Background: Evidence is limited that long-term human exposure to organophosphate (OP) pesticides, without poisoning, is associated with adverse peripheral nervous system (PNS) function. Objective: To investigate associations between OP pesticide use and PNS function, we administered PNS tests to 701 male pesticide applicators in the Agricultural Health Study (AHS). Methods: Participants completed a neurological physical examination (NPx), electrophysiological tests, and tests of hand strength, sway speed and vibrotactile threshold. Self-reported information on lifetime use of 16 OP pesticides was...
Objectives Nickel compounds, inclusive of water-soluble salts, have been classified as human carcinogens by the International Agency for Research on Cancer (IARC). Nickel producers have disputed the classification of soluble nickel compounds for three decades with reference to an alleged absence of excess respiratory cancer among Canadian nickel-exposed electrolysis workers. We evaluated historical data from two electrolytic refineries in Ontario, both included in prominent Canadian reports on occupational nickel-related cancer. Methods For Port Colborne nickel refinery (PCNR) and Copper Cliff...
The European Chemicals Agency has submitted to the European Commission a recommendation that thirteen Substances of Very High Concern should in future not be used without authorisation. These substances are all classified because of their carcinogenic, mutagenic or toxic to reproduction (or a combination thereof) properties. They are used in applications where there is potential for worker exposure. The protection of human health and the environment is at the heart of REACH. Making these thirteen Substances of Very High Concern (SVHCs) subject to authorisation seeks to ensure that their risks are...
Objectives We investigated the association between occupational exposure to endocrine-disrupting chemicals (EDC) and the risk of uveal melanoma using international data of a case–control study from nine European countries. Methods After exclusion of proxy interviews, 280 cases and 3084 control subjects were included in the final analysis. Information on possible exposure to EDC was derived from 27 job-specific questionnaires (JSQ), which solicited detailed questions on occupational tasks. Relative risk estimates were based on the JSQ and potential exposure to a group of endocrine-disrupting...
Objectives This paper aims to investigate the relation between occupational exposure to particles, particle size, and the incidence of ischemic and hemorrhagic stroke. Methods The cohort included all manual workers identified from the Swedish National Census in 1980, who were alive as of 1 January 1987. First time events of ischemic or hemorrhagic stroke during the period 1987–2005 were identified through linkage to the Hospital Discharge Register and the National Cause of Death Register. A job-exposure matrix for exposure to small (1 µm) particles was developed and applied. Hazard...
Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls...
« Tout nouveau cas de mésothéliome, quel que soit son site anatomique (plèvre, péritoine, péricarde…), doit désormais être notifié au médecin de l'Agence Régionale de Santé (ARS), par tout médecin (pathologiste ou clinicien) exerçant en France métropolitaine ou ultramarine et qui en pose le diagnostic ». Tel est le contenu du décret nº 2012-47 du 16 janvier 2012 qui ajoute les mésothéliomes à la liste officielle des maladies à déclaration...
HHE Program investigators assessed salon employees' exposure to formaldehyde when performing hair smoothing treatments using Brazilian Blowout® hair products. Investigators found that during hair smoothing treatments employees' exposures to formaldehyde in air exceeded the ceiling limits set by NIOSH and the American Conference of Governmental Industrial Hygienists. Investigators determined that the Brazilian Blowout Acai Professional Smoothing Solution, Formaldehyde Free Smoothing Formula, contained 11% formaldehyde. Investigators recommended that managers stop using the product. Source...
HHE Program investigators evaluated concerns about lead exposures and indoor environmental quality problems at an indoor firing range. Investigators found that airflow along and downrange of the firing line did not meet NIOSH recommendations. Investigators found that exposure for one instructor, one shooter, and the hazardous materials technician were above the occupational exposure limits for lead for an 8-hour time-weighted average. Surface wipe and floor vacuum samples detected lead in various places. Investigators recommended installing a ventilation system that can deliver the NIOSH-recommended...
ECHA - the European Chemicals Agency has reflected on how they work and what they can do better. The new website is an example of that. It is much easier to use, simpler to search and more intuitive to navigate around. The website is also written in plainer English and is more informative, particularly for non-scientists. Also, most of the material is available in 22 languages. Source : www.echa.europa.eu
Une étude multicentrique descriptive sur la contamination des surfaces par le cyclophosphamide, par l’ifosfamide et par le méthotrexate, a été réalisée dans les centres hospitaliers du Québec en 2008-2010.

The Nanoparticles from Printer Emissions in Workplace Environments report examined particle emissions from laser printers in office environments. A total of 107 laser printers were examined in offices across Queensland. This research was undertaken by Queensland University of Technology and Workplace Health and Safety Queensland. Precautionary advice from the report on how workplaces can assess and control laser printer particle emissions is summarised on the Information sheet Assessing and controlling laser printer particle emissions in workplace environments. To understand the potential health...
Ce guide du ministère de la Santé et des Services sociaux se veut avant tout un outil de référence et de gestion afin de permettre aux gestionnaires des immeubles, au personnel d'entretien des bâtiments et des équipements, ainsi qu'aux intervenants en santé et sécurité du travail, une prise en charge efficace et efficiente de la qualité de l'air intérieur à toutes les étapes du cycle de vie d'un bâtiment et de ses systèmes. Il comporte de précieux renseignements sur : la...
The British Occupational Hygiene Society (BOHS) released in October 2011, Testing Compliance with Occupational Exposure Limits for Airborne Substances . BOHS notes that, when repeat measurements are made of exposures to airborne substances in the workplace, it often happens that a few results scatter on the high side, sometimes four or five times the median or even higher, for no clear reason. This is not due to a failure of control, but happens because there is a statistical chance that the many factors which determine exposure sometimes combine in a way which produces an outlying result. It is...
Une étude publiée dans la revue Annals of Neurology montre un lien possible entre l'exposition à certains solvants (trichloréthylène et perchloroéthylène) et la survenue de la maladie de Parkinson. Selon les chercheurs, l'exposition professionnelle augmenterait significativement le risque de développer la maladie. Les solvants sont utilisés dans de nombreux secteurs industriels. On sait depuis longtemps que ces produits chimiques peuvent avoir des effets néfastes sur la santé des salariés exposés...
