Photoaldrin, photodieldrin, and photoheptachlor are more toxic than their corresponding parent compounds (aldrin, dieldrin, and heptachlor) to freshwater invertebrates and vertebrates, and to adult houseflies. The increase in toxicity is very significant in the case of the amphipod, Gammarus (1 .5 -12 times), bluegill fry (3.6 5.7 times), mosquito larvae, Aedas (2 .3 -6 times), minnow fry (2.5 ...
A number of metabolites of 17beta-estradiol were tested for their estrogenic activity using the ER-CA-LUX assay based on the increased expression of luciferase in exposed T47D breast cancer cells. E2beta and estrone showed similar potencies in the test, whereas E2alpha was 100 times less active. Incubation of cells with estrone (0.35 microM) resulted in the formation of E2beta, whereas the reve...
