According to a recent study published by Stanford University and the University of California, San Diego in the United States, it has been discovered that, air pollution is responsible for one in five infant deaths in Nigeria and other sub-Saharan African countries.

The research team looked at combined data from over 15 years on approximately 1 million births across 30 countries in the sub-Saharan Africa region and found that satellite-based measurements of particulate matter, which contributed to 20 percent of infant deaths.

Particulate matter is a mixture of small particles and liquid droplets in the air that, once inhaled, can cause damage to the heart and lungs.

Study co-author and assistant professor of Earth system science in the School of Earth, Energy & Environmental Sciences at Stanford Marshall Burke said ‘‘many wealthy countries have recently used legislation to clean up their air. We find that if countries in Africa could achieve reductions in particulate matter exposure similar to wealthy countries, the benefits to infant health could be larger than nearly all currently used health interventions, such as vaccinations or food and water supplements.”

The researchers said even small decreases in the amount of particulate matter in the air can lead to substantial decreases in infant deaths and finding cost-effective ways to improve the air should be a policy and research priority.

Africa’s air pollution problem has become a growing concern for international research organisations.

Last year, a study by the Organisation for Economic Co-operation and Development found that air pollution is responsible for more deaths in the sub-Saharan Africa region than malnutrition or dirty water.
