作者报告1983年在美国Kesterson国家野生生物保护区(NWR)出现水鸟胚胎死亡和明显的畸胎发生,这是由于Kesterson水库受到高浓度硒的农业废水污染,并且以此水排放灌溉的结果。选择347个鸟巢及巢内1681个鸟卵,做好标记,观察鸟卵孵化过程,从孵化期或孵不出的鸡蛋收集胚胎,对照区设在10Km以外的Volta野生生物区,从1683～1685年间选择95个鸟巢及巢内424个鸟卵,进行
The authors report that waterfowl embryonic death and apparent teratogenicity occurred in the Kesterson National Wildlife Refuge (NWR) in the United States in 1983, as a result of the Kesterson Reservoir being contaminated with high concentrations of selenium-containing agricultural wastewaters and using this water to discharge irrigation. A total of 1681 bird eggs from 347 nests and nests were selected and labeled to observe the process of bird egg hatching. Embryos were collected from the hatching or hatching eggs. The control area was set up in the Volta wildlife area 10Km away from 1683 to 1685 During the year, 95 bird nests and 424 bird eggs were selected for nesting
