Abstract: In assessing the effect of indoor emission sources, such as furniture and building materials which emit hazardous chemical substances to indoor environment, with respect to chemical substances emitted from each emission source; calculating a emission amount (Qn) of each emission source per time using parameter of a emission rate (Fn) of chemical substances emitted from each emission source per area and per time and a surface area (Sn) of each emission source; with the result, calculating individually an indoor concentration of a specific chemical substance when assuming that only each emission source is individually placed indoors; and outputting the individual indoor concentration as the fundamental data.

Abstract: A passive type emission flux sampler measures an emission flux of a specified chemical sample released from an inspection object. The passive type emission flux sampler includes a hollow casing sealed except for an opening formed at a bottom for taking in a chemical substance. A test specimen that changes color in a reaction with the chemical substance is disposed to an inner surface of the casing opposite the opening. A water retaining material for maintaining the test specimen in a humid condition is disposed in the hollow casing.
