Mortality among workers in a shoe manufacturing company
A case-control analysis of patient files at a large cancer treatment facility indicated that several bladder cancer patients had worked at a large shoe manufacturing company in the state of New York, USA. A mortality study was initiated to determine whether there was an unusual cancer risk associated with employment in this facility. Because company records were not available, local newspaper obituaries were used to identify former company employees who died between 1960 and 1979. Proportionate mortality analyses were conducted by using 4,734 death certificates and the general U.S. population for comparison. There were no excess deaths from nasal cancer or bladder cancer, and mortality from leukaemia was slightly lower than expected. Increased relative frequencies of digestive cancers were seen among men and women. There were significant excesses of deaths from multiple myeloma among both men and women.

Nasal cancer in the U.S. shoe industry: Does it exist?
Three recent, large-scale mortality studies in the USA do not show any deaths from nasal cancer as shown in other countries. The methodology of these studies is reviewed. Epidemiological and other considerations important in the assessment and interpretation of the absence of the risk are discussed.

Occupational exposure to benzene in the shoe industry
Phenol in urine and benzene and toluene in blood were determined (33 workers) as indexes of benzene exposure where the benzene may be an undeclared constituent of solvents. Benzene and toluene were found in all samples; the amount of toluene was 4 times that of benzene. An increase in urinary phenol concentration might be a sufficiently sensitive parameter to assess benzene exposure when other data concerning the presence of benzene are not available.

Historic cohort study in Montreal's fur industry
A historic cohort mortality study was carried out among 2 groups of male workers (mean age: 43.2 years; mean number of years since first employment: 14.1 years; follow-up after cohorts were established: 15 years) in the Montreal fur industry: 263 dressers and dyers and 599 fur garment workers. One group was exposed to a large variety of chemicals (including carcinogens and mutagens) used in tanning, cleaning, and dyeing fur, and the other to residue from the dressing and dyeing stage and to respirable fur dust. Observed deaths were compared with those expected based on mortality rates of the population of metropolitan Montreal. Standardised mortality ratios (SMRs) for the garment workers significantly low, probably because of the ethnic composition of the cohort and a healthy worker effect. SMRs for the dressers and dyers were also low, but not as low as for the garment workers. For French Canadians in the cohort, the observed deaths were close to the expected; there was a noteworthy excess of colorectal cancer (4 observed, 0.8 expected) for dressers and dyers. Apart from this weak suggestive evidence, results did not indicate any excess mortality risks in the fur industry. However, because of the relatively small number of expected and observed deaths in the cohort and especially among the heavily exposed dressers and dyers, confidence intervals around SMR estimates were wide and excess risks cannot be ruled out.

Urinary excretion of 2,5-hexanedione and peripheral polyneuropathies in workers exposed to hexane
40 shoe factory workers who were exposed to hexane were investigated to see if there was a correlation between electroneuromyographic changes indicative of neuropathy and urinary excretion of the metabolic products of n-hexane and its isomers. 2,5-Hexanedione and γ-valerolactone were discovered in all cases, while 2-hexanol was found in 11 cases. 2,5-Hexanedione was the main metabolite in 39 cases. Metabolic products of cyclohexane were present in about one-fifth of the cases, while trichloroethanol, a metabolic product of trichloroethylene, was nearly always present, all at very low concentrations. Electromyographic abnormalities significant for early detection of toxic polyneuropathy were found in 14 cases. A statistically significant correlation of the electroneuromyographic scoring with the urinary metabolites was observed only for 2,5-hexanedione and γ-valerolactone. Since γ-valerolactone is probably not a true metabolite of n-hexane, the results support the hypothesis that polyneuropathies in shomakers are due to 2,5-hexanedione. For practical purposes the urinary concentration of 2,5-hexanedione can serve as a predictive measurement for early detection of neurotoxic lesions at preclinical stages.

