Global warming has significant effects on the diffusion of heavy metals, altering their distribution and forms in the environment. This review discusses how climate change influences heavy metal movement and its impacts on ecosystems, organisms, and humans. Human activities, such as industrialization and deforestation, have increased greenhouse gas emissions, leading to global warming. This warming affects various environmental factors, including temperature, precipitation, and ocean levels, which in turn influence the movement and transformation of heavy metals in the environment. Heavy metals are released into the atmosphere through industrial emissions, transportation, and fossil fuel combustion, and can be transported and deposited in various environments. Global warming also affects the movement of heavy metals in aquatic ecosystems, increasing their concentrations in lakes and oceans. Additionally, melting glaciers release heavy metals into the ocean, while changes in precipitation and temperature affect the leaching and transport of heavy metals in soils and water bodies. The bioavailability of heavy metals is influenced by factors such as temperature, carbon dioxide levels, and organic matter. Higher temperatures can increase the solubility of heavy metals, making them more available to organisms. Changes in pH and redox conditions also affect the speciation and toxicity of heavy metals. These changes can have adverse effects on aquatic and soil organisms, affecting their growth, development, and survival. Heavy metals can enter the food chain, posing risks to human health. The review highlights the need for further research to understand the complex interactions between climate change and heavy metal pollution, and to develop strategies for mitigating their impacts. The study emphasizes the importance of addressing the environmental and health risks associated with heavy metal contamination under global warming conditions.Global warming has significant effects on the diffusion of heavy metals, altering their distribution and forms in the environment.
