• Description: The presented study is concerned with the impact of municipal STPs on smaller rivers in the Czech Republic. Surface waters have been sampled by two types (pesticide and pharmaceutical versions) of Polar Organic Integrative Samplers (POCIS) upstream and downstream of 7 municipal sewage treatment plants situated on upper parts of streams in the Czech Republic. The extracts from passive samplers were tested by a battery of in vitro bioassays to determine (i) overall non-specific cytotoxicity, (ii) endocrine-disruptive, ED, potential (estrogenicity, androgenicity) and (iii) dioxin-like toxicity of the river waters downstream and upstream of STPs. The results document that all monitored STPs negatively affected water quality. The in vitro detection systems revealed significant presence of estrogenic compounds in the samples and showed increase of their concentrations in all downstream samples compared to the upstream ones.
