[Methylmercury toxicity in insect: detection of mercury in lysosomes using electron microprobe].
Intoxication of Blattella by methylmercury leads to a storage of the ingested metal within the lysosomes of ileum. Mercury is always found associated with zinc, sulphur and copper. Lysosome, therefore, intervenes in a detoxication process in Insects which have been exposed to organic mercury. It is suggested that mercury might be trapped by metallothionein.
