Determination Emitted Gasses from Using Three Types of Woods in Grilling Meats


The randomly using of different woods in grilling meats may cause severalhealth and environmental effects due to various gasses emitted from burning suchwoods. The current work has examined the type and concentration of several emittedgases from burning raw tree wood, wood charcoal and palm fronds. This study hasmeasured volatile organic compounds (VOC), carbon mono oxide (CO), ozone (O3),hydrogen sulfide (H2S) and sulfur dioxide (SO2). The concentrations of these emittedgasses were measured at fire start point, 15, 30 and 60 minutes.It has been found thatraw 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 ppmand 48.6 ± 0.123 ppm. On the other hand, wood charcoal had emitted mean valuesvarying from 1.33 ± 0.17 to 2.97 ± 0.13 ppm. For carbon monoxide, raw tree woodgave mean values varied from 39.6 ± 4.65 ppm to 442.67 ± 71.6 ppm while palmfronds 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 almostsimilar mean values varied from 0.02 ± 0.0 ppm to 0.02 ± 0.01 ppm and palm frondsshowed mean values ranged from 0.0267±0.009 ppm to 0.0433±0.005 ppm. Inaddition, 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 ± 1.699ppm to 23.37 ± 0.69 ppm. Palme fronds have given mean value varying from1.267±0.205 ppm to 1.267±0.205 ppm. Meanwhile, wood charcoal smokes were freefrom H2S. The sulfide dioxide emitted from raw tree wood showed mean value rangedfrom 0.33 ± 0.06 ppm to 1.173 ± 0.17 ppm. While palm fronds had almost constantmean values, during all combustion intervals, lying from 0.433±0.205 to 2.4±0.38ppm. Wood charcoal had mean values varied from 0.3±0.04 ppm to0.57 ±0.09 ppm.
