The kind of mercury that accumulates to toxic levels in fish is called monomethylmercury, or simply methylmercury, because it has a methyl group, CH3, attached to the mercury atom. The problem is that we donât know where methylmercury comes from.
Acute mercury poisoning can be detected by measuring mercury levels in the blood; this test is usually done in a specialized laboratory. A normal mercury level is less than 10 Âµg/L (micrograms/liter) and less than 20Âµg/L in urine.Higher levels suggest toxic exposure.his makes the diagnosis difficult for the physician because many times the symptoms of mercury poisoning are subtle and may take weeks, months, or years to develop in some individuals.
