Some ten years ago, at the instance of the late Mr. James Gray, then chairman of the Health Committee of the Johannesburg City Council, an advisory committee of experts was convened to study the position in regard to atmospheric pollution in the city. As a result of their deliberations, the Council put forward suggestions for strengthening the legal powers to deal with air pollution, and officials of the City Health Department intensified their efforts to improve matters within the scope of the existing legislation.
