Environmental chemistry is the branch of science that investigates the origin, mobility, reactions, consequences, and fates of chemical species in the environment. It also examines how we connect with our surroundings on a social, economic, ecological, physiological, and biochemical hierarchy. Furthermore, it combines biology, healthcare, sociology, biochemistry, toxicology, analytical chemistry, organic chemistry, inorganic chemistry, analytical chemistry, and many other broad disciplines.
