Toxic effects of polychlorinated biphenyl bio accumulation in sea urchins exposed to contaminated sediments
Abstract The uptake patterns and toxicity of poly chlorinated biphenyl (PCB) congeners in the white sea urchin, Lytechinus pictus , on exposure to contaminated sediments were investigated. First‐order modeling of uptake of the 10 most abundant PCB congeners or domains (containing more than one coelu...
