The emission concentrations of a number of aromatic volatile organic compounds (VOCs) and carbonyl compounds were quantified during the combustion of commonly used barbecue charcoal. The concentrations of VOC and carbonyls were determined by gas chromatography coupled with thermal desorption and HPLC method, respectively. The analysis of VOC emission concentrations showed that toluene (116+/-444 ppb) was the most abundant. On the other hand, the carbonyls were dominated by formaldehyde (275+/-477 ppb) and acetaldehyde (126+/-229 ppb). A line of evidence indicates that the emission patterns of these pollutants are associated with the diverse nature of raw materials and the processes involved in their production. Although emission concentrations of target compounds were in most cases below the permissible exposure limits (PEL), a proper regulation against the use of BBQ charcoal is needed to reduce potential health risks associated with its use.
在常用烧烤炭的燃烧过程中，量化了多种芳香族挥发性有机化合物（VOC）和羰基化合物的排放浓度。通过气相色谱与热解吸和高效液相色谱法，分别确定了 VOC 和羰基化合物的浓度。VOC 排放浓度分析表明，甲苯（116+/-444 ppb）是最丰富的。另一方面，羰基化合物主要由甲醛（275+/-477 ppb）和乙醛（126+/-229 ppb）组成。有证据表明，这些污染物的排放模式与原材料的多样性和生产过程有关。尽管目标化合物的排放浓度在大多数情况下低于允许暴露限值（PEL），但仍需要对烧烤炭的使用进行适当的监管，以降低其使用带来的潜在健康风险。
