污染土壤的来源及危害性

Sources and hazards of polluted soil

通过文献资料分析、结合典型案例及实际调研的数据,采用类比分析和总结归纳等方法,发现土壤污染主要产生于工业、农业、交通运输及日常生活等领域,主要污染物有重金属、有机物、病原微生物及放射性物质等.污染土壤具有隐蔽性、滞后性、积累性、地域性、不可逆转性和难治理性等特点.污染土壤不仅对人体和动植物的健康及生命造成严重危害,还会影响社会安全生产.我们应提高全民的环保意识,从源头预防土壤污染,加强安全生产并及时治理和修复受污染的土壤.

Analogy analysis and induction methods were applied in study of relevant literature information, typical cases and investigation data of polluted soil. The results show that the main sources of soil pollution come from industry, agriculture, transportation and daily life, and the main pollutants are heavy metals,organics, pathogen microorganism and radioactive substance. Soil pollution is characterized by concealment,hysteresis, accumulation, regionalism, irreversibility and difficult treatment. Polluted soils are not only seriously harmful to the health and life of human beings, animals and plants, but also affect social security. To solve the problem, we should improve people＇s environment awareness, prevent soil pollution from the source, enhance production safety and restore polluted soils timely.
