虽然化学制剂给人们日常生活带来很多便利,但是,化学制剂在生产和使用过程中均存在许多问题。据世界卫生组织统计,发展中国家每年约有50万人遭受化学制剂的危害。而有关资料也表明,与20世纪60年代相比,近年儿童癌症发病率增加了5%,这与家庭过多使用家用化学制剂有关。 Although chemical products bring many conveniences to people’s daily life, there are many problems in the production and use of chemical agents. According to the statistics of the World Health Organization, about 500,000 people in developing countries are exposed to chemical hazards each year. The data also show that compared with the 1960s, the incidence of cancer in children in recent years increased by 5%, which is related to the family too much use of household chemicals.
