Zinc is a natural element playing an essential role in the biological processes of all humans, animals, and plants.

Zinc is Natural

Zinc is the 24th most abundant element in the Earth’s crust and has been present since the formation of earth. All life on earth is developed in the presence of zinc. Through natural erosion processes, a small part of the zinc in soil, rock and sediment is constantly moved and transported through the environment. 

Zinc is Essential

Zinc is essential to life, playing an important role in biological processes of all living organisms crucial for cell division, protein synthesis, the immune system and growth. Zinc is an essential mineral of “exceptional biologic and public health importance” considered a “Life Saving Commodity” by the United Nations. 

Zinc Fate and Effects

Zinc bioavailability depends on complex interactions with the environment.  To understand these interactions, the zinc industry supports research to develop tools that help scientists predict zinc bioavailability in different environmental conditions and matrices.

The environmental assessment of zinc requires a science-based approach because of its natural occurrence, essentiality to all living organisms, and influences on bioavailability. The distribution, transport and effects of zinc  depend specific characteristics of the environment and factor into such assessments.

Influences and interactions on the distribution, transport, and effects of zinc in nature.

Zinc’s bioavailability (or presence in a form that is available for uptake by organisms) is determined by complex interactions with the environment and is strongly dependent on the characteristics of that environment. Studies using state-of-the-science approaches have concluded that current zinc uses contribute negligible amounts of bioavailable zinc to the environment and therefore have low potential for environmental effects
