Respiratory Symptoms in Hospital Cleaning Staff Exposed to a Product Containing Hydrogen Peroxide, Peracetic Acid, and Acetic Acid
Cleaning and disinfecting products consisting of a mixture of hydrogen peroxide (HP), peracetic acid (PAA), and acetic acid (AA) are widely used as sporicidal agents in health care, childcare, agricultural, food service, and food production industries. HP and PAA are strong oxidants and their mixture is a recognized asthmagen. However, few exposure assessment studies to date have measured HP, PAA, and AA in a health care setting. In 2015, we performed a health and exposure assessment at a hospital where a new sporicidal product, consisting of HP, PAA, and AA was introduced 16 months prior. We collected...
L’infection à cytomégalovirus: où en est-on ?
Souvent bénigne, l'infection à cytomégalovirus (CMV) peut entraîner des séquelles importantes chez les immunodéprimés et en cas d'infection in utero. En milieu professionnel, les femmes enceintes travaillant en crèche ont un risque accru. Si l'intérêt d'un dépistage systématique fait débat, le strict respect des mesures d'hygiène et l'information des femmes enceintes constituent les seules recommandations qui font consensus.

Hair, Formaldehyde, and Industrial Hygiene
Even if you're not particularly fashion conscious, it's been pretty hard to miss hearing about the Brazilian Blowout smoothing solution over the past year. Imagining a 10% solution of methylene glycol/formaldehyde being applied, dried, and flat-ironed on hair in a salon is enough to make most industrial hygienists cringe. Until recently, comments about the same product from a fashion-conscious, non-industrial hygienist might have been, “I love the product,” or, “It really tames unmanageable hair.” Source : http://blogs.cdc.gov/niosh-science-blog/2012/02/hair-smoothers...
Formaldehyde Exposures during Brazilian Blowout Hair Smoothing Treatment at a Hair Salon
