Solid waste management and health hazards associated with residence around open dumpsites in heterogeneous urban settlements in Southwest Nigeria

The existence and multiplication of open dumpsites (ODs) around residential settlements are associated with environmental health outcomes in urbanizing settlements of developing countries. The study assessed existing practice and perceived health hazards of residence around ODs in Nigerian heterogeneous urban settlements. The cross-sectional, mixed-method study administered a validated questionnaire on 195 respondents using a 4-stage sampling technique. Two focus group discussions (FGDs) were conducted and analysed by ATLAS.ti software. Continuous and categorical variables were respectively presented by means and proportions; associations among variables were determined by chi-square and logistic regression at P alpha<0.05. Seventy-two per cent of the respondents disposed of solid waste in ODs, despite good knowledge (95%) and a positive attitude (85%) on perceived health-hazards. One-sixth (15%) of respondents were willing to pay for waste collection service and 50% considered burning as an alternative to open dumping. The most and least perceived health outcomes were malaria and breathing difficulties. Improved water sources and skin irritations were significant predictors of sound SWM practices.
