Behavior of the mosquitofish (Gambusia affinis) toward the Japanese medaka (Oryzias latipes) was tested under exposure to environmental 17α-ethinylestradiol (EE2), a synthetic derivative of natural estrogen, estradiol. The mosquitofish were exposed to EE2 at different concentrations-0, 0.5, 5.0, and 50.0 ng/L-for 2 days, before their behavioral changes(More)
The formation of hydroxyl radicals (•OHs) by aquatic plants was investigated using electron-spin-resonance (ESR) spectroscopy and fluorescence microscopy. ESR observations, using 5- (diethoxyphosphoryl)-5-methyl-pyrroline N-oxide as a trapping agent, indicated that the signals produced by aquatic plants ground with ferrous iron ions are almost identical to(More)
