Ghana: Particle Pollution and Health Risks

What the report says

Ghanaian Times, published via AllAfrica, ran an explainer on 28 October 2026 about particle pollution, also called particulate matter (PM), and the health risks tied to exposure. The article defines PM as a mix of tiny solid particles and liquid droplets in the air, ranging from larger coarse particles to much smaller fine and ultrafine particles. It notes that these pollutants can come from direct emissions such as construction, roads, smokestacks, fires and vehicle wear, as well as from chemical reactions in the atmosphere involving gases from power plants, industry and traffic.

The report says particle pollution is found both indoors and outdoors and can be present even when the air looks clean. It highlights that fine particles are especially concerning because they can travel deep into the lungs and, in some cases, enter the bloodstream. The piece also says pollution levels can build up near busy roads, urban centers and industrial sites, and can worsen during calm, stagnant weather or when smoke from wood stoves, fireplaces or wildfires is present.

In terms of health, the article points to evidence linking PM2.5 exposure with higher risks of respiratory, cardiovascular, metabolic, autoimmune and neurological disease, as well as cancer. It identifies groups at greater risk, including children, older adults, pregnant women, people with asthma or COPD, and those with heart disease, diabetes or obesity. The report also advises checking air-quality alerts and, when exposure cannot be avoided, using a properly fitted respirator such as an N95.
