Although there are no legally enforceable standards for air quality in the UK, informal ‘air quality objectives’ are sometimes used. These include a set of objectives recommended by an Expert Committee of the World Health Organisation and the ‘acceptable’ ground level concentrations of pollutants that chimney heights are calculated to produce.
Enforceable air quality standards are used in some countries and may be adopted in the UK if current EEC proposals are accepted. However, the Royal Commission on Environmental Pollution has recommended the use of a flexible system of air quality guidelines as an alternative to the EEC proposals.
Whether or not they form part of a formal system of air pollution control, air quality objectives can be used as a quick and valuable guide to ‘acceptable’ concentrations of pollution. However, they should not be used without first checking what, if any, degree of nuisance or risk they may incorporate.
