摘要:
多环芳烃(PAHs)因其致癌性和毒性已引起全球关注。本文旨在回顾和扩展当前对土耳其水环境中PAHs的了解,而土耳其的海洋工业扩张引发了污染问题。为评估与PAHs相关的癌症和生态风险,我们系统地回顾了39篇研究文章。测定平均总PAHs浓度范围为61至249,900 ng/L在表面水中,1至209,400 ng/g在沉积物中,以及4至55,000 ng/g在生物体中。估计的癌症风险来自生物体中的浓度高于来自表面水和沉积物的浓度。尽管后者占主导地位,但从石油源PAHs的负面生态影响估计要大于焦炭源。总体而言,马尔马拉海,爱琴海和黑海高度污染,需要采取补救措施,而有关其他水体的状态仍需要进一步研究。 版权所有© 2023 Elsevier Ltd。保留所有权利。
Polycyclic aromatic hydrocarbons (PAHs) have gathered worldwide attention due to their carcinogenicity and toxicity. This paper aims to review and extend current knowledge on PAHs in aquatic environments in Turkey, where expansion of the marine industry has caused contamination concerns. To assess cancer and ecological risks associated with PAHs, we systematically reviewed 39 research articles. Mean measured concentrations of total PAHs ranged from 61 to 249,900 ng L-1 in surface waters, 1 to 209,400 ng g-1 in sediments, and 4 to 55,000 ng g-1 in organisms. Estimated cancer risks from concentrations in organisms were higher than those from surface waters and sediments. Negative ecosystem impacts of petrogenic PAHs were estimated to be larger than those of pyrogenic origin, despite the predominance of the latter. Overall, the Marmara, Aegean, and Black seas are highly-polluted and need remedial action, while further study is needed to confirm the status of other water bodies.Copyright © 2023 Elsevier Ltd.
