Environmental Chemistry

Environmental chemistry is the branch of chemistry that deals with the scientific analysis of the biological and chemical processes occurring in the environment.

It is concerned with the chemicals and other contaminants found in the environment as a consequence of human activity.

  • The study of the sources, transport, interactions, effects, and fates of chemical species in water, air, land, and biological environments is known as environmental chemistry.
  • It deals with the chemical balance in natural systems and how anthropogenic activities disrupt this chemical balance by releasing chemicals into the environment, which changes the natural ecosystem levels.
  • Environmental chemistry is vital to society because it is linked to environmental effects, pollutants, environmental management, and contamination reduction.
  • It combines organic chemistry, analytical chemistry, physical chemistry, photochemistry, geochemistry, and biological chemistry, as well as many other fields such as physics, life sciences, agricultural sciences, medical sciences, public health, and sanitary engineering.
  • Environmental chemistry is socially significant since it deals with the environmental impact of pollutants, contamination reduction, and environmental management.
  • Environmental Chemistry thoroughly investigates the risk factors of all chemicals to provide a solution for environmental safety.
  • It is used to investigate new products and their environmental impact.
  • Environmental chemistry is used to safeguard groundwater that has been polluted by dirt, dust, and waste particles. It is also used in waste management and cleaner production.
  • Environmental chemistry is a research subject that uses approaches from biology, arithmetic, genetics, toxicology, and other disciplines to help find solutions to all environmental challenges.
  • Astrochemistry, atmospheric chemistry, environmental modeling, geochemistry, marine chemistry, and pollution prevention are some examples of the subjects covered by environmental chemistry.
  • Environmental chemistry aims to comprehend the chemical reactions and processes that govern environmental systems, as well as how anthropogenic substances affect them. This method permits environmental chemistry to be constructive rather than reactive.
  • Environmental chemistry also helps to understand how chemicals flow through the environment and their impact on human health and the ecosystem.
  • It also deals with the behavior of pollutants and their environmental consequences on air, water, and soil environments, as well as the effects on human health and the natural environment.
  • Environmental chemistry roles include analyzing air, water, and soil pollution, providing assessment reports, assisting in the improvement of production processes, and developing remediation programs.
  • As environmental chemistry is a more specialized topic of study, course offerings are rigorously developed to present students with both general fundamentals and advanced concepts. There are various programs in the field of environmental chemistry some includes:
    • Stratostropic chemistry
    • Greenhouse effects
    • Chronic toxicity.
    • Spectroscopy and remote sensing
    • Ozone holes
    • Tropospheric chemistry
    • Particles and Air warp-up
    • Environmental pollutions
