EFSA residues public ver.3

The database contains 1281 metabolic maps and 9,477 metabolites for 177 unique parent chemicals. The collection includes unsubstituted aromatic chemicals, halides and multifunctional compounds - amines, acetals, ketals, (thio)carbamates, thio- and dithiophosphates, carboxylic acids, nitriles, (thio)esters; (thio)amides, phosphonic acid, carbonates, ketones, epoxides, ethers, ketoxime derivatives and sulfonamides. The variety of experimental conditions is represented through 8,500 treatment groups covering plant metabolism and in vivo metabolism in ruminants, fish and poultry. Plant studies (6,355 treatment groups) prevail over animal studies (2,145 treatment groups) and include various plants and rotational crops - alfalfa, apple, banana, barley, beans, bermudagrass, broccoli, cabbage, canola, carrot, celery, cherry, citrus, coffee, corn, cotton, cucumber, eggplant, grape, grapefruit, grass, kale, kiwi, lemon, lettuce, linseed, maize, mandarin, mustard, oilseed rape, olive, onion, orange, pea, peanuts, peach, pear, Persian clover, poppy, potato, radish, rapeseed, red beet, red bell pepper, rice, ryegrass, soybean, spinach, strawberry, sugar beet, sugarcane, sunflower, suiss chard, tangerine, tea plant, tobacco, tomato, turnip, wheat. The animal studies include ruminants (cow, goat), poultry (hen, chicken) and fish (rainbow trout, bluegill).

The database is built using MSS Composers and MetaPath software. The quantitative information and details about treatment groups and test conditions could be seen in the MetaPath platform.

The original EFSA residues public MTB database was extended by adding explicit links between metabolites quantities in various results tables and corresponding metabolites and treatment groups in attempt to improve the utilization of quantitative data for metabolites within OECD Toolbox. The effort was funded by European Chemicals Agency (ECHA) and was conducted by LMC.

Important note: Since its publication in 2023, EFSA put additional efforts in reviewing and fixing the content of the database. An improved and extended version of the same database (including 300+ new metabolic maps) will be available soon.
