In 1973, 119 bats of three species were collected from four localities in Maryland and West Virginia. The collection included 43 big brown bats (Eptesicus fuscus), 43 little brown brown bats (Myotis lucifugus), and 33 eastern pipistrelles (Pipistrellus subflavus). The bats were collected from Round Top Mountain, Washington Co., Md.; Trout Cave, Pendleton Co., W. Va.; Montpelier Barn, Prince Georges Co., Md. Residues of sigmaDDT were highest in carcasses of bats from Round Top Mountain, which is surrounded by apple orchards. Bats from Trout Cave had the lowest residues, a circumstance which probably reflects the absence of agriculture and industry in the area. A polychlorinated biphenyl (PCB) and oxychlordane were highest at Montpelier Barn. Sources of the PCB are unknown, but chlordane is used against termites and in gardening at nearby housing developments. Residues in bats from North East Methodist Church were low except for dieldrin. Among species, little brown bats usually had the highest residue concentrations in their carcasses, whereas big brown bats had the lowest. When DDE in carcass fat of all species was above 60-90 ppm, it became measurable in brain tissue. Above 60-90 ppm, DDE levels in brains rose with increasing levels in carcass lipids. Residues of the PCB tended to respond similarly. Residue levels in brains were greatest in little brown bats; the maximum level of the PCB, 7.9 Ppm, was more than twice that of DDE.
1973年，从马里兰州和西弗吉尼亚州的四个地点收集了119只三种蝙蝠。此次收集包括43只大棕蝠（棕蝠属）、43只小棕蝠（鼠耳蝠属）和33只东部伏翼（淡黄伏翼）。这些蝙蝠分别采自马里兰州华盛顿县的圆顶山；西弗吉尼亚州彭德尔顿县的鳟鱼洞；马里兰州乔治王子县的蒙彼利埃谷仓。在被苹果园环绕的圆顶山捕获的蝙蝠尸体中，σ-滴滴涕的残留量最高。鳟鱼洞的蝙蝠残留量最低，这种情况可能反映了该地区没有农业和工业。多氯联苯（PCB）和氧氯丹在蒙彼利埃谷仓的含量最高。PCB的来源不明，但氯丹用于防治白蚁和附近房屋开发项目的园艺中。除狄氏剂外，东北卫理公会教堂蝙蝠的残留量较低。在不同物种中，小棕蝠尸体中的残留浓度通常最高，而大棕蝠的残留浓度最低。当所有物种尸体脂肪中的滴滴伊含量高于60 - 90 ppm时，在脑组织中就可检测到。高于60 - 90 ppm时，脑组织中的滴滴伊水平随尸体脂质水平的升高而升高。PCB的残留情况也有类似趋势。小棕蝠脑组织中的残留水平最高；PCB的最高含量为7.9 ppm，是滴滴伊的两倍多。
