What is the empirical formula for dimethylmercury?
(CH3)2Hg
Dimethylmercury | (CH3)2Hg – PubChem.
What is dimethylmercury composed of?
Their experiments show that dimethylmercury can be formed in the presence of iron sulfide particles, as well as other metal sulfide particles, via the reaction of two methylmercury molecules bound to the particle surface.
Is dimethylmercury the same as mercury?
Dimethylmercury belongs to a class of organic mercury compounds known as alkyl mercuries. It is used primarily in research. It is a colorless liquid described as having a weak, sweet odor. Dimethylmercury is readily absorbed through the skin.
Where can I find dimethylmercury?
Dimethylmercury is a volatile and highly toxic form of mercury (Hg)1. It appears to be ubiquitous in marine waters and has been found in deep hypoxic oceanic water, coastal sediments and upwelling waters and in the mixed layer of the Arctic ocean2,3,4,5,6.
What is the molar mass of dimethylmercury?
230.662 g/mol

Is dimethylmercury water soluble?
Dimethylmercury, a very toxic by-product of the chemical synthesis of MeHg (Nierenberg et al. 1998), also has a relatively low water solubility (1.0 g/L at 21° C). Due to its low water solubility, MeHg chloride is considered to be relatively lipid soluble.
How do you make methylmercury?
Methylmercury is formed from inorganic mercury by the action of microbes that live in aquatic systems including lakes, rivers, wetlands, sediments, soils and the open ocean. This methylmercury production has been primarily attributed to anaerobic bacteria in the sediment.
What happens if you touch dimethylmercury?
Highly toxic if absorbed through the skin, contacted by the eyes, swallowed, or inhaled. A neurotoxin that causes severe and irreversible health effects, including death, after skin exposure to very small amounts (<1mL).

What is methylmercury found in?
Methylmercury is a neurotoxic contaminant that bioaccumulates in marine food webs, and is therefore found in seafood. Most of the mercury found in marine food webs originated as anthropogenic emissions, and the path from emission sources to fish depends on many processes which will be affected by a changing climate.
