A retrospective cohort study of 14,457 workers at an aircraft maintenance facility was undertaken to evaluate mortality associated with exposures in their workplace. The purpose determine whether working solvents, particularly trichloroethylene, posed any excess risk mortality. group consisted all civilian employees who worked for least one year Hill Air Force Base, Utah, between 1 January 1952 and 31 December 1956. Work histories were obtained from records the National Personnel Records...
OBJECTIVES: To evaluate the risk of cancer and other diseases among workers engaged in aircraft manufacturing potentially exposed to compounds containing chromate, trichloroethylene (TCE), perchloroethylene (PCE), mixed solvents. METHODS: A retrospective cohort mortality study was conducted employed for at least 1 year a large facility California on or after January 1960. The experience these determined by examination national, state, company records end 1996. Standardised ratios (SMRs) were...
Although titanium dioxide (TiO2) is generally regarded as a nontoxic mild pulmonary irritant, some laboratory studies have reported lung adenomas in rats exposed to high levels of TiO2. Limited data on health effects among humans exist. A retrospective cohort mortality study was conducted 4241 TiO2 workers who were employed for at least 6 months, or after January 1, 1960, four plants the United States. Exposure categories, defined by plant, job title, and calendar years job, created examine...
Hexavalent chromium (CrVI) is known to cause lung cancer among workers exposed high concentrations in certain historical industries. It also a toxic air contaminant considered pose potentially significant risk at comparatively low urban air. However, very limited data currently exist quantify low-concentration occupational or environmental exposures. This study reconstructs individual-level exposures using job-exposure matrix (JEM) and examines mortality 3,723 CrVI-exposed aircraft...
Methods are presented that were used for assessing exposures in a cohort mortality study of 15,000 employees who held 150,000 jobs at an Air Force base from 1939 to 1982. Standardisation the word order and spelling job titles identified 43,000 unique title organisation combinations. Walkthrough surveys conducted, long term interviewed, available industrial hygiene data collected evaluate historic exposures. Because difficulties linking air monitoring use specific chemicals departments work...
Objective: The objective of this study was to evaluate potential health risks associated with testing rocket engines. Methods: A retrospective cohort mortality conducted 8372 Rocketdyne workers employed 1948 1999 at the Santa Susana Field Laboratory (SSFL). Standardized ratios (SMRs) and 95% confidence intervals (CIs) were calculated for all workers, including those specific test areas where particular fuels, solvents, chemicals used. Dose–response trends evaluated using Cox proportional...
Extended cancer follow-up among 77,943 aircraft workers.Comprehensive exposure information enabled detailed classification of trichloroethylene (TCE), perchloroethylene (PCE), mixed solvents, and chromates these workers.Exposure to TCE, PCE, solvents or was not associated with increased risk overall for most sites. Elevated rates compared the general population were seen non-Hodgkin lymphoma PCE exposure, colon testicular cancers multiple myeloma exposure. Internal cohort analyses, however,...
In Brief Objective: To evaluate potential cancer risks in the US semiconductor wafer fabrication industry. Methods: A cohort of 100,081 workers employed between 1968 and 2002 was studied. Standardized mortality ratios relative (RRs) were estimated. Results: similar significantly low among nonfabrication for all causes (0.54 0.54) cancers (0.74 0.72). Internal comparisons also showed overall (RR = 0.98), including process equipment operators service technicians (OP/EST) cleanrooms 0.97),...
Objective: To classify 100,081 semiconductor workers employed during 1983–2002, and some as early 1968, regarding potential for chemical exposures in cleanrooms silicon wafer fabrication. Methods: This study involved site visits to 10 cities with fabrication facilities, evaluation of 12,300 personal air samples >60 chemicals, examination >37,000 departments >8600 job codes develop exposure groupings. Results: Each worker was classified into one five groups on the basis job-department...
Methods were developed to assess exposure a wide variety of chemicals for nearly 80,000 workers involved in manufacturing aircraft since 1928. The facilities, now closed, consisted four major plants, over 200 buildings, and changing workforce during 60 years operation. To access chemical exposures by specific jobs calendar years, we reviewed complete work histories, examined detailed job descriptions available going back 1940, interviewed longterm employees, conducted walk-through visits...
To assess potential health risks associated with work in a large motion picture film-processing facility.A retrospective cohort mortality study was conducted during 1960-2000 among 2646 film workers. Job family categories, created from detailed employee history information, were used to evaluate chemical exposure patterns.Overall as expected (standardized ratio [SMR] = 1.1; 95% confidence interval [CI] 1.0-1.2). Statistically significant associations found for suicides (SMR 2.0; CI 1.2-3.0)...
