U-M environmental scientist Joel Blum wins 2013 Patterson Award for research on mercury
Date:2/14/2013

ANN ARBORUniversity of Michigan environmental scientist Joel D. Blum has been awarded the 2013 Clair C. Patterson Award from the Geochemical Society for the development and application of innovative techniques that have enhanced the understanding of the behavior of mercury in the environment.

The Patterson Award is given annually for a breakthrough of fundamental significance in the field of environmental geochemistry. It is the Geochemical Society's highest honor in the discipline of environmental geochemistry.

Blum is the Arthur F. Thurnau and John D. MacArthur Professor of Earth and Environmental Sciences and a professor in the Department of Ecology and Evolutionary Biology. His research group developed methods to make high-precision measurements of mercury isotope ratios and has applied this tool to a wide range of research problems in biogeochemistry and environmental science.

The techniques have been used, for example, to obtain the first-ever chemical "fingerprints" of the element mercury in the environment, enabling researchers to directly link exposure in animals and humans to specific sources of pollution.

Mercury is a naturally occurring element, but more than 2,000 tons are emitted to the atmosphere each year from human-generated sources such as coal-fired power plants, small-scale gold-mining operations, metals and cement production, incineration and caustic soda production. Health effects on humans include damage to the central nervous system, the heart and the immune system. The developing brains of fetuses and young children are especially vulnerable.

The Patterson Award is named for Clair Cameron Patterson, who is known for two major scientific accomplishments. Using lead and uranium isotope measurements from the Canyon Diablo meteorite, he calculated the age of the Earth to be 4.55 billion yearsa figure far more accurate than those that existed at the time and one that has remained unchanged for mor
