Long-term decline of atmospheric and marine pollution by polycyclic aromatic hydrocarbons (PAHS) in Germany.
Concentrations of benzo[a]pyrene and benzo[e]pyrene in the atmosphere as markers for the class of PAHs decreased by about 70% within one decade in clean air as well as in industrially polluted areas of Germany when measured with passive samplers (spruce sprouts, poplar and beech leaves). The same trend has been found for East-Germany during 1991-1995. Mussels (Mytilus edulis) were found to accumulate PAHs from the aquatic environment and exhibited a seasonal periodicity of the PAH concentration. After an initial decline from 1985 to 1990, the PAH concentration remained constant until 1995 in the North Sea area investigated.
