ABSTRACT:
The present invention relates to measurements of contaminants in the soil and other organic or environmental materials, using a biologically relevant chemical analysis that will measure the amount of contaminants in a given sample that may be expected to be absorbed by a human being ingesting the contaminated soil. According to the present invention, environmental samples to be tested are added to a pre-prepared physiological composition of bile salts and lipids. They are thoroughly mixed and then the resulting mixture is separated e.g. by centrifugation. The supernatant is then analyzed for the presence of contaminants and these concentrations are compared to the level of contaminants in the untreated samples. It is important that the bile salts and lipids be thoroughly pre-mixed to form micelles.
