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

 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.
