Manual Calculation Methods for Air Pollution Inventories.
Abstract
In the assessment and control of air pollution, there is a critical need for reliable and consistent data on the quantity and characteristics of emissions from the numerous sources that contribute to the problem. The large number of individual sources and the diversity of source types makes conducting field measurements of emissions impractical on a source by source basis. The only feasible method of determining pollutant emissions for a given community or base is to make general emission estimates typical of each of the source types. Compilation of these emission estimates or airborne pollutant discharges including oxides of nitrogen (NO(x)), oxides of sulfur (SO(x)), hydrocarbons (HC), carbon monoxide (CO), and particulates (PA) over a period of time, usually one year, is referred to as an Emissions Inventory. A useful tool for estimating general emissions for an emissions inventory is the emission factor. This is an estimate of the rate at which a pollutant is released to the atmosphere as a result of some activity (such as combustion or industrial production) divided by the level of that activity. The use of emission factors for manual calculation of emissions as well as data collection procedures necessary for completion of the emissions inventory are provided within. This report provides guidelines for bioenvironmental engineers and technicians on how to perform Air Emission Inventories (AEIs). This report provides example calculations, blank data sheets, emission factors, and an example completed AEI. (aw)
