SMOKE AND ATMOSPHERIC POLLUTION.
Twenty-six complaints of smoke nuisance or annoyance from chimneys were dealt with
during the year, and in connection with these 208 observations were made. Many of the
offences were of a temporary character and did not recur. There has been no occasion to
take further action.
A critical examination of the air in the City was commenced in the year 1914, in conjunction
with the Committee for the Investigation of Atmospheric Pollution, appointed by
the International Exhibition and Conference in London, 1912. A large rain gauge is mounted
upon the roof of one of the Corporation's buildings in Golden Lane, and the rain-water from
a known area of surface is collected monthly. This rain-water, containing the soot, grit, and
dust washed from the air, has been submitted for examination to the Public Analyst and the
results tabulated. For comparison, the results obtained from similar observations made at
the Meteorological Office, South Kensington, on the west, and Victoria Park, on the east
of the rain gauge at Golden Lane, are shown in the attached table.
The table also shows the rainfall for the months of January to December of the year
1933, and the amounts found of insoluble matter, tar, soot, and dust, also the soluble matter,
together with the sulphates, ammonia and chlorine in the volume collected.
The results as given by the Public Analyst have been re-calculated into metric tons per
square kilometre during each month.
In addition to the foregoing, a daily observation has been made at mid-day at the Guildhall
of the purity of the air by a modern dry method, by which the suspended matter can
be readily demonstrated.
