In genetic epidemiology, an envirome the total set of environmental factors, both present and past, that affect the state, and in particular the disease state, of an organism.〔(【引用サイトリンク】url=http://www.genomicglossaries.com/content/omes.asp )〕 The study of the envirome and its effects is termed enviromics. The term was first coined in the field of psychiatric epidemiology by J.C. Anthony in 1995. More recently, use of the term has been extended to the cellular domain, where ''cell functional enviromics'' studies both the genome and envirome from a systems biology perspective. ==Envirome classification== While there can be both positive and negative effects of the envirome on the organism, negative effects are often emphasized in discussing disease. A typology of envirome health hazards suggested by McDowall is〔 * natural physico-chemical * man-made physico-chemical * biological/organic, natural or man-made * macrosocial * micro- or psychosocial. The time-scale of the envirome hazard is another possible dimension of classification; an envirome hazard are said to be a sudden change (such as a disaster), a rapid environmental change, or a slow change or a static situation.〔 In twin studies, envirome influences are often decomposed into shared environmental factors, common to both twins and non-shared environmental factors that differ between the twins. 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「Envirome」の詳細全文を読む スポンサード リンク
