Development and implementation of an analytical procedure for the quantification of natural and synthetic steroid hormones in whole surface waters.

Glucocorticoids in Freshwaters: Degradation by Solar Light and Environmental Toxicity of the Photoproducts

The photodegradation process of seven glucocorticoids was studied in tap and river water at a concentration close to the environmental ones and revealed no significant differences in toxicity between the parent compounds and their photoproducts, but the two organisms showed different responses.

Estrogenic, androgenic, and glucocorticoid activities and major causative compounds in river waters from three Asian countries.

Estrogen, androgen, and glucocorticoid receptors (ER, AR, and GR) agonist activities in river water samples from Chennai and Bangalore (India), Jakarta (Indonesia), and Hanoi (Vietnam) were evaluated

Thyroid Hormones in Sediment and Water: Method Validation and Detection in Taihu Lake of China

Study of the occurrence and fate of thyroid hormones in aquatic environments requires a highly sensitive method that is capable of detecting such compounds at sub-ng/L concentrations. By using

Determination and Occurrence of Mineralocorticoids in Taihu Lake of China

We developed a sensitive method for monitoring six natural (aldosterone) and synthetic mineralocorticoids (canrenone, spironolactone, 7β-spironolactone, 7α-thio spironolactone, and 7α-thiomethyl

Evaluation and Application of a Novel Diffusive Gradients in Thin-Films Technique for In Situ Monitoring of Glucocorticoids in Natural Waters.

The potential environmental risks of glucocorticoids (GCs) have attracted attention in the past few decades. In this study, a novel diffusive gradients in thin-films (DGT) device and analytical

Occurrence of Pharmaceuticals and Endocrine Disrupting Compounds in Brazilian Water and the Risks They May Represent to Human Health

The risks of pharmaceuticals and endocrine disrupting compounds (P&EDC) to the environment and human health are a current topic of interest. Hundreds of P&EDC may reach the environment, hence, there



Occurrence of Glucocorticoids, Mineralocorticoids, and Progestogens in Various Treated Wastewater, Rivers, and Streams.

This study revealed the ubiquitous presence of topically applied GC monoesters betamethasone propionate, betamETHasone valerate, and 6α-methylprednisolone Propionate in WWTP effluents and surface water.

Occurrence of natural and synthetic glucocorticoids in sewage treatment plants and receiving river waters.

The ratio between the combined concentrations of two natural glucocorticoids (cortisol and cortisone) and the concentration of one synthetic glucocORTicoid, prednisolone, was found to be a potential index to reflect the wastewater discharging.

Endocrine disrupting compounds affecting corticosteroid signaling pathways in Czech and Swiss waters: potential impact on fish.

The results suggest that these chemicals may impact wild fish, and an increase in fish glucocorticoid plasma levels comparable to 0.9-83 ng/mL cortisol after exposure to the analyzed river waters was estimated.

Balancing the Budget: Accounting for Glucocorticoid Bioactivity and Fate during Water Treatment.

Data from this study represent the first known publication where a complete activity balance has been determined for GR agonists in an aquatic environment.

Determination and source apportionment of five classes of steroid hormones in urban rivers.

A principal component analyses with multiple linear regression based on the profiles of all target compounds was applied to identify the source apportionment and to predict the contribution from different sources and it was found that 62.7% of the mean summed hormones were contributed by freshly discharged untreated sewage.

Determination of natural and synthetic glucocorticoids in effluent of sewage treatment plants using ultrahigh performance liquid chromatography-tandem mass spectrometry

A sensitive and comprehensive analytical method for glucocorticoids (GCs) in water samples was developed and applied to effluent of sewage treatment plants (STPs) and cortisol was detected in more than half of analyzed effluent samples at concentrations in the range of ND-1.36 ng/L, indicating continuous discharge of natural GC via STP effluent.

Behaviors of glucocorticoids, androgens and progestogens in a municipal sewage treatment plant: comparison to estrogens.

Glucocorticoids, androgens, and progestogens were mainly removed by degradation as with estrogens, while different behaviors were observed in the aerated grit chamber, anaerobic tank, anoxic tank, and aerobic tank units.

LC-MS/MS determination of potential endocrine disruptors of cortico signalling in rivers and wastewaters

The results show that not all compounds were sufficiently eliminated by the wastewater treatment, resulting in the presence of several steroids and nonsteroids in the final effluent, some of them at high concentrations up to 200 ng/L.
