Carbon Monoxide at the "Woodward Dream Cruise - 2000" (cont.)

Dream Cruise, Saturday, August 19th:
(all measurements were made at a level of 6 ft., through the open sunroof of a 1998 Mercury Villager minivan. Air temperature was 68o F and wind conditions of a continuous slight breeze. VERY heavy traffic was moving 0-10 mph northbound, 0-20 mph southbound.

  • 3:48 p.m., north of 12 Mile Road, in northbound, 3rd lane, behind a red Pontiac GTO - CO conc. varied 19-40 ppm.

  • 3:55 p.m., north of 12 Mile Road, northbound near Webster, behind Ford F250 pick-up truck (late model) - CO conc. varied 10-15 ppm.

  • After 4 p.m., south of Coolidge, northbound, 4th lane, white Japanese-made "Nova" - CO conc. was max. at 27 ppm.

  • After 4 p.m., south of Coolidge, northbound, 3rd lane, red Pontiac TransAm with 60's Cadillac on the left - CO conc. was 13-46 ppm.

  • After 4 p.m., intersection at 13 Mile Road, stopped at red light and cars revving - CO conc. max. was 42 ppm.

  • After 4 p.m., just south of Normandy (13-1/2 Mile Road) - CO conc. max. was 17 ppm.

  • 4:15 p.m., turned left across boulevard to go southbound, in 3rd lane, north of Normandy, behind a yellow Pontiac LeMans - CO conc. was 36-57 ppm.

  • After 4:15 p.m., at Normandy, southbound, in 3rd lane, behind a black Camaro Z28 - CO conc. max. at 35 ppm.

  • 4:30 p.m., north of 13 Mile Road, southbound, in 3rd lane, behind a 1969 green Pontiac - CO conc. was max. at 41 ppm.

    Conclusion: Substantial levels of carbon monoxide were present along Woodward Avenue where spectators were standing and in the roadway, which spectators, drivers, and passengers inhaled. Many/most of the levels exceeded the outdoor CO threshold established by EPA more than 20 years ago. It is unknown how many "Dream Cruisers" experienced dull or severe headaches, nausea, upset stomach, etc. as the result of elevated levels of this gas being present.

    On a personal note, we very much enjoyed this 6th annual Dream Cruise. Tell us about your experiences and thoughts about CO and the "Dream Cruise".
