本文报导了利用紫露草染色体微核技术,监测海水污染的初步实验结果。我们发现紫露草能于海水中在实验要求的时间内成活,并通过实验证实了微核产生的原因不是海水本身,而是海水中的污染物质,污染物质含量越高,产生微核的频率也越高。因此,可用它来监测海水的污染,同时,对青岛食用自来水的质量也作了测定,就诱变物质来讲,目前青岛自来水的清洁度是好的。 This paper reports the preliminary experimental results of the monitoring of seawater pollution by using the chromosome-micronucleus technique. We found that the sphagnum can survive in the seawater for the required time of the experiment and confirmed by experiments that the cause of the micronucleus is not the seawater itself but the pollutants in the seawater. The higher the pollutant content, the more the frequency of the micronucleus is high. Therefore, it can be used to monitor the pollution of sea water, at the same time, the quality of tap water was also measured in Qingdao, mutagenic substances, the current cleanliness of Qingdao tap water is good.
