Recording of Atmospheric Pollution
Deposit guages and lead peroxide candles were stationed at three sites in the
Borough results from which are recorded monthly. Due to vandalism however, the equipment
at York Way Court (Site 2) had to be removed and recording ceased at the end of November
Volumetric apparatus is also installed at the Town Hall and the Treatment Centre,
Seven Sisters Road, N. 7. The concentration of smoke and sulphur dioxide in the atmosphere
are recorded daily. The findings are forwarded to the Warren Springs Laboratory for
collation and comparison with other Metropolitan Boroughs in order that an overall
picture may be obtained for the whole of London
A severe smog episode occurred during the evening of 4th December and persisted until
the morning of 7th December During this period, arrangements were made for atmospheric
pollution readings to be taken at shorter intervals than at the normal 24 hour periods
on the Department" s instruments, and similarly, increased readings were taken on the
recording instruments in the Borough by the London County Council and the Department of
Scientific and Industrial Research.
To summarise the results obtained from all the Recording Stations in the Borough
both pollution by smoke and also by sulphur dioxide were very considerably increased
The increases varied according to the day or night and also to some extent on the different
days of the smog period. Pollution tended to be higher from the early evening onwards and
in the morning due, almost certainly, to the banking up of domestic fires about these
times.
During the four days when smog was present both smoke and sulphur dioxide atmospheric
pollution figures increased up to 14 times above the average.
A summary of the recordings from the Borough Council sites is set out in the following
tables.
