Carbon quantum dots, the newest class of synthetic nanomaterial’s, have gained attention since they are produced using environmentally friendly chemical processes and organic waste. These nanoparticles are made from biomass, such as fruit peel and other organic materials, and the process produces mixes of CQD species with various chemical identities, levels of activity, and photo physical characteristics. They are typically utilized as a chemically heterogeneous ensemble and have already had an impact on a number of environmental industries; including biomedicine, model agro-fertilizers, wastewater sensors, and switches. An accurate and thorough evaluation of their impact on agriculturally significant crops and produce is required as their applications to crops transition, which is a crucial crossover point. We discuss the knowledge gaps that need to be filled in order to ensure the safe use of CQDs in agronomy as we assess the current state of CQDs in relation to their influence on the biosphere using recent model studies. For human and environmental safety and sustainability, it is essential to have a thorough understanding of their effects on aquatic systems and the food chain
