The release process of microfibers: from surgical face masks into the marine environment

tailieu.vn

To provide a preliminary estimation of the release of microfibers by a surgical mask dumped in the marine environment, we carried out artificial weathering experiments. Moreover, SEM and micro-FTIR analysis carried out onto surgical masks collected from Italian beaches highlighted the same morphological and chemical degradation signature observed in the masks subjected to the artificially weathering experiments, confirming the risks of a similar microfiber release into the marine environment..

Levels of heavy metals in seawater, sediment and in the tissue of Crassostrea belcheri in the western estuary of Ganh Rai bay

tailieu.vn

Heavy metals have reached the marine environment by the different pathways. Some heavy metals enter the sea by the interaction of atmospheric and sea surfaces. The concentration of metals in river water depends on the characteristics of catchments. For this reason, heavy metals in coastal pollution have significant economic and social influences.. Molluscs are the major bottom organisms in the marine ecosystem.
