在人们的生活环境中,存在着可疑的致癌因素。随着人工合成的各种化学物品的数量不断增加,可疑的致癌因素也日趋增多。应当通过标准而完整的实验研究逐一确定各可疑因素是否具有致癌性,这是开展人类癌症预防工作的一个前提。现今,检测可疑致癌物质的方法,按其可靠程度的高低、采用时所耗费的力量和时间的多少以及评定指标的不同,可粗分为四级。本文作者在按照第三级检测方法(即生活整体
In people’s living environment, there are suspicious carcinogenic factors. With the increasing number of synthetic chemicals, the suspicious carcinogenic factors are also increasing. It is a prerequisite for cancer prevention in human beings to determine whether each suspicious factor is carcinogenic by standard and complete experimental studies. Today, the detection of suspicious carcinogenic substances, according to their level of reliability, the amount of time and the amount of time spent as well as the assessment of the different indicators can be roughly divided into four levels. The author in accordance with the third level of detection methods (that is, the overall life
