Development of a Bioassay to Measure Xenoestrogens in Environmental Water Samples. Xenoestrogens in water can cause feminization of fish, amphibians and other wildlife, interfere with reproduction and increase cancer. This research aims to develop a new test to measure xenoestrogens in water, based on a measure of the estrogen-activated genes that are switched on when cells are exposed to estrogens. If the research is successful, it will produce the best test in the world for measuring the effe ....Development of a Bioassay to Measure Xenoestrogens in Environmental Water Samples. Xenoestrogens in water can cause feminization of fish, amphibians and other wildlife, interfere with reproduction and increase cancer. This research aims to develop a new test to measure xenoestrogens in water, based on a measure of the estrogen-activated genes that are switched on when cells are exposed to estrogens. If the research is successful, it will produce the best test in the world for measuring the effects of xenoestrogens on mammalian cells. The test can be used to develop better xenoestrogen removal processes, and to set limits for the levels of xenoestrogens permitted in rivers and creeks.Read moreRead less
