Possible toxic metal exposure of prehistoric bronze workers
An attempt was made to assess the possible occupational exposure to arsenic, lead, and mercury during the Bronze Age. Archaeological, metallurgical, and historical evidence is combined to form a picture of the potential toxic hazards. In the case of arsenic, a definite picture emerges of the effect of toxicity as a useful material is abandoned for health reasons on discovery of an acceptable alternative.

Some effects of cigarette smoking, arsenic, and SO2 on mortality among US copper smelter workers
This is a report on the 1949-1980 mortality experience of 6,078 white male workers who worked for at least 3yrs between 1 January 1946 and 31 December 1976 at 1 or more of 8 copper smelters. The completeness of the cohort was verified statistically, and worker exposures to arsenic, SO2, dust, nickel, cadmium, and lead were estimated from retrospective surveys. By using internal controls, a dose-response relationship for lung cancer was observed with exposure to arsenic and SO2. When cigarette smoking data were included with arsenic and SO2 exposure data in a nested case-control analysis, only smoking and arsenic were statistically significant factors. The arsenic-lung cancer relationship was confined to a single smelter where the raw materials had a high arsenic content. In the remaining smelters, mortality for all causes of death and for all cancer was not high based on comparisons with national, state, and local rates.

Neuropsychological impairment following inorganic arsenic exposure
A 50 year-old chemical engineer, routinely screened for occupational arsenic exposure, was admitted with a delirium for which no known aetiology was found. Elevated levels of arsenic were found in the urine and hair. The patient received chelation treatment with British anti-Lewisite; substantial amounts of arsenic were excreted and the toxic encephalopathy improved gradually over an 8-month follow-up period. The patient was tested at 6 weeks, 4 months, and 8 months postdelirium with a battery of neuropsychological tasks. The pattern of results showed verbal learning and memory to be severely impaired while tests of general intellectual abilities and language remained unaffected. Follow-up examinations with no subsequent re-exposure revealed improvements on specific cognitive tasks. It is unclear whether recovery of cortical functions occurred or if compensatory strategies were developed. It is proposed that a subacute exposure to arsenic may have contributed to the neuropsychological deficits.

Histological types of lung cancer among smelter workers exposed to arsenic
The histological distribution of lung cancer was investigated in 93 men who had worked at a Swedish smelter with high atmospheric levels of arsenic. A comparison was made with a group of 136 patients with lung cancer from the county where the smelter was located. No pronounced differences in the histological types of lung carcinomas between smelter workers and the reference group could be seen for smokers. Some analyses indicated an increased proportion of adenocarcinomas among the smelter workers, which confirmed earlier data, but these findings were difficult to interpret. Cases among smelter workers who had never smoked showed a histological distribution resembling that in smokers, indicating that the work environment at the smelter and smoking had a similar influence on the risk for different types of lung cancer.

Review of potentially harmful substances - Arsenic, mercury and selenium
Review of the human health aspects of marine pollution by arsenic, mercury and selenium. Inadequate data on the toxicology of the organic arsenic compounds found in seafood do not allow a reasonably accurate assessment of the possible health risks to man following long-term high intake. Seafood may occasionally contribute considerably to the daily intake of the more toxic inorganic arsenic. Seafood is the main source of methylmercury intake by man and groups with a high fish intake can easily exceed the WHO Provisional Tolerable Weekly Intake level. Marine food products contain substantial amounts of selenium, but even a high daily consumption is unlikely to cause undesirable exposure levels.

Past exposures to airborne fibers and other potential risk factors in the European man-made mineral fiber production industry
A historical environmental investigation was undertaken in European man-made mineral fibre factories (MMMF) to assess past exposures to MMMF and other environmental risk factors (asbestos, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, formaldehyde, and arsenic). A self-administered questionnaire completed by each plant management and an interview of the respondents were used. Addition of oil to the MMMF, change in the nominal fibre size of the bulk MMMF, and elimination of early discontinuous production techniques were identified as principal changes. The absence of oil, small nominal size, and labour-intensive production have been judged to be associated with higher airborne fibre levels.

Study of urinary arsenic: Method of determination without preliminary ashing for the monitoring of workers exposed to arsenic anhydride
Etude de l'arsenic urinaire: interêt d'une méthode de dosage de l'arsenic urinaire sans minéralisation préalable pour la surveillance des salariés exposés à l'anhydride arsenieux [in French]
This article describes a determination method, as tested on miners of mispickel (a mineral containing arsenic trioxide) and on workers who recuperate arsenic anhydride from the mineral. Results of the urinary arsenic levels are compared to those of controls. The difficulties of establishing the relationship between atmospheric arsenic and urinary arsenic are discussed, as is the place of the method among the various existing biological determination methods. Future prospects of the method, in particular by testing for uroporphyrines and coproporphyrines, are explored.

