土壤生物污染一个或几个有害的生物种群，从外界环境侵入土壤，大量繁衍，破坏原来的动态平衡，对人体健康或生态系统产生不良的影响。造成土壤生物污染的污染物主要是未经处理的粪便、垃圾、城市生活污水、饲养场和屠宰场的污物等。其中危险性最大的是传染病医院未经消毒处理的污水和污物。土壤生物污染分布最广的是肠道致病性原虫和蠕虫类造成的污染。全世界约有一半以上的人口受到一种或几种寄生性蠕虫的感染，热带地区受害尤其严重。欧洲和北美较温暖地区以及某些温带地区，人群受某些寄生虫感染，有较高的发病率。土壤生物污染是传布寄生虫病的潜在因素。土壤中致病的原虫和蠕虫进入人体主要通过两个途径：①通过食物链经消化道进入人体。例如人蛔虫、毛首鞭虫(Trichuris trichiura)等一些线虫的虫卵,在土壤中需要几周时间发育，然后变成感染性的虫卵通过食物进入人体。②穿透皮肤侵入人体。例如十二指肠钩虫(Ancуlostoma duodenale)、美洲钩虫(Necator american)和粪类圆线虫 (Strongуloides stercoralis)等虫卵在温暖潮湿土壤中经过几天孵育变为感染性幼虫，再通过皮肤穿入人体。传染性细菌和病毒污染土壤后对人体健康的危害更为严重。一般来自粪便和城市生活污水的致病细菌属于：沙门氏菌属、志贺氏菌属、芽孢杆菌属、拟杆菌属(Bacteroides)、梭菌属、假单胞杆菌属、丝杆菌属(Sphaerophorus)、链球菌属、分枝杆菌属等。另外,随患病动物的排泄物、分泌物或其尸体进入土壤而传染至人体的还有炭疽、破伤风、恶性水肿、丹毒等疾病的病原菌。目前在土壤中已发现有 100多种可能引起人类致病的病毒，例如脊髓灰质炎病毒(Polioviruses)、人肠细胞病变孤儿病毒(Echo virus)、柯萨奇病毒(Coxsackieviruses)等。其中最为危险的是传染性肝炎病毒(Viruses of infections hepatitis)。土壤传染的植物病毒有烟草花叶病毒、烟草坏死病毒、小麦花叶病毒和莴苣大脉病毒等。土壤生物污染不仅可能危害人体健康，而且有些长期在土壤中存活的植物病原体还能严重地危害植物，造成农业减产。例如，某些植物致病细菌污染土壤后能引起番茄、茄子、辣椒、马铃薯、烟草、颠茄等百余种茄科植物和茄科以外的植物的青枯病，能引起果树的细菌性溃疡和根癌病。某些致病真菌污染土壤后能引起大白菜、油菜、芥菜、萝卜、甘蓝、荠菜等一百多种栽培的和野生的十字花科蔬菜的根肿病,引起茄子、棉花、黄瓜、西瓜等多种植物的枯萎病,菜豆、豇豆等的根腐病,以及小麦、大麦、燕麦、高粱、玉米、谷子的黑穗病等。此外,甘薯茎线虫，黄麻、花生、烟草根结线虫,大豆胞囊线虫，马铃薯线虫等都能经土壤侵入植物根部引起线虫病。而剑线虫属(Xiphinema)、长针线虫属(Longidorus)和毛线虫属 (Trichodorus)还能在土壤内传播一些植物病毒。广义来说，这些都属于土壤生物污染引起的病害。研究和掌握这些病害感染的基本规律是轮作防治的基础。污水经二级生化处理能除去大部分致病细菌，但病毒却去除的很少。目前对病毒的类型检定虽已取得一定进展，但对引起人类和家畜染病的传染性病毒通过水循环，以及在生态系统中，特别是在土壤－植物系统中的迁移、分布和消长规律，还没有比较完善的研究方法。为了防止土壤的生物污染，必须利用一切条件，因地制宜地对污染源进行无害化处理，并加强对病毒在土壤以及生态系统中迁移、分布和消长规律的研究。参考书目D.M.Shicklune, Soil Ecology and EnvironmentalQuality,Soils-An Introduction to Soils and PlantGrowth， 4th ed.， Prentice-Hall Inc., EnglewoodCliffs, New Jersey, 1977.CSIRO,What"sWrongwithMySoil?
