在环境卫生领域内,近十多年来有效地从理论上探讨了环境致癌物卫生标准的科学基础问题。苏联自七十年代来,最早研究和批准了环境强致癌物之一——苯并(a)芘在大气(1972)、车间空气(1973)、水体(1978)和土壤中(1979)的最高容许浓度。制定致癌物标准的方法原则就是苏联卫生学家公认的阈作用的概念,即认为致癌物对机体的作用亦存在“剂量-时间-效应”的数量相
In the field of sanitation, the scientific basis of sanitation standards for environmental carcinogens has been effectively explored theoretically for more than a decade. Since the 1970s, the Soviet Union has first studied and approved the highest environmental carcinogen - benzo (a) pyrene in the atmosphere (1972), workshop air (1973), water body (1978) and soil Allowable concentration. The principle of establishing a carcinogen standard is the concept of the threshold effect recognized by the Soviet hygienists that the role of carcinogens in the body also exists in the quantity-time-effect phase
