A large portion of organic pollutants (OPs) represent a potential hazard to humans and living beings due to their toxic properties. For several years, birds have been used as biomonitor species of environmental pollution. Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated biphenyl ethers (PBDEs), organophosphate pesticides (OPPs), polycyclic aromatic hydrocarbons (PAHs) and pyrethroids (PYRs) were assessed in body feather samples of 71 feral pigeons (Columba livia domestica) collected from Asturias and Galicia (NW Spain). The percentage of detection for all chemical groups were above 90 % in studied birds. The general pattern was dominated by PAHs (mean value ± standard deviation (SD) 32 ± 15 ng/g) followed by OCPs (3.8 ± 1.1 ng/g), PYRs (3.4 ± 3.8 ng/g), PCBs (1.6 ± 1.0 ng/g), OPPs (1.3 ± 0.70 ng/g) and PBDEs (0.80 ± 0.30 ng/g). Significant differences were observed between age, location and gender suggesting different sources of exposure and accumulation pathways.

大部分有机污染物（OPs）由于其毒性而对人类和生物造成潜在危害。几年来，鸟类已被用作环境污染的生物监测物种。多氯联苯（PCBs），有机氯农药（有机氯农药），聚溴联苯醚（PBDE），有机磷酸酯杀虫剂（有机磷），多环芳香烃（PAHs）和拟除虫菊酯（PYRs）的71只野鸽体羽毛样品中进行了评估（鸽利维娅家蝇）收集自阿斯图里亚斯和加利西亚（NW西班牙）。在研究的鸟类中，所有化学组的检出百分比均超过90％。一般模式主要由PAH（平均值±标准偏差（SD）32±15 ng / g），OCP（3.8±1.1 ng / g），PYR（3.4±3.8 ng / g），PCB（1.6±1.0）主导ng / g），OPP（1.3±0.70 ng / g）和PBDEs（0.80±0.30 ng / g）。在年龄，位置和性别之间观察到显着差异，表明暴露和积累途径的不同来源。
