Effect of sulphur dioxide inhalation on serum Na and K+ ion concentration in albino rat.

A study was carried out to assess the effect of 60 ppm and 120 ppm exposure of sulphur dioxide gas for one hour daily for 2 and 4 week on serum sodium(Na+) and potassium (K+) ion concentration in albino rat, Rattus norvegicus (Berkenhout). The present findings reveal that serum sodium (Na+) ion concentration increased significantly after 4 week exposure to 120 ppm of sulphur dioxide, while serum potassium ion (K+) concentration decreased significantly after 4 week exposure to 120 ppm of sulphur dioxide.
