Environmental Chemistry

Environmental Chemistry is the study of the chemical processes occurring in the environment and the effects of human activities on these processes. It encompasses the investigation of pollutants, their sources, transformations, and impacts on ecosystems and human health. This field integrates concepts from various scientific disciplines, including chemistry, biology, and geology, to understand how chemicals interact within air, water, and soil components. By examining the behavior of substances in natural settings, environmental chemistry aims to develop strategies for pollution prevention and remediation, thereby supporting sustainable practices and environmental protection.
