摘要
The distribution and accumulation of polycyclic aromatic hydrocarbons (PAH) in soil as well as PAH profiles have been investigated in areas with different anthropogenic pollution such as the city of Tallinn, the towns of Parnu and Kohtla-Jarve and some rural areas. PAH were identified in 147 soil samples (0-10 cm upper layer) collected in September 1996. The typical Sigma PAH level in Estonian rural soil is about 100 mu g/kg dry weight. PAH concentrations in Tallinn, Parnu and Kohtla-Jarve soil were quite high (the mean Sigma PAH concentrations were 2240, 7665 and 12390 mu g/kg dry weight, respectively). The dominant PAH in soil samples were pyrene, triphenylene and fluoranthene. 3-4 ring PAH and 5-6 ring PAH ratio altered from 5:1 to 1.7:1. (C) 1999 Elsevier Science Ltd. All rights reserved.
