UCI chemistry professor Donald Blake will receive the 2013 National Award for Creative Advances in Environmental Science & Technology from the American Chemical Society. “This award reflects the collaborative efforts of the Rowland-Blake Group to advance the understanding of trace gases in the atmosphere,” Blake said. “I built many of the original analytical tools, and now the group has advanced those tools to be more accurate and precise.” Over the last three decades, Blake’s air samples have shed light on the quantification of greenhouse gases, gases affecting stratospheric ozone levels, and those causing urban smog formation. The award will be presented next spring at the 2013 ACS meeting in New Orleans.
