The study of reactions, origins, transport, effects, and the fates of all chemical species present in the soil, water, and air environments, as well as the influence of technology on them, is referred to as environmental chemistry. The scientific study of biochemical and chemical events that occur in natural settings is known as environmental chemistry. Environmental chemistry is a research field that encompasses more than just air, water, soil, and chemicals. This field employs a variety of methodologies from biology, arithmetic, genetics, engineering, hydrology, toxicology, and other fields to help find answers to all environmental concerns. Environmental chemistry encompasses features of analytical chemistry, physical chemistry, organic chemistry, and inorganic chemistry, as well as a wide range of other disciplines such as epidemiology, public health, biochemistry, biology, and toxicology. Environmental chemists are in charge of figuring out how the unpolluted environment works and developing environmentally friendly methods of development.
Green chemistry, also known as sustainable chemistry, is a branch of chemistry and chemical engineering concerned with the development of products and processes that reduce or eliminate the consumption of harmful compounds. While environmental chemistry focuses on the impacts of polluting chemicals on the environment, green chemistry focuses on chemistry's environmental impact, such as lowering non-renewable resource usage and technological approaches to pollution prevention.
