广州市白云山为国家4A级风景区,部分市民喜欢到白云山取山泉水饮用,但国内对白云山泉水的相关调查较少。遂联同三位资深教师,召集本校部分学生,组建了白云山泉水水质调查科技小分队,并进行了一系列的白云山泉水分析检测实践活动。对白云山若干泉水点进行取样检测,以了解白云山泉水的水质状况及其成因。经检测发现,各水样本均呈弱酸性且硫化物超标(参照GB5749-2006),而其他各项指标均在正常范围内。通过查阅相关资料并对比本次检测结果发现,白云山泉水属于典型的受酸雨污染后的地表水。
Guangzhou Baiyun Mountain is a national 4A-level scenic spot, and some citizens like to take mountain spring water to Baiyun Mountain. However, there are few domestic related investigations on Baiyunshan spring water. Then together with three senior teachers, called part of the school students, set up a Baiyun Mountain spring water quality investigation technology detachment, and conducted a series of Baiyun Mountain spring water analysis and testing practices. A number of spring water samples from Baiyun Mountain were taken to understand the water quality of Baiyunshan spring water and its causes. The test found that the water samples were weakly acidic and sulfide exceeded (refer to GB5749-2006), while the other indicators are in the normal range. By consulting relevant information and comparing the test results, it is found that Baiyun Mountain spring water is a typical surface water polluted by acid rain.
