Proposed Tighter Air Particle Standards by EPA Questioned

摘要

A debate over air pollution is heating up in the U.S. Senate as the EPA prepares to issue new ambient air standards for fine particles. The Senate Environment and Public Works Committee last week heard testimony from health specialists and atmospheric scientists, including some of EPA's own advisors, most of whom recommended that the agency tighten the annual and hourly maximum fine particle concentrations, a move that industry opposes.
