The major assignments of this project were to collect and analyze the effects and potential problems of the current Soil Pollution Control Standards, compile the regulation strategies of soil pollution in developed countries, research and amend the protocol of zoning management and classification of control standards, and estimate the following influences after executing the protocol.
Since “Soil and Groundwater Pollution Remediation Act” was promulgated, there had been totally 2,296 pollution sites listed nationwide (about 1,189 ha.), some of them have been delisted after improvement and remediation, and presently there are 657 pollution sites listed nationwide (about 789 ha.). All circles have doubted the current Soil Pollution Control Standards as follows: the soil pollution control without adopting zoning standards (except for agricultural land), the different considerations between total concentration and extracted concentration (bioavailability) of a pollutant, the health risk assessment program for amending standards, the suitability of the controlled items and values, etc.
In the process of revising protocol, this project compiled the legal framework, regulation strategies and control measures of soil pollution from 20 developed countries, such as United States of America, Canada, England, the Netherlands, Australia, Japan, etc. Furthermore, this project reviewed the indigenous research literature, considered the problems of present control methods, and collected the comments from various circles during 6 symposiums.
In the contents of this protocol, the proposed Soil Pollution Control Standards established the regulation respectively for three categories of land use including “Sensitive Area,” “General Area” and “Specific Industrial Area”. In principle, the controlled items and values were consulted with the current Soil Pollution Control Standards, but further considered the toxicity, environmental fate and distribution, exposure risks and recommended values of soil pollutants. In the final section, this project estimated the following influences of administration management and economic cost in execution of the protocol, and drew up the adaptive strategies accordingly.
