Recent studies demonstrate a short 3–6-month atmospheric lifetime for mercury (Hg). This implies Hg emissions are predominantly deposited within the same hemisphere in which they are emitted, thus placing increasing importance on considering Hg sou

Total mercury (TotHg) and methylmercury (MeHg) concentrations were determined in various environmental compartments collected from water resources of three Water Management Areas (WMAs) - viz. Olifants, Upper Vaal and Inkomati WMAs, potentially impac

Inorganic mercury ions (Hg2+) in laboratory prepared solutions were determined with a screen-printed carbon electrode (SPCE) coated with a polyaniline-methylene blue (PANI-MB) polymer layer. The structure and properties of the PANI-MB polymer layer w

Recent studies suggest an increase in mercury (Hg) emissions to the global environment, particularly as a result of anthropogenic activities. This has prompted many countries to complete Hg emission inventories, based on country-specific Hg sources.

This paper provides an up-to-date assessment of global mercury emissions from anthropogenic and natural sources. On an annual basis, natural sources account for 5207 Mg of mercury released to the global atmosphere, including the contribution from re-

In this work, monomer solutions of aniline (ANI) and 2,2′-dithiodianiline (DTDA), an aniline derivative containing –S–S– links, were prepared and used in the electrochemical copolymerisation of ANI and DTDA by cyclic voltammetry on a screen-p

South Africa is regarded as a country with the 2nd highest mercury (Hg) emissions in the world. This assumption is based on estimates of total Hg emissions derived primarily from gold mining and coal combustion. The potential sources of Hg to the Sou

The bioavailability of ingested methylmercury (CH3Hg(III) was investigated in vitro using the gastric and intestinal fluids of channel catfish, Ictalurus punctatus, and Atlantic sturgeon, Acipenser oxyrinchus. Gastric fluid collected from each specie

The excised intestines of channel catfish, Ictalurus punctatus, were perfused at 20 or 4 degrees C for 1 h 45 min, with methylmercury (CH(3)HgCl) alone, or in the presence of excess L-cysteine (L-Cys), D-cysteine (D-Cys), L-methionine (L-Met); or wit

Methylmercury (CH3Hg(II)) was measured in various tissues and whole body of sheepshead minnows, Cyprinodon variegatus, following exposure to 100 ng/L methylmercury chloride (CH3HgCl) alone or in combination with one of the organic compounds cysteine
