当前对于不同目的的地下水污染评价工作往往倾向于突出选择微量元素(毒物类和重金属类)作为评价指标,而常常忽略水化学分析中常规离子参与评价和示踪的作用,这大概由两种错觉形成:一是认为微量指标对人体危害程度大;二是偏面的认为所谓地下水污染,尤其是现代工业“三废”对地下水渗透污染,主要是指这些微量元素。但是,就阐述地下水污染规律及其评价污染程度等技术性问题而言,常规水化学指标中某些离子要比微量元素优越得多。地下水
At present, groundwater pollution assessment for different purposes often tends to highlight the selection of trace elements (toxic and heavy metals) as the evaluation index, and often ignores the role of conventional ions in the evaluation and tracing of water in chemical analysis of water, which is probably caused by two kinds of illusions Formation: First, that micro-indicators of the degree of harm to the human body; Second, partial view that the so-called groundwater pollution, especially the modern industrial “three wastes” pollute groundwater, mainly refers to these trace elements. However, in terms of describing the law of groundwater pollution and its technical problems such as the degree of pollution evaluation, some ions in conventional hydration indicators are much superior to trace elements. groundwater
