Alcohol and yeast production is the most important part of the biotechnological production in Yugoslavia, with annual production of 13 667 867 liters of absolute alcohol and of 20 947 490 kg of yeast in the year 1998. Large environmental load is produced by wastewaters from alcohol and yeast factories (512 000 P.E.), especially by alcohol stillage (BOD 40 000 - 50 000 mg/L). Anaerobic treatment is suitable process for treatment of alcohol stillage, and of yeast factory wastewater. In this paper, effects of treatment process (organic load reduction, energy of produced biogas) are discussed; and potential of anaerobic treatment os wastewaters from Yugoslavia's alcohol and yeast factories is reviewed.

International audience | Hospital wastewater (HWW) receives increasing attention because of its specific composition and higher concentrations of some micropollutants. Better knowledge of HWW is needed in order to improve management strategies and to ensure the preservation of wastewater treatment efficiency and freshwater ecosystems. This context pushed forward the development of a pilot study site named Site Pilote de Bellecombe (SIPIBEL), which collects and treats HWW separately from urban wastewater, applying the same conventional treatment process. This particular configuration offers the opportunity for various scientific investigations. It enables to compare hospital and urban wastewater, the efficiency of the two parallel treatment lines, and the composition of the resulting hospital and urban treated effluents, as well as the evaluation of their effects on the environment. The study site takes into account environmental, economic, and social issues and promotes scientific and technical multidisciplinary actions. ᅟ.

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
