Risques pour l’audition d’une exposition combinée bruit et solvants
Résultats d'étude INRS sur le disulfure de carbone et les bruits impulsionnels. Une étude de l'INRS montre que l'exposition au disulfure de carbone, solvant a priori sans effet ototoxique, et aux bruits impulsionnels (non continus) peut entraîner un risque accru de pertes auditives, ce même en dessous de la valeur limite d'exposition au bruit. D'autres effets réversibles peuvent aussi être observés, comme une augmentation de la fatigue auditive en présence de bruit continu. Ces mécanismes non identifiés...
Expositions professionnelles à des agents cancérogènes respiratoires chez les salariés en 2010
Introduction – Les cancers respiratoires sont les plus fréquents des cancers professionnels, mais très peu de données sont disponibles pour quantifier l'exposition professionnelle aux cancérogènes respiratoires. L'objectif de ce travail était d'évaluer en France la proportion de salariés exposés à des agents cancérogènes respiratoires et d'identifier les groupes professionnels les plus exposés, à des fins de prévention. Méthode – À partir des données...
State of the evidence 2017: an update on the connection between breast cancer and the environment
Singly and in combination, these toxicants may have contributed significantly to the increasing rates of breast cancer observed over the past several decades. Exposures early in development from gestation through adolescence and early adulthood are particularly of concern as they re-shape the program of genetic, epigenetic and physiological processes in the developing mammary system, leading to an increased risk for developing breast cancer. In the 8 years since we last published a comprehensive review of the relevant literature, hundreds of new papers have appeared supporting this link, and in...
Cured-in-Place-Pipe (CIPP): Inhalation and Dermal Exposure Risks Associated with Sanitary Sewer, Storm Sewer, and Drinking Water Pipe Repairs
Cured-in-place-pipe (CIPP) is the most popular water pipe repair method used in the U.S. for sanitary sewer, storm sewer, and is increasingly being used for drinking water pipe repairs. Today, approximately 50% of all damaged pipes are being repaired using CIPP technology. The CIPP procedure involves the chemical manufacture of a new plastic pipe called a CIPP inside a damaged water pipe. Little is known about CIPP worker exposures and health risks. CIPP manufacturing sites are highly transient, with a single installation location being used from a few hours to a few days. Unlike traditional manufacturing...
Intervention to diminish dehydration and kidney damage
Objective: The aim of this study was to assess the potential to reduce kidney function damage during the implementation of a water, rest, shade (WRS) and efficiency intervention program among sugarcane workers. Methods: A WRS intervention program adapted from the US Occupational Safety and Health Administration (OSHA) coupled with an efficiency program began two months into the 5-month harvest. One of the two groups of workers studied was provided with portable water reservoirs, mobile shaded tents, and scheduled rest periods. Health data (anthropometric and questionnaires), blood, and urine were...
Case-control study on occupational exposure to extremely low-frequency electromagnetic fields and glioma risk
Background: Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO. Methods: Life time occupations were assessed in case-control studies during 1997-2003 and 2007-2009. An ELF-EMF Job-Exposure Matrix was used for associating occupations with ELF exposure (μT). Cumulative exposure (μT-years), average exposure (μT), and maximum exposed job (μT) were calculated. Results: Cumulative exposure gave for astrocytoma grade IV (glioblastoma multiforme) in the...
Occupational exposure to extremely low-frequency magnetic fields and risk for central nervous system disease
An update of a Danish cohort study among utility workers Purpose: Evidence of whether exposure to extremely low-frequency magnetic fields (ELF-MF) is related to central nervous system diseases is inconsistent. This study updates a previous study of the incidence of such diseases in a large cohort of Danish utility workers by almost doubling the period of follow-up. Methods: We investigated the risks for dementia, motor neurone disease, Parkinson disease, multiple sclerosis and epilepsy among 32,006 men employed at the 99 utility companies that supplied Denmark with electricity during the period...
Fire Simulation and Cardiovascular Health in Firefighters
Background: Rates of myocardial infarction in firefighters are increased during fire suppression duties, and are likely to reflect a combination of factors including extreme physical exertion and heat exposure. We assessed the effects of simulated fire suppression on measures of cardiovascular health in healthy firefighters. Methods: In an open-label randomized crossover study, 19 healthy firefighters (age, 41±7 years; 16 males) performed a standardized training exercise in a fire simulation facility or light duties for 20 minutes. After each exposure, ex vivo thrombus formation, fibrinolysis...
