“…Titanium oxide (TiO 2 ) and zinc oxide (ZnO) nano-particles (NPs) are some reported semi-conductors having potential effect against heavy-metal water contamination removal [79]. It is reported earlier that, toxic heavy metal can be decontaminated from waste water with Cu, Ag and Fe-induced NPs [98,99]. Nanobioremediation is also a low-cost method for pollution reduction in water and soil.…”

Foods and beverages with heavy metal contents, their Maximum Permissible Limits (MPL), Estimated Dietary Intake (EDI), Target Hazard Quotient (THQ) to study carcinogenic effects with other human health related matters and metal remediation’s are high priority issues for sustainable world-wide developments. Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), Inductively Coupled Plasma-Mass Spectrometer (ICP-MS), Flame atomic absorption spectroscopy (FAAS), Total Reflection X-Ray Fluorescence (TRXF) Spectroscopy, Chemical Replacement Combined with Surface-Enhanced Laser-Induced Breakdown Spectroscopy (CR-SENLIBS), Electrochemical apt- sensors are some advanced monitoring tactics for heavy metal detection. Nanotechnology innovations, soil state-of art remediation are used now-a-days for removal of metals from foods and beverages. In addition to this, chelating ligands, plant phenolic have crucial applications in heavy metal removal from foods. Bio-absorbents like microbial cultures, fermentation wastes also play crucial role in heavy metal remediation from foods and beverages. In the present chapter various metal monitoring tactics are focused with advance metal remediation procedures associated with food and beverages. Limitations of various metals associated with human health risks are also summarized herein.

“…Nanoparticles of hybrid metallic Cu, Ag and Fe are used for antibacterial activity and de-contamination of toxic metal ions in the water system. In addition, water treatment of effluents from textile and tanning industries was leveraged on such nanoparticles or other multifunctional nanoparticles [ 64 ]. Another work on chromium ions elimination from wastewater was also used the adsorption method by titanium dioxide, activated carbon with metal fabrication, alumina, zeolites and in some studies, the reduction of Cr(III) is followed thereafter [ 65 ].…”

Nanotechnology finds its application almost in every field of science and technology. At the same time, it also helps to find the solution to various environment-related problems, especially water contamination. Nanomaterials have many advantages over conventional materials, such as high surface area, both polar and non-polar chemistries, controlled and size-tunable, easier biodegradation, which made them ideal candidates for water and environmental remediation as well. Herein, applications of non-carbon nanomaterials, such as layered double hydroxides, iron oxide magnetite nanoparticles, nano-polymer composites, metal oxide nanomaterials and nanomembranes/fibers in heavy metal contaminated water and environmental remediation are reviewed. These non-carbon nanomaterials, due to their tunable unique chemistry and small size have greater potentials for water and environmental remediation applications.

“…Nanoscale zero‐valent iron is effective in removing classes of pollutants like bacteria, metals, and organic compounds. The instability of iron in the zero‐oxidation state causes it to be very effective as a reducing agent (Holba et al 2013) Although Ag NPs raise some toxicity concerns, there are also applications in wastewater treatment (Daniel et al 2014).…”
