ATMOSPHERIC POLLUTION.
The Council is represented on the Thameside Advisory
Committee for the Abatement of Atmospheric Pollution. By
arrangement with this Committee a deposit gauge is installed
on the roof of the Education Office in Brampton Road,
Bexleyheath, and the following table gives the results obtained during 1963.
