Scope

This standard specifies a method of testing the bioaccessibility of substances in contaminated soil material and materials that may be applied to the soil or introduced into it (see article 6 of the Bundesbodenschutz- gesetz. It permits only those substances to be examined that have a sufficiently low vapour pressure and are not subject to appreciable loss under the test conditions set out below, Furthermore, suitable analytical methods may need to be used to detect the substances or elements inthe complex digestive solutions. In the system described here, the mobilization of organic and inorganic contaminants from contaminated material with the aid of synthetic digestive juices (gastric juice and intestinal juice and, in some cases, also saliva) is examined under standardized, physiologically realistic conditions. With regard to their main constituents, the composition of these solutions is very similar to the average composition of human digestive juices when their secretion is stimulated during the ingestion of food, The samples are treated with gastric juice for two hours, which is similar to the average time food is retained in the stomach. Following that, the samples are treated with intestinal juice for six hours, which represents the maximum time for which food components are retained in the small intestine as a whole.
