THE FRESHWATER MUSSELS ARE A GOOD BIOINDICATOR FOR MONITORING THE WATER POLLUTION BY HEAVY METAL (THE SAINT– VICTOR–SUR–LOIRE LAKE, FRANCE) (original) (raw)
The study has focused freshwater mussels to determine the risk of water pollution. We have shown that freshwater mussels are a good bioindicator for monitoring over time this type of water pollution due to their ability to filter water from the river. The entire food chain (freshwater mussels, mollusc, shrimp, fish, birds and humans) is affected by the pollution. The Saint Etienne (France) has a large industrial and mining history. The end of these activities has given way to industrial wasteland and mine dumps. Leaching by rain industrial and mining waste may generate a very large urban pollution. Rivers (Ondaine and Loire) and lakes (Saint–Victor–sur–Loire) downstream of this zone are highly polluted by heavy metals.
