The impairment of lung function caused by environmental exposure to pollutants and toxicants is a rising health problem, particularly in highly industrialized parts of the world. The problem is urgently calling for the development of new methodologies to assess both the level of elemental exposure and the effects for quality of health and longevity. This volume provides state-of-the-art information about the recent advances in occupational and non-occupational pollutant-related disorders of the respiratory tract, and the assessment of a threat they pose for the health-span. Heavy traffic-related air pollution, unnoticeable but salient health detriment, is dealt with at length.
