Airway responses to nitrogen dioxide in asthmatic subjects
Mohsenin, V
1,987
Nitrogen dioxide is a common indoor air pollutant. In order to characterize the respiratory responses to this gas, 10 asthmatics (mean age +/- SD = 30 +/- 8 yrs) were exposed to air and 0.5 ppm NO2 gas for 1 h in a 30-m3 environmental chamber on different days in a double-blind randomized fashion. The forced vital capa...

Dry deposition of nitrate, ammonium and sulfate to a Ceanothus crassifolius canopy and surrogate surfaces
Bytnerowicz, A; Miller, PR; Olszyk, DM
1,987
Deposition of nitrate (NO3-) ammonium (NH+4) and sulfate (SO2-4 ) to the foliage of' Ceanothus crassifolius and surrogate surfaces was studied in she San Dimas Experimental Forest, 35 km northeast of central Los Angeles. Deposition fluxes of NO-3, and NH+4 to the foliage were found to be well correlated with deposition...

Open pollinated families of loblolly pine differing in resistance to fusiform rust disease were screened in laboratory studies for responses to gaseous air pollutants. Twenty families were given acute exposures (2 fumigations for 4 h each) to SO(2) (0.4-1.0 ppm), O(3) (0.25 ppm), SO(2) (0.4-1.0 ppm) + O(3) (0.25 ppm) a...

The impact of ozone on assimilate partitioning in plants: a review
Cooley, DR; Manning, WJ
1,987
Numerous studies have shown that ozone (O3) reduces plant growth and changes assimilate partitioning. The pattern of such changes varies with species, but trends suggest a comprehensive model. O3 generally reduces the amount of dry matter in the whole plant. In plants which have not flowered or set fruit, and at low O3...
