Impact of Emerging Contaminant on Farmland Soil

The global focus on emerging contaminants is justified because of their harmful impact on human health and the urgent need to establish regulatory standards. The quantification of certain emerging contaminants in worldwide soil is measured in metric tons; however, Identifying the source of these contaminants in soil environments is difficult because of the diverse nature of the medium and the complex mechanisms involved in their interactions. Most emerging contaminants demonstrate a heightened affinity for solid matrices and tend to adhere to them. These emerging contaminants not only disrupt the functionality of soil but also impact plants and animals. The toxicity of these contaminants can be observed in cell cultures and animals within a range spanning from nmol to mmol. These substances tend to accumulate in root-based food crops, posing a potential threat to human health. The lack of a thorough understanding regarding the fate of certain emerging contaminants in anaerobic environments and their pathways within the food web hinders the development of effective bioremediation strategies, the restoration of polluted soils, and the support for global regulatory initiatives. Despite the established harmful effects of these contaminants on living organisms, there are currently no specific environmental laws or guidelines in place to address them. Additionally, available information concerning the impact of soil pollution from emerging contaminants on human health remains incomplete. Therefore, we present a comprehensive explanation of several notably significant emerging contaminants, specifically: PFAS, micro/nanoplastics, additives (biphenyls, phthalates), flame retardants, and nanoparticles. Our focus centers on quantifying the burden of contaminants in soil and examining the resultant repercussions.
