Researchers 'sniff out' emissions from feedyards

Setting up an air quality trailer in the midst of cattlepens at a feedlot will help measure gaseous emissions, said a TexasAgricultural Experiment Station researcher. Dr. Ken Casey, Experiment Station air quality engineer in Amarillo,wants to measure ammonia and hydrogen sulfide emissions from feedyards. His research team is setting up two climate-controlled instrumenttrailers in different locations at a feedyard. The trailers will beequipped with two continuous emissions analyzers.

10. Higher levels of pollutants found in fish caught near a coal-fired power plant
    11-07-2007 · EurekAlert!
    Emissions from coal-fired power plants may be an important source of water pollution and fish contamination, say researchers at the University of Pittsburgh. Researchers found higher-than-EPA-recommended levels of mercury and elevated levels of selenium in channel catfish caught in a rural area downwind from a coal-fired power plant. Based on testing of 63 fish, they found that fish caught near the power plant had 19 times more mercury than store-bought fish.
