摘要
采用化学和毒理学方法对 2021 年从波罗的海南部(波兰地区)六个地点采集的表层沉积物进行了检测。化学分析包括多溴联苯醚(PBDEs)、多环芳烃(PAHs)及其烷基化衍生物、丁基锡化合物以及 16 种主要和微量元素。使用 Ostracodtoxkit F 和 Microtox 对毒性进行了测量。沉积物的生态风险通过危险商数(HQ)计算进行估算。格但斯克深海和沉船附近沉积物中的一些多环芳烃、烷基化多环芳烃和金属(锌、汞、镉和砷)可能会造成中度风险,但所有分析化合物的存在对这些沉积物造成的风险被认为很高。在使用生物试验进行的研究中,"弗兰肯 "号沉船和斯沃普斯克毛坑附近的沉积物对试验生物具有很高的毒性。与 Microtox 相比,Ostracodtoxkit F 似乎是一种对所测化合物更为敏感的检测方法。
Contaminant levels versus toxicity bioassays in ecological risk assessment of sediments from the southern baltic sea
Surface sediments collected in 2021 from six locations in the southern Baltic Sea (Polish district) were examined by chemical and toxicological methods. Chemical analyses included polybrominated diphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), and their alkylated derivatives, butyltin compounds and 16 major and trace elements. The toxicity was measured using Ostracodtoxkit F and Microtox. The ecological risk of sediment was estimated by hazard quotient (HQ) calculation. Some PAHs, alkylated PAHs and metals (Zn, Hg, Cd and As) could pose a moderate risk in the sediments from the Gdańsk Deep and in the vicinity of the wrecks, but the risk resulting from the presence of all analyzed compounds was considered high for these sediments. In studies using biotests, sediments from the vicinity of the t/s Franken wreck and the Słupsk Furrow were highly toxic to test organisms. Ostracodtoxkit F, compared to Microtox, appeared a more sensitive test for measured compounds.
期刊介绍:
Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes.
Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following:
– The extent, persistence, and consequences of change and the recovery from such change in natural marine systems
– The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems
– The biogeochemistry of naturally occurring and anthropogenic substances
– Models that describe and predict the above processes
– Monitoring studies, to the extent that their results provide new information on functional processes
– Methodological papers describing improved quantitative techniques for the marine sciences.
