There was a story on the CNN news last night about Zamboni pollution. The
reporter was Joan McFarlane. She stated that in July 1993 50 students were
overcome by carbon monoxide fumes from a Zamboni. Levels of carbon monoxide
found were 10 times higher than federal guidelines. The problem results from
operating a combustible engine in an enclosed area.
 
The University of Michigan conducted a study where they measured carbon
monoxide levels before and after the Zamboni was used. Levels rose from
2 parts per million to 76 parts per million. Also it was found that in
Detroit two thirds of the ice arenas had high carbon monoxide levels.
 
In the Joe Louis Arena they replenish the air 100% every 4 minutes.
