Documents from the Environmental Protection Agency (EPA) show that the review of chemicals sometimes excludes potential exposures from the air, ground, or water and focuses only on direct contact with the substance, The New York Times reports.

The agency can “better protect human health and the environment by focusing on those pathways that are likely to represent the greatest areas of concern to E.P.A.,” Jahan Wilcox, an agency spokesperson, tells The Times.

Critics, including three former EPA officials, are skeptical of the new approach and say the resulting analyses of chemical threats would be incomplete. “It is ridiculous,” Wendy Cleland-Hamnett, who worked at EPA for nearly 40 years and led the toxic chemical unit before retiring, tells The Times. “You can’t determine if there is an unreasonable risk without doing a comprehensive risk evaluation.”

The less-extensive risk tests run counter to a law passed in June 2016 by then-President Barack Obama that required EPA to review the safety of hundreds of substances—including ...
