It is often referred to as simply thallium sulfate. Thallium(I) sulfate is colourless, odourless, tasteless, and highly toxic. ==Uses== During the last two centuries, Tl2SO4 had been used for various medical treatments but was abandoned. In the later 1900s it found use mainly for rodenticides.〔(World Health Organization Pesticide Data Sheet no.10 (1975) )〕 These applications were prohibited in 1975 in the US due to the nonselective nature of its toxicity. Thallium(I) sulfate inhibits the growth of plants by preventing germination. Tl2SO4 is mostly used today as a source of Tl+ in the research laboratory. It is a precursor to thallium(I) sulfide (Tl2S), which exhibits high electrical conductivity when exposed to infrared light. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thallium(I) sulfate」の詳細全文を読む スポンサード リンク
