Abstract
Disposal of e-waste is a global issue and has caused serious pollution in recycling areas. Most of these areas had once developed intensive agriculture and might incur organochlorine pesticides (OCPs) pollution. However, this used to be neglected. Here we discuss the joint effects via analyzing OCPs and heavy metals in a notorious e-waste recycling area. The OCPs showed higher (p = 0.005) pollution levels in soils from agricultural zone than in core e-waste recycling zone, which is opposite for heavy metals (p = 0.02). The OCPs and heavy metals showed the highest concentrations in the open burning site locating in the boundary between the e-waste and agricultural zones. Composition profiles further indicated that the land use changes from agriculture to e-waste industry might accelerate the release of buried OCPs. Worse still, the OCPs and heavy metals might pose carcinogenic and non-carcinogenic risks to local residents, respectively.
