In a recent study published in JAMA Network Open , researchers examined the impact of prenatal and early life exposure to noise and air pollution on mental health outcomes, specifically depression, anxiety, and psychotic experiences, in individuals aged 13 to 24. The findings revealed that increased exposure to fine particulate matter (PM2.5) during gestation and childhood is associated with higher rates of depression and psychotic experiences.
Furthermore, higher levels of noise pollution during childhood and adolescence were linked to increased anxiety levels. This study underscores the significant impact of early life pollution exposure on young people's mental health.

Previous studies have suggested a link between air pollution and psychiatric problems, including mood, affective, and psychotic disorders, through mechanisms such as neuroinflammation and oxidative stress.
Despite this, significant research gaps remain, particularly regarding the impact of exposure during early life, including prenatal periods, on mental health. Additionally, few studies have explored the relationship between air pollution .
