Procedures are suggested that may help to resolve these problems. High levels of mercury can impair a child's physical and mental development, including motor skills, learning capacity and memory. WebAlthough the possibility of methylmercury poisoning the heart and blood vessel system, the reproductive system, and the immune system is continuously raised and discussed, and the carcinogenicity of methylmercury is also under discussion, a clear conclusion regarding the human health effects according to exposure level has not yet been drawn. Mercury interferes with many of these pathways, inactivating enzymes and grabbing on to essential nutrients. This causes havoc as both brain and body rely on metabolic consistency for normal functioning. Just imagine a country where the supply and distribution of raw materials has been sabotaged: the entire economy might swiftly be shut down. WebIf repeatedly eaten or applied to the skin over long period of time, some inorganic mercury compounds can cause effects similar to what is seen with long term mercury vapor If repeatedly eaten or applied to the skin over long period of time, some inorganic mercury compounds can cause effects similar to what is seen with long term mercury vapor exposure, including neurological disturbances, memory problems, skin rash, and kidney abnormalities.
