Abstract of the Article
This report presents the initial research results of applying the Fixed Box Model to calculate the temporal variance of the concentration of particulate matter of 10 micrometers (PM10) one of the air pollutants that most commonly affects people's health. The input parameters (area source capacity of PM10, wind speed, mixing height, size of area source) were estimated based on the area source emission inventory results including: road source, mobile source, construction source, industry source and household domestic source in Thanh Xuan District. This emission inventory project was carried out from 9/2007 to 3/2008 by Hanoi Center for Environmental and Natural Resources Monitoring and Analysis (CENMA) and Research Center for Environmental Monitoring and Modeling (CEMM) Hanoi University of Science, of which, CEMM played a consultative role. The project was sponsored by the Swiss Vietnamese Clean Air Program (SVCAP). The results show that:
-The graph describing the temporal variance of the concentration of PM10 has an exponential function, rising gradually until it reaches a saturated state.
-Concentration of PM10 C(t) is in inverse proportion to wind speed (U) and mixing height (H) at a fixed box length (L) and area source capacity (Ms).
-There exists a specific time constant τ for life time of pollutants in each case.
-The results from the Fixed Box Model are verified by real data get high accuracy.
