WebIt remains a research question what fraction of this reactive mercury is converted to toxic methylmercury through biogeochemical reactions and taken up by animals and plants. Other Pathways In addition to atmospheric pathways, mercury can be transported through river systems in their sediment loads, or in aqueous solution. WebHowever, reactive mercury was a narrowly constrained fraction of the total mercury, making up only 4-16% of the total, showing evidence of the importance of dissolved organic matter on mercury transport. In sediments, higher concentrations of mercury were also determined near industrial discharges.
