In response to the need for finding chemical information we have set up a system to identify and access appropriate data-sources. This Information System for Environmental Chemicals consists of the following meta-databanks: DAMA: Databank of Manual Sources DADB: Databank of Databases DACD: Databank of CD-ROMs Data fields of theDatabank of Databases (DADB) will be explained in detail. Online databases of 12 international hosts including two Russian hosts and CD-ROMs (offline databases) are evaluated and compared according to some chemical-relevant parameters like identification, production and use, detection in the environment, physical-chemical properties, environmental transport and fate, ecotoxicity, mammalian toxicity and genotoxicity.
