Wings from woodcock (Philohela minor) were first monitored for organochlorine pesticides and polychlorinated biphenyls (PCBs) in the eastern U.S. in 1971. Regional differences in these compounds were clearly demonstrated and baseline residue levels were obtained for later comparisons. An expanded sampling of wings in 1972 revealed that residues in wings of adult woodcock may differ significantly from those in immatures, and that residues of several important agricultural insecticides and PCBs had declined significantly. More extensive sampling was undertaken in 1975 to determine if changes in residue levels had taken place in the intervening years. PCBs, mirex, and heptachlor epoxide increased significantly between 1972 and 1975 in adult woodcock wings. In immature woodcock wings mirex, dieldrin, and PCBs increased significantly between 1972 and 1975, but DDT residues decreased significantly.
1971 年，首次监测到来自美国东部的丘鹬（Philohela minor）翅膀中的有机氯农药和多氯联苯（PCBs）。明显显示出这些化合物的区域差异，并获得了以后比较的基线残留水平。1972 年对翅膀的扩展采样表明，成年丘鹬翅膀中的残留物质可能与幼鸟的残留物质有很大差异，并且几种重要的农业杀虫剂和 PCBs 的残留物质明显减少。1975 年进行了更广泛的采样，以确定在这几年中残留水平是否发生了变化。在 1972 年至 1975 年期间，成年丘鹬翅膀中的 PCBs、灭蚁灵和七氯环氧化物显著增加。在 1972 年至 1975 年期间，幼鸟丘鹬翅膀中的灭蚁灵、狄氏剂和 PCBs 显著增加，但滴滴涕残留量显著减少。
