Ionising radiation and risk of death from leukaemia and lymphoma in radiation-monitored workers
An international cohort study Background: There is much uncertainty about the risks of leukaemia and lymphoma after repeated or protracted lowdose radiation exposure typical of occupational, environmental, and diagnostic medical settings. We quantified associations between protracted low-dose radiation exposures and leukaemia, lymphoma, and multiple myeloma mortality among radiation-monitored adults employed in France, the UK, and the USA. Methods: We assembled a cohort of 308 297 radiation-monitored workers employed for at least 1 year by the Atomic Energy Commission, AREVA Nuclear Cycle, or the...
Kidney Cancer Risk in Oil Refining in Finland
A Nested Case-Referent Study Objective: The purpose of this study was to assess whether occupational exposure to hydrocarbons in the oil-refining activity increases the risk of kidney cancer. Methods: This case-referent study was nested within the cohort of employees in the oil refinery industry in Finland in 1967 to 1982 (n = 9454). The final data included 30 cases of kidney cancer and 81 age- and sex-matched referents. Results: There was a threefold increase in the kidney cancer risk for exposure to hydrocarbons in crude oil (odds ratio, 3.1; confidence interval, 1.1 to 8.9; 11 exposed cases...
Change in airway inflammatory markers in Danish energy plant workers during a working week
Introduction: It is well known that exposure to organic dust can cause adverse respiratory effect. The pathogen-associated molecular patterns (PAMPS) in the organic dust, such as endotoxin from Gram-negative bacteria cell wall and fungal components, can trigger the release of cytokine (e.g. Interleukin 1 beta (IL-1 beta)) and chemokine (e.g. Interleukin 8 (IL-8)) from the immune cells in the airways. Objective: To evaluate the potential inflammatory effects of organic dust exposure in energy plants in Denmark. Materials and methods: Nasal lavage (NAL) and exhaled breath condensate (EBC) were sampled...
Exposition à des moisissures dans le milieu hospitalier et dans des usines de production de biogaz
Intérêt des protections individuelles et collectives Les champignons filamenteux se développent de manière ubiquitaire sur de nombreux substrats organiques. Les spores se retrouvent dans les poussières et sont souvent inhalables. De plus en plus de données scientifiques pointent l'inhalation de moisissures comme cause d'allergie respiratoire ou cutanée aussi bien dans l'environnement (maisons insalubres) que dans le milieu du travail, notamment dans les industries de compostage de matière organique ou de fabrication de bioéthanol...
Comparison of risks from carbon dioxide and natural gas pipelines
Carbon capture and storage (CCS) is likely to form a significant part of the UK's strategy for achieving its Kyoto targets for CO2 emission reduction. CO2 is not currently regulated as a dangerous fluid under the Pipeline Safety Regulations (PSR) so further investigation is required to determine if it should be re-classified.
