PM2.5 stands for particulate matter 2.5 microns or smaller. These particles are 30 times thinner than a human hair and come from car exhaust, power plants, wildfires, and burning fuel. They are small enough to bypass your body's natural defenses and enter your bloodstream.

How does air pollution affect the body?

Air pollution affects virtually every organ in the body. PM2.5 particles enter your lungs, pass into your bloodstream, and travel to your heart, brain, kidneys, liver, and other organs. This causes chronic inflammation, increasing risks of heart disease, stroke, lung cancer, dementia, and many other conditions.

How many people are affected by air pollution?

99% of the global population breathes air that exceeds WHO safety guidelines. Air pollution kills approximately 8 million people every year—more than AIDS, malaria, and tuberculosis combined.

Overview

Air Pollution in Lualaba

Lualaba faces significant air pollution challenges. 100% of districts exceed the WHO guideline for clean air. This is putting 2.1 million across 7 districts at risk.

The average PM2.5 over 2023 was 32.7µg/m³. That's 6.5 times the WHO guideline for clean air of 5µg/m³.

This is equivalent of everybody, including children, smoking about 543 cigarettes in a year.
