Abstract

Marine environments are continuously being threatened by a large number of pollutantsincluding heavy METALS and organophosphorous pesticides from anthropogenic sources. Thesecompounds can cause a serious environmental problem. The present study aimed: (1) to measuresensitivity of ACETYLCHOLINESTERASE (AChE) activity to in vivo exposure to the organophosphorouschlorpyriphos-ethyl (CPF) and to the heavy METALS cadmium (Cd) and copper (Cu) and (2) to use thehistopathological lesions as tissue biomarkers for biomonitoring of different contaminations. Theresults clearly showed that the AChE activity in different tissues (digestive gland, muscle and eyes)of Carcinus maenas was relatively sensitive to the concentrations of CPF and tended to have differentpatterns in response to Cd, Cu and Cu+Cd mixture exposure. The transfer of treated crabs to the cleansea water allowed to recover totally or partially the lost activity depending on selected tissues andcontaminant exposure (metals or organophosphorous compounds). HISTOPATHOLOGICAL BIOMARKERS inC. maenas exposed to different contaminants showed the presence of different lesions which alteredthe digestive gland after 7 days of contamination.
