The objective of this work was to evaluate the bioaccumulation mercury in 13 species fish with different eating habits, captured Três Marias Reservoir, São Francisco Basin, from March 2012 April 2013. results obtained showed that carnivorous habit presented highest average concentrations muscle, especially Serrasalmus brandtii (pirambeba) and Pygocentrus piraya (piranha), 0.4147 ± 0.2744 μg g-1...

Few cities in the world biomonitor changes human levels of persistent organic pollutants (POPs) through periodic health surveys representative general population. To analyze serum concentrations POPs Barcelona from 2006 to 2016, and socio-demographic correlates 62 2016. Participants Health Surveys 2016 (N = 231 240, respectively) were interviewed face-to-face, gave blood, underwent a physical e...

Environments contaminated with metals can induce accumulation of trace in soft tissues marine fauna resulting negative effects. The oral brooding sea star Anasterias minuta is one the most conspicuous macro-invertebrate top-predator species Atlantic Patagonian rocky shores which could accumulate elements and be used as biomonitor coastal metal pollution. aim this study was to quantify concentra...

background in the golestan cohort study that was launched to investigate the causes of esophageal cancer, a complete biospecimen bank was established for storage of collected blood, urine, hair, and nail samples. the objective of this study was to evaluate the feasibility of nail samples as a biomarker of selected trace elements status. methods thirty toenail samples were selected randomly from...

Abstract Invasive species usually grow in human-disturbed habitats including urban areas where they face numerous pollutants, metals that attract special attention due to their non-degradability and high accumulation potential. In this study we evaluated the contents of potentially toxic (Cd, Cr, Cu, Fe, Mn, Ni, Pb Zn) invasive Solidago gigantea. The strategy adopted by S. gigantea response exc...

Summary Lead (Pb) and cadmium (Cd) are heavy metals considered possible contaminants of water, soil air (especially when occurring as a consequence human activities in agriculture or industry), can be found the liver kidneys animals, thus serving indicators pollution. Vojvodina is northern province Republic Serbia which boasts very intensive agricultural production, especially crop production. ...

The heavy metal Cd accumulates in trophic chains, constituting a toxic element for photosynthesizing organisms, including the algal photobionts of lichen. Thus, as lichens respond differently to toxicity, we hypothesized that species Parmotrema tinctorum and Usnea barbata, commonly sampled Cerrado ecoregion, could be sensitive and, therefore, used biomonitor dispersion this metal. We also aimed...
