Professor Kim Do-gwan at the Neuropsychiatry Center of Samsung Medical Center argued that PM-10 increases depression and raises suicide rates. A research team led by Kim analyzed the correlation between the air pollution index and suicide rate from 2006 to 2011 by region and discovered that increased levels of fine dust and ozone led to higher suicide rates.
According to the study, the suicide rate increased 3.2 percent whenever the concentration of fine dust particles (PM10) rose by 37.82㎍/㎥ per week. Similarly, the suicide rate rose 7.8 percent whenever the concentration of ozone rose by 0.016ppm per week.
The research team explained that air pollutants like PM-10 and ozone disturb neurotransmitters in the central nervous system and can also exacerbate diseases. Of particular note, ozone negatively impacts serotonin metabolism, and causes more suicides.
The study was sponsored by the Ministry of Health and Welfare, and was published in the latest issue of “Public Library of Science.”
