| Zusammenfassung |
| Organochlorine pesticides (OCPs) are a sub-group of persistent organic pollutants (POPs),
which have raised the concerns from researchers all around the world for several decades. But
very little research has been conducted on POPs in the arid zone of Northwest China. More
than 100 soil and sediment samples were collected from Kaidu-Peacock River of Xinjiang,
Northwest of China, to investigate the organochlorine pesticides (OCPs) in this region
analysed by the gas chromatograph equipped with a mass selective detector (GC-MSD). Our
pre-study in 2006 (Chen et al. 2011) in the same region, showed that OCPs except o,p’-DDT
were detected in sediments from the Peacock River. Similar results were found in the whole
river catchment in this investigation. DDTs, HCHs, chlordanes and endosulfans were
the dominant OCPs residual in the soil and sediments. This study confirmed that
POPs, such as OCPs in this region were contributed to by both local emissions
and long-term atmospheric transport and may pose risks to human health and the
ecosystem.
