1969年至1979年，在14个州收集了秃鹰（Haliaeetus leucocephalus）蛋，并对有机氯农药、多氯联苯和汞进行了分析。在几个地区的鸡蛋中出现了中度的蛋壳变薄。来自切萨皮克湾地区的鸡蛋中大多数有机氯的残留水平最高。在所有鸡蛋中均检测到DDE;其他有机氯检测频率较低。来自缅因州的鸡蛋中汞含量最高。8种污染物与采样养殖区的贝壳厚度或繁殖呈显著负相关; DDE与这些因素关系最密切。当DDE含量为0.3 ppm（湿重）时，繁殖区的幼仔产量接近正常;在蛋中DDE含量>15 ppm的繁殖区，繁殖失败率接近100%。五ppm的DDE与10%的外壳变薄。与这些因素相关的其他污染物也与DDE高度相关;它们的影响与DDE的影响相比似乎很小。
Bald eagle (Haliaeetus leucocephalus) eggs were collected in 14 States in 1969–79 and analyzed for organochlorine pesticides, polychlorobiphenyls, and mercury. Moderate shell thinning occurred in eggs from several areas. Eggs from the Chesapeake Bay area contained the highest residue levels of most organochlorines. DDE was detected in all eggs; other organochlorines were detected less frequently. Mercury levels were highest in eggs from Maine. Eight contaminants were significantly negatively correlated with shell thickness or reproduction at sampled breeding areas; DDE was most closely related to these factors. Production of young was near normal at breeding areas when DDE was ⩽3 ppm (wet weight); reproductive failure approached 100% for those breeding areas where DDE in eggs was >15 ppm. Five ppm DDE was associated with 10% shell thinning. The other contaminants that were associated with these factors were also highly correlated with DDE; their impact appeared minor in relation to those of DDE.
