Abstract

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.

摘要

作为多环芳烃类别的标志物，大气中苯并[a]芘和苯并[e]芘的浓度，在德国的清洁空气以及工业污染地区，使用被动采样器（云杉嫩枝、杨树和山毛榉树叶）进行测量时，在十年内下降了约70%。东德在1991 - 1995年期间也发现了同样的趋势。贻贝（紫贻贝）被发现会从水生环境中积累多环芳烃，并且其体内多环芳烃浓度呈现季节性周期变化。在所调查的北海地区，多环芳烃浓度在1985年至1990年最初下降之后，一直保持恒定直到1995年。
