| Abstract |
Two large cutting fluid systems in an engineering industry were analyzed in order to study the formation of acetic aldehyde and formaldehyde in cutting fluids and its relation to irritation of mucous membranes and the skin. About 50 persons were exposed to each of the cutting fluids. The concentration of the aldehydes varied with time and between the cutting fluids. None of the analyzed parameters could explain the variable concentration of aldehydes. Mucous membrane irritation was much more common in one of the systems. The occurrence of symptoms was slightly associated with the concentration of aldehydes and pH of the fluid varied more in the fluid that caused most symptoms. A few measurements of ammonia indicated a higher concentration of ammonia in the fluid that caused most symptoms. It is concluded that irritation of mucous membranes and the skin may vary considerably between different cutting fluids of similar composition and use but the causal factor could not be determined in this study, however, a variable pH and an increased concentration of ammonia may be indicators in this context. Better markers for the surveillance of cutting fluids need to be developed. |
