AIR POLLUTION
INDUSTRIAL AND COMMERCIAL CONTROL
The following are the number of notifications and applications received during the year in
respect of new furnace installations and chimneys:-
Clean Air Act 1956 - Section 3 (1)
Notifications of installation of furnaces (over 55,000 BTU's) 13
Clean Air Act 1956 - Section 3 (3)
Applications for prior approval of installation of furnaces (all approved) 6
Clean Air Act 1968 - Section 6
Applications for approval of chimney heights (all approved) 3
CONTRAVENTION OF A SMOKE CONTROL ORDER:
Reference was made in last year's report to a complaint of nuisance from smoke arising from the
burning of an unauthorised fuel, viz; wood off-cuts, on a coke heating stove in a factory in
Southgate Road. in spite of several warnings the nuisance continued and legal proceedings were
taken against the firm resulting in a fine of £10 and £5 costs for contravening a Smoke Control Order.
MEASUREMENT OF AIR POLLUTION:
The measurement of smoke and sulphur dioxide proceeded at the Department's three sites with
a fourth site being operated by the Medical Research Council Air Pollution Unit situated at St.
Bartholomew's Hospital Medical College in Charterhouse Square, London, EC1.
The combined average monthly pollution figures for the Borough's three sites are shown in the
form of two block graphs, comparison being made with the figures for 1972.
Surprisingly, several months of the year indicate higher pollution levels than those recorded in
1972 and the reasons for this could be complex and varied. As an example, the mean monthly
temperatures for April were below normal which undoubtedly led to an increase in the use of heating
appliances and in May patches of inland fog coincided with unsettled weather conditions generally.
