In this study, trends in hazardous pollution emissions in South Korea for the last decade were investigated to protect people’s health and contribute to the prevention of environmental risks by reducing emissions. It was found that hazardous pollution emissions increased from 47,688,000 kg in 2007 to 57,247,000 kg in 2016. Among them, Xylene and Toluene exhibited the highest proportions. 99% of hazardous pollution were emitted to the atmosphere. Among the Group 1 carcinogens, the top two substances (trichloroethylene, benzene) accounted for more than 80% of the emissions, and trichloroethylene took up the most. Carcinogen emissions also increased, and emissions from major industrial complexes represented approximately 30% of the total chemical emissions from all industrial complexes. Chemical emissions exhibited no significant relationship with particulate matter, cancers, and allergic diseases. It can be said, however, that the use of various chemicals has chemical accident risks. Owing to the nature of chemical accidents, an accident may lead to secondary damage. Therefore, it is necessary to prepare measures for the management of various chemicals and to perform continuous monitoring for reducing chemical emissions. The purpose of this study was to identify the trends in Korea emissions of hazardous chemicals from 2007 to 2016. In 2007, 47,688,000 kg of chemical substances were emitted at 3012 places of business across the country while 57,247,000 kg were emitted at 3732 places in 2016. The number of workplaces and emissions increased by about 1.2 times over 10 years, and most of them were discharged to the environment through the atmosphere. The top five chemical substances accounted for 60% of the total chemical emissions. Xylene ranked first in 2007–2016, followed by toluene. Although slightly different depending on the year, it was found that Ethylacetate, Methylethylketone, Ethylbenzene, etc. are released a lot. In the case of carcinogens, dichloromethane, ethylbenzene, and trichloroethylene accounted for more than 65% of the total carcinogen emissions even though there were slight differences for each year. In addition, Group 1 and Group 2A materials tended to decrease, but emissions of Group 2B materials tended to increase continuously. Major industrial complexes with high emissions accounted for about 30% of the total industrial complex chemicals. Emissions were highest in Ulsan•Mipo Industrial Complexes. Various chemicals were used according to the characteristics of the industrial complex. Recently, the use of chemicals and their emissions have continued to increase. Consideration should be given to the management of chemicals in consideration of the regional characteristics of each industrial complex.

2007-2016年韩国有害污染物排放特征研究

在这项研究中，调查了韩国过去十年危险污染排放的趋势，以保护人们的健康，并通过减少排放来预防环境风险。发现有害污染排放量从2007年的4768.8万公斤增加到2016年的5724.7万公斤，其中二甲苯和甲苯占比最高。99%的有害污染物排放到大气中。第一类致癌物中，前两种物质（三氯乙烯、苯）排放量占80%以上，其中三氯乙烯占比最高。致癌物排放量也有所增加，主要工业园区的排放量约占所有工业园区化学品排放总量的 30%。化学排放与颗粒物、癌症和过敏性疾病没有显着关系。然而，可以说，各种化学品的使用都存在化学事故风险。由于化学事故的性质，事故可能导致二次损害。因此，有必要制定各种化学品的管理措施，并进行持续监测以减少化学品排放。本研究的目的是确定 2007 年至 2016 年韩国危险化学品排放的趋势。 2007 年，全国 3012 个营业场所排放了 47,688,000 公斤化学物质，而 2016 年 3732 个营业场所排放了 57,247,000 公斤。工作场所的数量和排放量在 10 年间增加了约 1.2 倍，大部分通过大气排放到环境中。前五种化学物质占化学物质排放总量的60%。二甲苯在 2007-2016 年排名第一，其次是甲苯。虽然因年份而略有不同，但发现乙酸乙酯、甲乙酮、乙苯等大量释放。就致癌物而言，二氯甲烷、乙苯和三氯乙烯占致癌物排放总量的65%以上，尽管每年略有不同。此外，Group 1 和Group 2A 材料有减少的趋势，而Group 2B 材料的排放量有持续增加的趋势。高排放的主要工业园区占工业园区化学品总量的30%左右。蔚山•美浦工业园区的排放量最高。根据工业园区的特点使用了各种化学品。最近，化学品的使用及其排放量持续增加。化学品管理应结合各工业园区的地域特点加以考虑。
