Atmospheric Pollution
Investigation into the atmospheric pollution in the City was continued
during the year at three sites, Mayfair, Pimlico and Charing Cross,
where deposit gauges, which measure the deposited pollution, and lead
peroxide cylinders, which measure the sulphur activity, are sited. The
following table gives the results of the monthly analyses, and shows
separately the amounts of insoluble and soluble constituents.