Neurophysiological study of a group of workers exposed to technical heptane in a rubber shoe factory
Indagine neurofisiologica su un gruppo di lavoratori esposti ad eptano tecnico in una fabbrica di calzature in gomma [en italiano]
This study involved 50 workers exposed to technical heptane and 2 groups of controls of roughly equal size. The technical heptane had the following composition: 38-40% n-heptane, 8-10% 3-methylhexane, 27-30% 2-methylhexane, 17-21% methylcyclohexane, <0.2% n-hexane and <3% other solvents (toluene, etc.). Exposure levels at work stations did not exceed TLV-TWA levels set by ACGIH for n-heptane. Nevertheless, in the exposed workers there was a significantly raised level of subclinical neuropathy involving the most distal sensitive tracts of the median nerve. Dysaesthesia and asthenia of the limbs were the most frequently noted subjective neurological symptoms among the exposed workers. No correlations were found between duration and extent of exposure to n-heptane and total technical heptane on one hand, and measured neurological functions on the other. It is recommended that TLVs be set for the components of technical heptane.

Working conditions in the shoe industry. Study in 4 factories
Conditions de travail dans l'industrie de la chaussure - Etude dans quatre entreprises [en francés]
In order to improve working conditions in a particular sector, a sound knowledge of the hazards and stresses which characterise that sector is required. Therefore, several research teams carried out a survey of working conditions in 4 shoe factories. The survey comprised observation, workplace environment measurements and questionnaires, concentrating mainly on solvent exposure and ventilation, physical environmental stressors (noise and heat), stresses related to time and work organisation and workplace layout.

Cabinas de dar cola: Sistemas de ventilación localizadas para el control del riesgo higiénico en los puestos de dar cola en la industria del calzado/Cabinas de dar cola: Sistemas de ventilación localizadas para el control del riesgo higiénico en los puestos de dar cola en la industria del calzado
Vapours of organic solvents from the glues used in the manufacture of shoes constitute an important health hazard. This article describes a study of the hygienic conditions in 318 gluing workplaces belonging to 166 companies in the province of Alicante, Spain. A large number of workers were exposed to high concentrations of, in particular, n-hexane, hexane and toluene. In many cases the concentrations exceeded the exposure limits. The gluing desks provided with a hood and an exhaust device showed to be very effective in reducing exposure when used properly, while desks without hoods and with the exhaust tube placed underneath were not acceptable. Recommendations for safe working conditions are included in the article as well as brief chemical safety data sheets on n-hexane, toluene, benzene, butanone, ethyl acetate and acetone.

Monitoring of carcinogenic risks in tannery workers by means of desquamative lung and bladder cytology and urinary mutagenicity
Proportional mortality data on a cohort of tannery workers showed an increased risk of lung cancer, oesophageal cancer, sarcomas and leukaemias. From a cohort of workers and controls in the same area, data were obtained on urinary mutagenic activity using Salmonella typhimurium TA1538 and TA100 as tester strains, with and without metabolic activation. The mutagenic activity of the urine of tanning workers did not differ from that of clerical workers. Bladder desquamative cytology did not show any difference between clerical controls and workers. Pulmonary cytology specimens were normal or showed cellular atypical metaplasia. No cases with atypical cells or obvious neoplastic changes were found. The relative risk of pathological lung cytology was higher in chemical refining than in mechanical refining and tanning.

Bladder cancer and occupational exposure to leather
A case-control study of 2982 cases of bladder cancer and 5782 controls in the USA showed an odds ratio of 1.4 (95% confidence limits: 1.0, 1.9) after adjustment for sex, age and cigarette smoking. The risk was highest among those first employed in a job involving exposure to leather before 1945. No dose-response relationship was found. Those employed in "dusty" leather jobs had a slightly higher risk of bladder cancer than those with other types of exposure to leather.

Occupation and cancer in London: an investigation into nasal and bladder cancer using the Cancer Atlas
This case-referent study of male deaths in certain boroughs of London (United Kingdom) found a significant relationship between nasal cancer and occupations involving heavy exposure to wood dust on one hand, and between bladder cancer and road transport driving and the handling of leather on the other. Consistently raised relative risk ratios for bladder cancer were also found for some other occupations (woodworking, fitting, printing, machining, plumbing and automobile repair).

