Carbon monoxide (CO) produced by internal combustion engines is an indoor health hazard. High CO levels can occur during indoor sporting events--such as tractor pulls--that involve vehicles modified to achieve high horsepower. In January and March 1992 and January 1993, the Cincinnati Health Department evaluated CO levels during tractor pulls, monster-truck jumps, and a mud race event held in an indoor arena with a seating capacity of approximately 16,000 persons. This report summarizes findings from the evaluations.
内燃机产生的一氧化碳（CO）是一种室内健康危害物。在室内体育赛事期间，比如拖拉机拉力赛，当涉及到为实现高马力而改装的车辆时，就可能出现高浓度的一氧化碳。1992年1月、3月以及1993年1月，辛辛那提市卫生部门对在一个可容纳约16000人的室内场馆举行的拖拉机拉力赛、怪物卡车跳跃赛和泥浆赛期间的一氧化碳水平进行了评估。本报告总结了这些评估的结果。
