Air pollution is a matter of concern everywhere, but at high altitudes it may have more significance because of the difficulty that some people have breathing rarefied air. Much of the construction in Western states is above the 6,000 foot level, and highways have been constructed above the 14,000 foot level. The results of tests for carbon monoxide, hydrocarbons, nitrogen oxides and particulates at construction sites in Colorado are presented in this report.
