ATMOSPHERIC POLLUTION AND CLEAN AIR
During the year, a sixth Smoke Control Order was confirmed by
the Minister of Housing and Local Government and at the date of
writing, a seventh Order made by the Council had been submitted
to the Minister for his approval. The preliminary survey of Area 8
is nearing completion.
A map of the Borough showing areas covered by Smoke Control
Orders and areas in which it is proposed to make Orders in future
years, incorporated in this Annual Report for the past three years,
is again reproduced in the following pages.
Measurement of Atmospheric Pollution
Daily readings of the concentration of smoke and sulphur dioxide
(SO2) in the atmosphere were continued during the year at the five
stations in different parts of the Borough where recording apparatus
has been set up, and as in the previous year, a record of these
readings for the year under review is given in Table I. Recordings
at Queen Mary's Hospital, Roehampton, were suspended for a
period of six months, whilst the premises were under repair.
A comparison of smoke and SO2 concentration for the past two
years is shown in Table II.
