ENVIRONMENTAL CHEMISTRY DEFINTION Environmental Chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic and soil chemistry, as well as heavily relying on analytical chemistry and being related to environmental and other areas of science. Environmental chemistry involves first understanding how the uncontaminated environment works, which chemicals in what concentrations are present naturally, and with what effects. Without this it would be impossible to accurately study the effects humans have on the environment through the release of chemicals. CHEMISTRY & THE HYDROSPHERE Hydrochemistry deals with the chemical characteristics and uses of the water on and beneath the surface of the Earth CHEMISTRY & THE ATMOSPHERE Atmospheric Chemistry deals with the different chemical reactions, processes and species not only of the Earth’s atmosphere but also other planet’s atmosphere AIR POLLUTANTS Primary Particles • Pollen • Dust • Fly ash • Polycyclic aromatic hydrocarbons Secondary Particles (formed from gas reactions) • Smog particles • Sulfuric acid droplets • Salts such as (NH4)2SO4 Inorganic Gases • O3 • SO2 • NO • NO2 • CO • H2S • HCl • NH3 Organics • Hydrocarbons including those that form photochemical smog • Odorous organic sulfur compounds • Organohalides • Amines and other organonitrogen compounds • Organo-oxygen compounds including aldehydes and ketones Photochemical Smog • Smog particles • Ozone • Organic oxidants (PAN) • Aldehydes CHEMISTRY & THE GEOSPHERE Geochemistry deals with chemical species, reactions, and processes in the geosphere and their interactions with the atmosphere and hydrosphere. CHEMISTRY & THE BIOSPHERE The Chemistry of the Biosphere deals with the different chemical reactions, processes, and species in the Biosphere and its effect on the Biosphere’s inhabitants A Major Concern Regarding the Biosphere is the Effect of Toxic Substances on Organisms: Addressed by Toxicological Chemistry THE ANTHROSPHERE CHEMISTRY & THE ANTHROSPHERE RELATED CHEMISTIES RELATED TO ENVIRONMENT CHEMISTRY INDUSTRIAL ECOLOGY Industrial ecology views an industrial system as an artificial ecosystem, with primary sources of raw materials and energy and with a number of enterprises making use of what would otherwise be waste products of other members of the system practiced in a manner that minimizes environmental impact while optimizing utilization of resources, energy, and capital. It is All About SUSTAINABILITY; Let’s leave Earth in a Condition to Support Future Generations.
