European Critical Loads of Cadmium,Lead and Mercury and their Exceedances

摘要

Critical loads of cadmium,lead and mercury were computed by 18 countries of the LRTAP Convention.These national data were collated into a single database for the purpose of identifying sensitive areas in Europe.Computing exceedances,i.e.comparing the critical loads to atmospheric deposition,shows that cadmium was not a widespread risk in 2000,that the risk from lead deposition has decreased since 1990 but was still widespread in 2000,and that the risk from mercury remains high without much change from 1990 to 2000 in most of the countries.
