A plan to control mercury emissions to the atmosphere and to establish mercury emission limits has recently been elaborated by the European Commission, making it necessary to devise an efficient and cost effective mercury removal technology. Towards this end wet flue gas desulfurization units appear as a promising option for multi-pollutant control. However, more investigation on mercury removal and a greater mercury removal efficiency are required to achieve this objective. In the present work scrubber chemistry and the application of various solid additives to enhance mercury removal in wet scrubbers is evaluated. The results obtained show a significant correlation between mercury removal efficiency and the pH of the scrubber slurry and SO2 concentration. A weaker correlation was observed between oxygen or slurry concentration and removal efficiency. Finally several solid oxides were found to be effective additives for enhancing mercury capture in wet scrubbers.

Mercury sequestration in alkaline salt low-level radioactive waste.
Environ Sci Pollut Res Int

Savannah River National Laboratory, Aiken, SC, USA.
Liquid low-level radioactive waste at the Savannah River Site contains several species of mercury, including inorganic, elemental, and methylmercury. This waste is solidified and stabilized in a cementitious waste form referred to as saltstone. Soluble mercury is stabilized as β-cinnabar, HgS as the result of reaction between the mercury and sulfur present in blast furnace slag, one of the cementitious reagents.

In this research, fresh pistachio green shell as an agricultural waste was blended with activated carbon to study the adsorption process of mercury (II) from several aqueous solutions with various concentrations. Central Composite Design under Response Surface Methodology was statistically used to consider the independent variables involving pH, contact time, fresh pistachio green shell powder dosage, initial concentration of mercury (II) and activated carbon dosage effects on the mercury (II) removal. pH of 6.

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.

Article Synopsis
- Iron plaques on plant roots can affect the absorption of heavy metals, but the specific role of iron in Robinia pseudoacacia's response to mercury contamination is not well understood.
- A study used transcriptome and metabolome analyses to explore how iron influences the plant's ability to remove divalent mercury (Hg2+) from contaminated soil.
- Results indicated that adding iron enhanced root plaque development, reduced harmful organic acid secretion, improved plant resilience to mercury, and ultimately supported better growth and mercury accumulation in aboveground tissues, highlighting iron's potential for aiding phytoremediation efforts.
