Soil Contamination: A Menace to Life

Abstract

The dire concern for soil contamination includes the safety of food, ecological environment, public’s health and capacity of social sustainable development. Soil is polluted by heavy metals and pesticides which are far beyond pollution standards. The soil biodiversity and agricultural sustainability are adversely affected in long-term harmful effects by the prolonged intensive and indiscriminate use of agrochemicals. It needs immediate attention for the whole world to curb continual deterioration of soil pollution and remediate contaminated soil as soon as possible to decrease harm on people’s health and ecological environment. In fact, acceleration of related legislation, increased capital investment and technical development to remediate soil contamination and must achieve some progress. However, due to all sorts of the constraints, whether soil management system or technical capacity for decontamination is relatively outdated, so there remains a lot of work need to be done. Developing countries, including Brazil, India and so on, are also facing similar problems. Approaches to solve soil problems could benefit developing countries in process of industrialization and urbanization, so it’s a very meaningful job to deep analyze and study the current situation and countermeasures soil pollution. In this Chapter, the overall situation of soil pollution is introduced, the concrete causes and hazards of soil contamination are discussed, and technologies and processes of soil remediation are suggested for improvement of the status of soil contamination and social sustainable capacity.
