Investigation of Atmospheric Pollution
Haringey continued to co-operate with the Department of Trade and Industry to which the Warren Spring
Laboratory is attached by operating four instruments at suitable sites in the Borough for recording the daily level
of smoke and sulphur dioxide in the atmosphere. In addition to giving information on local trends, the data
forms part of information collected by the Laboratory to show national distribution and trends in atmospheric
pollution. The readings obtained depend to some extent on varying local meteorological conditions which at times
may give rise to deviations from the general trend.
