OREANDA-NEWS American scientists have found a connection between environmental pollution and an increase in the number of people with mental disorders. 

After analyzing the health data of more than 150 million residents of the United States and Denmark, experts at the University of Chicago found that in areas with poor air quality, the risk of developing bipolar disorder increases by 27%, depression - by 6%. 

A close relationship was also found between soil contamination and an increase in the number of patients with personality disorder. 

As it was noted in a study published in the journal PLoS Biology, particularly high risk indicators for mental disorders were found in those who lived in contaminated areas at an early age. So, people who grew up in areas with low air quality more often than others developed depression, personality disorder, and schizophrenia.
