NSSI rates were similar overall: Non-suicidal self-injury was reported by …
TL;DR: A 2026 study in Journal of Exposure Science & Environmental Epidemiology linked prenatal PM2.5 and non-freeway NOx exposure with newborn amino-acid metabolism pathways that also tracked autism spectrum disorder (ASD) diagnosis before age 5. Key Findings 100 newborn blood spots: Researchers analyzed 50 children later diagnosed with ASD and 50 matched controls from Kaiser …
