43,588 | Yield and quality of spring barley, Hordeum vulgare L, exposed to different concentrations of ozone in open-top chambers | Pleijel, H; Skarby, L; Ojanpera, K; Sellden, G | 1,992 | Spring barley (Hordeum vulgare L., cv. Lina) was exposed to different concentrations of ozone in open-top chambers (OTCs) for 6 weeks following anthesis at a site located in south-west Sweden during the summer of 1989. The chambers were placed in a field of commercially grown barley. The treatments were charcoal-filter... | 0 |
625,299 | Oxidative damage to plasma constituents by ozone | Cross, CE; Motchnik, PA; Bruener, BA; Jones, DA; Kaur, H; Ames, BN; Halliwell, B | 1,992 | The reaction of ozone (O3) with human blood plasma was studied to help understand possible events that could occur in the respiratory tract. Uric acid (quantitatively the most important scavenger) and ascorbic acid were oxidized quickly, protein-SH groups were lost more slowly, and there was no loss of bilirubin or alp... | 1 |

11,876 | Air pollution and short-term health effects in an industrialized area in Norway Estimating individual air pollution exposure | Clench-Aas, J; Harstad, A; Aarnes, MJ; Bartonova, A; Braathen, OA; Gronskei, KE; Hagen, LO | 1,992 | Norwegian Ministry of the Environment; Norwegian State Pollution Control Authority. SUMMARY: The Ministry of the Environment and the Norwegian State Pollution Control Authority initiated in 1988 an investigation of the short term health effects of air pollution in Grenland, an industrialized area of Norway. A cohort s... | 0 |
43,259 | Nonlinear regression with variance components: Modeling effects of ozone on crop yield | Gumpertz, ML; Rawlings, JO | 1,992 | Split-plot experimental designs are common in studies of the effects of air pollutants on crop yields. Nonlinear functions such as the Weibull function have been used extensively to model the effect of ozone (O3) exposure on yield of several crop species. The usual nonlinear regression model, which assumes independent ... | 1 |
91,442 | Estimating the total value of forest quality in high-elevation spruce-fir forests | Haefele, M; Kramer, RA; Holmes, TP | 1,992 | The protection of forest resources is currently one of the most important policy issues in the U.S. This paper reports the results of a study to determine the nonmarket benefits of protecting forest quality in the southern Appalachian Mountains. The contingent valuation method is used to estimate the total value of for... | 0 |
42,725 | How far does ozone penetrate into the pulmonary air/tissue boundary before it reacts? | Pryor, WA | 1,992 | A simple method is suggested for calculating the time it takes ozone to traverse a biological region, such as a bilayer or a cell, and comparing this time to the halflife of ozone within that region. For a bilayer the calculations suggest that most of the ozone reacts within a bilayer, but a fraction may exit unreacted... | 1 |
14,586 | Global change at the local level: assessing the vulnerability of vertebrate species to climatic warming | Herman, TB; Scott, FW | 1,992 | We present an approach for analyzing vulnerability of terrestrial and aquatic vertebrates in Nova Scotia to climatic warming. Most global circulation models predict decreased summer precipitation, increased winter precipitation (especially rainfall) and higher average winter temperatures in this region. We adapted the ... | 0 |

47,551 | Structure of stratospheric intrusions into the troposphere | Appenzeller, C; Davies, HC | 1,992 | SUMMARY. FLOW phenomena that link the stratosphere and the troposphere are a key component of mid-latitude weather systems1, and can influence substantially the distribution of atmospheric gases and aerosols2,3. Little is known, however, about the detailed structure of these features. Here we combine satellite measur... | 0 |
37,941 | Effect of nitric acid vapor on the response to inhaled ozone | Nadziejko, CE; Nansen, L; Mannix, RC; Kleinman, MT; Phalen, RF | 1,992 | Studies concerned with the adverse health effects of acidic atmospheres have focused primarily on sulfuric acid aerosols and other acid sulfates. Little information is available on the health effects of nitric acid (HNO3), an important atmospheric pollutant in southern California. The purpose of this study was to inves... | 0 |
42,762 | Attenuation of ozone-induced airway permeability in rats by pretreatment with cyclophosphamide, FPL 55712, and indomethacin | Bhalla, DK; Daniels, DS; Luu, NT | 1,992 | Exposure of rats to ozone (O3) produces an increase in airway permeability and a concomitant influx of polymorphonuclear leukocytes in the lung. These observations raise the possibility that the inflammatory cells play a role in the cellular injury and increased airway permeability after O3 exposure. This study was the... | 0 |

SO2, HNO3. HONO and O3 in the gas phase and sulphate, nitrate and ammonium in particulate matter were measured. Indoor and outdoor values were similar.

42,253 | Respiratory and cardiovascular changes associated with toxic doses of a peptide antagonist of vasopressin in the rat | Murphy, DJ; Joran, ME | 1,992 | SK&F 101926 is a synthetic octapeptide which was designed to promote free water excretion by antagonizing the action of antidiuretic hormone. The clinical and pathologic changes in rats resulting from lethal doses of SK&F 101926 have suggested that death is associated with respiratory failure and/or cardiovascular coll... | 0 |
