    Soil Geobacteraceae are the key predictors of neurotoxic methylmercury bioaccumulation in rice

    Contamination of rice by the potent neurotoxin methylmercury (MeHg) originates from microbe-mediated Hg methylation in soils. However, the high diversity of Hg methylating microorganisms in soils hinders the p...

    Tree foliage as a net accumulator of highly toxic methylmercury

    Tree canopies are known to elevate atmospheric inputs of both mercury (Hg) and methylmercury (MeHg). While foliar uptake of gaseous Hg is well documented, little is known regarding the temporal dynamics and or...

    Alteration of acute toxicity of inorganic and methyl mercury to Daphnia magna by dietary addition

    Acute toxicity of inorganic mercury [Hg(II)] and methylmercury (MeHg) to Daphnia magna was characterized using a 48-h static, non-renewal acute toxicity test, in which we compared the toxicity of Hg(II) and MeHg ...

    Elucidating Microbial Pathways of Mercury Methylation During Litter Decomposition

    Tree foliage sequesters gaseous elemental mercury (Hg) through stomatal uptake, when the foliage senesces and falls into the water, Hg from leaf litter can be released into the water and/or microbially methyla...
