Eighty-six bald eagles found sick or dead during 1973-74 in 24 States were analyzed for organochlorine compounds. DDE was detected in all caracasses; polychlorinated biphenyls (PCB's) were found in all but two. Seventy-five carcasses contained TDE and/or dieldrin. Four eagles had possibly lethal levels of dieldrin in the brain. Bald eagles continue to retain high residue levels of organochlorine pollutants. Illegal shooting remained the most common cause of death but accounted for a smaller percentage of the mortalities than in the two previous biennial collections.
1973年至1974年间，在24个州发现的86只生病或死亡的白头海雕被用于分析有机氯化合物。在所有尸体中均检测到了滴滴伊；除两具外，在其他所有尸体中都发现了多氯联苯（PCBs）。75具尸体含有反式滴滴涕和/或狄氏剂。有四只白头海雕大脑中的狄氏剂含量可能达到了致死水平。白头海雕体内仍残留着高含量的有机氯污染物。非法射杀仍然是最常见的死亡原因，但在死亡总数中所占的比例比前两次两年期统计中的比例要小。
