A laboratory controlled study of uptake of copper, lead, and zinc in crawfish (Procambrus clarkii) by inductively coupled plasma optical emission spectrometry

摘要

In a laboratory controlled study, the uptake of various concentrations of parts per million (up to a maximum of 100 ppm) of copper, lead, and zinc in crawfish was studied. All three metals were absorbed by the crawfish with (in general) an increase in metal concentration showing an increase in metal absorption levels. Copper and zinc reached an optimum at 32 ppm, and 52 ppm added, respectively, where as lead continued accumulation with increasing lead concentration. Higher concentrations of lead were absorbed compared to copper and zinc.
