The organochlorine insecticide aldrin is commonly used in intensive agriculture, and demonstrates estrogenic activity. Rotifers such as Brachionus calyciflorus are favored test animals in aquatic toxicology because of their more sensitivity to most toxicants. In the tested concentration range of 0.04-1.28 mg/L, aldrin shortened significantly the durations of embryonic development. Lower concentrations of aldrin had an intriguing effect on the reproduction of the rotifers and are beneficial to their survival. Different endpoints of both development and reproduction had different sensitivity to aldrin. The reproductive endpoint of the rotifers is more sensitive to aldrin than the developmental endpoint.
有机氯杀虫剂艾氏剂常用于集约农业，并具有雌激素活性。诸如萼花臂尾轮虫之类的轮虫由于对大多数毒物更为敏感，因而成为水生毒理学中备受青睐的实验动物。在0.04 - 1.28毫克/升的测试浓度范围内，艾氏剂显著缩短了胚胎发育的时长。较低浓度的艾氏剂对轮虫的繁殖产生了有趣的影响，并且有利于它们的存活。发育和繁殖的不同终点对艾氏剂的敏感性各异。轮虫的繁殖终点对艾氏剂比发育终点更为敏感。
