大规模的国际监测研究对于评估全球范围内有机卤化污染物的排放模式和环境分布非常重要。在这项研究中，OHCs的存在进行了调查，在三个大陆（欧洲，北美和澳大拉西亚），使用椋鸟（Sturnus vulgaris和Sturnus unicolor）的鸡蛋，以评估其是否适合大规模的监测研究。据我们所知，这是第一次使用同一物种的鸟蛋作为洲际范围内OHC的生物监测器。我们发现，除了六氯环己烷（HCHs）外，不同采样地点的卵中OHC浓度存在显著差异。鸡蛋中多氯联苯（PCB）的平均总浓度从澳大利亚的78 - 26纳克/克脂重（脂重）到美国的2900 +/- 1300纳克/克脂重不等。在所有地点，多氯联苯的分布都以CB 153和CB 138为主，但新西兰除外，新西兰的CB 95、CB 101和CB 149的分布也很高。加拿大的多溴二苯醚平均总浓度最高（4，400 +/- 830纳克/克脂重），而西班牙的多溴二苯醚平均浓度最低（3.7 +/- 0.1纳克/克脂重）。在所有国家，椋鸟蛋中的多溴二苯醚分布都以BDE 47和BDE 99为主，但在比利时，溴化程度较高的多溴二苯醚所占比例高于其他国家。就有机氯农药而言，二氯二苯基三氯乙烷的浓度范围从法国的110 +/- 16纳克/克脂重到新西兰的17，000 +/-3，400纳克/克脂重不等，而六氯环己烷和六氯苯在所有取样地点的浓度普遍较低。美国鸡蛋中的氯丹含量非常高（2，500 +/-1，300纳克/克脂重）。所有国家的OCP概况主要由p，p '-DDE主导。在一般情况下，我们观察到的世界范围内的趋势，在椋鸟蛋是根据人类和环境的OHC数据，这表明，有可能使用椋鸟蛋作为生物监测工具在大的地理范围内的文献。(C)2012爱思唯尔有限公司保留所有权利。
Large-scale international monitoring studies are important to assess emission patterns and environmental distributions of organohalogenated contaminants (OHCs) on a worldwide scale. In this study, the presence of OHCs was investigated on three continents (Europe, North America and Australasia), using eggs of starlings (Sturnus vulgaris and Sturnus unicolor) to assess their suitability for large-scale monitoring studies. To the best of our knowledge, this is the first study using bird eggs of the same species as a biomonitor for OHCs on an intercontinental scale. We found significant differences in OHC concentrations of the eggs among sampling locations, except for hexachlorocyclohexanes (HCHs). Mean concentrations of sum polychlorinated biphenyls (PCBs) in eggs ranged from 78 26 ng/g lipid weight (lw) in Australia to 2900 +/- 1300 ng/g lw in the United States. The PCB profile was dominated by CB 153 and CB 138 in all locations, except for New Zealand, where the contribution of CB 95, CB 101 and CB 149 was also high. The highest mean sum polybrominated diphenyl ether (PBDE) concentrations were found in Canada (4400 +/- 830 ng/g lw), while the lowest mean PBDE concentrations were measured in Spain (3.7 +/- 0.1 ng/g lw). The PBDE profile in starling eggs was dominated by BDE 47 and BDE 99 in all countries, but in Belgium, the higher brominated PBDEs had a higher contribution compared to other countries. For the organochlorine pesticides (OCPs), dichlorodiphenyltrichloroethanes (DDTs) ranged from 110 +/- 16 ng/g lw in France to 17,000 +/- 3400 ng/g lw in New Zealand, while HCHs and hexachlorobenzene were generally in low concentrations in all sampling locations. Chlordanes were remarkably high in eggs from the United States (2500 +/- 1300 ng/g lw). The OCP profile in all countries was largely dominated by p,p'-DDE. In general, the worldwide trends we observed in starling eggs were in accordance with the literature on human and environmental OHC data, which suggests that there is potential for using starling eggs as a biomonitoring tool on a large geographical scale.
