ABSTRACT: The distribution of 12 environmental contaminants or metabolites with diverse polarities (2,2',4,4',5-pentabromodiphenyl ether; bisphenol A; estrone; glyphosate; β-hexabromocyclododecane; imidacloprid; 2,3',4,4',5-pentachlorobiphenyl; 3'-methylsulfone 2,2',4,5,5'-pentachlorobiphenyl; 1,2,7,8-tetrachlorodibenzo-p-dioxin; 2-hydroxy-1,3,7,8-tetrachlorodibenzo-p-dioxin; tetrabromobisphenol A; and triclocarban) among skim milk, fat, curd, whey, whey retentate, and whey permeate was characterized. Analysis of these compounds along with 15 drugs previously studied provided a robust linear model predicting the distribution between skim and fat and the chemical's lipophilicity (log P, r 2 = 0.71; log D, r 2 = 0.79). Similarly, distribu
