“…Therefore, the main concern is that NPs can affect different soil horizons, altering physicochemical properties, and organisms ( Pachapur et al., 2016 ). Still, above all, the bio/geo-transformation can be derived ( Rajput et al., 2019 ). It is known that of all transformations, aggregation is the most important, which decides whether NMs behave as aggregates.…”

Both earthworms and terrestrial isopods have been used to evaluate the quality of contaminated soil by NPs. However, most experiments have been conducted in the laboratory and under greenhouse conditions. Besides, little is known of Fe accumulation in earthworms from iron NPs (Fe NPs) under natural conditions. Therefore, the objective of this research was to evaluate the effect of manufactured NPs on the accumulation of Fe in macroinvertebrates from forest soil. Our results revealed that earthworms consume low amounts of Fe in a concentration of 1000 mg Fe NPs kg −1 of dry soil, with a behavior constant over time. Besides, we observed that earthworms could not detect Fe at low concentrations (1 or 10 mg Fe NPs kg −1 ), so they do not limit soil consumption, which translates into high amounts of Fe in their bodies. By contrast, the content of Fe in organisms is inversely proportional to increasing concentrations in the soil (R 2 = -0.41, p < 0.05). Therefore, although studies are needed, in addition to considering environmental factors and the physicochemical properties of the soil, endogenous worms in the evaluated area could, under natural conditions, be useful to inform us of contamination of NP manufactured from Faith. Besides, for future research, a novel methodology should be considered to demonstrate more realistic avoidance behavior under field conditions.

“…However, along with their immense technological potential and opportunities, a discussion has initiated the safety and toxicity risks related to nanomaterials or nanotechnologies. Various studies are being carried out to identify the possible health hazard and toxicity effects of the nanomaterials [77][78][79][80][81]. Therefore, further research should be directed to provide reliable scientific reports to the consumers regarding the benefits, toxicity, and related safety/regulatory perspectives of nanotechnology-based cosmetics products for the actual realization of the scientific inventions.…”

The cosmetics industry has boomed in recent years as one of the markets that holds enormous growth potential. Among several industrial sectors, the cosmetics industry has considered nanotechnology-based principles and implemented in product management practices. Out of 1000 registered products available on the global market, up to 13% were referred to as products for cosmetic use. A large number of nanoscale materials with unique physicochemical properties are currently being used in the cosmetics formulations or recommended for future use as nano-systems or novel nanocarriers to encapsulate active ingredients for their efficient delivery through the skin barriers. These nano-systems have demonstrated potential in targeted-oriented drug delivery and offered remarkable features such as better stability, site-specificity, excellent encapsulation efficiency, prolonged action, enhanced skin penetration, and high drug-loading capability. Nevertheless, nanotoxicology research has raised concerns over the excessive use of nanomaterials/nanoparticles in cosmetics, as nanoparticles might enter the skin resulting in health problems. This review provides insights on the characteristic physicochemical features and the potential use of various nanostructured materials, including liposomes, noisome, nanoemulsions, nanoparticles, carbon nanomaterials (graphene, fullerenes), carbon nanotubes, dendrimers, and nanospheres in cosmeceuticals. Moreover, the regulatory aspects of nanomaterials in cosmetics, along with concluding remarks and outlook in this field, were also vetted.

“…Toxicological concerns exist also for copper and copper oxide nanoparticles as studies indicate a strong relation between decreasing nanoparticles size and increasing phytotoxicity [ 271 , 272 , 273 ]. Some recent studies also indicate effects on plastids, mitochondria, protoplasm, and membranes for Hordeum sativum distichum [ 274 ] or Abelmoschus esculentus [ 275 ].…”

This review presents a perspective on the research trends and solutions from recent years in the domain of antimicrobial packaging materials. The antibacterial, antifungal, and antioxidant activities can be induced by the main polymer used for packaging or by addition of various components from natural agents (bacteriocins, essential oils, natural extracts, etc.) to synthetic agents, both organic and inorganic (Ag, ZnO, TiO2 nanoparticles, synthetic antibiotics etc.). The general trend for the packaging evolution is from the inert and polluting plastic waste to the antimicrobial active, biodegradable or edible, biopolymer film packaging. Like in many domains this transition is an evolution rather than a revolution, and changes are coming in small steps. Changing the public perception and industry focus on the antimicrobial packaging solutions will enhance the shelf life and provide healthier food, thus diminishing the waste of agricultural resources, but will also reduce the plastic pollution generated by humankind as most new polymers used for packaging are from renewable sources and are biodegradable. Polysaccharides (like chitosan, cellulose and derivatives, starch etc.), lipids and proteins (from vegetal or animal origin), and some other specific biopolymers (like polylactic acid or polyvinyl alcohol) have been used as single component or in blends to obtain antimicrobial packaging materials. Where the package’s antimicrobial and antioxidant activities need a larger spectrum or a boost, certain active substances are embedded, encapsulated, coated, grafted into or onto the polymeric film. This review tries to cover the latest updates on the antimicrobial packaging, edible or not, using as support traditional and new polymers, with emphasis on natural compounds.
