Methylmercury
Methyl mercury, monomethylmercury, MeHg; formula: CH3Hg+X-; CAS Registry Number: 22967-92-6
Organometallic compound that is naturally formed from inorganic mercury ions
Most frequently microorganisms in sediments and soils are involved in the methylation. Burning of wastes and fossil fuels may also lead to MeHg emissions.
Environmentally relevant data for methylmercury are:
- very high toxicity to humans and animals
- carcinogenicity
- effects on reproduction and development demonstrated in animal experiments
- possibly endocrine disrupting activity
- very high bioaccumulation potential
- very high biomagnification potential
For more information about the for chemical analysis see the Guidelines for Chemical Analysis: Quantification of Methyl Mercury Compounds in Environmental Samples by ICP-MS.
