Titanium dioxide nanoparticles (TiO2 NPs) are among the highest produced nanoparticles in the world today and are increasingly being incorporated into a wide range of construction and domestic products. Production on such a massive scale raises…

Notwithstanding potential neurotoxicity of Titanium dioxide nanoparticles (TiO2 NPs), the toxicokinetics and consequences on blood brain barrier (BBB) functions remain poorly characterized. We previously described the biodistribution…

The increasing industrial use of nanoparticles (NPs) has raised concern about their impact on human health. Since aging and exposure to environmental factors are linked to the risk for developing pathologies, we address the question of TiO2 NPs…

Due to the growing use of nanoparticles in industrial processes, the number of workers potentially exposed is increasing while the toxicological properties of these compounds are not fully known. Since these particles can be aerosolised, the…

In order to draw appropriate conclusions about the possible adverse biological effects of titanium dioxide nanoparticles (TiO2-NPs), the so-called “dose-effect” relationship must be explored. This requires proper quantification of titanium…

Hexavalent chromium is the most toxic form of chromium. Currently, no biological exposure marker exists that is specific to hexavalent chromium. A bibliographic study has shown that Cr(VI) is incorporated into erythrocytes while the other species…

Notwithstanding the translocation of reported TiO2 nanoparticles (NPs) through biological barriers, the bio-distribution of TiO2NPs to the CNS and impact on the functions of the BBB remain poorly characterized. We report such evidence.
Adult…

Notwithstanding the reported advances in the translocation of titanium dioxide nanoparticles (TiO2 NPs) through biological barriers, the biodistribution of TiO2 NPs to the central nervous system as well as the functional consequences of…

Although workers may be exposed to chromium metal, Cr(III) compounds and Cr(VI) compounds in the workplace, only Cr(VI) compounds are of particular concern in terms of possible health hazards. After uptake via ingestion, inhalation and/or percutaneous…

Beryllium exposure is known to seriously affect health, and even very low levels of exposure may be toxic. It is therefore essential that biological or air-monitoring strategies adopted in the workplace are reliable and accurate over a range…
