[Objective]To master the status of heavy metal pollution in some vegetable plots in Hengyang.[Method]The cadmium (Cd) and lead (Pb) content in garlic grown on the farmland near the Linghu college town of Hengyang in Hunan were investigated.[Result]The vegetable Cd in the vegetable garden near the south of the university was more serious than Pb,and the overall pollution level was low,only partially exceeding the standard value.Cd pollution was more serious in the vegetable garden near the west end of the university,while Pb pollution was less serious.Pb pollution was more serious in the vegetable garden near the east of the university,and Cd pollution was less.The pollution of Cd and Pb of garlic in vegetable garden of north university was serious.The total content of Cd in garlic samples at 4 sampling sites was 66.7%,and that of Pb was 54.1%.[Conclusion]The Cd and Pb pollution around Linghu college town of Hengyang were serious.%[目的]掌握衡阳市部分菜地重金属污染现状.[方法]在湖南省衡阳酃湖乡大学城附近采集大蒜样本,测定其中镉(Cd)和铅(Pb)的含量.[结果]大学城南附近菜地大蒜Cd污染比Pb严重,但整体污染程度较低,仅部分超过标准值;大学城西附近菜地大蒜Cd污染比较严重,而Pb污染较轻;大学城东附近菜地大蒜Pb污染较重,Cd污染较轻;大学城北菜地大蒜Cd、Pb污染均较严重.4个采样点大蒜Cd总超标率为66.7%,Pb的总超标率为54.1%.[结论]湖南省衡阳酃湖乡大学城附近菜地Cd、Pb污染较为严重.
