Effects of fine carbonaceous particles containing high and low unpaired electron spin densities on lungs of female mice.
The negative impacts on human health that accompany inhalation of atmospheric particles are documented in numerous epidemiologic studies, but the effect of specific chemical properties of the particles is generally unknown. We developed and employed technology for generating inhalable aerosols of carbonaceous air pollution particles that have specific physical and chemical properties. We find t...
متن کاملCorrelated Microanalysis of Carbonaceous
Introduction: Recent work has shown that sub-micron car-bonaceous spheres (" nanoglobules ") constitute a microstructur-ally distinct, ubiquitous form of extraterrestrial organic carbon. Nanoglobules have been reported to occur in the insoluble organic matter (IOM) of carbonaceous chondrites, in the matrices of primitive chondrites, in interplanetary dust particles and in Wild-2 samples [1-4]. ...
متن کاملCarbonaceous Nanospheres in Chondrites
Introduction: In the 1960s, prior to the widespread use of TEMs, several papers described rounded, micron-sized organic particles from carbonaceous chondrite (CC) meteorites [1-3]. Some of these particles were hollow. Except for two early TEM studies [4, 5], the rounded structures were essentially neglected until similar material was discovered in the Tagish Lake meteorite [6]. We subsequently ...