Parkinson’s disease and occupational exposures
A systematic literature review and meta-analyses Objectives: We conducted a systematic literature review to identify studies fulfilling good scientific epidemiological standards for use in meta-analyses of relevant risk factors for Parkinson's disease. Methods: Our search identified 103 original publications on associations between work and Parkinson's disease. GRADE guidelines were used to ensure high scientific quality, and reliable guidelines were applied to classify the papers. Of the 103 articles, 47 fulfilled good scientific standards while 56 were methodologically deficient and thus...
The risk of cataract in relation to metal arc welding
Objectives: There are indications that solar ultraviolet radiation (UVR) increases the risk of cataract, but there is only circumstantial evidence that metal welding, an important occupational source of UVR exposure, is a risk factor. The objective of this study is to unravel if metal welding increases the risk of cataract. Method: We compared the risk of being diagnosed with cataract from 1987–2012 in a historic cohort of 4288 male metal arc welders against a reference group comprised of Danish skilled and unskilled male workers with similar age distribution. For the welders' cohort...
Ototoxic chemicals
Chemicals that result in hearing loss It is well documented that occupational noise exposure is a significant health hazard that leads to permanent noise-induced hearing loss (NIHL) and we have the National Exposure Standard for Occupational Noise to deal with this. It is less well known that a substantial number of medications and common industrial chemicals can also cause hearing loss themselves or exacerbate the effects of noise. These chemicals are said to be ototoxic (oto = ear, toxic = poisonous). They may damage the cochlea in the inner ear and/or the auditory neurological pathways leading...
The Breast Cancer Fund: Working Women and Breast Cancer
The State of the Evidence Based on the current evidence, action to reduce workplace exposures linked to breast cancer is imperative. The Breast Cancer Fund has spent nearly 15 years translating the science that links environmental exposures to breast cancer, and advocating for change. In the past several years, it has become increasingly evident that the workplace may be a substantive source of many of these exposures and of the resulting risk for breast cancer.

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...
Miscarriage Among Flight Attendants
Background: Cosmic radiation and circadian disruption are potential reproductive hazards for flight attendants. Methods: Flight attendants from 3 US airlines in 3 cities were interviewed for pregnancy histories and lifestyle, medical, and occupational covariates. We assessed cosmic radiation and circadian disruption from company records of 2 million individual flights. Using Cox regression models, we compared respondents (1) by levels of flight exposures and (2) to teachers from the same cities, to evaluate whether these exposures were associated with miscarriage. Results: Of 2654 women interviewed...
Occupational Exposure to Ionizing Radiation and Risk of Breast Cancer in Western Australia
Objective: To evaluate current breast cancer risk due to occupational exposure to ionizing radiation. Methods: We analyzed data from the Western Australian population-based Breast Cancer Employment and Environment Study. The Breast Cancer Employment and Environment Study included 1205 cases with incident breast cancer during 2009–2011 and 1789 controls. Age-adjusted odds ratios (ORs) were estimated with logistic regression models. Results: There was a weak, not statistically significant association between breast cancer and occupational exposure to ionizing radiation (OR = 1.16; 95% confidence...

Climate Change and Occupational Health and Safety in a Temperate Climate: Potential Impacts and Research Priorities in Quebec, Canada
The potential impacts of climate change (CC) on Occupational Health and Safety (OHS) have been studied a little in tropical countries, while they received no attention in northern industrialized countries with a temperate climate. This work aimed to establish an overview of the potential links between CC and OHS in those countries and to determine research priorities for Quebec, Canada. A narrative review of the scientific literature (2005–2010) was presented to a working group of international and national experts and stakeholders during a workshop held in 2010. The working group was invited...
Acute Cardiovascular Effects of Firefighting and Active Cooling During Rehabilitation
Objectives : To determine the cardiovascular and hemostatic effects of fire suppression and postexposure active cooling. Methods : Forty-four firefighters were evaluated before and after a 12-minute live-fire drill. Next, 50 firefighters performing the same drill were randomized to undergo postfire forearm immersion in 10[degrees]C water or standard rehabilitation. Results: In the first study, heart rate and core body temperature increased and serum C-reactive protein decreased but there were no significant changes in fibrinogen, sE-selectin, or sL-selectin. The second study demonstrated an increase...
