Identification of environmentally relevant chemicals in bibliographic databases: a comparative analysis

    Research output: Contribution to journalJournal articleResearchpeer-review


    Valid and reliable information on the use and effects of chemicals is a key factor in the industry and not least within many regulatory agencies. Identification data from lists of substances sometimes leads to incomplete bibliographic analysis in the major chemical databases. The present study takes as its starting point environmentally important chemicals and the retrieval of selectively chosen substances in the four databases: SciFinder, Web of Science (WoS), Scopus and Google Scholar. The way chemical data are stored in the databases plays a major role in the recovery process but differences in coverage, sometimes major, are still found. No single database records all publications about a substance. Inspection of individual titles is necessary when performing a complete count of references. Special care is taken in order to make data from the different databases comparable using the same journals and time periods (2000-2009). A number of nomenclature as well as problems related to the chemical structure and function, often inherent in quantitative or qualitative bibliographic studies of chemicals, are discussed. The practical implications for registration of chemicals in different databases are demonstrated.
