The concentrations of chemicals in sewage sludge from wastewater treatment plants (WWTPs) may relate to their levels of use and environmental pollution in the region. In this work, sludge samples were collected from 31 WWTPs in 26 cities in China and analyzed for polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs). The concentrations of ∑PBDE (sum of congeners 17, 28, 47, 66,...
A simple electroanalytical method for determination of inorganic sulfur species in ground waters was developed. The procedure involved determination of trace sulfide, thiosulfate and sulfite in different media with oscillopolarographic technique and indirect determination of sulfate with adsorptive complex wave of lead (II)-tetrakis (4-trimethylammonium phenyl) porphyrin. This method was applied...