Investigation of the vibration of punch presses in the shoe industry and of ways to reduce it
Issledovanie vibroaktivnosti vyrubočnyh pressov obuvnoj promyšlennosti i puti ee sniženija [en ruso]
The noise and vibration emitted by two typical presses for punching out shoe soles were measured and the vibroacoustic fields on and around the machines were mapped. Noise and vibration levels were positively correlated. Maximum noise and vibration in the operating cycle occurred at the point where the sole material had just been punched through. It is proposed that hard rubber or plastic be used to shroud the presses, that they be coated with mastic having a modulus of elasticity of 109N/m2, and that areas of high-frequency vibration be damped with softer coatings (modulus of elasticity 107N/m2).

Neurologic findings in persons exposed to toluene for long periods
Neurologické nálezy u osob dlouhodobě exponovaných toluenu [en checo]
The health status of 25 shoe factory workers exposed to adhesives containing toluene was examined. The MAC for toluene in workplace air was exceeded, and the urine of the exposed persons had elevated levels of hippuric acid. Subjective neurovegetative complaints were recorded in 85% and objective neurotic symptoms in 60% of the workers. EEG recordings differed from those seen in healthy members of the general population.

Epidemiological investigations into the haematotoxic and hepatotoxic effects of benzene and benzene-containing mixed solvents
Epidemiologische Untersuchungen zur hämatotoxischen und hepatotoxischen Wirkung von Benzen und benzenhaltigen Lösungsmittelgemischen [en alemán]
An assessment of the data on 85 persons newly registered between 1973 and 1982 as suffering from occupational disease due to exposure to benzene has shown that this intoxication occurs primarily in the chemical and shoemaking industries. The disease has to be considered severe, because >20% of the affected persons have a disability of > 50% and/or die of the consequences of the intoxication. The mean exposure time was 15.2 (2-38) years. Only 16% of the persons newly registered as suffering from this occupational disease had been exposed to benzene alone. All the other persons were exposed to mixed solvents. After elimination of the persons who were abusing alcohol and those suffering from previous non-occupational lesions, the assessment reaffirms the haematotoxic effect of benzene; liver lesions are the result of the simultaneous effect of other solvents, especially alcohols. No hepatotoxic effect can be attributed to benzene.

Mortality of tanners
A follow-up mortality study of 833 men known to be working in the tanning industry in 1939 in the United Kingdom (573 worked in making leather tanned by vegetable extracts for soles and heels, 260 in making leather tanned by chrome, for the upper parts of shoes). There were no significant excesses of deaths due to any commonly occurring cancer. In fact, among workers in the first group, deaths from all causes and deaths from causes other than malignant neoplasms were significantly lower than expected. There was 1 death due to nasal cancer and 1 death due to soft tissue tumour.

Contact dermatitis in workers processing polyvinyl chloride plastics
Results of patch tests of 2 groups (30 with and 30 without skin lesions) chosen from 400 workers in a plastic shoe factory. The tests included a standard battery of substances plus 4 phthalates widely used as plasticisers. Of the 11 workers with contact dermatitis, 6 were sensitive to phthalates and 5 to coal tar (also present in the granulated vinyl raw material). Reactions to dioctyl phthalate were even more numerous among the asymptomatic subjects than among the others, which shows the high sensitising potential of phthalates.

Methyl ethyl ketone exposure in industrial workers - Uptake and kinetics
Very little data being available on the uptake, distribution, biotransformation and elimination of methyl ethyl ketone (MEK), the present study compares alveolar concentrations of MEK with exposure and with blood MEK concentrations. Urinary excretion of MEK and its metabolite, acetylmethylcarbinol, was also compared with exposure. The solubility of MEK in body tissues and a multicompartmental model allowed the estimation of the distribution and kinetics of MEK.

Mortality study of workers in a tanning mill
Studio di mortalità fra i lavoratori di una conceria [en italiano]
A mortality study of 722 men and 320 women with at least 6 months work experience in a tannery. When compared with the overall mortality rate of their city of residence (Genoa, Italy), adjusted for sex and age, the only significantly raised cause of death was intestinal cancer (8 observed versus 4.3 expected). Overall mortality rate among the workers was actually lower than expected, probably because of the healthy worker effect.

