Exposure of Russian phenoxy herbicide producers to dioxins
Blood samples of workers who worked during the 1960s at a phenoxy herbicide plant in the Bashkortostan region of Russia were collected in 1992 and analysed by GC-MS. 34 workers who manufactured 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) had median blood lipid 2,3,7,8-tetrachlorodibenzo p-dioxin (TCDD) concentrations of 166ng/kg and 1,2,3,7,8-pentachloro-p-dioxin (PnCDD) levels of 52ng/kg. These values are 10 to 30 times higher than contemporary normal levels from the Bashkortostan region and were at least 10-fold higher in the 1960s. Six workers who produced the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) also had elevated levels in 1992, with PnCDD levels higher than those of TCDD. Children of some of the workers and factory administrative personnel also had blood levels of TCDD higher than most general population groups from other parts of Russia or from other countries. No correlation was found between chloracne status in 1965 to 1967 and TCDD or toxic equivalent blood lipid concentrations in 1992. These phenoxy herbicide workers appear to have some the highest dioxins levels of any cohort studied to date.

Development of a versatile method for the detection of nicotine in air
Nicotine is present in environmental tobacco smoke and is used as a greenhouse insecticide. Exposure to nicotine can result in adverse health effects as nausea, vomiting, headache, dizziness, tachycardia, hypertension, convulsions and cardiac arrhythmia. This paper describes the development of an improved sampling and analytical methodology for nicotine, capable of accommodating the wide spread of nicotine levels and sampling requirements necessary to evaluate exposures among diverse occupational groups such as casino workers, airline flight attendants or greenhouse employees. A XAD-4 sorbent tube was selected for the collection of airborne nicotine. Analytical methodology for the separation, identification and quantification of nicotine by gas chromatography followed by either flame ionization detection or by nitrogen and phosphorous detection is described. This new method was published in the NIOSH Manual of Analytical Methods.

Biological monitoring of N-methyl-2-pyrrolidone using 5-hydroxy-N-methyl-2-pyrrolidone in plasma and urine as the biomarker
To study the toxicokinetics of 5-hydroxy-N-methyl-pyrrolidone (5-HNMP) in blood and urine after exposure to N-methyl-2-pyrrolidone (NMP) and the suitability of 5-NMP as a biomarker for assessing the NMP exposure, six male volunteers were exposed for 8 hours to NMP concentrations of 0, 10, 25 and 50mg/m3. Blood and urine were sampled before, during, and up to 40 hours after the exposure. The plasma concentrations after 8-hour NMP exposure to 10, 25, and 50mg/m3 were 8.0, 19.6, and 44.4mmol/L, respectively, and the urinary concentrations for the 2 last hours of exposure were 17.7, 57.3 and 117.3mmol/mol creatinine, respectively. The 5-HNMP urinary concentrations were 58% of the calculated retained dose. There was a close correlation between plasma and urinary 5-HNMP with NMR exposure, making 5-HNMP suitable for monitoring exposure to NMP.

Airborne contact dermatitis from methylchloroisothiazolone in wall paint. Abolition of symptoms by chemical allergen activation
Preservatives such as isothiazolinones in paints have been reported to cause airborne contact dermatitis. Cases from five patients who experienced acute dermatitis on air-exposed skin and respiratory symptoms after staying in recently painted rooms are reported. Kathon® (a mixture of methylchloroisothiazolinone and methylisothiazolinone) added as preservative to the wall paint was identified as the causative agent. In one person, symptoms rapidly disappeared after treatment of the painted walls with sodium bisulfite which leads to inactivation of the allergenic properties of Kathon®. Chemical analyses of the decorating paints used and experiments on emission and air concentration of Kathon® from a painted surface before and after inactivation by sodium bisulfite are also described.

The effects of dioxin on reproduction and development
Review article. The developmental effects of dioxin are important because of the high sensitivity of mammals to the substance as well as the irreversibility and longevity of the effects. In animal experiments, exposure to dioxin during pregnancy and lactation induces various functional effects on offspring at very low doses. In humans, even if there is no exposure to dioxin after birth, there might be effects on thyroid function in infants exposed to dioxin from breast milk. In this report, low-dose developmental effects of dioxins on offspring in animal experiments, as well as in human studies, are reviewed. Dosimetry, dose-response models and approaches to health risk assessment are discussed.

Environmental health in the east Baltic region - Pesticides and persistent organic compounds
Exposure to, and the potential effects of, pesticides and persistent organic pollutants in the East Baltic region are reviewed. Exposure of the average population to chlorinated compounds seems lower than in most of western Europe and current pesticide use is very low. The low exposure of the general population is indicated by low concentrations of polychlorinated dibenzo-p-dioxins, dibenzofurans and biphenyls in milk fat. However, some organic pesticides have been found at higher concentrations in Baltic countries and the St Petersburg area than in Norway. Thus the overall risk caused by pesticide residues and persistent organic compounds in the Baltic countries and northwestern Russia is low, but local sites of concern exist.

A cross-sectional study of workers in the chemical industry with occupational exposure to hexamethylenetetramine
To assess the health effects of hexamethylenetetramine (HMT) on the airways and skin of workers in the chemical industry, a cross-sectional study was performed with 17 employees of a HMT-producing chemical plant and 16 control subjects from the plant, as well as 4 subjects who had left the production for medical reasons. A high proportion of exposed subjects and controls reported symptoms during the previous year, most of them were not related to work. Work-related symptoms and objective parameters did not show differences between groups. No cases of sensitization to HMT as assessed by skin prick tests or patch tests were found. Among those who had left the HMT production for medical reasons, 2 former workers showed sensitization to HMT by patch tests. These reported eczema during exposure but lost symptoms after removal from exposure. High exposures to HMT may cause allergic contact dermatitis. There was no evidence of an increased risk for occupational asthma.

