She died of You do not have permission to view the full content of this post. Log in or register now. at the age of 48 due to accidental exposure to the organic You do not have permission to view the full content of this post. Log in or register now. compound You do not have permission to view the full content of this post. Log in or register now. (Hg(CH3)2). Protective gloves in use at the time of the incident provided insufficient protection, and exposure to only a few drops of the chemical absorbed through the gloves proved to be fatal after less than a year.

Dimethylmercury is extremely toxic and dangerous to handle. Absorption of doses as low as 0.1 You do not have permission to view the full content of this post.

Permeation tests showed that several types of disposable latex or polyvinyl chloride gloves (typically, about 0.1 mm thick), commonly used in most You do not have permission to view the full content of this post.

The toxicity of dimethylmercury was highlighted with the death of You do not have permission to view the full content of this post.
