title: Air pollution analysis used in operating an environmental control unit.
abstract: A simple, fast and reliable method was developed to measure the origin and daily and seasonal variations of selected air pollutants in the Brookhaven Environmental Unit. None of the pollutants that were measured surpassed its threshold limit value. The average concentrations of the pollutants that were measured could be considered as preliminary standard for environmental units in hospitals as long as material analysis for outgassing is used simultaneously.
