Volatile organic compounds (VOCs) are generated from animal rendering facilities, some of which are malodorous, while others are considered hazardous. Odor annoyance potential, possible carcinogenic risks, and toxic effects due to VOC emissions from a rendering plant unit in Southwest Greece were evaluated for the general population residing in the near vicinity. Nine air samples were collected from the facilities of an integrated rendering plant and the surrounding area, over a 9-month period. Volatile compounds were absorbed onto solid sorbents containing Tenax TA/Sulficarb via active sampling and analyzed by thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). Sixty-three organic compounds, mainly volatile fatty acids, aldehydes, aromatic, and sulfur compounds, were quantified, in concentrations ranging from < 0.01 to 210 μg m−3. The compounds contributing most to odor nuisance were butanoic acid, dimethyl trisulfide, and octanal, exceeding their odor threshold by up to 24, 36, and 117 times, respectively. Cancer and non-cancer risks were determined by a probabilistic risk assessment method. The cumulative lifetime cancer risk for the general population was calculated to be on average 10 times higher than the acceptable risk (one-in-a-million). The cumulative mean hazard quotient was 3.3 and its 95th percentile was 4.0, indicating a high risk of adverse health effects. Control measures to prevent the generation of the VOCs responsible for both odor nuisance and potential adverse health effects should be adopted.

炼油厂 VOC 排放的气味滋扰和健康风险评估

挥发性有机化合物 (VOC) 来自动物加工设施,其中一些是恶臭的,而另一些则被认为是有害的。对居住在附近地区的一般人群评估了希腊西南部炼油厂单元 VOC 排放引起的气味烦恼、可能的致癌风险和毒性影响。在 9 个月的时间里,从综合提炼厂的设施和周边地区收集了九个空气样本。挥发性化合物通过主动采样被吸收到含有 Tenax TA/Sulficarb 的固体吸附剂上,并通过热解吸-气相色谱-质谱 (TD-GC-MS) 进行分析。对 63 种有机化合物进行了定量分析,主要是挥发性脂肪酸、醛类、芳香族化合物和硫化合物,浓度范围为 < 0。01 至 210 μg m-3。造成气味滋扰最多的化合物是丁酸、二甲基三硫化物和辛醛,分别超过其气味阈值的 24、36 和 117 倍。癌症和非癌症风险通过概率风险评估方法确定。一般人群的累积终生癌症风险经计算平均比可接受的风险(百万分之一)高 10 倍。累积平均风险商为 3.3,其第 95 个百分位数为 4.0,表明对健康不利的风险很高。应采取控制措施,防止产生造成气味滋扰和潜在不利健康影响的挥发性有机化合物。分别超过它们的气味阈值 24、36 和 117 倍。癌症和非癌症风险通过概率风险评估方法确定。一般人群的累积终生癌症风险经计算平均比可接受的风险(百万分之一)高 10 倍。累积平均风险商为 3.3,其第 95 个百分位数为 4.0,表明对健康不利的风险很高。应采取控制措施,防止产生造成气味滋扰和潜在不利健康影响的挥发性有机化合物。分别超过它们的气味阈值 24、36 和 117 倍。癌症和非癌症风险通过概率风险评估方法确定。一般人群的累积终生癌症风险经计算平均比可接受的风险(百万分之一)高 10 倍。累积平均风险商为 3.3,其第 95 个百分位数为 4.0,表明对健康不利的风险很高。应采取控制措施,防止产生造成气味滋扰和潜在不利健康影响的挥发性有机化合物。一般人群的累积终生癌症风险经计算平均比可接受的风险(百万分之一)高 10 倍。累积平均风险商为 3.3,其第 95 个百分位数为 4.0,表明对健康不利的风险很高。应采取控制措施,防止产生造成气味滋扰和潜在不利健康影响的挥发性有机化合物。一般人群的累积终生癌症风险经计算平均比可接受的风险(百万分之一)高 10 倍。累积平均风险商为 3.3,其第 95 个百分位数为 4.0,表明对健康不利的风险很高。应采取控制措施,防止产生造成气味滋扰和潜在不利健康影响的挥发性有机化合物。
