The risk of marine organisms ingesting plastics has become a growing concern due to hazard chemicals in plastics. To identify compounds to which seabirds potentially have substantial exposure, 194 plastics fragments and pellets ingested by seabirds, i.e., northern fulmars from the Faroe Islands, and laysan albatross and black-footed albatross from Mukojima Island, were analyzed piece by piece. Four kinds of UV stabilizers, 2 brominated flame retardants, and styrene oligomers were detected at detection frequencies of 4.6%, 2.1%, and 2.1%, respectively. Concentrations ranging from not detected (n.d.) - 1700 μg/g were measured for UV stabilizers, n.d. - 1100 μg/g for flame retardants, and n.d. - 3200 μg/g for styrene oligomers. We found that these chemicals could be retained in plastics during drifting and fragmentation in the ocean and transported to seabirds. This type of transport via plastics can be direct pathway that introduces hazardous compounds to marine organisms.
由于塑料中存在危险化学品，海洋生物摄入塑料的风险已成为一个日益严重的问题。为了确定海鸟可能大量接触的化合物，我们对 194 块塑料碎片和颗粒进行了分析，这些碎片和颗粒是从法罗群岛的北方塘鹅、以及从屋久岛的笠岛信天翁和黑脚信天翁体内取出的。我们检测到了 4 种紫外线稳定剂、2 种溴化阻燃剂和苯乙烯低聚物，检出频率分别为 4.6%、2.1%和 2.1%。紫外线稳定剂的浓度范围为未检出（n.d.）至 1700μg/g，阻燃剂的浓度范围为 n.d. 至 1100μg/g，苯乙烯低聚物的浓度范围为 n.d. 至 3200μg/g。我们发现，这些化学物质可能在海洋中漂流和碎裂过程中保留在塑料中，并被运输到海鸟体内。这种通过塑料进行的运输可能是一种将危险化合物引入海洋生物的直接途径。
