在毛主席“备战、备荒、为人民”的伟大战略方针指引下,我国各条战线正在开展一场大搞综合利用,消除和处理好“三废”的群众运动。在开展“三废”卫生工作中,制定地面水中常见工业毒物的限量标准,是一个重要方面。随着我国石油化学工业生产的迅速发展,以石油副产品丙烯为原料合成丙烯腈时,能产生乙腈、丙烯醛等工业毒物,随污水排入水体。为了确定乙腈排入水体后对水质和人民健康的影响,并为工业企业利用和净化含乙腈的废水提供卫生方面的依据,我们受有关工厂的委托,对乙腈在水中的限量标准进行了研究。
Under Chairman Mao’s great strategic guideline of “preparing for war, preparing for war and for the people,” all walks of our country are carrying out a mass movement that vigorously promotes the comprehensive utilization, eliminates and deals with the “three wastes.” In carrying out the “three wastes” health work, it is an important aspect to formulate a limited standard of common industrial toxicants in surface water. With the rapid development of the production of petrochemical industry in our country, the industrial toxins such as acetonitrile and acrolein can be produced when acrylonitrile is synthesized from petroleum byproduct propylene, and discharged into the water with the sewage. In order to determine the impact of acetonitrile on water quality and people’s health after being discharged into the water, and to provide a hygienic basis for industrial enterprises to utilize and purify acetonitrile-containing wastewater, we commissioned the relevant factories to study the limits of acetonitrile in water.
