It is a highly toxic emerald-green crystalline powder〔(【引用サイトリンク】title=Hazardous Substance Fact Sheet )〕 that has been used as a rodenticide and insecticide, and also as a pigment, despite its toxicity. It is also used as a blue colorant for fireworks.〔(【引用サイトリンク】title=How to Use Copper in Pyro Star Compositions to Create Blue Fireworks Stars )〕 The color of Paris green is said to range from a pale, but vivid, blue green when very finely ground, to a deeper true green when coarsely ground. ==Preparation== Paris green may be prepared by combining copper(II) acetate and arsenic trioxide.〔"H.Wayne Richardson, "Copper Compounds" in Ullmann's Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. 〕 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「Paris green」の詳細全文を読む スポンサード リンク
