ATMOSPHERIC POLLUTION RECORDING
The Council maintains two measurement and recording stations. The
readings are submitted to the Department of Scientific and Industrial Research,
who issue monthly bulletins indicating the national picture as regards
atmospheric pollution.
The stations are situated at the Chelsea Polytechnic, Manresa Road,
and the Chenil Galleries, King's Road.
Chelsea Polytechnic
The apparatus situated on this station consists of a deposit gauge
for collecting the amount of soluble and insoluble deposits, and a lead
peroxide apparatus for measuring the sulphur content of the air. The
deposited matter is collected at the end of each month and forwarded to
The Royal Institute of Public Health and Hygiene for analysis.
The following tables show the results obtained from this station during the years:-
