Steroid hormones in the aquatic environment
نویسندگان
چکیده
Steroid hormones are extremely important natural in all vertebrates. They control a wide range of physiological processes, including osmoregulation, sexual maturity, reproduction and stress responses. In addition, many synthetic steroid widespread general use, both as human veterinary pharmaceuticals. Recent advances environmental analytical chemistry have enabled concentrations rivers to be determined. Many different hormones, synthetic, transformation products, been identified quantified, demonstrating that they aquatic contaminants. Laboratory ecotoxicology experiments, mainly conducted with fish, but also amphibians, shown some can adversely affect when present the water at low concentrations: even sub-ng/L. research has demonstrated mixtures inhibit each individual hormone is concentration below which it would not invoke measurable effect on its own. Limited field studies supported conclusions laboratory may pollutants significant concern. Further required identify main sources entering environment, better describe complex now known ubiquitously present, determine impacts environmentally-realistic vertebrates, especially fish. Only once completed robust risk assessment concluded.

Dairy wastewater, aquaculture, and spawning fish as sources of steroid hormones in the aquatic environment.
A suite of androgens, estrogens, and progestins were measured in samples from dairy farms, aquaculture facilities, and surface waters with actively spawning fish using gas chromatography-tandem mass spectrometry (GC/MS/ MS) to assess the potential importance of these sources of steroid hormones to surface waters. In a dairywaste lagoon, the endogenous estrogens 17beta-estradiol and estrone and ...

متن کاملThe Steroid Hormones in Pregnancy
THE marked changes in hormone production in pregnancy are associated with changes in metabolism and function. Much of the work which has been done and is being continued in the Clinical Research Unit of this department is concerned with the changes in body composition in normal and abnormal pregnancy and the puerperium and in the uterine activity in la;bour. The earlier endocrine work had been ...
