Arsenic uptake and depuration by red crayfish, Procambarus clarkii, exposed to various concentrations of monosodium methanearsonate (MSMA) herbicide
- Southern Univ., Baton Rouge, LA (USA)
Like many other heavy metals, arsenic is known to accumulate in the tissues of aquatic organisms including crayfish. One of the earliest reports on red crayfish, Procambarus clarkii, reported the bioaccumulation factor (BF) ratios for radioactive sodium methanearsonate to range from 80-480. Other heavy metals, i.e., Cr, Cd, Pb and Hg have also been reported to accumulate experimentally in P. clarkii tissues. This study was conducted to evaluate in the laboratory the bio-accumulative potential of As by the American red crayfish, Procambarus clarkii, which is abundant in Louisiana; and also to assess the level of arsenic present in the tissues of fieldcollected individuals. Total revenues from the sales of this crayfish exceeds $143 million annually.
