摘要
依據台灣地區空氣污染物排放資料庫(TEDS7.0)資料顯示，全國原生性粒狀污染物之來源，在粒狀污染物(PM10)部分我國原生性污染物排放量為25.2 萬公噸/年，屬逸散污染源部份，營建工程排放比例約佔11%，為我國逸散污染源的管制重點。為了改善營建工地中懸浮微粒之污染狀況，有效減少裸露地揚塵之排放，本研究於5處營建工地裸露地表鋪蓋稻草之PM10以及PM2.5檢測，經由儀器檢測得知結果如下：PM10濃度在5處工地濃度為211 μg/m3，PM2.5濃度在5處工地平均濃度為29.2 μg/m3。PM10最高平均濃度為315 μg/m3，最低為15.6 μg/m3；PM2.5最高平均濃度為59.6 μg/m3，最低為9.6 μg/m3。一般而言營建工地排放之粒狀污染物仍以PM10最多。在營建工地裸露地鋪設稻草，除了可以抑制裸露地揚塵的產生，並且減少農民燃燒稻草的情況。根據環保署統計數據每100平方公尺的稻草鋪蓋，TSP減量成效約2~2.5公斤/月；每鋪設1公頃之稻草蓆可減少約2噸之農廢。

In the study, the emissions of PM10 were calculated according to TEDS7.0 database. 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.
