Abstract
ATMOSPHERIC pollution in Greater London is usually associated with high concentrations of smoke and sulphur dioxide, but continual changes in human activity can lead to other types of pollution. One example is the reported occurrence of elevated ozone concentrations indicative of photochemical activity1. I present details of the spatial and temporal variation of ozone concentrations experienced in Greater London during the summer of 1975. The data are presented, in part, with reference to the Greater London Council (GLC) guideline concentration for ozone of 0.08 p.p.m. (1-h average)2,3. Observations indicate that photochemical ozone in and around London is likely to have a dual origin, namely, the European continent (see ref. 4), and photochemical reactions involving locally emitted precursor pollutants.
