W. Devries et al., CALCULATION AND MAPPING OF CRITICAL LOADS FOR HEAVY-METALS AND PERSISTENT ORGANIC POLLUTANTS FOR DUTCH FOREST SOILS, Journal of hazardous materials, 61(1-3), 1998, pp. 99-106
In order to enable application of the critical load approach in the in
ternational heavy metal and POP abatement policies, critical loads of
lead, cadmium, copper, zinc, lindane and benzo(a)pyrene have been calc
ulated for Dutch forest soils. The environmental risk of atmospheric d
eposition of these substances on Dutch forest soils has been described
in terms of the difference between the calculated present atmospheric
loads and critical loads. Results indicate that the calculated critic
al loads strongly depend on the type of environmental quality criteriu
m which serves as a basis for the calculation. More information on the
quality criteria to be used is thus essential to gain insight in the
risk of the loads of heavy metals and POPs on the terrestrial ecosyste
