Triglycidyl isocyanurate (and coating powders containing triglycidyl isocyanurate) in air
A method is described for the analysis of time-weighted average concentrations of triglycidyl isocyanurate (TGIC) and premix and coating powders containing TGIC in air. Principle: a measured volume of air is drawn through a silanized glass fibre filter mounted in an inhalable dust sampler; the sample is extracted using one of two methods depending on whether TGIC is present in air alone or in a premix or coating powder; the resulting solution is analyzed by high performance liquid chromatography with a UV detector. The method is validated between 0.01 and 0.2mg/m3 pure TGIC for sample volumes of 200L. The detection limit for TGIC is typically around 0.18µg per sample (0.9µg /m3 for a 200L volume air sample).

Stillbirth after exposure to N-methyl-2-pyrrolidone
This letter is in reply to a previous case report of a stillbirth following occupational exposure to N-methyl-2-pyrrolidone (NMP) (see CIS 96-1777). The producers of the chemical do not agree with the authors' line of reasoning that links a single stillbirth with an exposure to NMP. They also argue that inaccuracies in the review of animal toxicological data in the article could cause concerns among users of NMP who may consider themselves to be at risk. A reply by the original authors is presented.

Occupational asthma and rhinitis caused by 1,2-benzisothiazolin-3-one in a chemical worker
A worker in a chemical factory producing detergents complained of rhinitis and asthma two months after starting a job in which he was exposed to 1,2-benzisothiazolin-3-one, a microbicidal additive. The specific challenge test with this substance provoked an immediate prolonged asthmatic response and nasal symptoms. This is the first known case of occupational asthma and rhinitis caused by this compound.

Criteria and methods for the study of occupational exposure to antineoplastic drugs
Criteri e metodi per lo studio dell'esposizione occupazionale a chemioterapici antiblastici [in Italian]
Risk assessment and exposure evaluation of antineoplastic drugs are discussed from the point of view of environmental and biological monitoring. The problems of exposed health workers (pharmacists and nursing personnel) are emphasized. Guidelines are proposed on the basis of a check list adopted in some Italian hospitals. Work rooms, procedures, types and quantities of drugs and preventive measures must be monitored according to a standardized data collection scheme. Determination of cyclophosphamide, 5-fluorouracil and platinum coordination compounds used as tracers of drug mixtures is recommended in Italian hospitals. In annex: questionnaire for the evaluation of exposure to antineoplastic drugs; analytical methods for the determination of commonly used antineoplastic drugs.

Occupational exposure of nonsmoking nightclub musicians to environmental smoke
Exposure to environmental tobacco smoke (ETS) in three nightclubs was assessed using total suspended particulate (TSP), the ultraviolet absorbing fraction of TSP (UVPM), gaseous nicotine, saliva nicotine, saliva cotinine, and perceived smokiness as exposure/dose indicators. Measured exposures were as high as, or higher than, those of other occupational groups studied, including bartenders and waitresses. UVPM levels were associated with gaseous and saliva nicotine concentrations. Correlation of TSP with UVPM and with gaseous and saliva nicotine was poor, suggesting that TSP should not be used as the sole indicator of ETS exposure. Saliva nicotine did not appear to be a reliable indicator of absorbed dose.

Pesticide application and increased dioxin body burden in male and female agricultural workers in China
Following large-scale spraying of the pesticide sodium pentachlorophenol (Na-PCP) salt over agricultural and lake areas in China in the 1970s, dioxin levels were determined in sprayers or handlers of Na-PCP, and in persons living in sprayed and non-sprayed areas. Blood and breast-milk samples were collected and pooled for dioxin analysis, and samples of lake sediment were analyzed. Levels of polychlorinated dibenzodioxins and dibenzofurans (PCDD/F) in human tissue were found to be low in China compared with more industrialized countries. However, environmental and human tissue samples from sprayed areas had PCDD/F levels and international dioxin toxic equivalent (I-TEQ) levels several times higher than those from non-sprayed areas.

