40,386 | Induction of sister-chromatid exchanges in Chinese hamster V79 cells by exposure to the photochemical reaction products of toluene plus NO2 in the gas phase | Shiraishi, F; Hashimoto, S; Bandow, H | 1,986 | A study was made on the induction of sister-chromatid exchanges (SCE) in cultured Chinese hamster V79 cells exposed to the photochemical reaction products of toluene plus NO2 in the gas phase. The photochemical reaction products of toluene plus NO2 were obtained by photochemical reaction of a toluene--NO2/dry air syste... | 0 |

40,400 | Overview of the risk of respiratory cancer from airborne contaminants | Speizer, FE | 1,986 | This overview on defining risk of respiratory cancer from airborne pollutants summarizes broad issues related to a number of the environmental agents that are discussed in the articles that follow. Lung cancer kills more than 100,000 people annually and is the major form of cancer in both sexes in middle age. Cigarette... | 0 |

40,401 | Impairment of tracheal mucociliary clearance but not ciliary beat frequency by a combination of low level ozone and sulfur dioxide in sheep | Abraham, WM; Sielczak, MW; Delehunt, JC; Marchette, B; Wanner, A | 1,986 | We used conscious sheep to determine the effect of a combined exposure to ozone (O3) and sulfur dioxide (SO2) on tracheal mucus velocity (TMV) and ciliary beat frequency (CBF). TMV was measured in vivo by tracking the movement of radiopaque particles which had been deposited on the tracheal mucosa. CBF of tracheal epit... | 0 |
19,277 | The characterization of ozone, sulfur dioxide, and nitrogen dioxide for selected monitoring sites in the Federal Republic of Germany | Lefohn, AS; Mohnen, VA | 1,986 | Ambient ozone, sulfur dioxide, and nitrogen dioxide data collected at 11 rural gaseous air pollution monitoring stations located throughout the Federal Republic of Germany (FRG) were characterized to provide a basis for investigating the effect these air pollutants may have on forest decline. For any given year, with t... | 0 |
40,433 | Effect of ozone and histamine on airway permeability to horseradish peroxidase in guinea pigs | Miller, PD; Gordon, T; Warnick, M; Amdur, MO | 1,986 | Airway permeability was studied in groups of male guinea pigs at 2, 8, and 24 h after a 1-h exposure to 1 ppm ozone or at 2 h after a 1-h exposure to filtered air (control). Intratracheal administration of 2 mg horseradish peroxidase (HRP) was followed by blood sampling at 5-min intervals up to 30 min. The rate of appe... | 0 |
39,760 | Persistence of the acute effects of ozone exposure | Folinsbee, LJ; Horvath, SM | 1,986 | Reexposure to ozone 24 h after an initial exposure results in greater decreases in forced expiratory tests of lung function following the second exposure. The purpose of this study was to determine whether this hyperresponsiveness was present earlier than 24 h or persisted beyond 24 h. Four groups of subjects (n = 6,6,... | 0 |

After 7 days of exposure to 0.64 ppm of O3, lung coll... | 0 |