Nordic Expert Group for Documentation of Occupational Exposure Limits - 73. Arsine
Nordiska expertgruppen för gränsvärdesdokumentation - 73. Arsin (AsH3) [in Norwegian]
A survey is given of literature on arsine (AsH3), to be used as background for discussion of occupational exposure limits. Arsine is a non-irritating gas which is easily absorbed from the lungs of exposed individuals. The metal compound is rapidly concentrated in red blood cells, while the distribution into liver, kidneys and other organs appears to occur more slowly. The main excretory route is into the urine. The mechanism of the toxic actions of arsine is not fully understood. Several studies suggest that the toxicity somehow is linked to a biotransformation of AsH3 to As3+ species. It is recommended that the biological effect to be used in the discussion of exposure limits should be the haemolytic tendency (increased osmotic fragility) of red blood cells. Further studies of the toxicology of arsine are necessary, particularly in order to elucidate a possible carcinogenic effect of the compound.

Airborne arsenic and urinary excretion of metabolites of inorganic arsenic among smelter workers
The relationship between airborne concentrations of arsenic and the urinary excretion of inorganic arsenic metabolites (inorganic arsenic + methylarsonic acid + dimethylarsinic acid) was studied among smelter workers exposed to arsenic trioxide. The urinary concentrations of arsenic metabolites increased steadily during the first day of the working week (after 2-3 days off from work), after which they reached a steady state. The concentration in the late evening after a day of exposure was very similar to that in the early morning of the following day. Both were well correlated with the total daily excretion. In a second part of the study the first-void morning urine was collected for 2-3 days during the steady-state phase. Arsenic in the breathing zones was measured by personal air samplers. On a group basis, there was a good correlation between the concentration of metabolites of inorganic arsenic in urine and the concentration of airborne arsenic in the form of arsenic trioxide.

Two cases of transitional cell carcinoma of urinary tract in patients with chronic arsenic poisoning
Mansei hiso-chūdokushō kanja ni hassei shita nyōro akusei-shuyō [in Japanese]
Malignant neoplasm of the urinary tract was observed in 2 patients with chronic arsenic poisoning in Toroku district, Miyazaki Prefecture, Japan, where arsenious acid had been produced from 1920 to 1962. Each patient had a history of environmental and occupational exposure to arsenic for a long period and presented clinical manifestations of chronic arsenic poisoning. A 67-year old woman developed a skin lesion of Bowen's disease in the left scapular part and a bladder tumour, respectively 53 years and 57 years after her first exposure to arsenic. A 55-year old man developed Bowen's disease in the left lower abdomen and tumour in the left ureter, respectively 53 years and 54 years after his first exposure. In both cases surgical treatment was performed. However, excision of the tumours was impossible because of tight adhesion and infiltration into the surrounding tissues. A histological examination of the biopsy specimens of the tumours revealed transitional cell carcinoma with squamous cell metaplasia and a high degree of malignancy in each case. Some recent epidemiological data on arsenic-related cancer support the conclusion that the four malignant epitheliomas observed in these cases are due to late effects of chronic arsenic poisoning.

Arsenic levels in blood, urine, and hair of workers applying monosodium methanearsonate (MSMA)
Study of the uptake and excretion of total arsenic from monosodium methaneasonate insecticide applied by workers during the spraying season. Arsenic concentrations in breathing zone air samples ranged from 0.001 to 1.086µg/m3. Blood and urine arsenic values ranged from 0.0 to 0.2mg/L and 0.002 to 1.725mg/L respectively. The geometric mean concentration in urine increased during the week and returned to base levels on weekends. Hair arsenic concentrations ranged from 0.02 to 358mg/kg, increased during the spraying season and returned to pre-season levels once herbicide application ceased. Of the 3 workers with higher than normal pre-exposure hair values, only one had consistently above normal values throughout the study period.

Biological monitoring for heavy metals: Practical concerns
Some of the practical concerns associated with performing routine analyses of heavy metals (cadmium, lead, mercury and arsenic) in various biological matrices are the selection of the biological matrix for monitoring, the sample collection, sample storage and shipment, and sample preparation and analysis. Other factors that affect the quality of the analytical values include contamination of sampling materials, blood drawing procedures, methods of obtaining urine samples, sample homogeneity, instrument calibration and performance, and laboratory quality control programmes. A total system quality control approach is necessary to obtain accurate analyses of metals in biological samples, just as it is in all analytical situations.

