Scope
of Environmental Chemistry
Environmental Chemistry is the study of
chemicals as they pass through our environment and the effects they cause on
the air, water, soil etc. It is an important field of study as it helps us to
trace and control contaminants.
Environmental chemistry is the study
of chemical processes occurring in the environment which are impacted by humankind's
activities. Important general
concepts from chemistry
include understanding chemical reactions
and equations, solutions, units, sampling, and analytical techniques.
Environmental
chemistry plays a major role in environment. Chemical species present in the
environment are either naturally occurring or generated by human activities.
Environmental pollution is the effect of undesirable changes in the surrounding
that have harmful effects on plants, animals and human beings.
Environmental chemistry focuses on the presence and impact of chemicals in soil, surface water,
and groundwater. Environmental
chemists study how chemicals
usually contaminants move through the environment. They also study the effects of these contaminants on
ecosystems, animals, and human health.
Chemical measures of water quality include dissolved oxygen
(DO), chemical oxygen
demand (COD), biochemical oxygen demand (BOD), total dissolved solids (TDS),
pH, nutrients nitrates and phosphorus, heavy metals (including copper, zinc,
cadmium, lead and mercury), and pesticides.
