The exposure to environmentally relevant chlorpyrifos concentrations (0.03, 0.06 and 0.12 µg chlorpyrifos L⁻¹) causes increases in precopulatory guardian behavior time, amplexus reformulation after exposure and in the number of ovigerous females in the amphipod Hyalella curvispina. Effects in incubation period, effective hatching and median lethal concentration on the decapods Macrobrachium borellii and Aegla uruguayana, both in adults and embryos, were achieved at higher concentrations than those found in the environment. Environmentally relevant chlorpyrifos concentrations appear not to affect decapods but several effects in reproductive traits of amphipods were observed.

暴露于与环境有关的毒死（浓度（0.03、0.06和0.12 µg毒死− L ^-1）会导致交配前监护人的行为时间，暴露后两栖动物的重新配制以及两足纲透明藻透明卵中雌性卵的数量增加。效应潜伏期，有效阴影和中值致死浓度在十足目罗氏沼虾borellii和Aegla乌鲁瓜亚纳，无论是在成人和胚胎，分别在较高浓度比在环境中发现来实现的。与环境有关的毒死concentrations浓度似乎不影响十足纲，但观察到了对两足纲生殖性状的若干影响。