Mortalities of workers at the Nitro plant with exposure to 2-mercaptobenzothiazole
A cohort study of workers exposed to 2-mercaptobenzothiazole (MBT) at a rubber chemicals plant in Nitro (West Virginia) examines the mortalities of 1,059 full-time white male production workers employed at the plant from 1955 to 1977. A detailed exposure assessment was done on the 600 workers with exposure to MBT. It was found that MBT workers have expected rates of lung and prostate cancer. There was an excess of bladder cancer among MBT workers who had definite exposure to 4-aminobiphenyl (PAB), and MBT workers with potential exposure to PAB. However, there were no deaths from bladder cancer among workers with no exposure to PAB, although there were only 0.2 deaths expected. The potential confounding of exposure to PAB an unknown portion of in the MBT workers makes it impossible to evaluate risk of bladder cancer in this population at this time. However, exposure to MBT does not seem to increase the risk of most cancers including cancers of the lung and prostate.

Evaluation of diabetes mellitus, serum glucose, and thyroid function among United States workers exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin
A cross-sectional study of workers employed >15 years earlier in the manufacturing of 2,4,5-trichlorophenol or one of its derivatives at two United States chemical plants was conducted. The control group consisted of people with no occupational exposure to phenoxy herbicides and were recruited from the neighbourhoods where the workers lived. A total of 281 workers and 260 unexposed controls participated. Overall, the prevalence of diabetes mellitus was not significantly different between the workers and controls. Also, there was not a significant positive trend between prevalence of diabetes and increasing serum 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) concentration. However, diabetes was found in six of ten workers. After excluding subjects being treated for diabetes, workers in the group with the highest extrapolated half-life TCDD concentrations had a significantly increased adjusted mean serum glucose concentration compared with controls. Workers were also found to have a significantly higher adjusted mean free thyroxine index than the controls, especially among workers in the group with the highest extrapolated half-life TCDD concentrations. However, no evidence was found for the relationship between exposure to TCDD and an increased risk of thyroid disease.

Urinary cotinine concentration in flight attendants, in relation to exposure to environmental tobacco smoke during intercontinental flights
24 cabin attendants (C/A) and one pilot, all non-smokers and without exposure to environmental tobacco smoke (ETS) in the home, were studied in order to measure and compare urinary cotinine concentration (U-cotinine) before, during and after work on intercontinental flights with exposure to ETS. Information on age, gender and occupation was gathered, as well as possible sources of ETS exposure in other places, outside work and during previous flights, during a 3-day period prior to the investigation. Urine samples were taken before departure, on board, and after landing. The median U-cotonine was 3.71µg/g crea before departure and 6.37µg/g crea after landing. Tobacco smoking in commercial aircraft may cause significant exposure to ETS among C/A working in the aft galley, despite high air exchange rates and spatial separation between smokers and non-smokers. Since smoking in commercial aircraft may result in an involuntary exposure to ETS among non-smokers, it should be avoided.

Assessment of the cancer risk from exposure to dioxins
Krebsrisikoabschätzung für Dioxine [in German]
The cancer risk of the general population in Germany due to a lifetime exposure to polychlorinated dibenzodioxins and dibenzofurans (PCDD/PCDF) in concentrations found in the environment today was assessed. The data of a case control study of the cancer mortality among workers in a chemical plant in Hamburg, Germany, with high exposure to PCDD/PCDF were used as a base. The case-control study yielded a nearly linear dose-response relationship between 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) or the toxicity equivalent TEQ in pg/kg blood fat and cancer. In the study the cancer mortality among 1,189 chemical workers and the involved exposure doses were determined and compared with a control group of 2,518 workers in a gas company. For ambient concentrations of TCDD of 8.7fg/m3 in metropolitan areas and 1.3fg/m3 in rural areas an average cancer risk for the population in Germany of 1.7 cases per million was derived.

Assessment of environmental tobacco smoke and respirable suspended particle exposures for nonsmokers in Prague using personal monitoring
Air samples were collected from the breathing zone of nonsmokers wearing personal monitors for 24h. Samples were analysed for respirable suspended particles, nicotine, 3-ethenylpyridine and environmental tobacco smoke (ETS) particles. Saliva cotinine analyses were also undertaken to confirm the nonsmoking status of the subjects. Highest exposures were apparent for office workers both working and living in smoking environments. Findings suggest a significant contribution to overall ETS particle and nicotine levels from the workplace where smoking takes place. Topics: airborne dust; cotinine; nicotine; Czech Republic; determination in air; determination in saliva; exposure evaluation; passive smoking; personal sampling; respirable dust.

Respiratory symptoms, spirometry and chronic occupational paraquat exposure
In a study of 134 workers exposed to paraquat at 15 Nicaraguan banana plantations, 53% reported having experienced a skin rash or burn resulting from paraquat exposure, 25% reported epistaxis, 58% nail damage and 42% paraquat splashed in the eyes. There was a consistent dose-response relationship between intensity of exposure and the prevalence of dyspnoea. There was a three-fold increase in episodic wheezing accompanied by shortness of breath among the more intensely exposed workers. The high prevalence of respiratory symptoms associated with paraquat exposure, in the absence of spirometric abnormalities, could be a result of unmeasured gas exchange abnormalities among workers with long-term exposure to paraquat. Topics: chemical burns; crop protection; cross-sectional study; dose-response relationship; dyspnoea; functional respiratory disorders; long-term exposure; nail diseases; Nicaragua; paraquat; plantations; respiratory diseases; skin eruption; ventilatory capacity.