Exposure to polybrominated dibenzofurans and dibenzodioxins in copper smelting plants and in the production of flameproofed plastics
Belastung durch polybromierte Dibenzofurane und -dioxine in Sekundärkupferhütten und bei der Herstellung flammgeschützter Kunststoffe [in German]
Exposure to polybrominated dibenzodioxins (PBDD) and dibenzofurans (PBDF) was determined at selected workplaces in two scrap metal smelting plants and three plants producing flameproofed plastics in Germany. The smelting plants were chosen because they also process copper-containing scrap with small amounts of plastics. In the plants producing flameproofed plastics, samples of flame retardants applied in flameproofing as well as samples of flameproofed plastics were analyzed for the presence of PBDD and PBDF in addition to air samples. In the air samples the concentrations of mono- to hexabromodibenzofurans ranged from 258 to 77,414pg/m3. Most of the air samples contained PBDD and PBDF with bromine at positions 2, 3, 7 and 8. None or very low concentrations of these compounds were detected in the flame retardants and in the flameproofed plastics samples as well as in all samples that were analyzed in the scrap metal smelting plants.

Tobacco, caffeine, alcohol and carpal tunnel syndrome in American industry - A cross-sectional study of 1464 workers
The effects of legal drug use on the prevalence of carpal tunnel syndrome (CTS) were studied in 656 nonclaimant workers and 808 working patients with upper extremity symptoms. Greater use of tobacco combined with greater consumption of caffeinated beverages and alcohol abuse was associated with more median nerve slowing, more specific hand/wrist symptoms, and more definite CTS as confirmed by nerve conduction studies. Greater use of alcohol was associated with a reduced prevalence of symptoms. While legal drugs affect the health of the median nerve and the prevalence of CTS, their effects explain only a small portion of the total risk.

Familial clusters of green tobacco sickness
Three case studies are presented of clusters of three to five members of an immediate or extended family who became ill after working together on tobacco farms in Kentucky, USA. Symptoms included vomiting, nausea, weakness, dizziness, pallor, headache and diaphoresis. Factors contributing to the clustering of green tobacco sickness in this area include the predominance of family-based work crews, manual harvesting methods involving considerable dermal contact with the tobacco plants, and the high nicotine content of the tobacco.

Atrazine and/or triazine herbicides exposure and cancer: An epidemiologic review
Ten case studies concerning exposure to atrazines and/or triazines and cancer in occupational (agricultural) settings are summarized. Based on the limited data available, there is no convincing evidence of a causal association between atrazine and/or triazine and colon cancer, soft tissue sarcoma, Hodgkin's disease, multiple myeloma or leukaemia. There is a suggestion of a possible association between these compounds and ovarian cancer and non-Hodgkin's lymphoma. While animal studies indicate that atrazine is a potential human carcinogen, current epidemiologic evidence is not conclusive.

Stillbirth after occupational exposure to N-methyl-2-pyrrolidone - A case report and review of the literature
A case report is presented of a pregnant laboratory technician who suffered intrauterine growth retardation and stillbirth following exposure to N-methyl-2-pyrrolidone. Animal studies have demonstrated that this solvent is embryotoxic after maternal exposure to doses that have minimal or no adverse effect on the mother. Laboratory work and solvent exposure have both been previously associated with adverse reproductive outcomes. Laboratory health policies should allow for voluntary removal of prospective parents in situations of possible exposure.

Dioxin concentrations in the blood of workers at municipal waste incinerators
Increased concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzo-furans (PCDFs) in pooled blood samples from workers at municipal waste incinerators have been reported. With a view to confirming these results, concentrations of PCDDs and PCDFs were determined in the blood of 10 workers from an old municipal waste incinerator without adequate pollution controls, 11 workers from a newer incinerator with modern pollution controls and 25 controls from the general population group. PCDD and PCDF concentrations were determined as well in the slag and fly ash from the older incinerator. Significant increases of certain PCDDs and PCDFs were found in the blood of the workers from the older incinerator compared with the controls. The pattern of increased PCDDs and PCDFs in the blood corresponded to the pattern in the incinerator slag and ash. Modern pollution control technology in new incinerators may be able to minimize potential exposure to slag and fly ash and thus the absorption of PCDDs and PCDFs from this source.

