The aim of this study was to determine the levels of different inorganic elements (lead [Pb], mercury [Hg], and arsenic [As]) and persistent chlorinated pollutants (including polychlorinated biphenyls [PCBs] and organochlorine pesticides [OCPs]) in blood and plasma of White stork (Ciconia ciconia) nestlings from northwest (NW) Spain. The concentrations of PCBs were lower than the limit of detection in all samples. The OCPs γ-HCH, 4,4'-DDE, HCB, and endosulfan were detected most frequently in plasma from White stork nestlings. These OCPs were detected in 98, 54, 39, and 37 % of all samples, respectively. However, the concentrations of organic pollutants were lower than the risk thresholds for birds. The mean levels of the inorganic elements Pb, Hg, and As were found to be 36.92 ± 33.48, 16.48 ± 12.87, and 9.813 ± 13.84 µg/L, respectively. These levels were also lower than the risk thresholds for birds. This study not only provides a snapshot of the levels of both inorganic and organic contaminants in wild White storks in NW Spain, it also provides a useful baseline for biomonitoring levels of the measured contaminants in this area.
本研究的目的是测定西班牙西北部白鹳雏鸟血液和血浆中不同无机元素（铅[Pb]、汞[Hg]和砷[As]）以及持久性氯化污染物（包括多氯联苯[PCBs]和有机氯农药[OCPs]）的含量。所有样本中多氯联苯的浓度均低于检测限。有机氯农药γ-六氯环己烷、4,4'-滴滴伊、六氯苯和硫丹在白鹳雏鸟血浆中检出频率最高。这些有机氯农药在所有样本中的检出率分别为98%、54%、39%和37%。然而，有机污染物的浓度低于鸟类的风险阈值。无机元素铅、汞和砷的平均含量分别为36.92±33.48、16.48±12.87和9.813±13.84μg/L。这些含量也低于鸟类的风险阈值。本研究不仅提供了西班牙西北部野生白鹳体内无机和有机污染物含量的概况，还为该地区所测污染物的生物监测水平提供了有用的基线。