An x-ray fluorescence technique to measure in situ the heavy metal burdens of persons exposed to these elements in the workplace
The use of an x-ray fluorescence technique (XRF) enables measurement of the long-term retention of various heavy metals in select tissues in vivo. XRF was used to measure the mercury content of head and bone tissue in 298 dentists with long-term exposure to mercury-containing amalgams. It was also used to evaluate the lead burden of persons suspected of having elevated lead exposure at the workplace, and to assay the lead levels in urban and rural children. These studies indicated that the x-ray fluorescence method of assaying heavy metals in vivo is noninvasive, safe, rapid, and sensitive to levels of many heavy metals that accumulate in human tissues.

Cumulative exposure to arsenic and its relationship to respiratory cancer among copper smelter employees
Study covering the respiratory cancer mortality experience (1938-1977) of 8,045 white male smelter employees in Montana, USA. When exposure was estimated with arithmetic means of measured concentrations of arsenic trioxide among men first employed prior to 1925, respiratory cancer mortality increased linearly with increasing cumulative exposure group, ranging from 2 to 9 times expected; among those first employed in the period 1925 to 1947 it also increased linearly with cumulative exposure group.

Acute encephalopathy due to occupational exposure to arsenic
Case study of a chemical engineer who developed severe psychiatric symptoms after prolonged exposure to arsenic in an antimony smelter. Though urinary and hair arsenic content were higher than normal for exposed workers, the major reason for suspecting acute arsenic intoxication was the presence of psychiatric symptoms: hallucinations, disorientation, delirium and memory loss. Because the patient had a history of psychiatric illness 28 years previously, it is suggested that he had an abnormal susceptibility to the central nervous effects of arsenic.

Rapid and specific method for the detection of trivalent arsenic
A rapid and specific method has been developed for the detection of trivalent arsenic (As). In sulphuric acid solution, As catalyses the reaction of osmium tetroxide with pyrocatechol to give a blue colour at room temperature. Many anions and cations do not interfere with the detection of As in water and gastric juice. The sensitivities were 0.25µg and 0.5µg/mL, respectively.

Arsenic exposure to smelter workers - clinical and neuro-physiological studies
Comparative study of 47 copper smelter workers exposed to arsenic for 8-40 years against a non-exposed group. The level of arsenic in workplace air was below 500µg/m3 before 1975 and about 50µg/m3 thereafter. Urine analysis showed a mean value of 71µg/L in the exposed group. Clinical studies and neurophysiological measurements showed signs of slight subclinical neuropathy. Keeping arsenic exposure below 50µg/m3 should therefore reduce the risk of neuropathy. The subclinical findings may be valuable as early indicators of exposure.

Release of arsenic from semiconductor wafers
The production of integrated circuits and other semiconductor devices requires the introduction of impurities or dopants into the crystal lattice of a silicon substrate. Inorganic arsenic, which is regulated by OSHA as a carcinogen, is frequently used as a dopant material. Silicon wafers were found to emit arsenic over a 3-5h period following ion implantation. Total amounts emitted approached 6.0µg/100 wafers processed within 4h after implantation. The implication of the potential hazard to workers is discussed.

Arsenic and inorganic compounds of arsenic in air - Laboratory method using atomic absorption spectrometry
Occurrence, uses, toxicity and first aid information are given for arsenic and its inorganic compounds. Determination method: Arsenic trioxide (in its vapour form) is collected on a paper filter treated with a sodium hydroxide solution; particulate arsenic dust and fume are collected together with arsenic trioxide or separately on a mixed cellulose ester filter; the filters are then treated with aqua regia to oxidise and dissolve the arsenic compounds; the resulting solution is analysed by atomic absorption spectrometry using the hydride evolution technique either directly or combined with the method of standard additions. Scope: suitable for sampling over periods of 10min-8h. Lower analytical limit: 0.005mg As/m3 for samples of 20L of air. Precision:<10%. The presence of many metals will cause interference, which can be eliminated by using the method of standard additions.

Epidemiologic survey of urinary arsenic levels in wine-growers handling sodium arsenite
Enquête épidémiologique sur l'arsenicisme urinaire chez des viticulteurs manipulant de l'arsénite de sodium [in French]
Study of urinary arsenic excretion in vinyard workers who use sodium arsenite as a fungicide. The general toxicity of sodium arsenite is reviewed, especially its ability to cause cancers of the skin and internal organs. Determination of urinary arsenic does not seem to be a reliable monitoring method, because it does not reflect the extent of exposure. The risk of sodium arsenite exposure could not be clearly defined; larger-scale studies are needed. Means of preventing exposure are reviewed.

