Titanium Dioxide Nanoparticles as an Environmental Sanitizing Agent

Titanium Dioxide Nanoparticles As Guardian against Environmental Carcinogen Benzo[alpha]Pyrene

Polycyclic aromatic hydrocarbons (PAH), like Benzo[alpha]Pyrene (BaP) are known to cause a number of toxic manifestations including lung cancer. As Titanium dioxide Nanoparticles (TiO2 NPs) have recently been shown to adsorb a number of PAHs from soil and water, we investigated whether TiO2 NPs could provide protection against the BaP induced toxicity in biological system. A549 cells when co-ex...

Titanium dioxide: environmental white knight?

T itanium dioxide (TiO 2) is a multi-faceted compound. It's the stuff that makes toothpaste white and paint opaque. TiO 2 is also a potent photocatalyst that can break down almost any organic compound, and a number of companies are seeking to capitalize on TiO 2 's reactivity by developing a wide range of environmentally beneficial products. During the late 1970s, scientists began to realize th...

Manganese Oxide-Surface Modified Titanium(IV) Dioxide as Environmental Catalyst

The purpose of this study is to present an “environmental catalyst” possessing both thermocatalytic activity and visible-light activity for the decomposition of organic pollutants. Molecule-sized MnOx clusters are highly dispersed on the surface of TiO2 (anatase/rutile = 4/1 w/w, P-25, Degussa) by the chemisorption-calcination cycle technique using Mn(acac)3 complex as a precursor (MnOx/TiO2). ...

[Titanium dioxide nanoparticles: occupational exposure limits].

Titanium dioxide (TiO2) is produced in Poland as a high production volume chemical (HPVC). It is used mainly as a pigment for paints and coatings, plastics, paper, and also as additives to food and pharmaceuticals. Titanium dioxide nanoparticles are increasingly applied in cosmetics, textiles and plastics as the ultraviolet light blocker. This contributes to a growing occupational exposure to T...
