过去,要知道水是否受到污染,科学家采用的生物检测法通常是将活鱼放入待测水中,根据鱼的健康状况来判断水的毒性和被污染的程度。这样做,至少要用四天或四天以上的时间,不仅耗时长不及时,而且灵敏度低、误差很大。最近,美国辛辛那提大学环境遗传学家丹尼尔·内博特和威斯康星州密尔沃基大学的 In the past, to know whether water was contaminated, the biometric method used by scientists was usually to put live fish into the water to be measured, and to judge the degree of toxicity and contamination of water based on the fish’s health status. In doing so, it takes at least four days or more, which is not only time consuming and time consuming but also has low sensitivity and errors.
