Environmental causes of lung disease

SRI researchers conducted a series of studies that modeled the pathogenesis of human respiratory diseases such as emphysema and chronic obstructive lung disease. The studies proved that these diseases were caused in humans by common contaminants of air derived from industrial and automobile exhausts and tobacco smoke. The results were fundamental to national and international efforts in setting allowable limits of nitrogen oxide and ozone contents in industrial exhausts and indoor air-quality standards.