Arsenic and medical surveillance
The relative worth of assessing arsenic in blood, urine, hair and nails as a measure of occupational exposure is examined. Blood levels of arsenic decline too rapidly to be useful for monitoring workers. Hair arsenic analysis may be useful on a group basis as screening device for arsenic in the environment; nail analysis has not proven useful for this type of screening. If recent seafood intake is excluded, urine is the most appropriate body fluid for evaluating worker exposure to arsenic. Because epidemiological evidence indicates that arsenic should be treated as a carcinogen; medical surveillance programmes should be developed accordingly.

Arsine in air - Colorimetric field method using silver diethyldithiocarbamate in the presence of excess silver nitrate
Occurrence, toxicity and first-aid information are given for arsine. Determination method: sampling through a midget impinger containing a solution of silver diethyldithiocarbamate, with an excess of silver nitrate, in pyridine. The magenta-coloured complex produced is compared with coloured standards. A lead acetate-impregnated cotton-wool filter traps hydrogen sulfide, preventing its interference. Scope: suitable for field use in all circumstances where the release of arsine is suspected. Analytical limits: 0.025-0.1ppm (with sampling at 1L/min over 10min), greater sensitivity for longer sampling times. Accuracy: ±0.025ppm. Some substances react with the reagent, but the colours produced are different from that of the arsine complex.

Spectrophotometric determination of arsine in air
Spektrofotometričeskoe opredelenie arsina v atmosfernom vozduhe [in Russian]
Airborne arsine is collected by drawing 20L of air at 1L/min through traps containing dilute sulfuric acid and potassium permanganate. Excess permanganate is neutralised with hydrogen peroxide, and the solution from the traps is evaporated to dryness. Arsenic present in the residue is converted to arsenic chloride and separated by liquid-liquid extraction. The extract is evaporated and treated with a reagent mixture including ammonium molybdate. The resulting blue arsenomolybdate complex is taken up in butanol, and the intensity of the colour is measured at 800nm. Colour is converted to concentration with a standard curve. The minimum measurable concentration is 0.2µg/mL in a 5mL sample, which is equivalent to 1µg of As in 20L of air.

Effects of chronic exposure to arsenate on the cardiovascular function of rats
Rats were given 50µ/ml arsenic (as sodium arsenate) in their drinking water for 320 days. After treatment there was high urinary excretion of As and considerable accumulation in the kidneys and liver, which presented slight changes. Exposed animals showed potentiation of the effects of vascular β-adrenoceptor stimulation and a reduction in vascular response to angiotensin I. The cardiovascular response suggest sympathetic hyperreactivity or hypersensitivity, or both.

Urinary arsenic, chromium, and copper levels in workers exposed to arsenic-based wood preservatives
Spot urine samples were collected from 89 wood treaters and 232 control subjects. Wood treaters averaged 103µg/l arsenic compared with 74µg/l in controls; respective figures for chromium were 41 and 63µg/l and for copper 191 and 221µg/l. Mean urinary arsenic levels of the wood treaters were within published normal limits. Urinary arsenic values can provide a useful index of occupational exposure to chromated copper arsenate wood preservatives when statistical adjustments are made for the effects of dietary arsenic.

External arsenic poisoning: effects of external contamination by arsenic dust on the skin and mucosae: 496 occupational diseases observed between 1943 and 1979 in a mispickel smelter and a review of the literature
De l'arsenicisme externe: effets de la contamination externe par les poussières arsenicales sur la peau et les muqueuses: à propos de 496 maladies professionnelles observées de 1943 à 1979 dans une fonderie de mispickel et d'une revue de littérature [in French]
Of 631 occupational diseases compensated between 1943 and 1979 in a smelter, 600 involved external arsenic poisoning due to arsenical contamination of the skin (dermatitis, sores) and the mucosae (conjunctivitis, rhinitis, perforation of the nasal septum, bronchitis). As 104 of the occupational diseases were reported imprecisely, the remaining 496 were studied with respect to the location of the lesion and the occurrence in time of 375 dermatitis cases and 95 sores. Technical and medical preventive measures are discussed.

Measurement of multiple inorganic arsenic species
Traditional sampling methods and atomic absorption analysis quantify only total inorganic arsenic. Samples collected by NIOSH during a field study at a lead-acid battery manufacuring plant were used to develop a technique capable of separating mixtures of particulate inorganic arsenic compounds and arsine and of detecting and quantifying arsenic trioxide vapour. The collection device consists of a 13mm cassette containing a cellulose-ester membrane filter without support pad and a 150mg charcoal tube connected in series. Sampling flow is 0.2l/min. It seems that, in the presence of heated arsenic sources, monitoring solely with conventional filters will underestimate arsenic exposure because of inefficient collection of arsenic trioxide vapour.
