The U.S. has seen improvements in reducing the public health consequences of air pollutants like nitrogen dioxide and fine particulate matter. However, these improvements have not been distributed equally among different racial and ethnic groups. While overall deaths and disease linked to air pollution have decreased, racial disparities have increased, particularly in pediatric asthma cases. The study suggests that more local regulation of emissions and pollution could help address these issues. There is a need for interventions that consider the historical impact of air pollution on disadvantaged communities and target solutions based on specific geographic locations to reduce disparities in health outcomes.
