L'analyse de quelques parametres biologiques chez les ouvriers de l'usine d'engrais chimiques ASMIDAL (Algerie), ainsi que chez les habitants d'une cite avoisinante (El Bouni) exposes aux emanations de cette usine, a montre des modifications de ces parametres en signe de contamination par des derives azotes. L'exposition experimentale par ingestion a une dose infraletale de nitrate d'ammonium, derive fabrique par ASMIDAL, a provoque, chez le rat, des modifications similaires a celles trouvees chez les personnes etudiees. Les variations ont concerne les taux d'hemoglobine, de methemoglobine, les globules rouges, les nitrates seriques et urinaires. En outre, on a constate chez le rat des modifications de l'activite de la rate et du foie
