The effect of air pollutants on lung surfactant surface tension

· J. Environ. Sci. Health, Part A; (United States)
This study is concerned with the effects of certain pollutants on the surface tension of pulmonary surfactant (..gamma..). Surface tension of the aqueous phase of a canine lung homogenate was measured by a ring tensiometer. Environmental pollutants (Cl/sub 2/, H/sub 2/O/sub 2/, HCl, H/sub 2/SO/sub 4/, NH/sub 3/ and SO/sub 2/) were added to the lung extract in liquid form. Variations of ..gamma.. with time, temperature and pollutant concentration were observed. Effects were observed with Cl/sub 2/, SO/sub 2/, H/sub 2/O/sub 2/ but not with NH/sub 3/, H/sub 2/SO/sub 4/ or HCl. No clear distinction was observed between oxidants and reductants, but some intriguing time variations were observed.
