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 metal is also transformed into zinc compounds (e.g. zinc
oxide, zinc chloride, zinc phosphate) that are used in a wide
variety of applications. These uses may also result in small
diffusive releases.
During the production and use phase of zinc, zinc compounds with
varying solubility may be formed and be released into the
environment. In addition to these emissions related to human
activity, a natural flow of zinc will always cycle through the
environment due to the natural processes of weathering and erosion.
All these processes mobilize a variety of zinc compounds into the
environment.
Once mobilized, zinc interacts with the different components of
water, sediments and soil and ultimately partitions between
different fractions in these environmental compartments. This
interaction and the dynamic processes involved ultimately define
zinc’s environmental fate, i.e. the form(s) in which the metal will
be present in the environment and in which it will ultimately end
up. In this respect, most of the zinc will return to the stable
chemical form, often ZnS, from which it was originally mined. This
“mineralization” back into stable chemical forms closes the
“cycle.”
The original and ultimate chemical forms of zinc (mainly ZnS) are
very stable, and the contained zinc has very low solubility and
very low potential for uptake by organisms (bioavailability).
