(from Dr. Peter Joseph, joseph@oasis.rad.upenn.edu) FALLACIES OF EXISTING INTERPRETATIONS OF DATA 1. Only MTBE is causing problems, not TBF or TBA; i.e. symptoms should correlate with blood [MTBE]. 2. No TBF is created in automobile exhaust. 3. Ambient TBF levels are too small to create problems. 4. People with MCS are most likely to suffer; or, all chemical sensitization is psychological. 5. Irritation symptoms are a "short term" effect. 6. TBF is no more irritating than ethyl formate. 7. Asthma increase is limited to minority people in cities. 8. Asthma increase is due to sub-micron particles. 9. Respiratory infections are not affected by TBF. 10. Cloudy days and sunshine are irrelevant.
