| Abstract | This chapter provides an overview of the important physicochemical properties of aqueous and solid environmental matrices. The term aqueous environmental matrix encompasses precipitation, surface water, groundwater, drinking water, wastewater, leachates, sediment pore water, and soil solutions. A solid environmental matrix means soils, sedimentary matter, and waste materials that are not of industrial origin but not minerals and ores. The chapter provides examples on how selected physicochemical properties of samples influence analytical results and their interpretation. The chapter summarizes the important physicochemical properties of environmental matrices under consideration together with references on their determination. The predominant temperature in the sample influences the solubility and stability of analytes in aqueous media as well as other physicochemical properties. Solid environmental samples are heterogeneous in composition and structure and contain considerable amounts of air and water. Temperature measurement can be made with the same equipment as used for aqueous samples though it is necessary to be more cautious to prevent breakage of the thermometer/sensor and to wait longer than in liquid phase for reaching thermal equilibration before recording temperature. |
