University of Iowa News Release


Oct. 26, 2007

Mosquito pesticide is topic of Oct. 30 lecture

Kathy Kuivila, a scientist with the U.S. Geological Survey (USGS), will discuss the use of the insecticide pyrethroid in a free public lecture, titled "Pyrethroids: A Potential Peril?" at 1 p.m. Tuesday, Oct. 30, in the Lucas Dodge Room of the Iowa Memorial Union on the University of Iowa campus.

The use of pyrethroids has increased in recent years in urban and agricultural areas to control West Nile virus and other mosquito-transmitted diseases. Pyrethroids are highly toxic to aquatic invertebrates and fish, especially coldwater fish such as salmon. Researchers today are detecting the compound more frequently in surface waters.

Kuivila will present methods to sample and analyze pyrethroids at environmentally relevant levels. She also will discuss processes for controlling the use and bioavailability of the insecticide in the environment, using examples from field and laboratory studies.

The free event is hosted by the UI Center for Health Effects of Environmental Contamination (CHEEC) and the USGS.
