Air pollution in the Christchurch metropolitan district
- Department of Health, Christchurch
A brief outline of the history of air pollution measurements in Christchurch is given with an outline of the factors which influence them, such as climate, fuels used, topography, etc. A short discussion on the D.S.I.R. survey and other more recent work follows.
From the present data, it seems that sulphur dioxide levels have remained relatively constant and smoke in the central city area has decreased, whereas in the residential areas it has remained relatively constant. Levels in the months of June and July are now far removed from those in London.
