1,3-Butadiene in air: Laboratory method using molecular sieve diffusion samplers, thermal desorption and gas chromatography
Contents of this guidance note: properties, uses, toxicity and first aid following massive exposure to 1,3-butadiene; determination method (butadiene gas migrates down the tube of a diffusive sampler and is adsorbed on the Molecular Sieve; collected gas is desorbed by heat and transferred to a gas chromatograph equipped with a flame ionisation detector). Scope: suitable for sampling over periods in the range 30min to 8h for personal or fixed location monitoring; analytical range: 2-100mg/m3. Changing the polarity of the column stationary phase may remove interference due to the presence of compounds coeluting with the butadiene.

Mortality among workers at a butadiene facility
Several studies of styrene-butadiene rubber (SBR) workers have reported excess cancers at various sites. The current study examined cause-specific mortality in a cohort of 2,586 male workers employed for at least 6 months between 1943-1979 in a butadiene manufacturing plant. Standardised mortality ratios were calculated using national (NSMR) and local (LSMR) comparison populations. The all-cause NSMR was 80 (p<0.05) and the all-cancer NSMR was 84; the corresponding LSMRs were 96 and 76 (p<0.05). No significant excesses were observed for any cause of death except lymphosarcoma and reticulum cell sarcoma (NSMR=235). When the cohort was subdivided into routine, non-routine, and low-exposure groups, the SMRs were consistently elevated for this cause of death in all 3 groups. This suggests that butadiene may not be responsible for the excess, but the association deserves close attention in future studies.

Chemical cartridge respirator performance: 1,3-butadiene
1,3-Butadiene recently has been classified as a potential occupational carcinogen. The performance of Scott organic vapour (642-OV), organic vapour/acid gas (642-OA) and acid gas (642-AG) twin cartridges was determined for 1,3 butadiene. A cartridge test system was developed to generate challenge concentrations of 100ppm and 1000ppm; an infrared analyser was used to measure breakthrough at 10ppm. The twin cartridges tested demonstrated reasonable adsorption capacity for 1,3 butadiene. Cartridge service life was inversely proportional to airflow rate; it was reduced at elevated temperature and humidity conditions. Breakthrough times were approximately three times longer at 100ppm than at 1000ppm. When clean air was drawn through cartridges saturated with 1000ppm 1,3 butadiene, desorption occurred readily. The rate of desorption and the peak concentration were dependent upon the temperature, humidity and degree of saturation.

Inhalation exposure of rats and mice to 1,3-butadiene (BD) at 625-8000ppm induced a carcinogenic response at multiple sites. Offspring of pregnant rats exposed to BD at 8000ppm had major skeletal defects, and foetal toxicity was observed after exposure at 200-8000ppm. Workers employed in facilities producing styrene-butadiene rubber showed an increased, but not statistically significant, risk of mortality from neoplasms of the lymphatic and haematopoietic tissues and from leukaemia. BD should be regarded as a potential occupational carcinogen and teratogen and a possible reproductive hazard.

Determination of butadiene concentration in air by gas chromatography
Oznaczanie stężenia butadienu w powietrzu metodą chromatografii gazowej [in Polish]
Two methods of gas chromatographic analysis were developed to determine butadiene in air. The 1st involves the use of a 3m column of dimethylsulphonal on Chromosorb P and a thermoconductimetric detector, and the other, a 3m column of Reoplex 400 on alumina and a flame ionisation detector. Butadiene can be determined directly from the gas sample within 7h after sample collection, later on from a solvent-enriched sample. It was possible to determine butadiene at 0.3 times the TLV.

Environmental epidemiologic investigation of the styrene-butadiene rubber industry - Mortality patterns with discussion of the hematopoietic and lymphatic malignancies
After 2 men had died of leukaemia at 2 styrene-butadiene rubber production plants, their cases were studied by NIOSH on the basis of records from 1943 and 1950, respectively, until 1976. There was no statistically significant excess in total or cause-specific mortality in the overall worker population of either plant. One plant showed a non-significant excess of leukaemia and aleukaemia (standardised mortality ratio (SMR) 203). A subgroup of white males with at least 6 months' employment had an SMR of 278 for these categories, also not statistically significant. Production or manufacture of styrene-butadiene rubber may be associated with an excess of lymphatic and haematopoietic neoplasms.

