We examined the composition and spatial correlation of sulfur and mercury pools in peatland soil profiles by measuring sulfur speciation by 1s X-ray absorption near-edge structure spectrocopy and mercury concentrations by cold vapor atomic fluorescen

Passive air samplers (PASs), which provide time-averaged concentrations of gaseous mercury over the timescale of weeks to months, are promising for filling a gap in the monitoring of atmospheric mercury worldwide. Their usefulness will depend on thei

Mercury methylation and methylmercury demethylation in boreal lake sediment with legacy sulphate pollution

Autor: Haiyong Huang, Vaughn Mangal, Michael D. Rennie, Huan Tong, Myrna J. Simpson, Carl P. J. Mitchell

Publikováno v: Environmental science. Processesimpacts. 24(6)

Sulphate and dissolved organic matter (DOM) in freshwater systems may regulate the formation of methylmercury (MeHg), a potent neurotoxin that biomagnifies in aquatic ecosystems. While many boreal lakes continue to recover from decades of elevated at
