Lead is a ubiquitous and poisonous heavy metal. It is widely distributed in the environment (air, soil, sediment, surface and ground water, food, dust, paint) and in biological systems . It occurs both naturally and as a result of human activities . One of the most common sources of human exposure to lead is through exhaust from use of leaded petrol. However this practice is being discontinued worldwide  leaving the domestic environment (through house paint, potable water and dust) as the main continuing source of lead exposure in many communities around the world. While both adults and children can suffer from chronic low-dose lead exposure, the effect is more marked in children [2,4-6].
In Nigeria, like most developing countries, very little attention is currently paid to environmental health problems including chronic lead exposure . Yet these factors are responsible for more morbidity, disability-adjusted quality of life loss and mortality than in developed countries [7-9]. It was recently estimated that a reduction of the blood lead levels of children in the United States from 17.1 μg/dL to 2.0 μg/dL, in the period 1976 to 1999, resulted in public health benefits of $319 billion . The proportional impact of reducing childhood lead exposure in developing countries, where children's blood lead levels are likely to be higher, would be much greater. While many developing countries are currently making efforts to reduce exposure to lead by using lead-free petrol, very little is being done to address the more ubiquitous sources of exposure in the domestic environment . In this study, we conducted several focus group discussions with adult residents of Ibadan, a large metropolis in South Western Nigeria to evaluate their knowledge, attitudes and practices with respect to chronic low-dose domestic lead exposure and its effect on health.
