Abstract：
Monitoring wildlife exposure to biological hazards is a critical component of the wildlife risk assessment. In this study 38 hair samples were collected from 8 different species from ten districts of Russian Far East and Siberia and analysed for the presence of organochlorine pesticides (OCP). 50% of the samples were contaminated with - p, p\'-DDT, α-HCH and DDD. DDT was the main contaminant found in 13 sample at concentrations range of 14.3 to 369.5 pg/mg hair, mean 91.9 ± 89.7 pg/mg. α-HCH was detected in three samples with the concentrations range 29.9-180.2 pg/mg. The p, p\'-DDD was found only in one hair sample of Siberian roe deer from Altai region at 52.6 pg/mg. The exposure level is depended on animals habitat location. The most contaminated region is Terney district which is in the proximity to the borders with China and North Korea where OCP are still in use.
摘要：
监测野生动物暴露于生物危害是野生动物风险评估的重要组成部分。在这项研究中，从俄罗斯远东和西伯利亚十个地区的8个不同物种中收集了38个头发样本，并分析了有机氯农药（OCP）的存在。50%的样品被-p污染，p\'-滴滴涕,α-HCH和DDD。滴滴涕是13个样品中发现的主要污染物，浓度范围为14.3至369.5pg/mg头发，平均91.9±89.7pg/mg。在三个样品中检测到α-HCH，浓度范围为29.9-180.2pg/mg。P,p'-DDD仅在来自阿尔泰地区的西伯利亚ro的一个头发样本中以52.6pg/mg被发现。暴露水平取决于动物栖息地的位置。污染最严重的地区是Terney地区，该地区靠近中国和朝鲜的边界，OCP仍在使用。
