ATMOSPHERIC POLLUTION
City of London (Various Powers) Act, 1954
Clean Air Act, 1956
During the year 904 visits were made in connection with observed smoke emissions, routine
boilerhouse inspections and the National Survey. Of these, 430 were carried out under the nuisance
section of the Clean Air Act, 1956, mainly in connection with the burning of debris on sites
where demolition is taking place and on building sites. The remaining visits were made as a
result of observed smoke emissions and complaints and the necessary following up re-inspections.
With regard to the contraventions of the City of London (Various Powers) Act, 1954 which
stipulates that "no smoke shall be emitted from any premises in the City" the investigations
showed that in many cases the smoke alarm equipment had not been effectively maintained or
that the settings had been wrongly adjusted and informal action on the part of the Corporation Staff
was sufficient to effect the necessary improvements.
Smoke nuisances from the burning of debris, particularly by demolition contractors, do give
cause for concern. Whilst the difficulties of contractors are appreciated, it must nevertheless
be pointed out that the people in charge of the site operations will require to prevent this nuisance
as the Corporation is amending its procedure in order that more rapid and efficient action can be
taken against offenders.
Measurement of Atmospheric Pollution
The measurement of atmospheric pollution has continued during 1968.
Daily readings are taken at the two volumetric stations to enable the concentration of sulphur
dioxide to be found, by the volumetric measurement of sulphuric acid which is produced when air
containing S02 is bubbled through a solution of Hydrogen Peroxide.
Air is drawn from the atmosphere, though a filter paper, thus collecting small smoke particles.
This produces a grey coloured stain which by its density can give the quantity of smoke in the
atmosphere.
