摘要

After decades of regulating the emission of anthropogenic substances into the environment, a retrospective analysis of their effects is informative, as it allows determining the actual costs and benefits related to the regulations. As a first example we have considered the case of gasoline lead in Europe. With the help of a regional climate model, NCEP re-analyses, spatially disaggregated lead emissions from road traffic and other sources, and various local data, an attempt was made to reconstruct the airborne pathway and deposition of gasoline lead in Europe since 1958. It turns out that this approach is successful in describing the time-variable, spatially disaggregated deposition of gasoline lead. Additional data from analyses of concentrations in, for instance, leaves, mussels and human blood, allows an assessment about the impact of the phasing-out of lead on the quality of the environment. Demonstrating the success of the lead policy, the concentrations in leaves and human blood has steadily declined since the early 1980s, whereas the concentration in mussels along the North Sea coast is unaffected.
