我国土壤重金属污染呈日趋加剧的态势,防治形势十分严峻,重金属污染事故在全国范围内皆有报道!西部地区西部地区地域辽阔,资源丰富,自从改革开放以来,国家对于西部地区矿产资源的开发以及工业化发展,使西部地区产生严重的土壤污染。
西部地区土地的主要污染物是重金属如汞、镉、砷、铜、铅、铬、锌、镍等,其中云南,四川,甘肃白银市市、内蒙古河套地区污染较严重,云南地区单个元素超标率在30%以上的达到37个县,而在河套地区共有近30万人受砷中毒威胁。
西部地区土壤重金属污染源主要包括:(1)废弃的油田、矿场以及矿场的尾矿通过排水和土地渗漏等渠道扩散到周围土地,使土壤遭受污染。
(2)由于西部地区干旱少雨,引进流域水进行灌溉是主要方式,河流中的工业废弃物及重金属经过灌溉方式进入农田土壤环境,进而污染土壤。
(3)西部地区重污染企业的土地污染主要是由于生产中的遗洒、废物堆埋、气态污染物沉降既污水下渗等原因日积月累长期污染引起的。
由于西部地区拥有广袤的土地及矿山林地,所以西部地区所产生的土壤重金属污染修复适合采用生态修复工程,如新余市废旧铅锌矿和铁矿区治理和陕西凤县铅锌镍污染土壤修复示范工程采用生态修复的方法,集中连片开发,发展花卉苗木产业,不仅取得了良好的处理效果及经济效益,更是美化了环境。

土 壤(Soils), 2007, 39 (3): 393~399上海宝山区城市表土重金属累积的空间分布规律①叶 荣1,2, 胡雪峰1,2, 潘 赟2, 苏 玉2, 张甘霖1(1土壤与农业可持续发展国家重点实验室(中国科学院南京土壤研究所), 南京 210008; 2 上海大学环境科学与工程系,上海 200072)摘 要:检测了上海宝山区127个表土样点的重金属含量。
宝山区表土Zn、Cr、Cd、Pb、Cu、Ni、Mn的平均含量分别为228.6、127.6、0.56、118.5、55.2、55.7、718.7 mg/kg。
其中Pb、Zn、Cd的含量分别是上海土壤背景值的5.6、3.0、2.8倍,受污染较明显。
宝山区地表的重金属含量呈现出明显的空间分布规律:工业区地表,如吴淞、大场等地,多种重金属污染均很重,Zn、Cr、Cd、Pb、Cu的平均含量分别高达407.6、319.0、0.75、101.2、76.2 mg/kg;马路绿地土壤Pb的累积较显著,平均为180.2 mg/kg;远郊菜地土壤重金属污染不明显。
关键词: 城市表土;重金属;上海中图分类号: X53城市化已是世界性的普遍现象,是社会进步的标志。
城市化进程的不断加快对我国经济的持续稳定发展和人民生活水平的稳步提高具有重要意义,但是随之而来的城市环境问题不容忽视。
城市化对土壤环境产生深刻影响,城市污水灌溉、工业三废排放、交通、城市生活垃圾等都会导致土壤中重金属等污染物的累积[1]。
科学家们用“化学定时炸弹”来形象地描述土壤污染物的潜在危害[2-5]。
城市土壤重金属的超量累积会对地表水和地下水构成威胁,还会提高大气悬浮颗粒中的重金属负荷,直接影响人体健康[6];城郊农业土壤重金属累积,会使重金属进入食物链,危害人体健康[7]。
研究表明,与农业土壤相比,城市土壤中重金属元素含量明显偏高[8]。
城市交通运输是城市土壤重金属污染的一个重要来源,汽车尾气排放、轮胎添加剂中的重金属元素均可影响到土壤中Pb、Zn、Cu的含量,且这些元素的积累量都与交通流量有关[9-10]。

部分城市放射性异常中国绘制土壤重金属污染图“镉米”的出现是一个不好的预警。
清除“镉米”背后的土壤污染,最重要任务之一就是全面会诊土壤重金属污染现状。
记者获悉,为清除“镉米”,我国国土资源部、中国地质调查局正在绘制土壤重金属“人类污染图”。
我国正建立涵盖81个化学指标(含78种元素)的地球化学基准网:以1:20万图幅为基准网格单元,每一个网格都布设采样点位,每个点位各采集一个深层土壤样品和一个表层土壤样品。
深层样品来自1米以下,代表未受人类污染的自然界地球化学背景;表层样品来自地表25厘米以浅,是自然地质背景与人类活动污染的叠加。
用表层含量减去深层含量,即得出重金属元素“人类污染图”。
从1994年起,中国地质科学院地球物理地球化学勘查研究所等机构就对全国土壤51种化学元素进行监测,1999年起对东部农田区54种化学元素进行填图,2008年起建立全国地球化学基准网,对含78种元素的土壤81个化学指标进行探测。
数据显示,重金属等污染物指标在大的流域及局部工矿业和农业区上升较快。
全国多目标区域地球化学调查项目已发现局部地区土壤污染严重。
如长江中下游某些区域普遍存在镉、汞、铅、砷等异常。
城市及其周边普遍存在汞铅异常,部分城市明显存在放射性异常。
湖泊有害元素富集,土壤酸化严重。
研究证实,镉、汞等重金属元素与人类污染存在密切关系。
重金属元素在土壤表层明显富集并与人口密集区、工矿业区存在密切相关性。
与1994~1995年采样相比,土壤重金属污染分布面积显着扩大并向东部人口密集区扩散。
经地质学家研究表明指出,我国土壤正出现越来越多本来没有或微不足道的危险元素。
土壤一旦被污染,通过自净能力完全复原周期长达千年。
为人类健康,必须持续加大对污染行为监管和惩治力度。
对已被污染土地,要把污染源搞清楚并加以切断。
土壤污染物不仅有重金属,还有大量有机污染物。
国土、地质、环境、水利等部门要通力合作为大地“排毒”。
湖南“镉米”究竟为何出现近期,湖南大米不时被检出镉超标,“鱼米之乡”光环被罩上一层阴影,湖南2/3耕地酸化。
