Short-chain chlorinated paraffins (SCCPs) are under review by the Stockholm Convention on Persistent Organic Pollutants. Currently, limited data are available about SCCPs in terrestrial organisms. In the present study, SCCP concentration in the muscles of seven terrestrial bird species (n = 38) inhabiting an e-waste recycling area in South China was determined. This concentration varied from 620 to 17,000 ng/g lipid. Resident birds accumulated significantly higher SCCP concentrations than migratory birds (p < 0.01). Trophic magnification was observed for migratory bird species but not for resident, which was attributed to high heterogeneity of SCCP in e-waste area. Two different homologue group patterns were observed in avian samples. The first pattern was found in five bird species dominated by C10 and C11 congeners, while the second was found in the remains, which show rather equal abundance of homologue groups. This may be caused by two sources of SCCPs (local and e-waste) in the study area.
短链氯化石蜡（SCCPs）正在接受《关于持久性有机污染物的斯德哥尔摩公约》的审查。目前，有关陆地生物体内 SCCPs 的数据有限。本研究测定了栖息在中国南方电子废物回收区的 7 种陆地鸟类（n=38）肌肉中的 SCCP 浓度。该浓度范围为 620 至 17000ng/g 脂质。居留鸟类的 SCCP 浓度明显高于候鸟（p<0.01）。观察到候鸟的营养级放大效应，但在居留鸟类中没有观察到，这归因于电子废物区 SCCP 的高度异质性。在鸟类样本中观察到两种不同的同系物组模式。第一种模式存在于 5 种以 C10 和 C11 同系物为主的鸟类中，而第二种模式存在于残留物中，同系物组的丰度相当。这可能是由于研究区域存在两种 SCCP 来源（本地和电子废物）。
