Measurement of Atmospheric Pollution
The London Borough of Enfield was one of the participating authorities in the
National Survey of Air Pollution which was completed during 1968. The measurements
of smoke and sulphur dioxide have covered a period of six years and there
has been substantial reduction in the amounts of these pollutants in the atmosphere
over this period.
In the survey, four smoke filter and sulphur dioxide volumetric measuring
instruments were sited in selected areas of the borough and measurements taken
daily. The results were forwarded to the Fuel Research Station of the Ministry of
Technology at Stevenage.
Station 1 was sited at Honilands School, Bullsmoor Estate, Enfield.
Station 2 was sited at Stockingswater Lane, Brimsdown, Enfield.
Station 3 was sited at Merryhills School, Worlds End Lane, Enfield.
Station 4 was sited at Bush Hill Park Library, Fourth Avenue, Bush Hill
Park.
At the commencement of the survey, Station 1 was in a smoke control area; Station
2 in an industrial area; Station 3 in a residential area with a low population density;
and Station 4 in a residential area with a high population density. Stations 1, 3
and 4 are now in Smoke Control Areas.
In addition to the sites approved for the National Survey, three other sites were
in use until early 1968 at the following locations :
(a) Latymer Grammar School, Hazelbury Road, Edmonton, N.9.
(b) Huxley Secondary Modern School, Silver Street, Edmonton, N.18.
(c) Mandeville Secondary Modern School, Cuckoo Hall Lane, Edmonton, N.9.
The measurements obtained from these instruments were also sent to the Fuel
Research Station.
All the instruments have been withdrawn from these sites and have been relocated
in the area surrounding the new refuse disposal plant at Deephams,
Edmonton. This plant, one of the largest of its type in Europe, is expected to begin
operation in part in 1969, and to be in full operation in 1970. The plant
will emoloy the most modern equipment available for reducing atmospheric pollutants
and, although no difficulties are anticipated, the measuring instruments have been
sited to measure the level of pollution before and after the plant commences
operations.
During 1968 the infra-red gas analyser sited in Church Street, Enfield, continued
to check the level of carbon monoxide in this confined busy thoroughfare. The
