摘要
探索薄膜中的扩散梯度(DGT)作为水产养殖水域金属智能生物监测的替代品的能力很有意义。研究人员在沿海养殖水域进行了扇贝 Argopecten irradians 的 DGT 部署和移植实验。结果表明,DGT 标记的金属浓度在养殖水域中相对稳定,且浓度由高到低依次为:Zn > Ni > Cu > Zn > Ni > Cu > Zn > Ni > Cu > Zn:Zn > Ni > Cu > Pb ≈ Cd。辐照扇贝从周围水生环境中吸收所研究金属的能力各不相同。重要的是,它表明 DGT 比扇贝的生物监测反应更快。总之,该研究建议将 DGT 技术作为快速监测养殖水域金属污染的方法,并为 DGT 技术的标准化奠定了基础。此外,该研究还表明,高有机物可能对 DGT 的可溶性浓度有很大影响,这一点有待进一步研究。
Use of the diffusive gradients in thin-films (DGT) technique for smart rapid biomonitoring of trace metals in aquaculture systems.
It is of interest to explore the capabilities of the diffusive gradients in thin-films (DGT) as a substitute for smart biomonitoring of metals in aquaculture waters. DGT deployment and transplantation experiments of scallops Argopecten irradians were carried out in the coastal aquaculture waters. The results showed that DGT-labile metal concentrations were relatively stable in the aquaculture and they were in descending order: Zn > Ni > Cu > Pb ≈ Cd. The scallop A. irradians exhibited different abilities of taking up the studied metals from the ambient aquatic environment. Importantly, it demonstrated that DGT responded quicker than biomonitoring of scallops. Overall, it suggested DGT technique as a rapid monitoring method for metal contamination in aquaculture waters and laid a foundation for the standardization of the DGT technique. Besides, it suggested that high organic matter may have a great influence on DGT-labile concentrations, which should be investigated in more detail.
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.
