PROBLEM TO BE SOLVED: To provide a low-cost and low-environmental-load-type global warming suppression technology for decomposing, insolubilizing, and/or purifying soil polluted by hazardous substances and pollutants such as waste products, and the like, suppressing pollutants at the levels or lower than environmental quality standards for soil over long periods, and naturally adsorbing and decomposing carbon dioxide in air via its reaction step during treatment. SOLUTION: A pollutant treating agent containing non-calcinated peridotite as a principal component is used for separating and/or decomposing pollutants in addition to perform long-term insolubilization by adding and/or mixing light-burned magnesite, light-burned dolomite, fused phosphate, or calcined shell powder according to types of pollutant. Thus, the polluted area is purified. Furthermore, the agent absorbs a large amount of carbon dioxide in air during the step of using the agent, so that the agent has effects as a low-cost and low-environmental-load-type technique for suppressing global warming.
