Environmental Fate of Zinc
Zinc released to the environment follows a cycle (figure 1) in
which zinc from mineral ore bodies is converted through extraction
and refining processes from its mineral state (mostly sphalerite
ore, zinc sulfide) into the metallic state.[5] Most of this metal
will have a long service in stable metal applications and will be
recovered and recycled at the end of life. Metallic zinc that is
exposed to the atmosphere may be subject to corrosion that will
result in a slow release of small amounts of zinc into the
environment.
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.
