The number of substances emitted into the atmosphere is immense and growing, but some are particularly harmful to health and are subject to increased monitoring.
An air pollution expert with years of experience advising federal regulators describes how the Trump administration is speeding up reviews and reducing scientific input.
A study of the social cost of carbon emitted by the shrinking fleet of Texan coal plants suggests that closing more of them down would be good for the climate and public health.
