| 摘 要： | 在河南省某高校校区内的规模绿地上采集21个土壤样品,在郊区农田采集2个对照样品。按照国家标准方法,测定了土壤Cu、Zn、Ni、Pb和Cr的含量。结果发现:校园土壤中Ni、Zn和Cr发生了不同程度的富积;土壤重金属含量空间变异明显;校园土壤普遍发生了Zn污染,平均污染分指数达2.48,中度和重度污染样点占总样点的57.14%;绝大部分样点的综合污染指数均大于1,其中轻度污染样点13个,中度污染样点5个,重度污染样点2个。根据校园土壤的实际,应从严格控制污染物排放、翻土和客土改良、增施有机肥料、植物修复等方面防治校园土壤重金属污染。

| Abstract: | Twenty-one soil samples were collected from campus soils in one of universities of Henan province, and two control samples were collected from unpolluted farmland at suburb of the city. The concentrations of Cu, Zn, Ni, Pb and Cr in the samples were determined according to the national standard methods. The results showed as follows: Ni, Zn and Cr have been accumulated in the campus soils; and the special distribution of heavy metal concentrations in the campus soils changes evidently. All the sampling sites have polluted by Zn and the average of PZn is 2.48, and the heavy and medium pollution sites make up 57.14 percent of the total sampling sites. The integrative pollution indexes of heavy metals in most sampling sites are higher than 1 indicating that all the sampling sites are polluted by heavy metals in different degree. Among the 21 sampling sites, thirteen sample sites were polluted slightly, five sampling sites were polluted moderately by heavy metals, and two sampling sites were polluted heavily. Finally, the author puts forward four suggests such as controlling pollutant emissions, tilling soil and new soil improvement, increasing organic fertilizer, phytoremediation to prevent the heavy metal pollution of campus soils. |
