Zusammenfassung:	It is intended to provide a convenient and less expensive assay method by which the presence or content of a chemical in an environmental sample can be determined without resorting to such an expensive assay device as in the fluorometry. More particularly speaking, an assay method characterized in that use is made of a recombinant cell which has been transformed by operably linking a polynucleotide encoding an oxidoreductase to the downstream of a promoter gene employed for monitoring which shows a change in the promoter activity in response to the chemical.
