Abstract:
This research aims to find the concentration of TSP PM10 PM4 PM2.5 and BTEX from meat grilling as pork meat, chicken meat, chicken wings and chicken internal organ with charcoal oven at Moo Yang shop. The BTEX concentration was used to assess the health risk of seller who was inhalers exposure in worse case. The result found the meat grilling from Moo Yang shop released TSP PM10 PM4 PM2.5 and BTEX at harmful levels to health. Grilling produced TSP at the highest average concentration follow by PM10 PM4 and PM2.5 with the orderly concentrations of 10.27±0.50 6.92±0.59 3.76±0.32 and 1.38±0.24 mg/m3, respectively. This was consistent with the result of sellers interview is indicating occurences of Nasal irritation, nosebleed, cough, sneeze and sputum. These symptoms were the mechanism of dust removal from humans respiratory system. For analyzing the BTEX, it found the average concentrations as following order; Benzene > Toluene > o-Xylene > Ethylbenzene with the orderly concentrations of 0.0323±0.0160 0.0180±0.0090 0.0030±0.0030 and 0.0013±0.0030 mg/m3, respectively with and non detect for m,p-Xylene. The BTEX concentrations were not exceeding work safety limits of OSHA NIOSH and announcement of Ministry of Interior. However, when when used BTEX concentration to assess the health risk in the worst case it found the seller had unacceptable risk of cancer with 1.10x10-5 or 11 persons per 1 million persons but did not have health risk of non-carcinogenic (HIBTEX = 0.152). Therefore, the seller should be self-protect to decrease BTEX inhalation exposure such as choose charcoal that produces incomplete combustion at low rates, use smoke control i.e. hood or fan with chimney to allow smoke lift above the breathing level, wearing a high efficiency mask that can absorb the toxics or filter small particulate as well.
