A. A. HASSAN, G.A. RAHEEM AND R.O. AGUNBIADE

Abstract

The influence of continual refuse burning on the well-being of residents of Aba-Eku was investigated. Solid wastes at the dumpsite included rubber, paper, rags, metals, leather, paints, disused tyres and dye. Mean daily ambient temperatures of 24.9 + 0.17°C. at lbadan metropolis and 36 + 0.51°C at AbaEku showed a high statistical significant difference (t = 5.9, p<0.05). Thermal discomfort reported by the inhabitants included heat stress, body itching and increasing contact with vectors of infectious disease. However, people closer to the dumpsite were at greater risk than those farther away from the dumpsite but there was no incidence of heat related mortality. Anopheline and culicine larvae were encountered, with the culicine larvae showing a higher occurrence than the anopheline larva at various temperature ranges. A negative correlation (r = -0.77, p<0.05) between the mosquito larva and ambient temperature at the dumpsite was observed.
