Description: The zinc model is a conceptual tool used in environmental science to analyze and understand the behavior of zinc in ecosystems. This model allows researchers to study how zinc, an essential metal but potentially toxic at high concentrations, interacts with different components of the environment, including soil, water, and living organisms. Through simulations and analyses, the zinc model helps predict the mobility, bioavailability, and ecological impact of this metal, facilitating the identification of risks and the formulation of environmental management strategies. Its relevance lies in the growing concern over heavy metal pollution and the need to assess the effects of these contaminants on ecosystems and human health. This model is based on principles of chemistry, biology, and ecology, integrating empirical and theoretical data to provide a holistic view of the zinc cycle in nature.
