Documentation and General Calibration
Published in Howard E. Hesketh, Air And Waste Management, 2019
For certain purposes of federally mandated monitoring, the EPA requires mat the concentrations of calibration gases contained in compressed gas cylinders be determined by measuring pollutant concentrations generated by the gases using ambient air quality analyzers that have been calibrated using NBS standard reference materials (SRMs) or certified reference materials (CRMs). An EPA-recommended procedure for these determinations, entitled ‘‘Traceability Protocol for Establishing True Concentrations of Gases Used for Calibration and Audits of Air Pollution Analyzers (Protocol No. 2),” is contained in EPA 600/4-77-027a Quality Assurance Handbook for Air Pollution Measurement Systems: Volume II.

Air pollution is affected by many formations such as traffic, factory, and population density and varies based on measurement stations in cities. In air pollution measurement, SO2, NO2, CO, O3, and PM10 are frequently used parameters that are required to be measured by the authorities of many countries. In the measurement stations of the cities, measurements are taken according to these substances and air pollution is determined by limit values of each parameter. As the pollution rate increases, the negative effects that may occur due to these substances become vitally important. It is significant to determine the negative effects of the parameters based on the city and/or station and to minimize the diseases and environmental effects that may occur due to the hazards arise from substances.
