This study comprehensively investigated the occurrence, sources, and potential toxicity risks of 16 PAHs in main urban area surface soils Changchun, northeast China.The total (Σ PAHs) concentrations decreased significantly along commercial traffic district, industrial zone, residential park outskirt farmland, ranging from 46.6 to 8870.8 ng/g, with a mean value 1480.1ng/g 4-ring were always dominant constituents all land used soils.Based on ArcGIS mapping, higher are mainly concentrated...
Organochlorine pesticides (OCPs) were quantified in a sediment core from Songhua Lake, large artificial lake Northeast China, to investigate their historical deposition behaviors and reconstruct use history.The total OCPs concentrations ranged 17.74 411.86 ng/g.Dichlorodiphenyltrichloroethane (DDTs) hexachlorocyclohexanes (HCHs) recorded as the dominant components.Historically, contaminations input significant during 1950s with also certainly mid-1960s 1990s corresponding historically...
