Environmental fate is a research area that focuses on understanding the pathways and processes by which contaminants or chemicals move and undergo transformations in the environment. This includes studying the fate of chemicals in air, soil, water, and biota, as well as the factors that influence their persistence, mobility, and ultimately their impact on ecosystems and human health. Researchers in this field use various tools and models to predict and assess the environmental behavior of chemicals, and to inform policies and practices related to environmental protection and management.
