Air pollution monitoring is conducted to determine either emission concentration or ambient air quality.The range of emission concentrations,temperature and pressures encountered is sometimes different than found in tha ambient air sampling situations.For that reason sampling and analysis technuques and equipment are different for each case.
OBJECTİVES OF SAMPLİNG PROGRAM
The object would be to measure the amount of gaseous and particulate matter at enough locations to make the data statistically significant.It is not uncommon to find each tation in a network equipped with simple, unsophisticated grab sampling devises.However quite afew complicated devises have been developed which contains continuous monitors with telemetry and computer control.Meterological variables are also monitored and corelated with the concentration data.The information is then used;
1.To establish and evaluate control measure
2.To evaluate atmosphric-diffusion model paremeters
3.To determine areas and time periods when hazardous levels of pollution occurs in the atmosphere
4.for emergecncy warning systems
