The risk of gastric cardia cancer was evaluated by occupation and industry using death certificate data for 24 US states. Among white men, occupations with elevated risk included financial managers, janitors and cleaners, production inspectors and truck drivers. Industries with elevated risk included pulp and paper mills, newspaper publishing and printing, industrial and miscellaneous chemicals, water supply and irrigation. A consistent pattern of risk increase by level and probability of exposure was observed only for sulfuric acid mists. A significant increase in risk was observed for subjects exposed to lead, although crosstabulation of gastric cardia cancer risk by probability and level of exposure did not show consistent trends. Asbestos exposure showed an overall 50% increase but no consistent trends among white men. None of the 12 occupational hazards showed an association with risk for black men.

"Background Sawmill workers have an increased risk of developing occupational asthma and other respiratory symptoms. Wood dust and microorganisms have both been suggested to play a role, but few studies have measured microbial exposure levels in sawmills. Methods The preliminary study reported in this paper assessed airborne dust, bacterial endotoxin and (1,3)-glucan levels in 37 samples from two New Zealand sawmills. Results Nearly one-third of the measured dust levels exceeded 1 mg/m3 and only one sample exceeded the legal limit of 5 mg/m3. Endotoxin levels were clearly elevated with 50% of all measured exposures above 50 EU/m3 (range: 7-588 EU/m3). (1,3)-glucan levels were comparable with levels measured in other industries where workers are exposed to organic dust. Workers in the planing department had the highest mean exposures to dust, endotoxin and (1,3)-glucan. Dust levels were only weakly correlated with endotoxin and (1,3)-glucan levels. Conclusions Endotoxin exposures in sawmill workers are at levels sufficient to potentially contribute to the development of respiratory symptoms. Moreover, measurement of dust exposure is a poor proxy for (1,3)-glucan and endotoxin exposure in sawmill workers."

"This Volume 100C covers Arsenic, Metals, Fibres, and Dusts, specifically Arsenic and Arsenic Compounds, Beryllium and Beryllium Compounds, Cadmium and Cadmium Compounds, Chromium (VI) Compounds, Nickel and Nickel Compounds, Asbestos (Chrysotile, Amosite, Crocidolite, Tremolite, Actinolite and Anthophyllite), Erionite, Leather Dust, Silica Dust, Crystalline, in the form of Quartz or Cristobalite, and Wood Dust.
Because the scope of Volume 100 is so broad, its Monographs are focused on key information. Each Monograph presents a description of a carcinogenic agent and how people are exposed, critical overviews of the epidemiological studies and animal cancer bioassays, and a concise review of the agent's toxicokinetics, plausible mechanisms of carcinogenesis, and potentially susceptible populations, and life-stages. Details of the design and results of individual epidemiological studies and animal cancer bioassays are summarized in tables. Short tables that highlight key results are printed in Volume 100, and more extensive tables that include all studies appear on the Monographs programme website (http://monographs.iarc.fr).

It is hoped that this volume, by compiling the knowledge accumulated through several decades of cancer research, will stimulate cancer prevention activities worldwide, and will be a valued resource for future research to identify other agents suspected of causing cancer in humans. "
