“…Recalcitrant pollutants, such as volatile organic compounds, heavy metals, pesticides, hydrocarbons, persistent organic pollutants, solvents, dyes, and plastics, can pose adverse effects on health [ 1 , 2 , 3 , 4 ]. Anthropogenic activities such as smelting, mining, fossil fuel refining, the application of agrochemicals, and the disposal of municipal wastes are the primary causes of the accumulation of heavy metals in soils and other environmental compartments [ 5 , 6 , 7 ]. Heavy metal contamination determines significant modifications to soil processes [ 8 ], the microbial community [ 9 ], plants [ 10 ], and animals [ 11 ].…”

Contamination of soil with heavy metals has become a matter of global importance due to its impact on agriculture, environmental integrity, and therefore human health and safety. Several microbial strains isolated from soil contaminated by long-term chemical and petrochemical activities were found to manifest various levels of tolerance to Cr, Pb, and Zn, out of which Bacillus marisflavi and Trichoderma longibrachiatum exhibited above-moderate tolerance. The concentrations of target heavy metals before and after bioremediation were determined using electrochemical screen-printed electrodes (SPE) modified with different nanomaterials. The morpho-structural SEM/EDX analyses confirmed the presence of metal ions on the surface of the cell, with metal uptake being mediated by biosorption with hydroxyl, carboxyl, and amino groups as per FTIR observations. T. longibrachiatum was observed to pose a higher bioremediation potential compared to B. marisflavi, removing 87% of Cr and 67% of Zn, respectively. Conversely, B. marisflavi removed 86% of Pb from the solution, compared to 48% by T. longibrachiatum. Therefore, the fungal strain T. longibrachiatum could represent a viable option for Cr and Zn bioremediation strategies, whereas the bacterial strain B. marisflavi may be used in Pb bioremediation applications.

The escalation of environmental pollution by heavy metals has emerged as a global concern in recent years, posing a significant threat to public health. This phenomenon is exacerbated by the ongoing rise in anthropogenic activities, notably industrial processes and urbanization, which indiscriminately release pollutants into the environment without effective control and mitigation measures. Subsequently, these metals traverse the food chain, impacting animals and humans. Elevated levels of heavy metals can have deleterious effects on organisms and plants, disrupting the metabolic functions of vital organs and glands. Continuous assessment and monitoring of heavy metal levels in the environment are imperative due to the escalating anthropogenic activities. The primary objective of this chapter is to provide an illustrative discussion on important heavy metals, environmental pollution caused by heavy metals, encompassing air, soil, and water. Various toxic effects on human health have been considered, and corresponding remedies have been presented.
