摘要:
Firefighters may be exposed to carcinogenic agents in the smoke from fires, and there has been some concern regarding firefighters' risk of developing occupational-related cancer. Polycyclic aromatic hydrocarbons (PAHs) are present in most fires, posing a cancer risk. The objective of this study was to evaluate the PAH exposure among firefighters. Students (n = 9) and teachers (n = 4) at a firefighter training school delivered urine samples before and 6 to 7 hours after extinguishing burning diesel fuel. The urine samples were analyzed by high-performance liquid chromatography for 1-hydroxypyrene. A small but significant increase in 1-hydroxypyrene levels in the urine was found after the firefighting. This means that firefighting may cause exposure to PAHs. Although the exposure levels were low in this study, they may be different during other types of fires.

摘要:
Few studies have prospectively examined the characteristics associated with worksite adoption of tobacco-control initiatives. Data were collected as part of the Community Intervention Trial (COMMIT) for Smoking Cessation, which conducted interventions in 11 communities. This smoking cessation intervention was based on community organization principles and delivered through multiple community channels, including worksites, health care providers, the media, and cessation resources. This article reports results from telephone interviews of intervention community worksites having 50 or more employees, conducted at baseline and the end of the intervention period. Among worksites that responded to both baseline and final surveys, 83% had not adopted a smoke-free policy at baseline, and 61% did not offer any cessation aid or quitting resources at baseline. By the final survey, 34% of those with no smoking ban at baseline had become smoke-free, and 36% of those offering no cessation assistance at baseline were offering cessation resources at the follow-up. The prevalence of policy adoption was higher among worksites employing more female employees and offering other health-promotion activities; manufacturing businesses were significantly less likely than businesses other than service and wholesale/retail businesses to adopt policies. Adoption of cessation programs was significantly more likely among worksites employing 100 to 249 workers, compared with those employing 50 to 99 workers; those predominantly employing men; those offering other types of health-promotion activities; and those with a higher rate of turnover. These results provide important information about the characteristics of worksites likely to engage in tobacco-control efforts. Health educators and others may choose to target those worksites most ready for adoption of tobacco control policies and programs, as indicated by these findings.

摘要:
Coke oven and by-product workers are potentially exposed to coke oven emissions (COE), which contain hundreds of chemicals and are primarily composed of polycyclic aromatic hydrocarbons (PAH) and volatile organic compounds. Some of these compounds are hepatotoxins. The objective of this study was to examine the relationship between work in coke oven and by-product plants and serum activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), the most commonly performed liver-function tests. The exposed group was composed of current workers who had been employed at least 3 months in the two coke-operation work areas, including one coke oven plant and one by-product plant (Area I: n = 117; Area II: n = 96) of a large steel company in Taiwan. Control subjects (Area III: n = 131), not visiting either coke-operation area in the last 3 months, were collected from the administrative and nonproduction areas in the same company. PAH exposure, as a surrogate of COE, was measured monthly by PM-10 size-selective high-volume-area air samplers in or around these three areas between June and December 1990, as well as between November 1992 and June 1993. The mean total respiratory particulate PAH exposure levels (<10 µm) between November 1992 and June 1993 in Areas I, II, and III were 6.8 × 103, 2.1 × 103, and 6.5 × 101ng/m3, respectively. AST, ALT, and hepatitis B surface antigen tests were performed in 1994. Workers who showed either AST or ALT levels greater than reference levels (abnormal >25 IU/L) were regarded as showing "elevated liver enzyme levels." Workers in Area I had AST levels that were 17% higher (95% confidence interval [CI], 3% to 32%]) and ALT levels that were 35% higher (95% CI, 10% to 65%)] than those in Area III after controlling for appropriate confounders. The adjusted odds ratio (Area I vs Area III) for elevated liver enzymes was 4.4 (95% CI, 1.5 to 13.4). In addition, coke oven (n = 91) and by-product workers (n = 26) from Area I had ALT levels 37% and 45% higher, respectively, compared with control subjects from Area III, after adjusting for appropriate confounders. Similar effects are also seen for AST. Workers in Area II had slightly, but not significantly, elevated AST and ALT levels. These results indicate that workers most heavily exposed to COE exhibit elevated aminotransferase levels.

