INVESTIGATION OF DRY DEPOSITION FLUX OF POLYCYCLIC AROMATIC HYDROCARBONSn FROM TRAFFIC SOURCES USING A SURROGATE SNOW SURFACE SAMPLER

摘要

Atmospheric dry deposition of polycyclic aromatic hydrocarbons (PAHs) from traffic sources was investigated for the first time using a surrogate snow surface sampler at different distances (10 m, 100 m, and 400 m) from a highway with a heavy traffic load near the city center of Erzurum. The snow sampling was carried out twice. In the first sampling, fresh snow was taken immediately after heavy snow and placed in aluminum trays. The snow layer in the trays was used to obtain a dry surrogate surfa
