Based on recommendations from information specialists in the field of health, agriculture and technology the following databases were chosen to search for scientific literature about the present study's purpose: Pubmed, Embase, SveMed, CAB abstracts (Centre for Agriculture and Biosciences International), Agris, DADS (Denmark's Technical University's Digital Library), Scopus and Ebsco. The key search terms for the literature search were: personal protective equipment, farmers, pesticides, developing countries and tropical climate. Synonyms for each of these search terms were identified by means of Gyldendals Dictionary and previous international literature. In Pubmed, SveMed, Embase, CAB abstracts and Agris the synonyms were applied to find subject headings which the main search was based on. However, in DADS, Scopus, Ebsco searches on subject headings was not an option and therefore the main search was based on the synonyms.
