?The aim of this special edition[Present condition of soil pollution and the Soil Contamination Countermeasures Law]Kouji MuraokaDepartment of Cultural Environment, Osaka Sangyo UniversitySoil pollution is one of the seven types of pollution. The Soil Contamination Countermeasures Law, which is the last fundamental law for the measures on prevention of pollution, was enforced in 2002. However, the law on the control of soil pollution to agricultural lands went into effect in 1970. The Water Pollution Control Law, which is closely related to soil pollution, was also enacted in 1970. The environmental standards in soil were defined in 1991. Subsequently, after they were reviewed, the environmental standards on the 27 items were established. Why is the consolidation of the legal system over soil pollution only delayed? The answers to this question are detailed below. ? Certain areas of land are private properties, thus, it is quite difficult for the government to impose laws for the preservation of the quality of the soil, unlike in the case of the protection of water reserves and maintenance of clean air.? In the case of pollution of a private land, the contamination is usually protracted because a public legal system cannot readily meddle in the affairs of the proprietors. A background factor of longstanding soil pollution, which has not been detected, has been present for a considerable time.Under these circumstances, the following reasons on the prompt institution of the legal system on soil contamination are deliberated.? Plant relocation and the change in industrial structure as a new practical use of a previous plant site are becoming an increasing trend.? The momentum on intensive land use of an urban area due to city redevelopment is rising.Consequently, soil pollution, especially in an urban area, has actualized one after another and the cases which indicate soil pollution have increased. In land dealings, the problem on determining the value of real estate situated in polluted land is also raised. Moreover, the expansion of groundwater monitoring has revealed widespread soil pollution. In addition to the recent large scale contamination, such as organic arsenic contamination at Kamisu City in Ibaragi, heavy metal contamination at Osaka Amenity Park in Osaka, the problem of ferrosilite refill materials over Mie, Aichi, and Gifu prefectures, the alarming cases of soil pollution are still observed all over Japan. If it is a fact that soil is polluted by social activity or the immediate living environment then public concern for human health will naturally rise. For instance, the Law Concerning Special Measures Against Dioxin, which was enacted in 2002, has resulted in a mass awakening on the adverse effects of the chemical to ones health. The Soil Contamination Countermeasures Law came to be enacted only after a severe debate on the measures during the government council, such as how investigation should be conducte。省略部分。inst PCB Waste" (June 2001 proclamation). The types of PCB wastes, collection and conveyance, disposal methods, and acceptance standards for the last waste disposal place are stated in " Waste Disposal and Public Cleansing Law (Law No.137 of 1970) " (December 1970 proclamation). This law also places emphasis on the treatment of PCB-polluted soil. Table 1   Environmental standardsRegarding dioxin, the environmental standards on the quality of the atmosphere, water, bottom sediment, and soil are specified based on the “Law Concerning Special Measures against Dioxins”. (refer to Table 1) In addition, the necessary regulation and measure on dioxin-contaminated soil are also stipulated. This law is different from the “Soil Contamination Countermeasures”. Based on the “Law Concerning Special Measures against Dioxins”, three regions are designed as the measured areas against soil contamination in Japan (as of February 2006). The designation at the two regions has already been lifted because the assessment is complete. Moreover, the investigation on soil pollution caused by dioxin is noted in "The Manual of the Survey and Measurement of Dioxins in Soil" (January 2000)2).3. Development of countermeasure technologyIn the existence of soil pollution in a certain area, the person responsible for the contamination and the landowner have the sole task to eradicate the contamination promptly and to ensure the security of the people residing within the vicinity. Therefore, practical application and dissemination of investigation procedures in the event of soil pollution and countermeasure technology, which should be economical and safe, are strongly desired. Especially, as regards PCB and dioxin which are highly toxic and stable chemicals, detailed objective evaluation and technicality of the technology as to the effects of the treatment or the influence of the treatment on the peripheral environment are significant.The Environment Agency (currently, the Ministry of the Environment) demonstrated an investigation 3) on dioxin pollution soil purification technology in 1999. Six technologies (Table 2), such as melt-solidification and chemical decomposition method, etc. were selected. Since 2003, the study on the establishment of technology, which can purify dioxin and PCB, has been conducted. This study resulted in the formation of totally 14 (Table 2) out of the methods on melt-solidification, Thermal Phase Separation (TPS), and steam decomposition. The result is submitted to the Ministry of the Environment HP4)5) and is undergoing development for future investigation of technology to salvage contamination of the environment by PCB or dioxin.Table 2 Technology approved by the Ministry of the Environment for investigation on dioxin-polluted soil purificationFig. 1 Vitrifiction facilities(GeoMelt 100t / batch, 2003, Hashimoto-shi, Wakayama) Fig.2 Thermal Phase Separation facilities(Treatment of dioxin-contaminated soil, 2006, Toyono-gun, Osaka)
