Abstract
Li et al. reviewed existing evidence to identify the mechanisms of by which common air pollutants 15 (PM2.5) induce brain damage. PM2.5 refers to the fine particles in polluted air with a diameter of 2.5 16 micrometres or smaller. These fine particles can enter the bloodstream and damage the brain via 17 various actions, including cerebrovascular damage, brain nerve damage and brain tumour formation. buprenorphine exposure, will continue to give essential information about the influence of 85 buprenorphine on neural circuits involved in psychiatric illness. 86The articles published in this Research Topic highlight cigarette smoking, maternal cigarette smoking, 87 opioids use during pregnancy, and PM2.5 as environmental toxins contributing to the pathogenesis 88 and aetiology of brain dysfunction. These studies advance our understanding of the molecular 89 mechanisms involved in acute and long-term exposure to environmental toxins.
