Thermal Desorption Chemical Ionization Mass Spectrometer for Ultrafine Particle Chemical Composition
A wide range aerosol spectrometer (WRAS) was used for comprehensive long term measurements of aerosol size distributions. The system combines the results of an optical aerosol spectrometer with the results of a Scanning Mobility Particle Sizer (SMPS) to record essentially the full size range (5 nm – 32 μm) of atmospheric particles in 72 channels. Measurements were carried out over one year (200...
A brief review on the progress on in vivo studies of α-particle radiation effects using zebrafish embryos was given in this chapter. The zebrafish, Danio rerio, a small vertebrate from Southeast Asia, has become a preferred model for studying human disease. The main challenges of these α-particle radiobiological experiments included quantification of alpha-particle dose. In particular, speciall...
The combined effects of low-dose or high-dose alpha particles and depleted uranium (DU) in Zebrafish (Danio rerio) embryos were studied. Three schemes were examined-(i) [ILUL]: 0.44 mGy alpha-particle dose + 10 µg/l DU exposure, (ii) [IHUH]: 4.4 mGy alpha-particle dose + 100 µg/l DU exposure and (iii) [IHUL]: 4.4 mGy alpha-particle dose + 10 µg/l DU exposure-in which Zebrafish embryos were irra...
