A comprehensive view on accumulation of emerging contaminants in soil through sludge and their impact on plants

The utilisation of sewage sludge as well as recycled water in agriculture poses both a potential advantage and difficulty due to the existence of developing pollutants. The contaminants consist of a wide variety of compounds, such as medicines, heavy metals, pesticides, and nanomaterials. These pollutants can build up in soil and have an impact on the growth of plants. This review provides a detailed analysis of the current understanding on the origins, categories, processes of buildup, and consequences of newly identified pollutants in soil. Contaminants infiltrate soil mainly using sludge including reclaimed water, enduring because of their chemical characteristics and relations to soil constituents. Contaminants, when present in soil, can disturb soil microbial populations, modify the process of nutrient cycling, and diminish fertility, so affecting the health of plants. Plants could take in these harmful substances, which can then be passed on to other organisms in the food chain, so endangering human health. The article explores the use of sophisticated wastewater treatment technology and soil supplements as methods to reduce the impact of contaminants in agricultural settings. It also emphasises the importance of implementing strong regulatory frameworks to effectively manage contaminant levels. Potential areas for future research are comprehending the enduring effects on soil health and formulating efficient measures to protect crop yields and environmental sustainability. This analysis emphasises the immediate need for interdisciplinary approaches to mitigate the detrimental effects of emerging contaminants on soil as well as plant systems.
