The results of the trial monitoring indicate that mallard and black duck wings are satisfactory monitoring media, that pesticidal residues were present in all pools, and that due to the variability in levels, the pool size should not be reduced from 25 wings unless there is a wing shortage. Differences in DDE residues between adult and immature wings of both species indicate that the age classification should be maintained in sampling. For analytical reasons, State identification will be necessary in nation-wide monitoring even though significant residue differences between New York and Pennsylvania wings were not demonstrated.
试验监测结果表明，野鸭和黑鸭翅膀是令人满意的监测媒介，所有水池中都存在农药残留，而且由于水平变化，除非翅膀短缺，否则不应减少每个水池 25 只翅膀的数量。两种鸟类的成体和幼体翅膀之间 DDE 残留量的差异表明，在采样中应保持年龄分类。出于分析原因，即使没有证明纽约州和宾夕法尼亚州翅膀之间存在显著的残留差异，全国性监测也需要州识别。
