Abstract
Six metals (cadmium, copper, nickel, lead, iron, and zinc) were determined by inductively coupled plasma–optical emission spectrometry in crawfish (tails and whole bodies) and soil in the vicinity of the crawfish, in a season of 4 months (February through May) in southwest Louisiana. Cadmium and lead were not found in the tail or whole body. Nickel was found in some samples of tail but mostly in the April and May samples. Copper, iron, and zinc were found in both tail and whole body of the crawfish. Limited soil sampling showed no cadmium, nickel, or copper in soil, but levels of iron, lead, and zinc were detected.
