The concentrations of polycyclic aromatic hydrocarbons and heavy metals were evaluated in shallow sediments, water, fish and seabird samples from the Cispata Bay, Colombia. The heavy metals concentrations in the sediment was in the following order: Cu>Pb>Hg>Cd. The heavy metal concentration was different (p<0.05) in juvenile and adult birds. High concentrations of mercury were registered in the seabird (10.19±4.99mgkg) and fish (0.67μgg) samples. The total concentration of polycyclic aromatic hydrocarbons ranged from 7.0-41ngg in sediment, 0.03-0.34ngmL in water samples, 53.24ngg in fish, and 66ngg in seabirds. The high concentrations of heavy metals in seabirds may be explained by their feeding habits. The presence of polycyclic aromatic hydrocarbons in the Cispata Bay may be due to hydrocarbon spills during oil transport at the nearby oil port.
对来自哥伦比亚锡斯帕塔湾的浅层沉积物、水、鱼类和海鸟样本中的多环芳烃和重金属浓度进行了评估。沉积物中的重金属浓度顺序如下：铜>铅>汞>镉。幼鸟和成年鸟体内的重金属浓度存在差异（p<0.05）。海鸟（10.19±4.99mg/kg）和鱼类（0.67μg/g）样本中汞的浓度较高。沉积物中多环芳烃的总浓度范围为7.0 - 41ng/g，水样中为0.03 - 0.34ng/mL，鱼类中为53.24ng/g，海鸟中为66ng/g。海鸟体内重金属浓度较高可能与其觅食习性有关。锡斯帕塔湾中多环芳烃的存在可能是由于附近油港石油运输过程中的烃类泄漏。
