Organochlorine pesticide and PCB residues in starlings from 126 sites within the contiguous 48 states were monitored during fall 1976. The average nationwide level of DDE and PCBs has increased significantly since 1974, but the number of sites reporting PCB residues has decreased fivefold. Dieldrin residues have remained unchanged since 1974. Highest DDE levels occurred in samples from parts of Arizona, Arkansas, California, Louisiana, and New Mexico.
1976年秋季，对美国本土48个州126个地点的椋鸟体内有机氯农药和多氯联苯残留情况进行了监测。自1974年以来，全国范围内滴滴涕和多氯联苯的平均含量显著增加，但报告有多氯联苯残留的地点数量减少了五倍。自1974年以来，狄氏剂残留量一直保持不变。滴滴涕含量最高的样本来自亚利桑那州、阿肯色州、加利福尼亚州、路易斯安那州和新墨西哥州的部分地区。
