| Abstract | ||
| The randomly using of different woods in grilling meats may cause several health and environmental effects due to various gasses emitted from burning such woods. The current work has examined the type and concentration of several emitted gases from burning raw tree wood, wood charcoal and palm fronds. This study has measured volatile organic compounds (VOC), carbon mono oxide (CO), ozone (O3), hydrogen sulfide (H2S) and sulfur dioxide (SO2). The concentrations of these emitted gasses were measured at fire start point, 15, 30 and 60 minutes.It has been found that raw tree wood gave highest mean value of VOC ranged from 6.61± 0.57 to 173.67 ± 12.52 ppm whilst palm fronds showed mean values lying between 17.67 ± 2.726 ppm and 48.6 ± 0.123 ppm. On the other hand, wood charcoal had emitted mean values varying from 1.33 ± 0.17 to 2.97 ± 0.13 ppm. For carbon monoxide, raw tree wood gave mean values varied from 39.6 ± 4.65 ppm to 442.67 ± 71.6 ppm while palm fronds showed mean values ranged from 39.47 ± 4.706 ppm to 432.67 ± 51.598 ppm. In addition, wood charcoal has been found to have mean values varying from 17.67 ± 2.32 ppm to 62.33 ± 3.44 ppm. In case of ozone content, raw tree wood had almost similar mean values varied from 0.02 ± 0.0 ppm to 0.02 ± 0.01 ppm and palm fronds showed mean values ranged from 0.0267±0.009 ppm to 0.0433±0.005 ppm. In addition, wood charcoal had almost similar mean values (0.04 ± 0.0 – 0.043 ± 0.03) during all combustion intervals but higher than those of other burning materials. Regarding hydrogen sulfide, the raw tree wood had a rang mean value of 4.43 ± 1.699 ppm to 23.37 ± 0.69 ppm. Palme fronds have given mean value varying from 1.267±0.205 ppm to 1.267±0.205 ppm. Meanwhile, wood charcoal smokes were free from H2S. The sulfide dioxide emitted from raw tree wood showed mean value ranged from 0.33 ± 0.06 ppm to 1.173 ± 0.17 ppm. While palm fronds had almost constant mean values, during all combustion intervals, lying from 0.433±0.205 to 2.4±0.38 ppm. Wood charcoal had mean values varied from 0.3±0.04 ppm to0.57 ±0.09 ppm. | ||
