This study presents the results of an investigation of respiratory symptoms, lung function, chest X-ray examinations, analysis of specific IgE antibodies and skin prick tests to fungi on 130 tobacco-processing workers and 112 control workers. Industrial hygiene survey and environmental mycological studies were also performed. The average dust concentrations ranged from 13.76 to 29.55 mg/m(3) in...

A number of recent epidemiological studies of lung cancer among occupations that expose workers to dusts or toxic aerosols have reported a larger prevalence of lung cancer among non-smoking than among smoking workers. One recent study using Beagle dogs has also reported significantly fewer respiratory tumors among animals exposed to radon, radon daughters, uranium dust and tobacco smoke than am...
OBJECTIVES To evaluate the relation between occupational dust exposure and lung cancer in tin mines. This is an update of a previous study of miners with high exposure to dust at four tin mines in southern China. METHODS A nested case-control study of 130 male lung cancer cases and 627 controls was initiated from a cohort study of 7855 subjects employed at least 1 year between 1972 and 1974 i...
The complex composition of secondhand smoke (SHS) provides a range of constituents that can be measured in environmental samples (air, dust and on surfaces) and therefore used to assess non-smokers' exposure to tobacco smoke. Monitoring SHS exposure (SHSe) in indoor environments provides useful information on the extent and consequences of SHSe, implementing and evaluating tobacco control progr...
To the Editor: We would like to thank Moolgavkar et aP for their provocative and informative article on lung cancer and its relation to radon exposure and cigarette smoke. Their observations supporting a two-mutation model for both tobacco and radon may help to explain some of the confusing observations regarding respirable crystalline silica, . tobacco smoke, and the development of pulmonary n...
Head and neck cancers account for an estimated 549,000 global cancer diagnoses each year. While tobacco use, alcohol consumption, and HPV16 infection are considered to be the major risk factors for this disease, occupational risk factors, including exposure to asbestos, have also been described, although dust exposures other than asbestos have been historically understudied. We have investigate...
