The monitoring is focused on risk assessment of LRTAP -type substances in terrestrial foodchains of the Boreal and subarctic environment. The concentration levels in precipitation, in the soil humus and in the indicator species (e.g. red woodants, common shrew) are studied annually in the seven areas locating in the Southern, Middle and Northern Finland. Possible gradients and changes in concentration levels between the Southern and Northern environments will be a part of the base data for risk assessment and pollution development in Finland.
