They sometimes hold the formula HgR2, which might be generally unstable, or HgRX, which might be frequently solids, where R is aryl or alkyl and X is normally halide or acetate. Methylmercury, a generic term for compounds Along with the formula CH3HgX, can be a dangerous loved ones of compounds that in many cases are found in polluted h2o.[sixty five] They occur by a method known as biomethylation.
Unborn babies whose moms have substantial levels red mercury price per gram of mercury in their blood can be born with brain destruction and hearing and vision problems. Amounts of the toxic element is usually measured in samples of blood, hair, or urine.
