Abstract

A method of measuring an average long-term concentration of a specified gas in a certain environment accurately in a simplified manner with a small inexpensive apparatus by leaving a test piece such as metal, ceramic or metal salt to stand in an ambient atmosphere for a given period of time and analyzing the gas adsorbed thereby. In particular, NOx, CO2, and SO2 can be selectively adsorbed by, respectively, a porous metal or ceramic (transition metal oxide), a porous ceramic (rare earth element oxide), and a specified chloride such as copper chloride or silver chloride. The invention also discloses a test kit containing the test piece put in a case, and a protective case, umbrella and forced draft unit for putting the kit to practical use.
