Bioaerosols suspended in ambient air were collected with single-stage impactors at a semiurban site in southern Germany during late summer and early autumn. Sampling was mostly carried out at a nozzle velocity of 35 m/s, corresponding to a minimum ae

Aerosol matter in the size range o2mm was collected in a Berner impactor and subsequently analysed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectrometry. Owing to the low electron beam energy of 5 keV (occasionally 10 k

Background The Long–Evans cinnamon (LEC) rat has a mutation homologous to the human Wilson's disease gene, leading to copper-induced hepatotoxicity. The mechanism of how excess copper damages the liver or what chemical form of copper is toxic is st

Irradiation of human lymphocytes by alpha-particles under different conditions has been seen to be substantially more effective in the induction of dicentric chromosomes than irradiation by gamma-rays. However, the relative biological effectiveness (

Following the demonstration of morphologic changes induced by a sulphur(IV) aerosol inthe extrapulmonary airways (Takenaka et al., 1990), the pulmonary airways were examined in order to evaluate pulmonary effects. After continuous exposure for 290 da
