Impact on non target organisms of anti-marine wood-borer treatments. Evaluation of stress imposed by treatments on organisms from test sites ArchiMer

In European waters, significant economic damages to wooden structures are caused by bivalves molluscs and crustaceans. Treatments like copper-chrome-arsenic mixtures (CCA) were designed to prevent settlement of these wood borer species. However, limited and conflicting evidence regarding the toxicity to non-target organisms are available in the literature. This report aims to provide insights regarding the CCA leachates' toxicity to an important aquaculture species, the blue mussel Mytilus edulis for which much information on normal and stressed physiology is available for purposes of comparisons. The mussels are usually considered as a particularly suitable species for biological monitoring (Smaal and Widdows, 1994). To address the CCA leachate issue, two...

Experiments were canied out to assess the copper-chrome-arsenic (CCA) trealment effeets on the Blue mussel Mytilus edulis physiology. Experimental design included two complementary approaches: 1) scope for growth esrimates based upon the energy balance between respiration energy loss and energy gained from feeding processes. 2) a biological early waming system for valve behavior monitoring under CCA exposures. Various temperature range (seasonal effeet). physiological status (mature & immature mussels) as weil as CCA concentrations (from 0 to 48kg/m3) and rime exposure were tested. Significant monality rates for the experimental mussel populations were recorded in alI experimental modalities but the 2kg/m3 CCA treatment concentration. Overall results...
