To exam ine the residues and distributions of hexachlorocyclohexanes (HCHs), dichlorodiphenyltrichloroethane (DDT), and other organochlorine pesticides (OCPs ) in the Weihe River basin of northwest China, a gas chromatography-mass spectrometer (GC-MS) was employed to analyze the samples collected from surface water, suspended solids, and sediments. Results showed that total concentrations of HCHs,...
Our study assessed the non-carcinogenic risks of heavy metals in the sources of drinking water treatment plants located along Huaihe River in Jiangsu Province, China. High-resolution inductively coupled plasma-mass spectrometry and inductively coupled plasma-atomic emission spectroscopy were used to determine the levels of eight metals in the water from 30 treatment plants. Non-carcinogenic risks...
