『Abstract
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.
