UTAB - A COMPUTER DATABASE ON RESIDUES OF XENOBIOTIC ORGANIC-CHEMICALS AND HEAVY-METALS IN PLANTS

The UTAB Database contains information concerned with the uptake/accum ulation, translocation, adhesion, and biotransformation of both xenobi otic organic chemicals and heavy metals by vascular plants. UTAB can b e used to estimate the accumulation of chemicals in vegetation and the ir subsequent movement through the food chain. The database contains a ctual data from papers in the published literature dating from 1926 fo r organic chemicals and from 1976 for heavy metals. At present the dat abase is comprised of more than 37 000 records pertaining to 900 diffe rent organic chemicals, 21 heavy metals, and over 350 plant species. E ach record contains information on a single combination of species, ch emical, and dose. Other information includes the application and desti nation sites, amount accumulated, rates of uptake or translocation, pr oducts and sites of biotransformation, experimental condition paramete rs, and the source paper. Thus, the database can be used to quickly ob tain specific data pertaining to a chemical, plant species, mine spoil , etc. or it can be used for the comparative analysis of a set of data pertaining to groups of chemicals and plants.
