Assessing the level of air pollution at some small-scale household waste incinerators in Hai Hau district, Nam Dinh province
Tóm tắt
In this study, sixteen air samples from two small-scale household waste incinerators in Hai Hau district, Nam Dinh province, Vietnam, were collected and investigated for some pollutants such as SO2, NO2, CO, H2S, and BTEX. The results showed that the concentration of SO2, NO2, CO, and H2S were correspondingly in the range of 351.1 -450.0, 30300-36600, 200.7-212.0, and 78.9-100.1 µg/m3. In addition, the BETX concentration ranged from 5.16 to 20.7 µg/m3 for Benzen, from 21.63 to 120.66 µg/m3 for Toluen, from 3.13 to 12.57 µg/m3 for (m, p)-Xylene, and from 1.58 to 7.73 µg/m3 for o-xylene. All the values of SO2, NO2, CO, and H2S concentration were higher than standard concentrations in QCVN 05: 2013/BTNMT, however, the BETX concentration was lower than the standards in QCVN 06:2009/BTNMT.
