Organochlorine residues in wings of adult mallards and black ducks were monitored during the 1972-73 hunting season. DDE, DDT, DDD, dieldrin, and polychlorinated biphenyls (PCB's) were present in all samples. Mallard wings from Alabama contained the highest mean levels of DDE, DDT, DDD, dieldrin, and PCB's. Mallards and black ducks from the Atlantic Flyway and mallards from the Pacific Flyway contained significantly lower DDE residues than in 1969-70. Black ducks from the Atlantic Flyway contained significantly less dieldrin than in 1969-70, and mallards in the Central and Pacific Flyways contained significantly lower levels of PCB's. As in 1969-70, DDE residues were lowest in the Central Flyway and highest in the Atlantic Flyway. The average PCB level remained unchanged in the Atlantic Flyway but was higher in the Mississippi Flyway than in 1969-70, probably because of the unusually high levels in Alabama samples. All organochlorine residues in black ducks from the Atlantic Flyway significantly correlated. DDE concentrations in mallards from the Atlantic Flyway significantly correlated with those of DDT, DDD, and PCB's.
在1972 - 1973年狩猎季节期间，对成年绿头鸭和黑鸭翅膀中的有机氯残留进行了监测。所有样本中均存在滴滴伊（DDE）、滴滴涕（DDT）、滴滴滴（DDD）、狄氏剂和多氯联苯（PCB）。来自阿拉巴马州的绿头鸭翅膀中，滴滴伊、滴滴涕、滴滴滴、狄氏剂和多氯联苯的平均含量最高。来自大西洋飞行路线的绿头鸭和黑鸭以及来自太平洋飞行路线的绿头鸭，其滴滴伊残留量明显低于1969 - 1970年。来自大西洋飞行路线的黑鸭所含狄氏剂明显少于1969 - 1970年，而来自中部和太平洋飞行路线的绿头鸭所含多氯联苯水平明显更低。与1969 - 1970年一样，中部飞行路线的滴滴伊残留量最低，大西洋飞行路线的最高。大西洋飞行路线的多氯联苯平均水平保持不变，但密西西比飞行路线的高于1969 - 1970年，这可能是因为阿拉巴马州样本中的含量异常高。来自大西洋飞行路线的黑鸭体内所有有机氯残留量显著相关。来自大西洋飞行路线的绿头鸭体内的滴滴伊浓度与滴滴涕、滴滴滴和多氯联苯的浓度显著相关。
