Health Hazards of Nanoparticles and Environmental Pollutants
Abstract: The exponential growth in the use of nanoparticles and the prevalence of environmental pollutants have raised significant concerns regarding their health hazards. Nanoparticles, owing to their unique physicochemical properties—such as small size, high surface areatovolume ratio, and chemical reactivity—can penetrate biological barriers, including the bloodbrain barrier, and interact at the cellular and molecular levels. This can lead to oxidative stress, inflammation, and cellular dysfunction, ultimately resulting in potential toxicity. Similarly, …

Adsorption Isotherms for the Removal of Heavy Metals from Aqueous Solution Using Groundnut Shell and Rice Husk
Abstract: Heavy metals are considered as hazardous to the environment due to their toxicity even at low concentration. Batch experiments were conducted to know the potentiality of agricultural byproducts (Groundnut shell, Rice husk and combined adsorbents) on removal of heavy metal ions. It has been found that the percentage of adsorption increases with increase in pH and decreases with the increase in metal ions concentration. The obtained results showed that the …
