| polychlorinated biphenyls and chlorinated pesticides in king mackerel caught off the coast of pernambuco, northeastern brazil: occurrence, contaminant profile, biological parameters and human intake. | persistent organic pollutants such as pcbs and ddts are ubiquitous worldwide. their lipophilic nature facilitates accumulation in fish tissues. this study investigated 182 pcb congeners and 14 organochlorine pesticides (ddts, hchs, chlordanes, heptachlor and mirex) in muscle and liver of king mackerel (scomberomorus cavalla) caught off the northeastern coast of brazil. concentration of pcbs, ddts and chlordanes in muscle averaged 31.5, 4.70 and 0.15ngg(-1) dry weight (dw), respectively. mean lev ... | 2016 | 27392580 |
