PCP in the freshwater and marine environment of the European Union

This study collates monitoring data principally from 1991 to 1996, relating levels of pentachlorophenol PCP. in the freshwater and marine environments of the European Union EU. Member States of Belgium, France, Germany, the Netherlands and the UK. In general, PCP levels in the open freshwater and marine environments displayed a downward trend in these countries, and where increased PCP concentrations were observed, these were tentatively linked to specific point discharges. The monitoring data were compared against the relevant predicted no-effect concentration PNEC. for PCP in a particular environmental medium. On this basis, the study suggests that PCP does not pose a risk to the coastal, estuarine, marine waters or marine sediments of the above countries, and that any risks posed by PCP to the freshwater environment can largely be attributed to sediments contaminated with PCP from historic usage, or due to the continued use of small quantities of sodium pentachlorophenyl laurate in northern France. Further analysis of the data was not possible owing to the lack of systematic reporting by Member States, the lack of information on usage quantities and patterns, and inconsistent environmental surveillance and reporting of environmental data. This is particularly relevant for south-west France, Portugal and north-east Spain, the region which accounts for almost 90% of the EU’s consumption of NaPCP. These issues need to be addressed at a pan-European level to better inform the selection of risk management measures and to improve the effectiveness of such measures.
