In a 1999 study, the cold cap above the ice was shown to trap nitrogen dioxide and carbon monoxide from a propane-powered Zamboni. An aerosol particle like COVID accumulates under the cold air inversion. This is the likely cause of the ice rink COVID infections. The CDC has identified hockey arenas as COVID spreading sites but has not identified the mechanism. Hockey players do not have sustained contact with each other. However, the rapid deep exhaling of emitters fill the cap space with huge amounts of COVID, and the other players rapid deep inhaling are consuming huge amounts of COVID
