Abstract
This study was conducted to determine selected air pollutant emissions to the atmospheric environment from burning of rice strawin theopen field. The experiments were conducted at six different paddy fields in Gia Lam district, Hanoi. The particulate matter, PM2.5 andPM10, were collected by mini-volume samplers (5L min-1) and CO was sucked into bags and analyzed by UV-VIS spectrophotometer. CO2was determined continuously by Lutron GCH- 2018 gas sensor. Meteorological conditions were measured by handheld device. The results showed that the combustion efficiency were larger than 0.9, meaning that all major combustion processes were flame ignited. The concentrations of CO and CO2from rice straw burning varied between 10.21 ÷ 56.03 mg/m3and 734.5 ÷ 1221.2 mg/m3, respectively, similar to other studies in the same burning mode. PM2.5, PM10concentrations ranged from 0.71 to 29.07 mg/m3and 3.22 to 37.31 mg/m3, respectively, higher than the results of rice straw burning studies in Thailand and similar to the results in China. This emission level was much higher than the background level and much larger than the level justified in QCVN 05:2013 and WHO, causing air pollution and this may affect health of people living around the burning area. The results of the study provide an useful information for further research to determine the emission factors from rice straw burning and more accurate calculation on the amount of emissions from rice straw burning in agricultural production in Vietnam.
