I would like to discuss with you about the variations of test results taken for particulate Matter (PM 10 and/or PM2.5) from both method. Discussion based on experimental results and references is highly appreciated.
Well, the literature shows difference obtained in both these methods. It varies with data utilization techniques. The water content of atmospheric aerosols greatly influences their mass concentrations. The concentration difference between methods increased with relative humidity ..... seasonally variation is also founded in literature ..... The variability also depends on filter materials and semi volatile species.
