[Effect of increased ammonia concentrations in the atmosphere of closed chambers on various indicators of nitrogen and carbohydrate metabolism in men on controlled diets].

This paper presents data on nitrogen and carbohydrate metabolism in men kept in an enclosed environment with a high ammonium content (2 and 5 mg/m3) combined with a high temperature and humidity. The toxic environmental effect manifests itself when the ammonium concentration increases up to 5 mg/m3 in combination with a high temperature and humidity level. During this period protein catabolism and negative nitrogen balance enhance. It is recommended that vitamins should be added to the diet used under the above conditions.
