TL;DR: It is shown that these dyes contributed to the mutagenic activity found in the Cristais River environmental samples analyzed and are indirectly affecting the quality of the related drinking water.

TL;DR: It is demonstrated that chlorinated derivatives of NP, OP, and BPS, even if artificially produced during wastewater processing, were less estrogenic than their parent chemicals, known as endocrine disruptors.

TL;DR: Chlorinated derivatives of bisphenol A were detected in the final effluents of eight paper manufacturing plants in Shizuoka, Japan, where thermal paper and/or other printed paper is used as the raw material.

TL;DR: The estrogenic activity potentially stemming from 17beta-estradiol (E2) in drinking water, using ESI-LC-MS was used to identify the products of its aqueous chlorination under the following conditions, appears to be induced mainly by 2,4-dichloro-E2 and 2,7alpha-methyloctahydroinden-5-one.

TL;DR: The estrogenic activities of bisphenol A and its chlorinated derivatives were evaluated by an agonist assay using the yeast two-hybrid system with and without a metabolic activation test using rat liver S9.
