Pure acetylene is relatively nontoxic to man. It acts as a simple asphyxiant and produces ill effects only by reducing available oxygen. Emissions of acetylene are estimated to have been 9 million pounds in 1974. These occur only from manufacturing and end use. Although there are no specific processes mentioned in the literature for the control of acetylene emissions, absorber/scrubber systems are used in manufacturing operations for product purification. Simple diffusion model calculations place maximum expected 1-hour average ambient concentrations at about 5.5 ppm, and at about 3 ppm for 24-hour values near a plant boundary. Urban concentrations of about 80 ppb and rural values of 1 ppb have been measured. Based on the low toxicity and expected low ambient concentrations, it appears that acetylene does not pose a health or environmental hazard as an air pollutant.
