A Gis Model For Pm10 Exposure From Biomass Burning In The North Of Thailand, Borworn Mitmark, Wanida Jinsart
Applied Environmental Research
Human exposure to particulate matter with an aerodynamic diameter below 10 µm (PM10) is found to be associated with biomass burning in Thailand. Recent investigations confirm that primary sources of PM10 are natural forest fires and agricultural waste burning. Incidence of atmospheric haze increases significantly during the dry season from January to April. PM10 exposure in eight provinces in Northern Thailand were determined using GIS through spatial interpolation. Daily average ambient PM10 concentrations from 10 monitoring stations were used as the input data for the GIS model. Three interpolation techniques: Inverse Distance Weighted (IDW), Kriging and Spline, were compared. The …
