Objective: to investigate the screening of metallic hypersensitivity performed by health professionals and students during clinical-surgical practice. Method: an exploratory-descriptive study conducted with 228 health professionals and students, through a semi-structured electronic questionnaire, applied during April and May 2021, analyzed through descriptive statistics and the frequency of words. Results: 11.0% of participants conducted research on metallic hypersensitivity. 67.1% stated that they could very likely include this theme during screening in their care. Lack of knowledge about metal allergy and multifactorial causes during clinical-surgical practice were cited as barriers to the implementation of metallic hypersensitivity screening. Conclusion: there is little evidence of metallic hypersensitivity screening in patients during the clinical-surgical practice of health professionals and students. [ABSTRACT FROM AUTHOR]

The process of identifying a contaminated area involves a preliminary assessment consisting of chemical analysis and comparison with guideline values. In Brazil, these values are included in the CONAMA Resolution no. 420/2009, based on chemical analysis and phytotoxicity. The objective of this research was to evaluate the ecotoxicity of copper in two natural soils in the state of Rio de Janeiro, a Haplic Planosol (sandy) and a Red-Yellow Argisol (medium texture), to verify if the values established by the legislation offer protection to the soil fauna. Lethality and reproduction tests were performed with Eisenia andrei worms and Folsomia candida springtails. Results indicated copper values in Planosol as LC50 435 mg kg 1 and EC50 29 mg kg 1 for E. Andrei and LC10 137 mg kg 1 and EC50 117 mg kg 1 for F. candida. In Argisol, these results were LC50 690 mg kg 1 and EC50 61 mg kg 1 for E. andrei, and LC10 42 mg kg 1 and EC50 138 mg kg 1 for F. candida. Values reported are lower than the research value (200 mg kg-1) established by the CONAMA resolution 420/09, indicating that concentrations lower than the limit values may affect these organisms, depending on the type of soil. Worms were more sensitive than springtails to copper contamination, and sandy soil was more susceptible to ecotoxicity due to copper contamination, probably due to the greater bioavailability of the metal. Results of such ecotoxicity tests should be considered in the development of soil guideline values. [ABSTRACT FROM AUTHOR]

Martianthus leucocephalus is found in the semi-arid Northeast of Brazil and has high pharmacological potential due to the production of volatile compounds. This study aimed to evaluate the Cd (15, 30, 45 and 60μmol L-1), Cu (30, 60, 90 and 120μmol L-1) and Zn (150, 300, 450 and 600μmol L-1) levels on the growth of this species and its volatile compounds production. Apical cuttings were placed in plastic trays containing 6.0L nutrient solution, and after rooting, they were submitted to Cd, Cu and Zn treatments for 15 days. All the metals evaluated reduced the succulence and growth of all parts of M. leucocephalus. This effect was accompanied by the increase of Cd, Cu and Zn concentrations in all plant tissues. Volatile compounds content produced by M. leucocephalus was increased only by Zn (86%). [ABSTRACT FROM AUTHOR]

In recent years, the process of urbanization has been growing in Iguatu, important city of the semi-arid region of Brazil. This process has influenced the quality of aquatic environments due to effluent discharge and the emission of pollutants. Iguatu has modern and efficient sewage treatment system, but only 15% of the population benefits. This paper aimed at the determination of 9 metals and 12 physical-chemical parameters to characterize of Bastiana Lake-CE and to evaluate the influence of effluent discharge. The results of the analysis of toxic metals showed presence of Zinc (Zn) and manganese (Mn) at levels above of maximum limits established by Brazilian legislation. Exposure to Mn can affect the IQ (Intellectual quotient). Water samples showed high concentration of organic matter (BOD), nitrogen, phosphorus, soluble substances hexane and presence of floating materials. The level of nutrients (N and P) classified the lake as eutrophic and hypereutrophic and may cause risk to human health. Results suggest that actions must be taken by government agencies to prevent the complete degradation of Lake Bastiana (Ceará, Brazil). [ABSTRACT FROM AUTHOR]
