Three classes of construct were used which gave a range of elevated levels of glutathione reductaee (GR) activity in the cytosol (GR32), chloroplasts (GR36), or in both chloroplasts and mitochondria (GR46}. In some transgenic progeny (T z) from self-fertilized ... | 0 |
16,996 | Large-scale pollution of the atmosphere over the remote Atlantic Ocean: evidence from Bermuda | Dickerson, RR; Doddridge, BG; Kelley, P; Rhoads, KP | 1,995 | National Science Foundation. Ozone acts as a greenhouse gas and controls much of the oxidizing capacity of the atmosphere. Photochemical production of ozone in urban areas (smog) is a serious environmental problem, but how far this process extends on regional or global scales remains a major unanswered question in atmo... | 0 |

92,748 | Base cation depletion and potential long-term acidification of Norwegian catchments | Kirchner, JW; Lydersen, E | 1,995 | Long-term monitoring data from Norwegian catchments show that since the late 1970?s, sulfate deposition and runoff sulfate concentrations have declined significantly. However, water quality has not significantly improved, because reductions in runoff sulfate have been matched by equal declines in calcium and magnesium ... | 0 |
77,593 | Associations between criteria air pollutants and asthma | Koren, HS | 1,995 | The evidence that asthma is increasing in prevalence is becoming increasingly compelling. This trend has been demonstrated not only in the United States, but also in the United Kingdom, New Zealand, Australia, and several other Western countries. In the United States, the increase is largest in the group under 18 years... | 0 |

Ozone is a major constituent of air pollution in the summer. Epidemiological studies have demonstrated that there is an increase in hospital admissions for respiratory diseases 1 day after peak levels of ambient ozone. This may be due to an increase in the responsiveness of the airways to bronchoconstrictor stimuli.... | 1 |
