Chemistry in Indoor Environments: 20 Years of Research Supporting Information This “Supporting Information” categorizes studies that are indirectly related to indoor chemistry. These include Tables listing papers that address: S1) analytical methods intended for use in indoor chemistry studies; S2) ozone production from ozone generators, ion generators, and photocopiers; S3) deposition velocities and/or rate constants for ozone removal in rooms and to the surfaces of various building products; S4) passive removal of indoor pollutants via reactions on the surfaces of catalytic paints and ceiling tiles, or sorption to carbon cloths and special fabrics; and S5) the influence of humidity on emissions from polyvinyl chloride (PVC) and latex paint. Also listed in Table S6 are three editorials related to chemistry in indoor environments. I have chosen to not include studies of ultraviolet/photocatalytic (UV/PCO) air cleaners. Although such devices are related to catalytic paints and ceiling tiles that are used for passive pollutant removal, UV/PCO devices are active air cleaners and, as such, are a further step removed from the central focus of this review. They also have an already extensive literature of their own.
