Trace elements in oyster farming areas in the Amazon
Analyses of contaminants in sediments, such as trace elements, are fundamental to characterize normality or alterations in aquatic environments. These are important data to evaluate areas used for aquaculture, particularly those where there is a closer interaction between sediments and organisms...

| description |
Analyses of contaminants in sediments, such as trace elements, are fundamental to characterize
normality or alterations in aquatic environments. These are important data to evaluate areas used for
aquaculture, particularly those where there is a closer interaction between sediments and organisms
cultured, as in oyster cultivation. The concentrations of trace elements (Al, Cd, Co, Cr, Cu, Fe, Ni, Mg)
were assessed in the sediments of six oyster farming areas in the Amazon estuary. Sediment sampling
was carried out in the months of November 2013 (dry season) and April 2014 (rainy season) and
central areas were prioritized. Levels of trace elements were quantified by induced plasma optical
emission spectrometry (ICP-MS). Possible effects on aquatic biota were evaluated by comparing
the levels of metals in the sediments with the reference values proposed in the TEL and PEL
protocols. The concentrations of trace elements in sediments in all evaluated areas were higher in
the rainy season, except for copper. Following the order of concentration, in most of the locations
Al> Fe> Mg> Cr> Ni> Co> Cu> Cd. Only Cd levels were higher than the TEL and PEL. |
