Researcher Joanne Newbury of King's College London looked at children born and raised in cities with high pollution, which were twice as likely to be psychologically ill compared to large children in the village.
In a study published in the journal JAMA Psychiatry involving data from more than 2,000 participants, Joanne mentioned the specifics if large children in the city were 94 percent more at risk of developing psychosis. Nitrogen oxides, nitrogen dioxide, and 2.5 particulate matter become the pollution that is seen as the most influential.
"The risk will be higher when you move from the environment to setting the village to the city environment," Joanne said as quoted by CNN on Thursday (03/28/2019).
Joanne stressed that her study only confirmed the relationship did not determine the causal effect.
Another researcher, Helen Fisher, argues that air pollution might increase the incidence of psychosis because exposure to pollution can cause inflammation in the brain as previous studies have shown. Coupled with noise pollution that is not less high in urban areas can also worsen the situation.
"Maybe this could also be due to noise pollution," Helen added.
