28,703 | Black carbon aerosol output from a photocopier | Schnell, RC; Allen, GA; Hansen, ADA | 1,992 | Summary and conclusions. The impetus for this research was to determine if there was a detectable output of aerosolized toner from an office photocopy machine and a laser printer. We established that this was the case.

42,735 | Alteration in surface structure of Clara cells and pulmonary cytochrome P-450b level in rats exposed to ozone | Suzuki, E; Takahashi, Y; Aida, S; Kimula, Y; Ito, Y; Miura, T | 1,992 | Changes in the surface structure of Clara cells in the terminal bronchioles following exposure of rats to 0.4 ppm ozone (O3) for 14 days were evaluated and compared to the content of pulmonary cytochrome P-450, an enzyme active in xenobiotic metabolism. Exposure to O3 caused a striking alteration of Clara cells in the ... | 0 |
42,386 | Effects of acute exposure to O3 on rats: Sequence of epithelial and inflammatory changes in the distal airways | Bhalla, DK; Young, C | 1,992 | This study involves the analysis of the sequence of changes in lung epithelial permeability,
free cells in the airways, prostaglandin E2 (PC?;J levels, polymorphonuclear
leukocyte (PMN) flux, and alveolar lesions in rats exposed to 0.8 ppm ozone (03 for 3

43,540 | Ozone impacts on seasonal foliage dynamics of young loblolly pine | Stow, TK; Allen, HL; Kress, LW | 1,992 | #Effects of above- and below-ambient levels of ozone (O3) on the production, abscission, and duration of foliage of young loblolly pine (Pinus taeda L.) grown in open-top chambers were examined in the Piedmont of North Carolina. Assessments of fascicle elongation and number were made at frequent intervals during 1988, ... | 0 |
43,212 | Partitioning of biomass and carbohydrates in field-grown radish under ambient concentrations of ozone, and treated with the anti-ozonant ethylene-diurea (EDU) | Kostka-Rick, R; Manning, WJ | 1,992 | The use of an anti-ozonant provides a potential way for assessing yield losses caused by oxidant air pollution, predominantly ozone (O3), in field-grown crops without the need of enclosures like open-top chambers One major prerequisite for the soundness of this method is the absence of direct effects of the anti-ozonan... | 0 |
