US air pollution monitoring network has gaps in coverage, say researchers

The lack of air-quality monitoring capabilities across the U.S. affects the health of millions of people and disproportionately impacts minority and low socioeconomic-status communities, say researchers. Motivated by a new U.S. Environmental Protection Agency (EPA) standard for air pollution, the team employed a model for fine-scale air pollution mapping using real-world data, and it indicates there is an urgent need to address gaps in the agency's monitoring network.
