Abstract
This experiment continues the work of Wu(2014) 「Emission of Air Pollutants from Charcoal Combustion in Indoor Environment」, base on Wu(2014) results to select three kinds of charcoals, that is lower in hazard quotient: Longan charcoal (T3), binchoutan (B1), Carbon (I1S). To simulate the actual barbecue pollutant emission, , and to test pollutant emission differences on varies pollutants by adding oil, oil type, and different charcoal species. We monitor the result by using aerosol monitor (Dusttrak), dust monitor (EPAM-5000), multi-gas analyzer (HM-5000), DNPH chemical absorption, Tenax-TA sorbent. And analysis emission of HC, CO, CO2, NOx, PM10, PM2.5, aldehyde and ketone compounds, volatile organic compounds and heavy metals which emitted from charcoal combustion. The emission data was calculated as emission factors and emission rates. Experimental result shows that the type of charcoal for various pollutants (HC, CO, CO2, NOx, PM10, PM2.5, aldehyde and ketone compounds, volatile organic compounds, heavy metals) emission factors are significant differences (p-value <0.05), except arsenic(As), copper(Co), lead(Pb), zinc(Zn).Adding oil also have significant difference (p-value <0.05) for hydrocarbons, carbon dioxide, suspended particulates, aldehyde and ketone compounds, volatile organic compounds emissions factor, but grease types do not have significant difference for all pollutant emission factor. Hydrocarbon emission factor without oil adding is in the range of 5025.60 ~ 7924.02mg kg-1, and after adding oil hydrocarbon emission factor in the range of 6029.82 ~ 10629.40 mg kg-1, carbon monoxide emission factors is in range of 106.04 ~ 395.84 g kg-1, carbon dioxide emission factors in the case of not adding oil is in range of 1350.76 ~ 2432.29 g kg-1, and 1929.50 ~ 3026.10 g kg-1 after adding oil, nitrogen oxide emission factor of 193.11 ~ 582.41 mg kg- 1, formaldehyde emission factors when not add oil to 19.23 ~ 37.71 mg kg-1, after adding oil to 33.10 ~ 49.41 mg kg-1, acetaldehyde emission factor when no added fat was 8.90 ~ 20.64 mg kg-1, and adding oil was 14.25 ~ 26.67 mg kg-1, PM10 emission factor when no added fat was 32.82 ~ 562.54 mg kg-1, after adding oil to 1611.33 ~ 4800.55 mg kg-1, PM2.5 emission factor when no added fat was 14.27 ~ 454.15 mg kg-1, after adding oil is 1029.38 ~ 4065.14 mg kg-1, benzene emission factor when no added fat is 0.26 ~ 3.15 mg kg-1, after adding oil to 4.76 ~ 13.70 mg kg-1, toluene emission factor of 0.26 ~ 1.93 mg kg-1, after adding oil as 2.35 ~ 9.06 mg kg-1, total heavy metal emission factor of 8427.85 ~ 10333.21 ug kg-1. Charcoal burning with oil increases the number of various kinds pollutant emission factors and concentration, such as PM2.5 and PM10 emission concentrations were increased by 10 to 100 times. Without adding any oil to charcoal burning the pollutant emission was exceeding the limit of regular indoor standard. After adding oil, the pollutant emission was exceeding the standard over a hundred times. This shows that indoor barbecue will cause great pollution, and we cannot ignore its harm to human health. Many pollutant concentrations has exceeded ASTDR inhaled MRLs, over hundreds of times more than the acute criteria. In addition many barbecue restaurants with simple exhaust device that discharged pollutant directly to the outdoor environment, without reduction and control this will be a huge impact to outdoor environment.
