Large gaps in knowledge of marine pollution levels and trends in Europe have been underlined in a European environment agency report. The study concludes that inputs of cadmium, mercury, lead, DDT, lindane and PCBs generally declined by half during the 1990s. Concentrations in marine organisms also fell. The agency stresses, however, that data limitations mean the assessment relates only to the north-east Atlantic. Nor is there enough data to assess other regulated hazardous substances. It recommends actions to fill these gaps. See report.
