Environmental chemistry is the study of chemical processes occurring in the environment and how they affect living organisms. It focuses on understanding the interactions between natural substances, such as water, air, and soil, and human-made chemicals, like pesticides and pollutants. By examining these interactions, scientists can assess the impact of various substances on ecosystems and public health. This field also plays a crucial role in addressing environmental issues, such as climate change and water quality. Environmental chemists work to develop sustainable solutions, like biodegradable materials and renewable energy sources, to minimize harmful effects and promote a healthier planet for future generations.
