Review of atrazine sampling by polar organic chemical integrative samplers and Chemcatcher.

abstract：:The estrogenic activity of the effluent from three municipal wastewater treatment plants (WWTPs) in Nanjing, China, was investigated. The water samples were enriched by solid-phase extraction and then eluted with different polar solvents, which gave 11 fractionated extracts. Chemical analysis and a vitellogenin (Vtg) ...
