A Systematic Review and Meta-Analysis of Multiple Airborne Pollutants and Autism Spectrum Disorder

We conducted a systematic review of the human evidence on the relationship between ASD and exposure to all airborne pollutants, including particulate matter air pollutants and others (e.g. pesticides and metals).
