Environmental chemistry is the study of how chemicals interact with the environment. It focuses on understanding the composition, reactions, and effects of various substances in air, water, and soil. By examining pollutants and their sources, scientists can develop strategies to reduce their impact on ecosystems and human health. This field also explores natural processes, such as the carbon cycle and nitrogen cycle, which are essential for maintaining a balanced environment. Environmental chemists work to assess the effects of industrial waste, agricultural runoff, and climate change on our planet, helping to create a cleaner and more sustainable future.
