Parkinson's disease is thought to be the second most common neurological disease (after Alzheimer's), affecting an estimated 34,000 to 60,000 Canadians and 4,500 to 8,000 British Columbians. Previous studies have examined associations between Parkinson's disease and genetic factors, environmental exposures (e.g. pesticides, heavy metals, solvents), and major head trauma. In an earlier study, the research team explored the distribution of Parkinson's disease within occupational groups. That work lead to the development of ideas about potential relationships between the disease and...
Les écrans à tubes cathodiques sont des déchets dangereux du fait de la présence de plomb, de poudres luminescentes, de baryum, de cadmium et de verres spécifiques. Ces équipements présentent donc un risque chimique particulier pour l'homme et l'environnement. Ce document traite uniquement du risque chimique, l'un des principaux risques dans cette filière. Il s'adresse aux entreprises concernées par les opérations de traitement des écrans à tubes cathodiques (démanteleurs d'écrans...
Inmates and employees at 10 federal prisons were exposed to toxic metals and other hazardous substances while processing electronic waste for recycling, a four-year investigation by the Justice Department's inspector general found. A report issued last week by the Office of the Inspector General said unspecified amounts of that waste were shipped overseas, possibly to undeveloped countries. Reports have multiplied in recent years that electronic waste is being dumped in developing nations, where it can harm local populations by leaching into groundwater or attracting scavengers who are exposed...
Concerns about the health effects of occupational exposure to fertilizers have been raised by both tree planters and contractors. Fertilizers, which sometimes contain heavy metal contaminants, are often applied at the same time that tree seedlings are planted. Some seedlings are also treated with chemical insecticides and fungicides in the nurseries, and it is possible that there could be pesticide residues on the seedlings when they are being planted. The purpose of this study was to examine these potential exposures and to investigate potentially related health effects. http://www.worksafebc...
At the request of the Minister of Social Affairs and Employment, the Health Council of the Netherlands evaluates the effects on the reproduction of substances at the workplace. http://osha.europa.eu/en/news/NL_Aluminium_reprotoxic_potential
Le béryllium est un métal peu connu de ceux qui l'utilisent car il est le plus souvent « caché » dans des alliages ou des céramiques. Mais il est bien connu des spécialistes pour sa dangerosité : il est irritant, allergisant, toxique et cancérogène. On estime qu'environ 12 000 salariés en France y sont exposés. Ce chiffre pourrait aller en augmentant avec le développement du recyclage des métaux. Une démarche de prévention appropriée peut protéger les travailleurs...
To achieve harder metals that don't wear down quickly, manufacturers are considering the use of tungsten-carbide nanoparticles and cobalt, which is thought to increase the strength and durability of the finished product. Unfortunately, as Susanne Bastian et al's article "Toxicity of Tungsten Carbide and Cobalt-Doped Carbide Nanoparticles in Mammalian Cells in Vitro" (Supplemental Material available here), demonstrates, increased exposure to these nanoparticles will, in all likelihood, lead to increased incidences of asthma, other respritory illnesses, and lung cancer among workers...
The National Institute for Occupational Safety and Health (NIOSH) requests help in preventing injury and illness in workers at indoor firing ranges in the United States. Workers are potentially exposed to hazardous amounts of lead and noise at these ranges. They include thousands of employees at the firing ranges as well as more than a million Federal, State, and local law officers who train regularly at these facilities. In addition to workers, 20 million active target shooters are potentially exposed to lead and noise hazards at indoor firing ranges. http://www.cdc.gov/niosh/docs/2009-136/
Overexposure to inorganic lead continues to be an important health problem worldwide. Furthermore, recent research has caused increased concerns about the toxicity of lead at low doses. Lead can cause acute and chronic adverse effects in multiple organ systems, ranging from subclinical changes in function to symptomatic, life-threatening intoxication. Since 1992, CDC's state-based Adult Blood Lead Epidemiology and Surveillance (ABLES) program has tracked laboratory-reported elevated blood lead levels (BLLs) in U.S. adults. The vast majority (95%) of reported elevated BLLs have been work related...
This event will provide practical advice and guidance on implementing Human Factors within effective management procedures, and give you the opportunity to have open discussion with the HSE on any issues. The event will outline standards that HSE inspectors will be looking for when inspecting Human Factors topics on COMAH and other chemical sites. http://news.hse.gov.uk/2009/03/18/blood-lead-exposure-%E2%80%93-latest-figures-for-200708/
HSE inspectors have noted that, although Local Exhaust Ventilation (LEV) was often available for controlling exposure to welding fume, it frequently remained unused, due, partly to claims by welders that the LEV was responsible for removing shielding gas and thereby compromising the quality of the weld. However, there appeared to be few data to substantiate the welders’ claims. HSE commissioned this research project to establish whether efficient welding fume capture could be achieved using LEV whilst, at the same time, maintaining weld metal integrity. http://www.hse.gov.uk/research/rrpdf...
A la veille de la réunion de Nairobi (16 février) du Programme des Nations-Unies pour l’Environnement sur les dangers du mercure, France Nature Environnement publie les résultats français de la campagne internationale Zero Mercury. Cette campagne est coordonnée en Europe par le Bureau Européen de l’Environnement (BEE) et au niveau mondial par le Zero Mercury Working Group, un réseau constitué par 75 ONG à travers le monde. Interdit en France en 1998 pour les thermomètres médicaux, le mercure est toujours utilisé...
The aim of this study is to provide a statistical analysis of an exposure dataset provided by Castings Technology International (CTI). The purpose of the analysis is to provide a ‘snapshot’ of current exposure levels to ferrous foundry particulate (FFP) and other chemicals across a range of casting and fabrication related jobs. http://www.hse.gov.uk/research/rrpdf/rr677.pdf
"Interactive Guide to Working Safely with Beryllium and Beryllium-containing Materials," a guide that won a 2008 National Occupational Research Agenda Partnering Award for Worker Health and Safety, is now available on the Brush Wellman Inc. Web site. Brush Wellman, the world's largest producer of beryllium and beryllium-containing materials, developed the guide in January 2008 with Axcept Media, LLC, but until now it was available only in disk form. http://ohsonline.com/articles/2009/02/16/online-guide-explains-safe-uses-of-beryllium.aspx
