BEYOND STATUS AND TRENDS OF COASTAL CHEMICAL CONTAMINATION APPRAISED BY BIOMONITORING : ACHIEVEMENTS AND CHALLENGES FACING THE FRENCH MUSSEL WATCH PROGRAM

The French mussel-watch program collected its first bivalve in 1979, and has been monitoring the status and trends of contaminants along the coastline ever since. Spatial and temporal resolutions are high, and have been optimized according to costs and environmental behavior of contaminants. Monitored contaminants show local, regional and temporal variations. The usefulness of this near real time monitoring program is increased by unforeseen environmental applications. Indeed, the mussel tissue samples have been archived into a collection of well characterized marine coastal environmental records which remains available for research purposes until sample exhaustion. In this presentation, we show examples of reconstruction of contamination histories that are solely accessible through reanalysis of this collection. Reconstructions range from organic contaminant fingerprinting to metal stable-isotopic geochemistry. Despite this biomonitoring’s inherent shortcomings, the time series prove invaluable to assess legislation for ecosystems protection. Paradoxically, unintended consequences of the implementation of EU-WFD jeopardize this record in terms of its very existence, quality and continuation.
