Determination of two progestin metabolites (17a-hydroxypregnanolone and pregnanediol) and different classes of steroids (androgens, estrogens, clorticosteroids, progestins) in rivers and wastewaters by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)
A highly sensitive and robust method was developed for routine analysis of two progestin metabolites, 17α-hydroxypregnanolone (17OH-Δ5P) and pregnanediol (PD), and 31 other natural and synthetic steroids and related ...
Regulation of zebrafish (Danio rerio) locomotor behavior and circadian rhythm network by environmental steroid hormones
Environmental exposure of fish to steroid hormones through wastewater and agricultural runoff may pose a health risk. Thus far, ecotoxicological studies have largely been focused on the disruption of the sex hormone system, ...
Occurrence and ecotoxicological effects of free, conjugated, and halogenated steroids including 17a-hydroxypregnanolone and pregnanediol in Swiss watewater and surface water
Apart from estrogens, the occurrence and ecotoxicity of steroids in aquatic environments is poorly known. Here, we analyzed 33 steroids, including estrogens, androgens, progestins, and glucocorticoids, in hospital wastewaters, ...
