This paper investigates the distribution of three common air pollutants, sulphur dioxide, nitrogen dioxide and ®ne particulates (PM 10 ), in England and Wales with respect to social class, ethnicity and population density. A multilevel model is used to demonstrate regional differences in the social distribution of pollution. The results show that, allowing for ethnicity and population density, there are different relationships between socioeconomic status and exposure to air pollution within different regions in England and Wales. These differences suggest that national legislation introduced to reduce air pollution levels may give rise to environmental injustice, with geographical and social differences in the costs and bene®ts arising to the population due to such legislation.

WHEN preparing my lecture on ozone during t'he recent term, it seemed advisable to ascertain if this body is really produced during the slow oxidation of phosphorus in moist air, as some doubts have lately becn thrown on its formation by this process. The experiments extended to an unforeseen length, and i t may be well to give a short account of them, although it is necessary to apologise for bringing merely qualitative experiments under the notice of the Society. The active substance formed during the slow oxidation of phosphorus is probably either ozone or peroxide of hydrogen ; the direction the experiments took, therefore, was to decide which of these bodies was present in the air in which phosphorus was nndergoing oxidation.
