8. Physical and Chemical properties of interest
The chapter discusses the physical and chemical properties of environmental quality monitoring, focusing on mass concentration and its significance in various media like air, water, and soil. It elaborates on key concepts like aqueous solubility, vapor pressure, and partition constants, which are crucial for understanding the behavior of chemicals in the environment. The relationship between organic chemicals and soil properties is emphasized, along with the implications for environmental contamination and remediation.

What we have learnt
- Mass concentration is the key quantity of interest in environmental quality monitoring.
- Partition constants are critical in determining the behavior of chemicals between different phases.
- Organic content in soil significantly affects the partitioning of organic chemicals.
Key Concepts
- -- Mass Concentration
- The amount of a substance per unit volume, often expressed as mass per volume (e.g., mg/m³).
- -- Partition Constant
- A ratio that indicates the distribution of a chemical between two phases (e.g., water and soil) at equilibrium.
- -- Aqueous Solubility
- The maximum amount of a substance that can be dissolved in water at a specific temperature and pressure.
- -- Henry's Constant
- A measure of the solubility of a gas in a liquid under equilibrium conditions.
