| Abstract | This paper describes the method used for measuring the relative "activity" of sulphur dioxide at Canadian exposure sites and reports the values obtained over a period of three years. The lead peroxide method was used and factors affecting its variability and correlation with volumetric measurements were investigated in details at one of the sites. It is concluded that the lead peroxide method is particularly well suited for use in exposure studies at outdoor exposure sites. The different methods used for measuring atmospheric chlorides are discussed, the most promising being a modification of the "wet candle" method and use of rainfall cans. The chloride levels obtained during 1956 at a number of locations in the Halifax area are given. In addition brief reference is made to the performance of two standard metals which have been exposed at each of the sites to provide a measure of the relative corrosivity of the atmosphere. The eight outdoor sites described are used by the Associate Committee on Corrosion Research and Prevention for their outdoor corrosion studies. |
