compounds: human exposure and its relevance to public health.
In contrast to inorganic species, organic mercury
is lipophilic and more readily crosses cellular membranes, but it may demethylate intracellularly to inorganic mercury (Clarkson and Magos 2006), which may ultimately be more immunotoxic.
The behavior of the accessions for the effect of three heavy metals on Active Mitotic Indices (AMIs) and Total Mitotic Anomalies (TMAs) were significantly different, while in about 98% accessions lead could not produce adverse effects on AMI, selenium could not do the same in about 38% and organic mercury
in about 48%.
Blood levels of total and organic mercury

In utero exposure to mercury in environmental accidents, especially organic mercury
, has been associated with brain damage and pediatric diagnoses such as cerebral palsy--but not autism.
143) It can detect metallic and inorganic mercury exposure, but because organic mercury

Grain treated with an organic mercury
fungicide was the source of contaminated bread.
Metallic mercury, the silver fluid once used in thermometers, can become more dangerous than organic mercury
when released into the ocean, he said.
Methylmercury, formed by the interaction between bacteria and mercury in the water, is the most common organic mercury
and is of interest because it can contaminate seafood, building up in the tissue of fish.
