||A review of exposure conditions and possible health effects associated with aerosol and vapour from low-aromatic oil-based drilling fluids
||Apr. 1990, Vol.34, No.2, p.149-157. 38 ref.
||This paper reviews investigations on possible health effects after inhalation of aerosols and vapours from the low-aromatic oil-based drilling fluids which have replaced diesel-based fluids. The main advantage of the low-aromatic base oils with respect to health hazards is their lower volatility. As a result of enclosure and local extract ventilation it has been possible to reduce time-weighted average concentrations of aerosols and vapours to below 100mg/m3. Effects on the central nervous system have only been observed at higher concentrations of these hydrocarbons, and male rat hydrocarbon neuropathy is not considered predictive of a normal human response. Insufficient information is available on possible long-term effects of exposure to the low-aromatic oil-based drilling fluids, especially regarding carcinogenicity and changes in the lungs.
