Organic pollutants (OPs) represent a wide range of chemicals that are potentially harmful for human and wildlife health. Many of these pollutants have been identified as endocrine disruptors that can alter hormonal balance producing adverse biological effects such as neurotoxicity, reproductive disorders, carcinogenicity and hepatotoxicity. For years, hair has been selected as a non-invasive source to assess levels of animal contamination. In the present study, a multiclass screening method for determining about 60 organic pollutants in pet hair was designed and validated for qualitative and quantitative purposes. Concentrations from different classes of organochlorine, and organophosphate pesticides (OCPs, and OPPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (NDL-PCBs and DL-PCBs), polybrominated diphenyl ethers (PBDEs) and organophosphate esters (OPEs) were identified in the selected pet hair samples from Ourense (NW, Spain). We detected most of these pollutants in the selected hair pets. The mean concentrations found ranged from 89 to 6556ng/g for OPEs, from 8.6 to 1031ng/g for PAHs, from 8.6 to 256ng/g for PBDEs, from 29 to 184ng/g for OPPs, from 0.29 to 139 for OCPs, from 0.30 to 59ng/g for NDL-PCBs and from 1.2 to 14ng/g for DL-PCBs. To our knowledge, this is the first study to document the presence of OPs in pets from North-West Spain and it could provide baseline information for future monitoring of OPs in the area.
有机污染物（OPs）代表了广泛的化学物质，这些化学物质可能对人类和野生动物的健康有害。其中许多污染物已被确定为内分泌干扰物，它们可以改变激素平衡，产生神经毒性、生殖障碍、致癌性和肝毒性等不良生物学效应。多年来，毛发一直被选为评估动物污染水平的非侵入性来源。在本研究中，设计并验证了一种用于定性和定量测定宠物毛发中约 60 种有机污染物的多类筛查方法。在来自西班牙西北部奥伦塞的选定宠物毛发样本中，鉴定出了不同类别的有机氯和有机磷农药（OCPs 和 OPPs）、多环芳烃（PAHs）、多氯联苯（NDL-PCBs 和 DL-PCBs）、多溴二苯醚（PBDEs）和有机磷酸酯（OPEs）。我们在选定的宠物毛发中检测到了这些污染物中的大多数。发现的平均浓度范围从 OPEs 的 89 到 6556ng/g，从 PAHs 的 8.6 到 1031ng/g，从 PBDEs 的 8.6 到 256ng/g，从 OPPs 的 29 到 184ng/g，从 OCPs 的 0.29 到 139ng/g，从 NDL-PCBs 的 0.30 到 59ng/g，从 DL-PCBs 的 1.2 到 14ng/g。据我们所知，这是首次记录西班牙西北部宠物中存在 OPs 的研究，它可以为该地区未来监测 OPs 提供基线信息。
