Organ burden and pulmonary toxicity of nano-sized copper (II) oxide particles after short-term inhalation exposure
INTRODUCTION Increased use of nanomaterials has raised concerns about the potential for undesirable human health and environmental effects. Releases into the air may occur and, therefore, the inhalation route is of specific interest. Here we tested copper oxide nanoparticles (CuO NPs) after repeated inhalation as hazard data for this material and exposure route is currently lacking for risk ass...
متن کاملSynthesis and Characterization of Nano-Sized Hexagonal and Spherical Nanoparticles of Zinc Oxide
ZnO plays an important role in many semiconductors technological aspects. Here, direct precipitation method was employed for the synthesis of nano-sized hexagonal ZnO particles, which is based on chemical reactions between raw materials used in the experiment. ZnO nanoparticles were synthesized by calcinations of the ZnO precursor precipitates at 250 ˚C for 3hours. ...
متن کاملComparing inhaled ultrafine versus fine zinc oxide particles in healthy adults: a human inhalation study.
RATIONALE Zinc oxide is a common, biologically active constituent of particulate air pollution as well as a workplace toxin. Ultrafine particles (< 0.1 microm diameter) are believed to be more potent than an equal mass of inhaled accumulation mode particles (0.1-1.0 microm diameter). OBJECTIVES We compared exposure-response relationships for respiratory, hematologic, and cardiovascular endpoi...
متن کاملComparison of teratogenecity induced by nano- and micro-sized particles of zinc oxide in cultured mouse embryos
The increasing uses of zinc oxide nanoparticles (nZnO) in industrial and personal care products raise possible danger of using nZnO in human. To determine whether ZnO induces size-dependent anomalies during embryonic organogenesis, mouse embryos on embryonic day 8.5 were cultured for 2 days under 50, 100, and 150 μg of nZnO (< 100 nm) or micro-sized ZnO (mZnO; 80 ± 25 μm), after which the morph...
متن کاملantimicrobial effect of nano-zinc oxide and nano-chitosan particles in dental composite used in orthodontics
background : incidence of white spots due to demineralization of enamel and gingival problems is an unacceptable result of orthodontic treatment. plaque accumulation and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...
