Abstract: The integral toxicity of solutions of a number of carboxylic acids was estimated by measuring their chemical oxygen consumption (COC) and the biochemical oxygen demand for the biodegradation of substances due to microorganisms (BOD5). The analytical dependences of COC and BOD5 as well as of their ratio for these compounds on concentration were determined. The values of COC and BOD5 for a number of acid solution mixtures were measured. The coefficient that indicates biodegradability of substances has been calculated. The chemical consumption of oxygen by solutions of organic acids is shown to increase with the transition from lower to higher homologues and with increase in the concentration of the solution.
