  • 1. Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in the environment. It involves understanding the sources, reactions, transport, effects, and fates of chemical species in air, water, soil, and living organisms. Environmental chemists strive to identify and quantify pollutants, develop ways to prevent or remediate environmental contamination, and assess the risks posed by various chemicals to human health and ecosystems. By studying the complex interactions between chemicals and the environment, environmental chemistry plays a crucial role in promoting sustainable practices and protecting the health of our planet.
