Abstract
Za određivanje toksičnosti otpadnih voda u našem laboratoriju uveli smo Offhausovu metodu. Upotrebljavamo Warburgov aparat i manometrijsku tehniku rada, odnosno Sapromat i volumetrijsku tehniku rada. Obje su aparature jako skupe i nisu dostupne svim industrijskim vodnim laboratorijama. Zbog toga smo pokušavali uvesti metodu prema Borovičkovoj i Zahrádku koja se koristi jednostavnim aparatima. Rezultati uspoređivanja pokazuju da je metoda prema Borovičkovoj i Zahrádku za određivanje toksičnosti odnosno inhibicijskih efekata otpadnih voda nesigurna pa je zbog toga ne preporučujemo.The Offhaus method for the wastewater toxicity determination was introduced in our laboratory. The determination can be carried out by Warburg apparatus and manometric technique of work or Sapromat and volumetric technique of work. Both apparatuses are rather expensive and therefore not easily available to all the industrial water laboratories. On that account we tried to introduce the method of Borovickova and Zahrádka which requires a simple equipment. Unfortunately the comparative results show that the method of Borovickova and Zahrádka of the waste water toxicity determination is unreliable and therefore cannot be recommended
