Contaminant transport refers to the movement of chemical substances through various environmental media such as air, water, and soil, driven by physical, chemical, and biological processes. Understanding this phenomenon is crucial for predicting the spread of pollutants and developing strategies for environmental remediation and protection of human health.

Soil is a dynamic natural resource composed of mineral particles, organic matter, water, and air, serving as a medium for plant growth and a habitat for numerous organisms. Its formation and fertility are influenced by factors such as parent material, climate, topography, biological activity, and time, making it a critical component of terrestrial ecosystems and agriculture.

Physical Processes

Chemical processes involve the transformation of substances through chemical reactions, often resulting in the formation of new compounds with distinct properties. These processes are fundamental to numerous industries, including pharmaceuticals, energy, and materials science, and are governed by principles of thermodynamics, kinetics, and reaction mechanisms.

Chemical Processes

Biological processes are the vital sequences of events or chemical reactions that occur within living organisms to sustain life, encompassing everything from cellular respiration to reproduction. These processes are essential for maintaining homeostasis, growth, and adaptation in response to environmental changes.
