Particulate Air Pollutants and Respiratory Diseases

Air pollution is composed of a mixture of toxins, consisting of particles and gases emitted in large quantities from many different combustion sources, including cars and industries. A variety of anthropogenic and natural particle sources are present in ambient air. Throughout the past decade, the composition of air pollution has changed in developed countries from classical type 1 pollution, c...

Respiratory effects of air pollutants: experimental studies in humans.

Epidemiological and environmental chamber studies in man, and toxicological studies in animals, have provided valuable insights into the biological effects, the mechanisms of action, and the dose-response characteristics of some major air pollutants. This review describes the information currently available on air pollutant effects in man, as the result of experimental studies. There are certai...

Genetic effects of air pollutants: insights from human biomonitoring studies.

In this issue Sree Devi and coworkers1 report the results of a cytogenetic investigation on traffic policemen from an Indian metropolitan area. The study shows a distinct excess of cytogenetic damage in peripheral blood lymphocytes of policemen compared to indoor workers, highlighting the genotoxic consequences of the exposure to urban air pollutants. Genetic damage, for the severity and irreve...

Long-term canine exposure studies with ambient air pollutants.

Dogs are often the species of choice as an experimental model for the study of pulmonary responses to long-term exposure to air pollutants in chambers simulating environmental or occupational exposure in man. Their lungs bear a reasonable resemblance to human lungs, they are large enough to allow serial measurements of pulmonary responses, and they live long enough to ensure that findings are n...
