Mercury exposures in surplus of dietary selenium intakes in younger children may have critical neurological penalties, blocking nerve sheaths from forming adequately.
Due to the fact the process of mercury-dependent sequestration of selenium is gradual, the time period in between publicity to methylmercury and the looks of signs and symptoms in Grownup poisoning situations tends to be prolonged. The longest recorded latent time period is 5 months immediately after an individual exposure, inside the Dartmouth circumstance (see Historical past); other latent periods from the number of months to months have also been noted.
Mercury takes place In a natural way in the earth's crust. It is actually unveiled into the natural environment from volcanic action, weathering of rocks and on account of human activity.
Methylmercury is particularly dangerous because it biomagnifies in food stuff chains. Therefore concentrations of methylmercury increase in the tissues of organisms at bigger trophic degrees.
