    Smoke Abatement The purpose of a survey of sulphur pollution is usually to detect changes which may take place in the amount of pollution emitted each month. The lead peroxide method is particularly suitable for this purpose, although it cannot be used to estimate the total monthly weight of sulphur dioxide emitted within any given area. The four lead peroxide instruments were in operation for only two months of the year, and it is not possible to draw any conclusion at this early stage. With fuller information available in 1951, it is hoped that more definite conclusions may be drawn as a result of the in- vestigation. During the year 23 half-hourly observations were taken of smoke emission from factory chimneys within the Borough. Four lead peroxide instruments were fixed towards the latter part of the year. The sites chosen were:— 1. In the grounds of “Grasmere,” Stockport Road. 2. On the roof of the Ambulance Station, Lord Street. 3. At Jubilee Dingle. 4. In the grounds of the Hartshead Hospital. These sites were carefully selected in order to cover the conditions in the area and to give readings in the industrial, semi- industrial, residential and rural parts of the Borough. The results to the end of the year were as follows:— INVESTIGATION OF ATMOSPHERIC POLLUTION ESTIMATION OF SULPHUR BY LEAH PEROXIDE METHOD Weight o( liarium Sulphnt< /My.
