Particulate Matter (PM10, PM2.5, PM1) indoor Pollution by Using Different Fuel Materials

Abstract

Abstract: Coal, wood, agricultural waste, and liquid petroleum gas (LPG) are among the major fuel materials used for cookstove in Vietnam. However, the use of these energy sources is controversial since they are also the sources of hiden indoor air pollution which could adversely impact human health. In the present study, particulate matter concentrations (PM₁₀, PM_2.5, PM₁) are monitored by GRIMM 107-G (Grimm Technologies, Inc., Douglasville, GA, USA) throughout cooking time using different fuels such as coal, wood, and LPG. The results show that the indoor concentrations of particulate matters tend to be higher than those of ambient air. Among the distinguished fuels, wood produces the highest PM₁₀, PM_2.5, PM₁ concentrations, up to 305.7 ± 105.3 µg/m³; 158.3 ± 35.4 µg/m³; 135.9 ± 31 µg/m³ respectively. The PM₁₀ indoor and outdoor ratios during cooking time using different fuels such as coal, wood, and LPG are 2.67; 1.18; 0.92 respectively. These high concentration of particulate matters in the kitchen is harmful for people, especially the wives in the household who have longer exposure time to those pollutants.

Keywords: Indoor air pollution, cookstove, kitchen room.
