Nephrotoxic effects of thermal decomposition mixtures of type C hydraulic fluids.
A survey was conducted to check the toxicological impact of ethylene glycol present in a thermal decomposition mixture of type C hydraulic fluid on laboratory animals submitted to an inhalation test. The target organs, i.e. kidneys, of exposed rats were evaluated histologically and oxalic acid--the ethylene glycol metabolite thought to cause renal failure--was quantified in urine samples. The results show that the low ethylene glycol concentrations present in the inhalation chamber produce only a temporarily increased oxalic acid excretion, at levels that are not significant. These findings are supported by the histological evaluation of the kidneys showing no calcium oxalate deposits or other abnormalities.
