The suspended particulate emitted from construction sites accounts for 10% of the fugitive emission sources in Taiwan. In order to improve the suspended particulate pollution in construction sites, the straws were laid at 5 construction sites, and the PM10 and PM2.5 concentrations were measured. The average concentrations of PM10 and PM2.5 at the 5 construction sites are 211 and 29.2 μg/m3, respectively. The PM10 concentrations are from 15.6 to 315 μg/m3 and PM2.5 concentrations are from 9.6 to 59.6 μg/m3. The PM10 emission from construction sites is serious. Laying straw on the construction sites can not only reduce PM emission, but also decrease the burning of straw which would emit even more PM to the atmosphere. According to EPA statistics, 2 to 2.5 kg / month TSP can be reduced for the laying of straw per 100 square meters. Two tons of straw waste can be reduced for 1 hectare of straw laying.
