Air pollution and mental health risks

According to the study, sulfur dioxide (SO₂) emerged as the top pollutant most strongly linked to an increased risk of depression. Carbon monoxide (CO) and fine particulate matter (PM2.5) also played a role in raising the likelihood of developing mental health issues. The research further suggests that being exposed to a mix of these pollutants can significantly amplify the risk of depression.

The researchers explained that air pollutants might impact the central nervous system by triggering oxidative stress and inflammation. These effects could occur through various pathways, including the bloodstream, the trigeminal nerve, or even olfactory receptor neurons. However, they added that more research is needed to fully understand how air pollution contributes to mental health issues.
