Zinc in the Environment
#Introduction
Zinc is an essential mineral of “exceptional biologic and public
health importance” and is considered a “Life Saving Commodity” by
the United Nations.
Due to its unique properties, zinc is used in a wide range of
consumer, infrastructure, agricultural, and industrial products.
More importantly, zinc is essential to life, playing an important
role in biological processes of all living organisms (humans,
animals, and plants). Zinc is crucial for cell division, protein
synthesis, the immune system and growth.
#Natural Occurrence
Zinc is the 24th most abundant element in the Earth’s crust and has
been present ever since the planet formed its surface. All life on
earth has developed in the presence of zinc.
The concentration of zinc in nature without the additional
influence of human activities (anthropogenic emissions) is called
“natural background.” The natural background levels in surface
water, soil and rock vary over a wide range of concentrations.
Background levels of zinc in soil and rock typically range between
10 and 300 milligrams per kilogram, and zinc in rivers varies from
less than 10 micrograms per liter to over 200 micrograms.
#Zinc Cycling Through Nature
By natural erosion processes, a small part of the zinc in soil,
rock and sediment is constantly moved and transported through the
environment. Rain, snow, ice, solar heat and wind erode
zinc-containing rocks and soil. Wind and water carry minute amounts
of zinc to lakes, rivers and the sea, where it collects as sediment
or is transported further. Natural phenomena such as volcanic
eruptions, forest fires, dust storms and sea spray also contribute
to the continuous cycling of zinc through nature. It is estimated
that these natural emissions of zinc amount to 5.9 million metric
tonnes each year.
Human activities do not add to the overall zinc amount on a global
scale. But mining, production of goods and the use of zinc create
situations where emissions to the atmosphere, soil and water can
occur. These are known as anthropogenic emissions, which are
estimated to be a fraction of the total emissions from the natural
cycling of zinc from erosion, sea spray, volcanic eruptions etc.
Potential sources of anthropogenic zinc emissions include: the
production and processing of zinc into products; emissions from
power plants and other municipal and industrial sources not related
to the zinc industry and; certain zinc applications where corrosion
or abrasion may result in small releases of zinc to the
environment, although these are generally widely dispersive in
nature.
On a global scale, the influence of natural zinc cycling processes
on environmental zinc levels is much more important than the
influence from human activity. However, at a local scale,
anthropogenic emissions can in some places outweigh natural
processes.
