Trace elements in commercial shrimps caught near port activities in SW Atlantic Ocean and human health risk assessment on consumption

Abstract

This study presents the concentration of trace elements in commercial shrimps caught in coastal fishing areas near large port activities of southeast Brazil (∼20°S–22°S), SW Atlantic Ocean. The seabob shrimp Xiphopenaeus kroyeri and the Argentine stiletto shrimp Artemesia longinaris were sampled in 2017, and the trace elements were determined in the muscle (edible portion). For all sampling sites (Vitória, Anchieta and Farol de São Thomé), the highest concentrations were Al > Fe > Zn > As > Cu, followed by Pb, V, Ni, Cr, Cd and Sn in lower concentrations. Only Zn and Cu were related to the intensity of port activities. According to the maximum permissible limits for trace elements established by the Brazilian Government for fishery products, the estimated daily intake and the maximum safe daily consumption rate, the edible portion of the two shrimp species does not present risk for human health.
