Abstract
This report deals with the histopathological/ultrastructural changes in various tissues of grass shrimp (Palaemonetes pugio) exposed to hexavalent chromium, pentachlorophenol (PCP) and two dithiocarbamate formulations: Aquatreat DNM-30 (15% sodium dimethyl dithiocarbamate plus 15% disodium ethylene bis-dithiocarbamate) and Busan-85 (50% potassium dimethyl dithiocarbamate). The pathological alterations induced by dithiocarbamates and PCP were most severe and first evident in the gills. Of the biocides tested, the dithiocarbamates caused the most extensive branchial damage--the so-called black gill syndrome, involving early melanization and eventual lamellar truncation.