Occupational exposure to environmental tobacco smoke
A survey was carried out to measure the average weekly concentration of environmental tobacco smoke in 23 worksites in Massachusetts, USA. Approximately 25 samplers were placed in each worksite for a week. Nicotine concentrations fell from a median of 8.6µg/m3 in the open offices at worksites that allowed smoking to 1.3µg/m3 in sites that restricted smoking, and to 0.3µg/m3 in worksites that banned smoking. Non-office workspaces were similarly affected. Results indicate that occupational exposure to environmental tobacco smoke presents a substantial risk to workers in the absence of a policy restricting or banning smoking.

Conclusions of these criteria documents, translation of reports finalized in June-Dec. 1992: no data are available on the acute or chronic effects of melamine in man; tests for irritating or sensitizing properties proved negative. Animal studies indicate that diisopropanolamine (1,1'-iminodi-2-propanol) is of low acute toxicity; tests on humans reveal that it does not induce allergic or photoallergic reactions. No data are available on the effects of 1,6-hexanediol in man; animal studies indicate a slight acute toxicity. Tributyl phosphate is strongly irritating to the skin and mucous membranes in man; exposure by inhalation leads to nausea and headache. The toxicological action of dibutyl phosphate is assumed to be comparable to that of tributyl phosphate.

Dioxin contamination in Seveso: The social tragedy and the scientific challenge
Paper presented at the 10th International Symposium on Epidemiology in Occupational Health (Como, Italy, 20-24 Sep. 1994). Essentially a literature survey, it describes the Seveso accident (10 July 1976), in which the highly toxic substance 2,3,7,8-tetrachlorodibenzodioxin (TCDD) was released into the environment. The immediate aftermath of the accident is surveyed. The results of subsequent exposure assessment measurements are given (the most heavily contaminated area, in the immediate vicinity of the factory where the accident occurred, had mean soil levels of TCDD ranging 15.5-580µ/m2). Human exposure and dose data near the factory are also provided. The health effects of the accidents, as shown by mortality and cancer morbidity studies, are surveyed. Finally, comments are made regarding the scientific challenge provided by the aftermath of the accident. It seems that despite the serious nature of the accident, no clear-cut conclusion can be made that TCDD exposure has produced a significant increase in cancer incidence in the Seveso area.

Criteria documents from the Nordic Expert Group 1994
Kriteriedokument från Nordiska Expertgruppen 1994 [in Swedish]
The Nordic Expert Group is a standing committee with the task of producing criteria documents on health effects of occupationally used chemicals. The documents are meant to be used by the regulatory authorities in the five Nordic countries as a scientific basis for the setting of national occupational exposure limits. This volume consists of translations into a Scandinavian language (Danish, Norwegian or Swedish) of the criteria documents which were published in English during 1994. The documents concern: 1,3-butadiene (CIS 97-954), cobalt and cobalt compounds (CIS 97-955), diethylamine, diethylenetriamine, dimethylamine, ethylenediamine, 2-ethylhexanoic acid, industrial enzymes (CIS 97-953), N-methyl-2-pyrrolidone (NMP)(CIS 97-956).

The Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals. 115. N-Methyl-2-pyrrolidone (NMP)
A critical survey and evaluation of the relevant literature, to be used as a basis for establishing an occupational exposure limit for N-methyl-2-pyrrolidone (NMP). NMP is a widely and increasingly used solvent. The toxicity of NMP is, however, not well known. The observed irritant effects on skin and eyes are those of a moderate to severe irritant. Subchronic exposure to NMP may cause degenerative tissue changes and affect the respiratory, haemopoietic and lymphoid system. Lethargy and irregular respiration observed after both inhalation and oral administration may be due to a neurotoxic effect. NMP seems to be a weak mutagen. For evaluation of the carcinogenic potential, further data are needed. Reproductive toxicity studies in rabbits, rats and mice show developmental toxicity at doses causing no or mild maternal toxicity. Prenatal exposure to NMP may cause postnatal neurobehavioural effects in rats. The critical effect of NMP in occupational exposure is irritation of the eyes and skin. Another critical effect of NMP may be its enhancing effect on skin penetration by other compounds.

