. Analizirajući broj otkrivenih insekticida i fungicida, ukupno na sve 4 lokacije utvrđeno je da cvjetni med sadrži 13 različitih vrsta insekticida i 3 vrste fungicida. Zaključak: Rezultati i statistička analiza podataka pokazuju da je cvjetni med dobar bio-indikator onečišćenja okoliša pesticidima, te stoga ova studija može poslužiti kao osnova za znanstvenike i stručnjake koji se bave istraživanjem štetnih učinaka pesticida na okoliš i ljudsko zdravlje.<br />Aim: In this research samples of floral honey were used as bio-indicators of environmental pollution by pesticides. Material and methods: A total of 40 (4x10) samples from bee farms were collected at 4 different locations (sub-regions) including 16 municipalities in the Varaždin County, as well as 20 (2x10) samples from two locations – bee-farms registered as "ecological producers" in the neighborhood County, both located far away from conventional agricultural production. Analyses were carried out using the gas chromatography joint system with mass spectrometry (GCMS) and high-performance liquid chromatography (HPLC). Results: Identification and quantification of 78 pesticide active ingredients were performed which are part of a total of approximately 400 pesticides that are usually analyzed in fruits and vegetables whereby the laboratory had available analytical equipment that also determined the number of detected pesticides. Due to identified and quantified active ingredients of pesticides, the results of analyses might indicate a possible cause-effect relationship with conventional agricultural activities in the Varaždin County. It was evident from the obtained results on the shares of identified and quantified pesticide residues, and with respect to admissibility, that the share of permitted pesticides in the samples of floral honey accounted for 55.2%, while the share of illegal pesticides accounted for 44.8%. Analyzing the number of detected insecticides and fungicides, on a total of all 4 locations (sub-regions), it was found that floral honey contained 13 different types of insecticides and 3 types of fungicides. Conclusion: The results and statistical data analysis showed that floral honey is a good bio-indicator of environmental pollution by pesticides, therefore this study can serve as a basis for scientists and experts engaged in the research of harmful effects of pesticides on the environment and human health.
