Over the last few decades, engineering nanomaterials (ENMs) have been incorporated into a variety of commercially-available consumer products (CPs). Silver Nanoparticles (AgNP ( are the most used ENMs in CPs, mainly due to their antibacterial properties. To better understand the fate, transport, and environmental impacts of AgNPs, many studies have been conducted. However, this research has been focused mainly on pristine AgNPs either lab-synthesized or purchased commercially. While these studies have contributed greatly to a better understanding of AgNP toxicology, they have not addressed the environmental concerns associated with AgNP release from CPs. This review assesses previously published work on routes of environmental exposure, characterization techniques, potential ecological risks of AgNPs, and the identification of available toxicity assays for AgNPs in CPs. A major objective of this review is to summarize and identify key issues, knowledge gaps, and potential directions for future research related to AgNPs released from CPs.

“…Nowadays, silver nanoparticles (AgNPs) have attracted great attention due to the wide range of their applications in health electronics, biotechnology, cosmetics, toy production, and clothing (Beyene et al, 2017;Radwan et al, 2021). It has been estimated that 63 tons of AgNPs per year globally enter water bodies (Keller et al, 2013).…”

The unique behavior of silver nanoparticles (AgNPs) led to their increasing use in a wide range of products and high discharge of these particles in the aquatic ecosystem. Regarding little information about the toxicity of AgNPs in the aquatic environment, the prediction of possible environmental hazards is the hot topic of current research studies. This study aimed to investigate the effects of long-time exposure of Asian seabass (Lates calcarifer)‎ to green (using brown macroalga extract) and chemical synthesized ‎AgNPs on oxidant/antioxidant and immunological responses. The LC50 of both synthesized AgNPs was determined after 96 h (LC50 for green synthesize AgNPs= 18.27 mg/l and for chemical synthesize AgNPs= 1.32 mg/l). Fish were exposed to green and chemical synthesized AgNPs concentrations of 0% LC50 (control), 5% LC50 , 10% LC50, and 25% LC50 for 60 days. Fish were sampled at 1, 30, and 60 days after exposure. The liver tissue of fish samples was isolated and homogenized and then the activity of catalase (CAT), superoxide dismutase (SOD) and glutathione (GSH), and malondialdehyde (MDA) was determined. The complement pathway activity (ACP), total immunoglobulin (Ig), total protein, albumin (ALB) ‎concentration, and globulin (GLO) were measured in fish blood samples. The results showed that green synthesized ‎AgNPs first ‎increased the activity of the antioxidant system and then significantly reduced its activity. However, after exposure to chemical synthesized AgNPs, ‎the activity of the antioxidant system showed a significant decrease. Both green and ‎chemical synthesized AgNP exposure caused an increase in proinflammatory activities and ‎immune proteins, and these activities were more ‎pronounced after exposure to green synthesized AgNP.

“…Nanoscale airborne particles from natural or manufactured sources are abundant in our environment. Although manufactured nanoparticles have been used in many fields, they may also endanger human health due to their potential toxicity [1][2][3]. On the scale of nanoparticles, it can be compared with viruses or molecules scale.…”

Knowing particle penetration efficiencies and concentration distributions in an inlet channel of a sampling device is beneficial for the robust assessment, attribution and quantification of nanoparticles produced by various activities. The aim of this research is to evaluate the effect of the presence or absence of a conical column inside a hollow tapered cylinder on the nanoparticle penetration efficiency and its outlet concentration profile for different flow rates. The particle penetration characteristics of various sizes from 3 nm to 20 nm were numerically investigated by using the flow field and convection diffusion equations within the hollow tapered cylinder. Firstly, the proposed model of the nanoparticle penetration efficiency for the hollow tapered cylinder with the conical column is validated with the experimental data in the literature. Then, the results indicate that the concentration at the outlet of the hollow tapered cylinder with the conical column exhibits annular profiles for 3 nm and 5 nm nanoparticles at a flow rate of 2.0 L/min, which is found to avoid centralizing the particles in the exit area. In addition, the penetration efficiency of nanoparticles can be improved by increasing flow rates or removing the conical column inside the hollow tapered cylinder. Finally, the ring-shaped concentration profile of the 10 nm nanoparticles at the outlet of the hollow conical cylinder with the conical column becomes more obvious as the flow rate decreases. This study interprets and quantitatively decides the nanoparticle penetration efficiency and its exit concentration profile for the hollow tapered cylinder with or without the conical column. Therefore, the results can provide some useful design references for the transport of nanoparticles in the hollow tapered cylinder.
