The<unk>  (T3DB), also known as the<unk>  Exposome<unk> , is a freely accessible online<unk>  of common substances that are<unk>  to humans, along with their protein, DNA or organ<unk> s. The<unk>  currently houses nearly 3,700<unk>  compounds or poisons described by nearly 42,000 synonyms. This list includes various groups of<unk> s, including common pollutants, pesticides, drugs, food<unk> s, household and industrial/workplace<unk> s, cigarette<unk> s, and uremic<unk> s. These<unk>  substances are linked to 2,086 corresponding protein/DNA<unk>  records. In total there are 42,433<unk>  substance-toxin<unk>  associations. Each<unk>  compound record (ToxCard) in T3DB contains nearly 100 data fields and holds information such as chemical properties and descriptors, mechanisms of action,<unk> ity or lethal dose values, molecular and cellular interactions, medical (symptom and treatment) information (Fig. 1-3), NMR an MS spectra, and up- and down-regulated genes. This information has been extracted from over 18,000 sources, which include other<unk> s, government documents, books, and scientific literature. The primary focus of the T3DB is on providing mechanisms of<unk> ity and identifying<unk>  proteins for common<unk>  substances. While a number of other<unk>  compound<unk> s do exist, their emphasis is on covering large numbers of chemical compounds that are almost never seen outside a chemical laboratory. T3DB attempts to capture data on only those<unk>  substances that are abundant or in widespread use and have been detected or measured in humans. T3DB is fully searchable and supports extensive text, sequence, chemical structure, relational query and spectral searches. It is both modelled after and closely linked to the Human Metabolome<unk>  (HMDB) and DrugBank. Potential applications of T3DB include metabolomics and environmental exposure studies,<unk>  compound metabolism prediction,<unk> /drug interaction prediction, and general<unk>  substance awareness.
