| Abstract: |
| In order to explore the concentration, spatial-temporal variation and its potential sources of organochlorine pollutants (OCs), polyurethane foam (PUF) passive air samplers were deployed in different functional areas in Ningbo from October 31, 2014 to October 30, 2015. The predominant congeners were DDTs, endosulfans, HCHs, atrazine, and chlorothalonil with mean concentration of 210, 160, 4500, 280 pg·m-3 and 87 pg·m-3 respectively. The highest concentration of OCs were observed in urban greening areas and tea plantation area, while the lowest were coastal area and flower plantation area. The concentration of OCs in different agricultural area had different spatial characteristics. Pollution characteristics indicated fresh input of DDTs and endosulfans. Additional, high values of o,p' -DDT and o,p'-DDT/p,p'-DDT in coastal area suggested the usage of dicofol. The correlation between the atmoshperic concentration of OCs and the temperature showed that the tea plantation and flower planting area was affected by atrazine, chlorothalonil and endosulfans. |
