Air pollution linked to rising depression rates, study finds
Advertisement
A groundbreaking study published in Environmental Science and Ecotechnology has revealed a strong connection between long-term air pollution exposure and an increased risk of depression. The research, led by Harbin Medical University and Cranfield University, analyzed data from over 12,000 participants in the China Health and Retirement Longitudinal Study (CHARLS).
The study identifies sulfur dioxide (SO₂) as the most significant contributor to depression risk, with fine particulate matter (PM2.5) and carbon monoxide (CO) also linked to depressive symptoms. These pollutants were found to have a compounded impact when combined, highlighting the dangers of multi-pollutant exposure.