A hematology survey of workers at a styrene-butadiene synthetic rubber manufacturing plant
Personal air samples and blood specimens were obtained from 157 production workers in order to determine exposure levels for styrene, butadiene, benzene and toluene and any haematologic variations, in a population at a facility in which a previous excess of leukemia and lymphoma mortality had been found. Exposure levels for all 4 chemicals were below recommended standards. The highest mean styrene and butadiene concentrations, 13.67 and 20.03ppm respectively, were found in the tank farmer area. In all other departments the mean levels for the 4 chemicals were < 2ppm. The tank farm workers had slightly lower levels of circulating erythrocytes, haemoglobin, platelets and neutrophils, and slightly higher mean corpuscular red cell volumes and neutrophil band counts than the other workers. No pronounced evidence of haematologic abnormality was found in this group.

Parameters of the kallikrein-kinin system in synthetic rubber workers suffering from neurocirculatory dystonia
Pokazateli kallikrein-kininovoj sistemy u bol'nyh nejrocirkuljatornoj distoniej, rabotajuščih na proizvodstve sintetičeskogo kaučuka [in Russian]
Blood levels of kallikrein were elevated and levels of kallikreinogen, kininogen and kininase were reduced (in comparison with control levels) in synthetic rubber workers who suffered from neurocirculatory dystonia as a result of exposure to alpha-methylstyrene and divinyl (butadiene); patients with neurocirculatory dystonia of psychogenic origin showed only an elevation in kallikrein and depression in kininogen. The alterations in enzyme and zymogen levels seen in the rubber workers indicate a disturbance in their liver function. A programme of therapy for these patients should include treatment with inhibitors of the kallikrein-kinin system.

Proceedings of NIOSH styrene-butadiene briefing.
The National Institute for Occupational Safety and Health held a briefing (Covington, Kentucky, 30 Apr. 1976) to explore with concerned persons from government, labour, management, and academic areas the implications of data on the possible linkage between exposure to styrene-butadiene and leukaemia deaths, the potential problems to be anticipated, and alternatives for action. Chemicals and working conditions in 2 Port Neches, Texas, styrene-butadiene plants were described. Reports of disease among workers included 8 leukaemia deaths in these 2 plants; a 6-fold excess of leukaemia and lymphoma deaths in an Akron, Ohio, plant; 1 death from leukaemia and 2 from Hodgkin's disease in a Louisville, Kentucky, plant; and 2 leukaemia deaths and 1 lymphoma death among 563 styrene workers in a plant in Pennsylvania. Speakers presented suggestions for epidemiologic studies, both industry-wide and in specific plants, and discussed sampling and analytical methods, engineering controls, work practices, and standards development as they relate to controlling exposures in styrene-butadiene plants.

Study of the composition of volatile products given off during moulding of polymers and copolymers of styrene
Badanie składu produktów lotnych emitowanych przy przetwórstwie polimerów i kopolimerów styrenu [in Polish]
Description of a technique for identification and determination of the products given off during injection or extrusion moulding of plastics. Based on gas chromatography, it requires a pyrolysis cell of special design. Substances identified and determined in laboratory experiments with the commonest styrene polymers and copolymers (200-300°C; heating time 0.5-5min.): styrene, ethylbenzene, benzene and toluene, acrylonitrile and hydrogen cyanide. Analysis of factory samples confirmed the emission of the substances detected by the laboratory technique, which can also be easily modified for other groups of plastics. Graphs and tables complete the description and interpretation of results.

Use of anaphase studies for estimating bone-marrow chromosome aberrations in the hygienic assessment of the mutagenic effect of polymer building materials
Ispol'zovanie anafaznogo metoda učeta hromosomnyh perestroek v kostnom mozge pri gigieničeskoj ocenke mutagennogo ėffekta polimernyh stroitel'nyh materialov [in Russian]
Literature review and results of animal experiments concerning the chromosome aberrations induced by exposure to polymer-containing concretes and putties. It was found that polymer concretes which produced no chronic toxic action in animals had no cytogenic effect. Polymer putties containing unsaturated hydrocarbons, petrol, divinyl and xylene caused changes characteristic of certain toxic effects and an increase (by a factor of almost 2) in the number of chromosome aberrations as compared with a control group.

Working conditions and health status of automobile tyre vulcanizers
K harakteristike uslovij truda i sostojanija zdorov'ja vulkanizatorščikov avtopokryšek [in Russian]
Industrial hygiene surveys in tyre-vulcanisation plants revealed, in particular, the following hazards: arduous physical work, hot micro-climate; noise; atmospheric pollution with styrene, butadiene, carbon monoxide, nitrogen oxides, etc. (a total of 50 organic compounds). Medical examination of 180 exposed workers revealed muscle, bone and joint lesions of the upper extremities (including the scapulohumeral joint), relatively frequent nervous system functional disorders, smell and balance disorders, and dystrophic disorders of the respiratory tract mucosae. The authors recommend complete mechanisation of mould insertion and extraction procedures and effective thermal insulation of vulcanisation vessels.
