At Harvard, what are some of the sources of the air pollutants listed above?
PM, VOC, CO, NOx, and SO2 emissions typically result from the combustion of fuel from the operation of equipment such as boilers, furnaces, space heaters, hot water heaters, and emergency generators (emergency stand-by engines). VOC emissions result from the use of volatile organic chemicals in the laboratory and in maintenance operations. Some of these emissions may also be considered HAP. O3 is formed in the atmosphere from chemical reactions which involve VOC and NOx. HAP emissions result from the use of certain types of volatile organic chemicals in the laboratory and in maintenance operations of certain combustion equipment as well as the use of radioactive materials in the laboratory.
