Occurrence and distribution of organochlorine pesticides (OCPs) in surface sediments of the Bohai Sea, China

Occurrence and distribution of organochlorine pesticides and polycyclic aromatic hydrocarbons in surface sediments from Qinghai Lake, northeast Qinghai–Tibet plateau, China

“…These low abundances suggest no recent use of dicofol within the study area. These results are different from those reported for the Bohai Sea (Hu et al, 2009), the Pearl River Delta , Taihu Lake, China (Zhao et al, 2009), Cinca River, Spain (de la Cal et al, 2008, and Sai Gon-Dong Nai River basin, Vietnam (Minh et al, 2007). In these areas the DDTs patterns indicated the input of from recent usage.…”

Spatial distribution and seasonal variation of four current-use pesticides (CUPs) in air and surface water of the Bohai Sea, China

“…The samples with elevated concentrations were associated with air masses passing through the eastern coastal area of China (see Fig. 4SA6), where agriculturalization and industrialization activities have rapidly developed, discharging large amounts of pesticides to the Bohai Sea (Hu et al, 2009;Pan et al, 2016;Wang et al, 2008). This indicates high levels of pollution from terrestrial sources.…”

Characteristics of residual organochlorine pesticides in soils under different land-use types on a coastal plain of the Yellow River Delta

“…The c-HCH as dominated HCH isomer in the upstream of Yellow River with a low concentration in the YRD soil implied the sediment input from Yellow River might be the main source of the OCPs in the delta compared to the anthropogenic activity Gao et al 2008). Hu et al (2009) reported agricultural dicofol application, chemical plants effluent and the usage of DDT for antifouling paints together lead to the elevated DDT concentrations in sediments at coastal area of Bohai Sea. Salinity was positively correlated with o,p 0 -DDT (Fig.…”
