Zinc in the Environment
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.
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.