Ergonomic intervention in the workplace in a plant manufacturing rubber-soled shoes
L'intervento ergonomico su di un posto di lavoro nell'industria delle calzature con suola in gomma [en italiano]
An ergonomic methodology and its practical application in a shoe factory are described. 3 types of curing presses were considered: manual, semi-automatic and automatic. Tasks were analysed at each press type according to their environmental hygiene aspects (microclimate, noise, dust and vulcanisation fumes, lighting), according to their ergonomics (cardiac effort, posture, psychological factors) and according to their safety. Most aspects of work improved with the use of automatic and semi-automatic presses, but dust and vulcanisation fumes increased, and so did the number of burns.

n-Hexane metabolism in occupationally exposed workers
This study was conducted on 10 workers in a shoe factory. The n-hexane concentrations in the workplace air ranged from 8-1143mg/m3 over 8h, with a median concentration of 243mg/m3. Alveolar retention of n-hexane was about 25%, corresponding to a lung uptake of 17%. Post-exposure alveolar excretion (monitored for 6h) was about 10% of the total uptake. The main metabolites of n-hexane were determined in urine samples collected before, at the end, and 15h after the work shift. Urinary concentrations were low, though related to original n-hexane concentrations in air. The best estimate of overall exposure was provided by end-of-shift concentrations of 2,5-hexanedione, 3mg/g creatinine of which would correspond to ab. 50ppm of n-hexane in air (mean daily exposure).

Pulmonary function and concentrations of alpha1-antitrypsin and immunoglobulin E in workers exposed to pancreatic enzymes
14 male workers exposed to pancreatic enzymes in a tannery, and a group of 14 non-exposed referents matched for age, sex, height and smoking habits, were studied by interview, spirometry and the single-breath nitrogen washout technique. Symptoms in the airways were reported by 7 of the subjects when weighing pancreatic enzymes. The exposed group did not show any deterioration in pulmonary volumes, forced expiratory flow, airway closure, or gas distribution when compared to the referents, and the serum levels of IgE did not differ between the groups. The exposed group had significantly higher plasma levels of α1-antitrypsin, possibly due to a compensatory response to increased levels of proteases within the lungs.

n-Hexane-induced polyneuropathy in the shoe and leather industries: modifications in its clinical features and epidemiology following partial measures of primary prevention
Polineuropatia da n-esano nell'industria calzaturiera e pelletiera: modificazioni del quadro clinico-epidemiologico a fronte di parziali misure di prevenzione primaria [en italiano]
A study of 15 cases of neuropathy in an Italian shoe and leather-goods factory, occurring in the period 1975-1980. Data were collected on symptoms, length of disease, factory output, concentration of various chemicals in the air of the factory (compared with their TLV's). Polyneuropathy, due to the presence of n-hexane in the air, disappeared once preventive measures eliminated its cause.

n-Hexane-induced changes in nerve conduction velocities and somatosensory evoked potentials
The cerebral evoked responses to 256 electrical stimulations of the median nerve were averaged in 15 women from a shoe factory and 15 controls. Maximal motor conduction velocity and distal sensory conduction velocities were significantly reduced in the exposed workers. Some components of the somatosensory evoked potentials (SEP) had an increased latency. Results were not completely consistent. SEP may give additional information on nervous function even in subjects with peripheral neuropathy. SEP results suggested some neurotoxic effects of n-hexane on the central nervous system too.

Chromium compounds: production and occupational exposure
Brief description of the production of chromium-containing chemicals and alloys, and literature survey of occupational exposure in the welding, chromate, chromium plating, ferrochromium, tanning and leather working and chromium pigment industries. For most occupations, exposure is to a mixture of Cr oxidation states and solubility fractions with a few notable exceptions: in the tanning industry, exposure is almost exclusively to soluble Cr(III), in the plating industry to soluble Cr(VI), and in the pigment industry, some wokers handling only lead chromate are exposed primarily to insoluble Cr(VI). Because of the wide variety of physical and chemical characteristics of the material of which airborne occupational exposures are composed, one can expect that the deposition, accumulation, clearance, bioavailability and pharmacokinetics of chromium differs widely from industry to industry, and great care must be taken in comparing exposures.
