Description
Summary:This paper provides an overview of the emergent public health risks attributable to air pollution in Lagos and solutions to reduce them. Growing evidence has substantiated a causal relationship between air pollution and mortality, hospital admissions for respiratory or cardiovascular disease and an associated increased risk of myocardial infarction. Lagos, the former capital of Nigeria with a population of 15 million has been identified as one of the fastest growing megacities with annual mean concentrations many times higher than the thresholds recommended by the WHO. Given the urban conglomeration of Lagos, this paper shows that differential traffic density, socio-economic conditions, access to healthcare and proximity to sources of emissions create differential susceptibility of communities to ill health attributable to air pollution, especially within vulnerable groups including children, the elderly and pregnant women. The paper therefore argues that an understanding of the scale and spatial variation of air pollution is not sufficient for reducing the risks posed to public health. An effects-based approach needs to be adopted in order to frame air pollution problems in the city within a public health context, rather than as an environmental nuisance.
