An updated meta-analysis of formaldehyde exposure and upper respiratory tract cancers.
In this study, we summarize 47 epidemiologic studies related to formaldehyde exposure and use meta-analytic techniques to assess findings for cancers of the lung, nose/nasal sinuses, and nasopharynx.… Expand
Review and meta-analysis of studies of acrylonitrile workers.
Twenty-five epidemiologic studies of acrylonitrile workers were reviewed and subjected to meta-analytic techniques in this study to assess the findings for 10 cancer sites. The analyses indicate that… Expand

A study of 200 persons working with benzene showed no differences in commonly measured hematologic outcomes when compared with 268 nonbenzene workers in the same plant. Exposures ranged from 0.01 ppm… Expand
The Mortality Experience of Workers Exposed to 2,3,7,8‐Tetrachlorodibenzo-p-dioxin in a Trichlorophenol Process Accident
Epidemiologic studies on dioxin, specifically 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD), have not consistently found an increased cancer risk. This study examines mortality rates for 754 employees… Expand