The role of biotransformation in assessing the toxicological risk from pesticides
Ruolo della biotrasformazione nella valutazione del rischio tossicologico da pesticidi [in Italian]
The knowledge of metabolic processes and the measurement of metabolites of pesticides are fundamental for the evaluation of their toxic effects and of their persistence in the environment and biological tissues. In this review atrazine is discussed as an example of an environmental pollutant undergoing biotransformation processes.

Porphyrin studies in TCDD-exposed workers
2,3,7,8,-Tetrachlorodibenzo-p-dioxin (TCDD) has been shown to inhibit uroporphyrinogen decarboxylase activity resulting in chronic hepatic porphyria. From a cross-sectional study of 170 workers in the chemical industry 68 showed elevated coproporphyrin levels, interpreted as secondary coproporphyrinuria. Three persons suffered from chronic hepatic porphyria in subclinical stages. None of the workers showed an overt porphyria cutanea tarda. A low-grade zinc protoporphyrinaemia was observed in three persons. Forty-three of the 170 workers were evaluable for investigating the effect of TCDD on porphyrin levels. No significant correlation was found between TCDD concentration in adipose tissue and the level of uroporphyrin and coproporphyrin. The influence of a chloracne history is described.

Biological monitoring of cyclophosphamide and ifosfamide in urine of hospital personnel occupationally exposed to cytostatic drugs
The occupational exposure of 21 nurses and pharmacy personnel from eight hospitals to cyclophosphamide and ifosfamide was determined by quantifying the amount of the drugs handled and by measuring the urinary excretion of the unmetabolized substances. Twenty-four hour urine was collected on days when cyclophosphamide and/or ifosfamide were mixed, on average 3,900mg cyclophosphamide and/or 5,900 mg ifosfamide. The analyses were performed by gas chromatography with electron capture, detection limit 2.5µg/24-h urine. Based on an excretion rate of 11.3% unmetabolized cyclophosphamide, the average amount excreted corresponded to an uptake of 101µg cyclophosphamide. For ifosfamide the mean quantity incorporated was 20µg assuming that 45% of the drug was excreted. Despite time-consuming purification procedures, gas chromatographic analysis is a suitable method for monitoring personnel occupationally exposed to cyclophosphamide and ifosfamide and is a major contribution to the evaluation of potential health risks of exposed personnel.

Occupational exposure to isothiazolinones. A study based on a product register
The Danish Product Register (PROBAS) was searched in order to survey occupational exposure to isothiazolinones. Mixtures of 2-methyl-4-isothiazolin-3-one and its 5-chloro derivative (MI/MCI) were registered in 550 products; 1,2-benzisothiazolin-3-one (BIT) in 156 products; and 2-n-octyl-4-isothiazolin-3-one in 16 products. Main product categories were paints, hair shampoos, skin care products, cleaning agents and polishes. While the dermatological literature has often focused on isothiazolinones in cosmetics as a source of allergy, the present study shows that attention should also be paid to occupational exposure, as isothiazolinones also occur in many industrial product categories.

Cutaneous reactions due to pyridinecarboxaldehyde, thiophenecarboxaldehyde - Isomerism
Réactions cutanées aux pyridinecarbaldéhydes et thiophènecarbaldéhydes - Notion d'isomérie [in French]
A 27-year-old woman who underwent skin exposure to pyridinecarboxaldehyde and thiophenecarboxaldehyde at the workplace. In patch tests, 3-pyridinecarboxaldehyde produced urticaria whereas 2-pyridinecarboxaldehyde isomer induced eczema and no reaction was observed with 4-pyridinecarboxaldehyde. Patch tests made with thiophenecarboxaldehyde showed that the patient was sensitive to 3-thiophenecarboxaldehyde, which induced irritant erythema whereas there was no reaction with its isomer 2-thiophenecarboxaldehyde. Thus, depending on the position of the carbonyl carbon on the pyridine (ortho, meta or para) or thiophene ring, different reactions can occur.
