“…Although the Derjaguin, Landau, Verwey, and Overbeek theory has generally proved unsatisfactory for the quantitative prediction of colloid behavior in complex natural environments, the conceptual framework that it provides for considering such behavior can be useful in explaining trends in observed behavior in such systems. Some applications of the theory have been made to explain the stability of manufactured NPs in aqueous media [49][50][51].…”

“…Although specific functional coatings may be applied to metal-based NPs during manufacturing, sorption of ions such as humic substances may occur in the environment, potentially involving partial or complete replacement of any manufactured coating. Positively charged Al 2 O 3 NPs (50,80, and 120 nm) demonstrated relatively low mobility [74] because of sorption to negatively charged soil surfaces. Conversely, Al 2 O 3 NPs (50 nm) with adsorbed phosphate, producing a net negative charge, showed reduced sorption to soil and hence higher mobility [73].…”

Abstract-Metal-based nanoparticles (NPs) (e.g., silver, zinc oxide, titanium dioxide, iron oxide) are being widely used in the nanotechnology industry. Because of the release of particles from NP-containing products, it is likely that NPs will enter the soil compartment, especially through land application of sewage sludge derived from wastewater treatment. This review presents an overview of the literature dealing with the fate and effects of metal-based NPs in soil. In the environment, the characteristics of NPs (e.g., size, shape, surface charge) and soil (e.g., pH, ionic strength, organic matter, and clay content) will affect physical and chemical processes, resulting in NP dissolution, agglomeration, and aggregation. The behavior of NPs in soil will control their mobility and their bioavailability to soil organisms. Consequently, exposure characterization in ecotoxicological studies should obtain as much information as possible about dissolution, agglomeration, and aggregation processes. Comparing existing studies is a challenging task, because no standards exist for toxicity tests with NPs. In many cases, the reporting of associated characterization data is sparse, or missing, making it impossible to interpret and explain observed differences in results among studies. Environ. Toxicol.

This study showed the protective role of the phenolic extract of Urtica dioica and silver nanoparticles (AgNPS) on the hepatotoxicity effect via carbon tetrachloride (CCL4) within white male rats. Hundred and ten male albino rats weighing (200-250g) and aged (10-17week). Animals were housed in the animal house of faculty of Science/University of Kufa under control condition; light 12 and 12 dark hours and temperature (24±2C°).Animals divided into four groups as follows the control groups, carbon tetrachloride groups, phenolic extract groups, and silver nanoparticles, groups. Subdivided groups above depending on the concentration (250 and 500mg/kg) of phenolic extract, (10 and 5mg/kg) of silver nanoparticles for (two and three) month add to dosage after and before induced by carbon tetrachloride (five animals per group).The current study revealed the occurrence of a significant decrease (P≤0.05) in the level of regucalcin when the administered by phenolic extract and silver nanoparticles for (two and three months) compared with carbon tetrachloride group. Highly significant (p≤0.05) with the concentration of the (500mg/kg) for phenolic extract and (10mg/kg) for silver nanoparticles, and no significant observed between extract and silver nanoparticles for (two and three months) and before and after induced by the carbon tetrachloride.

In vivo cytogenetical assay in root meristems has been carried out to study the effect of cobalt and cobalt oxide nanos on active mitotic index and chromosomal aberrations of green manure crop, Sesbania pea. Nanoparticles are nanosize particles and can enter freely into the cells and can interfere in cell's normal function. Studies to justify its probable after-effects on living beings are scarce. So it is important to study its effect on living beings. For this purpose, seeds of Sesbania cannabina variety ND-1 were soaked in distilled water for 14 hours and after soaking, the seeds were treated with three different treatments, namely, nanocobalt, nano-cobalt oxide and ethanol for three hours. The treated root meristems exhibited various types of chromosomal aberrations such as metaphasic plate distortion, unorientation at metaphase, breaking of chromosomes, fragmentation, spindle dysfunctioning, stickiness, scattering, precocious movement at metaphase and bridge, unequal separation, multiple bridge, fragmentation, scattering, laggard and unorientation at anaphase, etc.
