Computer Glitch May Change Findings (JOHN HEILPRIN, June 5, 2002, Associated Press)

Scientists revising a study of tiny pollution particles from diesel engines and power plants found a computer glitch that might mean less health risk than previously thought and could delay new federal rules.

Research by investigators at Johns Hopkins University's biostatistics department indicates the software used for the study of 90 large American cities was overestimating the rise in the typical mortality rate.

The study is just one of more than 100 the Environmental Protection Agency is examining as it prepares to issue regulations next year. But the software in question could be a problem because it is used by many of the studies, agency spokesman Joe Martyak, said Wednesday.
