Environmental problems persist due to mercury from artisanal and small-scale gold mining (ASGM) as well as ecological problems associated with the macrophyte Eichhornia crassipes Martius (EC). Environmental problems persist due to mercury contamination from artisanal and small-scale gold mining (ASGM) and ecological issues related to the macrophyte Eichhornia crassipes Martius (EC). A bioaccumulation study was conducted on mercury-laden wastewater (WWm) from ASGM using a pilot treatment plant, specifically a constructed wetland system (CW) with the macrophyte species EC.

Several studies have already highlighted a possible link between particulate matter (PM) and COVID-19. This work is a brief discussion about the latest findings on this topic, highlighting the gaps in the current results and possible tips for future studies.

With this goal, tests on a semi-full scale Thermophilic Alternate Membrane Biological Reactor (ThAlMBR) were carried out for 12 months. ThAlMBR was applied both on thickened (TBSS) and digested biological sewage sludge (DBSS) with alternating aeration conditions, and emerged: (i) high COD removal yields (up to 90%), (ii) a low specific sludge production (0.
