Abstract
RESULTS FROM A COMPREhensive air pollution study confirm what experts have long suspected: Emissions from petrochemical complexes in Houston are responsible for the extraordinarily high levels of ozone that occur there. I think it's about as clear-cut a case as you would ever find, says Lawrence I. Kleinman, an atmospheric chemist at Brookhaven National Laboratory. Kleinman and other Brookhaven scientists are among hundreds of researchers from more than 40 public and private institutions who took part in the Texas 2000 Air Quality Study (C&EN, Nov. 6,2000, page 32). Using specially equipped planes, the scientists collected air samples in Houston, Nashville, New York City, Philadelphia, and Phoenix. They measured concentrations of nitrogen oxides (NO x ) and volatile organic compounds (VOCs), two ozone precursors, as well as ozone itself and other species. From those data, they calculated the rate of ozone production { Geophys. Res. Lett ., 29,10.1029/2001GL014569 (2002)}. Most of Houston resembles the o...
