Mercury and methylmercury accumulation and excretion in prairie voles (Microtus ochrogaster) receiving chronic doses of methylmercury.

abstract：:Eighteen lichens from a variety of habitats were treated with 4-chlorobiphenyl (4-CB). All, as determined by means of radioactive tracers, were shown to partially convert 4-CB to 4-chloro-4'-hydroxybiphenyl. Only one species (Pseudocyphellaria crocata) produced a further major metabolite not previously reported, namel...
