In this study we investigated the accumulation of polychlorobiphenyls (PCBs), polychlorodibenzo-p-dioxins (PCDDs), polychlorodibenzofurans (PCDFs), and the chlorinated pesticides 1,1-dichloro-2,2-bis(4-chlorophenyl)-ethene (DDE), 1,1,1-trichloro-2,2-bis(4-chlorophenyl)-ethane (DDT), and hexachlorobenzene (HCB) in the breast muscle, liver, lung, heart and brain tissues of adult common swifts (Apus apus, a long-lived aerial feeder bird). Individuals were collected in an urban area located in Rome during the breeding period. As shown by lipid-base normalized data, in general analytes had a significant minimum concentration in the brain. PCDD and PCDF concentration values in such tissue were approximately one order of magnitude lower than those found in breast muscle, heart, and lung tissues, and as much as two orders of magnitude below the relatively high levels found in the liver. PCB levels followed the same accumulation patterns. Of all analytes, HCB exhibited the most uniform distribution pattern over the five matrices assayed. DDE and DDT were by far the most and the least concentrated pesticide. In the urban environment of Rome, an air-to-swift bioconcentration factor (lipid based) in the order of 5 x 10(6) (2 x 10(5), fresh tissue base) was estimated for PCDDs and PCDFs. Our study suggests that airborne arthropod feeders, such us the common swift, are suitable biomonitors for air quality assessment.
在本研究中，我们调查了多氯联苯（PCBs）、多氯二苯并 - 对 - 二噁英（PCDDs）、多氯二苯并呋喃（PCDFs）以及氯化农药1,1 - 二氯 - 2,2 - 双（4 - 氯苯基）乙烯（DDE）、1,1,1 - 三氯 - 2,2 - 双（4 - 氯苯基）乙烷（DDT）和六氯苯（HCB）在成年普通雨燕（Apus apus，一种长寿的空中觅食鸟类）的胸肌、肝脏、肺、心脏和脑组织中的蓄积情况。在繁殖期于罗马市区收集了个体样本。脂质归一化数据显示，一般来说，分析物在脑中的最低浓度显著。该组织中PCDD和PCDF的浓度值比在胸肌、心脏和肺组织中发现的值低约一个数量级，比在肝脏中发现的相对较高水平低多达两个数量级。PCB水平遵循相同的蓄积模式。在所有分析物中，HCB在测定的五种基质中表现出最均匀的分布模式。DDE和DDT分别是浓度最高和最低的农药。在罗马的城市环境中，估计PCDDs和PCDFs的空气到雨燕生物浓缩因子（基于脂质）约为5×10⁶（基于新鲜组织为2×10⁵）。我们的研究表明，像普通雨燕这样的空中节肢动物捕食者是评估空气质量的合适生物监测器。
