The impact of heavy metal contamination of soils on cereal crops is a matter of increasing concern, representing a significant challenge to global food security and environmental sustainability. As a consequence of their importance as food sources, cereal crops are susceptible to contamination by toxic heavy metals that have been released into the environment as a result of human activities. This article addresses key issues that require extensive research in order to stimulate innovation and gain a deeper understanding of the complex interactions between heavy metals and cereals. Further research is required to develop targeted mitigation strategies and sustainable agricultural practices, given the visible symptoms and physiological changes resulting from heavy metal contamination, such as chlorosis and stunted growth. The formation of root barriers, mycorrhizal symbiosis and metal-binding proteins are emerging as critical defence mechanisms to combat heavy metal stress and provide opportunities to develop metal-resistant cereal varieties. It is of paramount importance to conduct research on metal bioavailability and its implications for food safety in cereal grains in order to protect human health. This paper demonstrates the necessity for interdisciplinary collaboration and cutting-edge technologies to stimulate innovation beyond the state of the art, with the aim of elucidating and mitigating the effects of heavy metals on cereal crops. Genetic and breeding approaches have the potential to facilitate the development of cereal varieties that are more tolerant of heavy metals, while agronomic practices and soil improvements can reduce the bioavailability and toxicity of these metals. The unravelling of the complex mechanisms underlying heavy metal uptake and tolerance is essential for the advancement of sustainable cereal agriculture and food sustainability worldwide. The challenges of heavy metal pollution can be met through proactive research and collaboration, ensuring a resilient future for cereal crops amid changing environmental conditions.
