What is PAH Sources in Karst Seepage Waters about?

This study examines PAH content in karst seepage waters and ecosystem compartments over snowmelt and dry periods. PAH profiles in seepage waters were consistently similar to wet deposits, changing between winter and summer. However, atmospheric wet deposits showed loss of high molecular weight PAHs, which accumulate in soils. A mass balance during a summer storm suggests dry deposits and canopy throughfall could account for PAHs in seepage waters. This demonstrates PAHs can transfer directly from atmosphere
