World power

headquartered in Geneva, Switzerland GivaudanS.A.’s (1963 acquisition of the Roche Group) in Seveso, Italy near a town called ICMESA set up a chemical plant, the production used for cosmetics and pharmaceutical industries a intermediate. In 1969, the plant began producing a product called 2,4,5 - trichlorophenol (TCP) of the product, which is the intermediate for the synthesis of herbicides. As the synthesis process needs 150 ~ 160 ℃ under continuous heating for some time, and therefore highly toxic dioxin-like and create the conditions for the formation.

1976 Nian 7 Yue 10 Ri, ICMESA chemical plants TBC (1,2,3,4 - tetrachlorodibenzo-p) plus alkaline hydrolysis reactor explosion, including reactive materials, as well as the resultant dioxin impurities breaking of chemical substances, including the roof, into the sky, forming a pollution cloud. Dozens of minutes later, the pollution cloud with winds of up to 5m / s under the direction of the wind sent the southeast winds of about 6km, and settled into an area of about 1810 acres of the area, pollution, covering around 7 belongs to the Province of Milan city.

After the accident, the body of local residents has reached so far by the dioxin levels found in the highest level of dioxin in the human body, found at least 183 cases of chloracne patients. The Government has set up a “Seveso special office” responsible for the aftermath of the accident, taken a series of decisive measures: The hardest-hit residents in emergency evacuation; on soil, water, crops, contaminated media to monitor the situation analysis; of public buildings and facilities clean; to all the plants within a radius of 1.5km to landfill; high-contaminated area 40cm thick topsoil all the dig, and then create a file named “BoscodelleQuerce” park. Seveso in particular the work of the Office continued for many years to March 1987 was finally accomplished their mission. Allegedly accumulated a variety of work with the affected regions, dealing with the files related to more than 700 boxes filled with documents.

fact, due to chemical production caused by dioxin-like pollution incidents in history, there are still more than. West Virginia Monsanto in 1949, the German Lutheran Weigeshama of BASF Corporation in 1953, the Rhone-Poulenc of France Grenoble in 1956, Amsterdam, the Netherlands Philips in 1963 years, the U.S. city of Midland, Michigan, Dow Chemical Company in 1964, Hungary Prague Sporlan companies in 1956 to 1969, the United Kingdom’s Colette De Beixia chemical company in 1968, also have experienced similar accidents, the number of victims up to 250 people, found that more than chloracne cases, cause cancer, central nervous system disorder, causing dozens of deaths.

化学事故和二恶英类的一代

总部设在瑞士日内瓦GivaudanS.A。氏（1963年，罗氏集团收购塞维索，附近的一个小镇意大利）呼吁ICMESA成立一个化工厂，化妆品和药品所用的生产行业提出了中间。 1969年，工厂开始生产产品，名为2,4,5 -三氯酚（TCP）的产品的，这是对除草剂合成中间体。由于合成过程需要150〜160持续一段时间，连续加热℃，因此，高毒性二恶英类和创造形成的条件。

1976念7乐10日，ICMESA化工厂禁雷公约（1,2,3,4 -四氯二苯）加碱水解反应堆发生爆炸，包括反应性材料，以及由此带来二恶英杂质化学物质打破，包括屋顶，天空，形成一个污染云。数十分钟后，高达5米的污染云风/下风s的派出约6公里的东南风，把约1810年的土地，污染面积约7亩属于定居米兰市的省。

事故发生后，当地居民的身体已经达到迄今发现二恶英含量增加，在最高的二恶英对人体的水平，至少发现了183例的氯痤疮。政府已成立了一个“塞维索特别办公室”，为事故的善后工作责任，采取了一系列果断措施：在受灾最严重的居民紧急疏散，对土壤，水源，作物，被污染的媒介监测情况进行分析;公共建筑和设施的清洁，所有工厂内的1.5公里半径范围填埋场;高污染地区40厘米厚的表层土的所有挖掘，然后创建一个名为“BoscodelleQuerce”公园的文件。特别是办公室的工作塞韦索为至1987年3月持续了多年，终于完成了使命。据称积累了受影响地区各种各样的工作，与相关文件，充满超过700箱的文件处理。

事实上，由于化学品生产造成的二恶英污染等历史事件，还有超过。西弗吉尼亚州在1949年孟山都，德国路德Weigeshama在1953年巴斯夫公司，法国罗纳普朗克，法国格勒诺布尔于1956年，阿姆斯特丹，在一九六三年荷兰飞利浦公司，在美国密歇根州Midland，陶氏化学公司在1964年，匈牙利的美国城市在1956年布拉格斯波兰公司到1969年，英国的科莱特者Beixia化工公司于1968年，也经历过类似的事故，受害者的人数多达250人，发现超过氯痤疮的案件，引起癌症，中枢神经系统紊乱，导致数十人死亡。06.9.29
