Abstract
Environmental quality assessments require the determination of concentrations of various substances. This chapter outlines key points for environmental quality analysis. First, environmental standard values (environmental standards and regulation standards) and analytical methods (official methods) are explained. Next, preparation methods for analytical samples are discussed with respect to sampling methods and sample preparation. Samples must be suitable for analysis after preparation. Pretreatment of samples for analysis is discussed in Sect. 6. Analytical values are obtained by the analysis of pretreated samples, and the reliability of the analytical values is described in Sect. 7. Finally, a leaching test, used for waste analysis, is discussed in terms of judgment criteria for landfill waste, environmental quality standards for soil pollution, soil leaching and content standards, and radioactive substance standards.
