IDENTIFICATION AND USE: ABS resin is a plastic material made from acrylonitrile, butadiene and styrene. It is used in piping, automotive components, appliance components, components of business machines, telephones and electrical and electronic equipment, pipe fittings, recreational vehicle components. Other uses of acrylonitrile-butadiene-styrene copolymers include packaging; luggage and cases; toys and sporting goods; and furniture. Since September 1977, acrylonitrile-butadiene-styrene copolymers are no longer permitted in the fabrication of beverage containers. HUMAN EXPOSURE AND TOXICITY: The findings of epidemiology study conducted in Taiwan implied the ABS plastic injection-moulding process may worsen olfactory function among workers. Notably, this effect decreased olfactory threshold scores, not odor identification scores. ANIMAL STUDIES: The acute toxicity of ABS degradation products was found to be comparable with the toxicity of the thermal decomposition products of other common polymeric materials. Rats exposure to thermo-oxidation degradation products produced a decrease in tissue reduced glutathione concentration in liver and kidney but not in lung. Superoxide dismutase activity increased in liver and brain during the three-day exposure. In liver the activity reached the control value after the two-week exposure but the cerebral activity was significantly lower than in controls. In guinea pigs repeated exposure resulted in sensory irritation, coughing, and airways constriction and deaths, and there was evidence of cumulative respiratory effects, and slower recoveries among survivors. In mice recovery from the effects of exposure to ABS resin smoke was slower than recovery from exposure to smoke from Douglas fir chips, which was used as a comparison.

The Occupational Health Branch of the Ontario Ministry of Labour began a study in 1978 for the evaluation of health risks associated with acrylonitrile (AN) exposure. Detailed hygiene and medical investigations were conducted in fourteen plants for evaluating AN exposure in various industrial processes. Four companies were also studied in relation to mixed chemical exposure representing acrylic fibres, nitrile rubber, ABS-resin, and acrylic emulsions production. The possible interaction between AN and other coexisting chemical exposures was reviewed since dimethyl formamide, styrene, and butadiene have similar pharmacokinetics and possible synergistic effects. Exposure in acrylic fibre production may be synergistic and carcinogenic. Results of air monitoring indicated exposure levels to AN below 2 ppm (TWA) in most cases. Exposure to other co-existing chemicals was evaluated. Results of medical tests indicated no significant abnormalities in chest x-rays or liver function tests in currently exposed workers.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 119,649 workers (42,653 of these were female) were potentially exposed to ABS Resin in the US(1).

Two USA commercial copolymer samples examined were found to contain 30 and 50 mg/kg (ppm) residual, unreacted acrylonitrile monomer.

/EPIDEMIOLOGY STUDIES/ Plastics manufacturing factories are the fifth largest category of factories in industrial estates in Taiwan. It is known that complex airborne compounds and pungent odors are emitted during plastic injection-moulding processes. Workers exposed to acrylonitrile-butadiene-styrene (ABS) thermal decomposition products (TDP) may have olfactory loss. This study examined olfactory loss in injection-moulding workers exposed to ABS TDP. The method recommended by the Connecticut Chemosensory Clinical Research Center (CCCRC) was used to test the olfactory function of subjects, including 1-butanol threshold and odor identification, both pre- and post-work. The study sample included 52 ABS plastic injection-moulding workers (exposed group), as well as 72 workers from other departments (reference group). The results revealed that the exposed group had lower olfactory function after work than the reference group. The decrease in olfactory function after 1 workday was statistically significant. The prevalence of abnormal olfactory function post-work in the exposed group was higher than in the reference group. The findings of this study implied the ABS plastic injection-moulding process may worsen olfactory function among workers. Notably, this effect decreased olfactory threshold scores, not odor identification scores.

The polymer was a physical blend of a butadiene-acrylonitrile rubbery copolymer and a styrene-acrylonitrile copolymer. In the 1950' s, the technique of grafting styrene and acrylonitrile onto polybutadiene rubber was perfected, thus introducing the acrylonitrile-butadiene-styrene copolymers in use today. These copolymers were first produced commercially in Japan in 1964.|ABS contains over 50% styrene and varying amounts of butadiene and acrylonitrile. Some production is from swing capacity. ABS is the largest volume engineering thermoplastic. High impact polystyrene has become almost as expensive as ABS so some manufacturers have changed back to ABS resins

Fourier transform infrared (ftir) spectroscopy is the method of choice to identify the presence of an ABS polymer and determine the acrylonitrile-butadiene-styrene ratio of the composite polymer. Confirmation of the presence of rubber domains is achieved by electron microscopy. Comparison with available physical property data serves to increase confidence in the identification or indicate the presence of unexpected structural features. Identification of ABS via pyrolysis gas chromatography and dsc /Differential Scanning Calorimetry/ has also been reported.|Acrylonitrile-butadiene-styrene (ABS) resin manufacturing wastewater is a complicated, toxic and refractory industrial wastewater. Comprehensive and accurate analysis of the typical pollutants in ABS resin manufacturing wastewater is critical to develop cost-effective wastewater treatment technologies. In this paper, a comprehensively qualitative analysis combined with three complementary methods has been developed for the detection of typical pollutants in ABS resin manufacturing wastewater from three production sections, and thirty-seven compounds had been detected and further confirmed by this analysis method with standards. Simultaneous chromatographic separation and quantification of seven representative pollutants, including three mononuclear aromatics, three acrylonitrile dimers and one acrylonitrile derivative, were achieved by GC-FID system. The detection limits of this method for seven representative pollutants were in the range of 0.007-0.89 mg/L. The within-day and between-day precisions of this method were less than 6.5% (RSD, n=6). The recoveries of the representative pollutants reached 90-120%. The ABS resin manufacturing wastewater from E zone was successfully determined by this method, with two mononuclear aromatics and three acrylonitrile dimers accounting for 57.73% and 40.63% of the selected seven compounds, respectively. These results reveal that the removal of mononuclear aromatics and acrylonitrile dimers is a key to treat this wastewater.
