Ten organochlorine compounds were identified in pools of black duck (Anas rubripes) and mallard (A. platyrhynchos) wings from the 1981-82 hunting season. Most organochlorine compounds occurred very infrequently. Among those compounds positively identified by mass spectrometry, DDE and, secondarily, PCB had the highest frequencies of occurrence. Other compounds, positively identified and occurring less frequently, included DDT, DDD, DDMU, dieldrin, heptachlor epoxide, trans-nonachlor, cis-chlordane and mirex. Compounds looked for but not positively identified include oxychlordane, cis-nonachlor, endrin, hexachlorobenzene and toxaphene. PCB levels in black duck wings declined between the 1979-80 and 1981-82 collections. PCB levels in black duck wings from the northern region of the Atlantic Flyway were higher than those in wings from the southern region. Mean DDE residues in mallard wings declined between collections and differed among flyways and regions. PCB levels in mallard wings differed only among flyways and regions.
1981-82 狩猎季，从黑鸭（Anas rubripes）和绿头鸭（A. platyrhynchos）翅膀的样本中鉴定出了 10 种有机氯化合物。大多数有机氯化合物很少出现。在通过质谱法确证的化合物中，DDE 和其次的 PCB 出现的频率最高。其他被确证且出现频率较低的化合物包括 DDT、DDD、DDMU、狄氏剂、七氯环氧化物、反式-非六氯、顺式-氯丹和灭蚁灵。寻找但未确证的化合物包括氧氯丹、顺式-非六氯、艾氏剂、六氯苯和毒杀芬。1979-80 年和 1981-82 年采集的黑鸭翅膀中 PCB 水平有所下降。大西洋飞行航道北部地区黑鸭翅膀中的 PCB 水平高于南部地区。绿头鸭翅膀中的 DDE 残留量在两次采集之间下降，并且在飞行航道和地区之间存在差异。绿头鸭翅膀中的 PCB 水平仅在飞行航道和地区之间存在差异。
