Is the serious ambient air pollution associated with increased admissions for schizophrenia?

Highlights: • This was the first study to explore the relationship between NO₂, PM₁₀, SO₂ and schizophrenic admissions by using DLNM. • NO₂, PM₁₀ and SO₂ may increase the schizophrenic admissions. • NO₂ and PM₁₀ on schizophrenia presented a short-term effect, while SO₂ has longer effects. • For high air pollution concentrations, male, 20-59 ages people, farmer and worker may be vulnerable people. Much of the research has shown an increased risk of psychiatric disorders in association with elevated exposure to air pollution, such as NO₂, PM₁₀ and SO₂. However, few studies investigate the effect of these air pollution on the risk of schizophrenia admissions and the lagged effect among different subgroups.
