全面控制挥发性有机化合物(VOCs)的排放对于降低包装和印刷行业的职业健康风险和环境影响至关重要。在这项工作中,我们调查了包装和印刷行业产生的VOCs排放特征和单个污染物的浓度,关于各种类别,进程,和地理区域。VOCs排放量,臭氧形成潜力(OFP),在山东省几个城市的10家代表性包装和印刷公司评估了相关的健康风险,中国。塑料包装企业的无组织VOCs排放水平最高,主要由含氧挥发性有机化合物(OVOCs)组成,其次是烷烃和卤化碳。来自金属和纸包装企业,OVOCs,烷烃,芳烃是无组织VOCs排放的重要组成部分。芳烃,卤化碳,和OVOCs在研讨会上对OFP做出了重大贡献。在包装和印刷行业中,与VOC相关的潜在致癌风险并不显著。然而,根据这项研究的结果,车间环境可能提供相对较高的非致癌风险,可归因于乙酸乙酯,异丙醇,丙烯醛,1,1,2-三氯乙烷,1,2-二氯丙烷,和萘暴露。特别是,苯引起的内分泌干扰和遗传毒性作用,甲苯,苯乙烯,不应该忽视萘。因此,必须优先考虑车间工人的工作环境条件,同时也采取科学和系统的措施来减轻挥发性有机化合物对环境和人类福祉的有害影响。
Comprehensive volatile organic compounds (VOCs) emission control is imperative to decreasing occupational health risks and environmental impact of the packaging and
printing industries. In this work, we investigated the VOCs emission characteristics and concentrations of individual contaminants generated by the packaging and
printing industries, with regard to various categories, processes, and geographic regions. VOCs emissions, ozone formation potential (OFP), and associated health risks were assessed at 10 representative packaging and
printing firms across several cities in Shandong Province,
China. Plastic packaging enterprises had the greatest levels of unorganized VOCs emissions, consisting predominantly of oxygenated volatile organic compounds (OVOCs), followed by alkanes and halocarbons. From metal and paper packaging enterprises, OVOCs, alkanes, and aromatics were significant components of unorganized VOCs emissions. Aromatics, halocarbons, and OVOCs contributed significantly to OFP in workshops. The potential carcinogenic risk associated with VOCs in the packaging and
printing industries was not significant. However, according to the findings in this study, the workshop environment may provide a comparatively elevated non-carcinogenic risk attributable to ethyl acetate, isopropanol, acrolein, 1,1,2-Trichloroethane, 1,2-Dichloropropane, and naphthalene exposure. In particular, the endocrine-disrupting and genetic toxic effects caused by benzene, toluene, styrene, and naphthalene should not be overlooked. Thus, it is essential to provide precedence to the working environment conditions of workshop laborers, while also undertaking scientific and systematic measures to mitigate the detrimental impacts of VOCs on the environment and human welfare.
