摘要: Baseline concentrations of lead, cadmium, mercury and selenium are reported from different tissues in marine organisms Greenland. Overall, lead levels Greenland low, whereas high. Tissue differences not very distinct for the opposite is case cadmium mercury. Selenium shows an intermediate behaviour this respect.
