According to WHO Director, Department of Public Health, Environmental and Social Determinants of Health Dr Maria Neira; “The contributing factors to pollution are a reliance on using solid fuels for cooking, burning waste and traffic pollution from very old cars.”
This notwithstanding adds to the use of generators at homes and office places due to the epileptic power supply across Nigeria.
He also added that, “In Africa, unfortunately, the levels of pollution are increasing because of rapid economic development and industry without the right technology.”
On finding a solution to the challenge Neira, “We need to do an assessment of the sources of pollution at city level, also work on better planning of urban collective transport systems, and take very old cars out of service.”
