| 中文摘要 |
| 以浙江台州6家典型化学合成类制药企业为代表，对其排放工艺废气中的18项挥发性有机物（VOCs）特征污染物（如甲苯、甲醛、二氯甲烷等）进行监测和分析，并采用臭氧产生潜力（OFP）和健康风险评价指标对VOCs所产生的环境与健康危害进行初步的评价.结果表明，化学合成类制药企业排放的总VOCs浓度为14.9~308.6 mg·m-3，其产生环境危害的OFP值为3.1~315.1 mg ·m-3，主要贡献物质为甲苯、四氢呋喃、乙酸乙酯等6种物质，存在较大的潜在环境危害.另外，健康危害中的非致癌风险指数和总致癌风险指数介于9.48×10-7~4.98×10-4 a-1和3.17×10-5~6.33×10-3之间，主要是苯、甲醛和二氯甲烷这3种致癌物. |
| 英文摘要 |
| In this study, volatile organic compounds (VOCs) released from chemical synthesis pharmaceutical industry in Taizhou, Zhejiang province were analyzed quantitatively and qualitatively. The total volatile organic compounds (TVOCs) was in the range of 14.9-308.6 mg ·m-3. Evaluation models of ozone formation potentials (OFP) and health risk assessment were adopted to preliminarily assess the environmental impact and health risk of VOCs. The results showed that the values of OFP of VOCs were in the range of 3.1-315.1 mg ·m-3, based on the maximum incremental reactivity, the main principal contribution was toluene, tetrahydrofuran (THF), acetic ether etc. The non-carcinogenic risk and the carcinogen risk fell in the ranges of 9.48×10-7-4.98×10-4 a-1 and 3.17×10-5-6.33×10-3. The principal contribution of VOCs was benzene, formaldehyde and methylene chloride. |