摘要:
We carried out a retrospective cohort study using a self-administered questionnaire to assess the risk of hairdressers to develop asthma and chronic bronchitis. A representative sample of 4433 female hairdressers and an equal number of shop personnel in employment in 1980 was drawn from the Longitudinal Census Data File of Statistics Finland. Physician-diagnosed asthma, chronic bronchitis, and other respiratory diseases in 1980 and 1995 were inquired about in the respiratory part of the questionnaire. The response rate to the questionnaire was 82% for the hairdressers (n = 3484) and 79% for the referents (n = 3357). The prevalence of asthma among the hairdressers was 5.6% in 1980 and 10.1% in 1995, and the prevalence of chronic bronchitis was 3.9% in 1980 and 5.6% in 1995. The relative risk for asthma (odds ratio [OR]: 1.7, 95% confidence interval [CI]: 1.3 to 2.3 in 1980; and OR: 1.7, 95% CI: 1.4 to 2.2 in 1995) and for chronic bronchitis (OR: 2.2, 95% CI: 1.5 to 3.2 in 1980; and OR: 1.9, 95% CI: 1.4 to 2.6 in 1995) among hairdressers was almost twice that in the reference group. The incidence rate of asthma in 1980 through 1995 was 2.2 and of chronic bronchitis was 1.1 cases per 1000 person-years among hairdressers, whereas the rate in the reference group was 1.3 asthma cases and 0.9 chronic bronchitis cases per 1000 person-years. The relative risk for developing asthma during the 15 years' observation time was 1.7 (95% CI: 1.1 to 2.5) and for chronic bronchitis was 1.2 (95% CI: 0.7 to 1.9) among hairdressers, compared with referents. Our results indicate that hairdressers are at higher risk for developing asthma.

摘要:
Chronic beryllium disease (CBD) diagnosis hinges on demonstrating a cell-mediated immune response to beryllium salts in vitro with the beryllium lymphocyte proliferation test (BeLPT). The BeLPT has found widespread application in screening for CBD and beryllium sensitization in populations of exposed workers. We hypothesized that the in vivo beryllium salt patch test may be of value as an adjunct to the BeLPT, rectifying false negative or ambiguous blood test results. We studied subjects with CBD (n = 11), beryllium sensitization without disease (n = 3), and control subjects with dermatitis (n = 20). Evaluation included completion of a demographic questionnaire, blood BeLPT (if CBD or beryllium-sensitized), and beryllium patch testing with 0.1% and 1% beryllium sulfate (BeSO4) in petrolatum and in aqueous vehicles. Biopsies were performed at abnormal patch test sites in five subjects. The 1% aqueous BeSO4proved superior either to 1% petrolatum or 0.1% solutions, producing positive reactions in all CBD and beryllium-sensitized subjects. We observed no long-term adverse reactions. Biopsies demonstrated spongiotic changes early, followed by noncaseating granulomas within 18 days. We conclude that the beryllium patch test can be used safely to clarify the sensitization state and diagnosis of CBD.

摘要:
An historical cohort mortality study was undertaken at Owens Corning's continuous filament fiberglass manufacturing plant in Anderson, South Carolina. The cohort included 1074 white women, 130 black women, and 494 black men who worked for a minimum of one year from the opening of the plant in 1951 through December 31, 1991. This represents the largest single cohort of white women assembled to date in either a wool or continuous filament fiberglass manufacturing facility and represents the first study of a cohort of black men and women in the man-made vitreous fiber industry. Over 95 % of the women and minorities included in this report held production positions in the plant. There were no significant excesses or deficits in mortality by cause, including cancer causes, among white women, with the exception of motor-vehicle accidents, when compared with national mortality. Among black men, standardized mortality ratios (SMRs) for heart disease are significantly below one, and SMRs for all cancers combined are below unity on both national and local standards. Lung cancer SMRs are below unity for both white women and black men.

摘要:
We studied the prevalence and relationship of stress and working conditions with adverse reproductive outcomes in a cohort of female US law-school alumnae. A total of 584 female lawyers (74% response), aged 25 to 63, responded to a mailed questionnaire. Job hours per week was a strong predictor of job stress. In a logistic regression analysis, women working >45 hours/week were five times as likely to report high stress as those working <35 hours/week. Marriage and length of time on the job showed a small inverse association with stress. Women who worked more than 45 hours/week during their first trimester of pregnancy were more likely to report high stress at work during pregnancy. After being adjusted for confounding factors, weekly job hours during the first trimester of pregnancy showed a strong independent association with spontaneous abortion risk (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.4 to 6.6). Seven or more alcohol drinks/week was also independently associated with spontaneous abortion risk (OR, 4.8; 95% CI, 1.5 to 18.1). Self-reported stress during pregnancy was positively but not statistically significantly associated with spontaneous abortion (OR, 1.4; 95% CI 0.8 to 2.3).
