About this Research Topic
Nanotechnology and nanoscience have been used to design and synthesize engineered nanomaterials (ENMs) to face different human and environmental issues. ENMs with novel properties and characteristics have intentionally been delivered to the environment to decontaminate polluted sites. Several technologies regarding nanoremediation such as phytonanoremediation, bionanoremediation, or electronanoremediation highlight the potential of the ENMs to degrade, dissipate, or adsorb hazardous compounds. Smart materials, nanomachines, bionanomaterials, nanobiohybrids, among other nanosized materials, have been used in nanoremediation strategies. These newly created technologies have better dissipation and/or degradation rates than traditional technologies for remediation. However, these emerging technologies merit special attention with respect to their potential environmental risk. So far, neither ENMs nor the nanotechnologies to recover contaminated sites are subject to any special regulation. Aside from the effects of nanoremediation on target systems, its collateral consequences have been scarcely evaluated, i.e., this field of research is still fledgling, and its advantages and drawbacks have not been fully described yet.
This Research Topic frames and highlights nanosized engineered materials' applicability to recover and decontaminate polluted sites such as soil and water, or air. New nanomaterials, procedures, devices, and experimental designs have been carried out to understand and increase the dissipation rate of ubiquitous and recalcitrant pollutants. Therefore, the direct and collateral effects should be reported to know the potential advantages and the hidden drawbacks of nanoremediation to shape a secure and economical way of recovering degraded sites and, consequently, improve environmental services.
Contributions should be related to the efficacy of remediation, degradation rate, and toxicity of engineered nanomaterials used to recover degraded sites. The use of nanomaterials in conjunction with live organisms such as plants, microorganisms, or earthworms, is especially welcome.
