Study on reprotoxic chemicals
A range of legislative instruments are in place at EU level to manage and minimise the risks from occupational exposure to carcinogenic, mutagenic and reprotoxic substances. Carcinogenic chemicals can cause or promote cancers. Mutagenic chemicals can cause genetic mutations. Reprotoxic chemicals can damage the reproductive process. This study assesses a number of options for moderning the current EU legislation, in particular regarding reprotoxic chemicals Source: https://ec.europa.eu/social/main.jsp?catId=738&langId=en&pubId=8220&furtherPubs=yes
State-of-the-art report on reproductive toxicants
Summary Workers' reproductive health can be put at risk by hazardous chemicals, such as pesticides and pharmaceuticals, as well as biological, physical, organisational and psychosocial factors. The issue of reproductive OSH risks has largely been focused on women, and mostly pregnant women, but reprotoxic risks can in fact affect both women's and men's reproductive health. Reprotoxicants can also affect foetal and human development and effects include miscarriages, malformations and functional deficits. The summary presents in short the results of a report that examines the current...
Occupational use of high-level disinfectants and fecundity among nurses
Objective: This study aimed to examine the relationship between occupational use of high-level disinfectants (HLD) and fecundity among female nurses. Methods: Women currently employed outside the home and trying to get pregnant (N=1739) in the Nurses' Health Study 3 cohort (2010–2014) were included in this analysis. Occupational exposure to HLD used to disinfect medical instruments and use of protective equipment (PE) was self-reported on the baseline questionnaire. Every six months thereafter women reported the duration of their ongoing pregnancy attempt. Multivariable accelerated failure...

The Effects of Occupational Exposure of Carbon Disulfide on Sexual Hormones and Semen Quality of Male Workers From a Chemical Fiber Factory
Objective: This study is aimed to analyze the relationship between occupational CS2 exposure and reproductive impairments. Methods: Seventy-six CS2-exposed (9.73?±?2.76?mg/m3) male workers and 94 unexposed workers were selected for study. Worker demographics were assessed with a customized questionnaire. Sexual hormones and sperm-related parameters were measured by biochemical or morphological analysis. Results: The CS2-exposed workers had significantly higher serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and lower levels of testosterone (T). Significant...
Perturbateurs endocriniens
Le colloque INRS/AISS 2016 « Perturbateurs endocriniens et agents sensibilisants : quels risques au travail ? quelle prévention ? » s'est tenu début juin à Paris. Les perturbateurs endocriniens, qui ont la capacité d'interférer avec le système hormonal, sont susceptibles de provoquer des effets nocifs tant chez les individus exposés que sur leur descendance. Ils constituent à la fois un sujet de santé publique et une problématique de santé au travail. En milieu professionnel, les salariés peuvent...
Prostate cancer risk among French farmers in the AGRICAN cohort
Objectives: Prostate cancer is one of the most frequent cancers among men worldwide. Its etiology is largely unknown, but an increased risk has been repeatedly observed among farmers. Our aim was to identify occupational risk factors for prostate cancer among farmers in the prospective cohort study AGRICAN. Methods: Data on lifetime agricultural exposures (type of crops, livestock and tasks including pesticide use, re-entry and harvesting) were collected from the enrolment questionnaire. During the period from enrolment (2005–2007) to 31 December 2009, 1672 incident prostate cancers were...

Les expositions aux cancérogènes, mutagènes et reprotoxiques
Un zoom sur huit produits chimiques Les améliorations sont cependant hétérogènes. L'analyse des huit agents CMR qui touchent le plus de salariés montre que l'exposition au formaldéhyde, au plomb, à l'amiante et aux poussières de bois a fortement diminué tandis que celles à d'autres produits comme la silice cristalline ou les phtalates, important reprotoxique, a plutôt augmenté. Les mesures de protections efficaces contre les produits comme les gaz d'échappement diesel ou les huiles minérales...
Reproductive and developmental toxicity of carbon-based nanomaterials
A literature review We summarized the findings of reproductive and developmental toxicity studies on carbon-based nanomaterials (CNMs). Placental transfer of fullerenes in rats and single-walled (SW) and multi-walled (MW) CNTs in mice was shown after intravenous injection. SWCNTs appeared to be embryolethal and teratogenic in mice when given by intravenous injection and induced death and growth retardation in chicken embryos. In mice-administered MWCNTs, fetal malformations after intravenous and intraperitoneal injections and intratracheal instillation, fetal loss after intravenous injection, behavioral...
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...
Reproductive Health Risks Associated With Occupational Exposures to Antineoplastic Drugs in Health Care Settings
A Review of the Evidence Objectives: Antineoplastic drugs are known reproductive and developmental toxicants. Our objective was to review the existing literature of reproductive health risks to workers who handle antineoplastic drugs. Methods: A structured literature review of 18 peer-reviewed, English language publications of occupational exposure and reproductive outcomes was performed. Results: Although effect sizes varied with study size and population, occupational exposure to antineoplastic drugs seems to raise the risk of both congenital malformations and miscarriage. Studies of infertility...
Workplace Exposures and the National Action Plan for Infertility
Infertility is a significant health issue in the U.S. as well as globally. In addition to the large health and fiscal impacts of infertility, the inability to conceive can be devastating to individuals or couples. Research suggest that between 12% and 18% of couples struggle with infertility,[1] which may be caused by a wide variety of factors including genetic abnormalities, aging, acute and chronic diseases, treatments for certain conditions, behavioral factors, and exposure to environmental, occupational, and infectious hazards. However, many questions about infertility remain unanswered. Today...
EU-OSHA stimulates debate on workplace risks to reproductivity
Various reproductive hazards can be found at the workplace, not only from chemicals, but also from physical, biological, ergonomic or other factors. While the issue of reproductive risks has largely been stigmatised on women, and mostly pregnant women, these risk factors can in fact affect both women's and men's reproductive health and some may also have effects on their children, even on the long term. Awareness at the workplace level is low and targeted information limited. A workshop organised by EU OSHA in cooperation with the French Agency for Food, Environmental and Occupational Health...

Le bisphénol A en question
Un récent avis de l'Anses met en garde sur les risques potentiels liés au bisphénol A (BPA) pour les enfants à naître. L'exposition des femmes enceintes pourrait en effet induire des modifications de la structure de la glande mammaire du fœtus susceptibles de favoriser l'apparition de cancers du sein. L'alimentation constitue la principale source d'exposition mais les travaux ont également permis d'identifier des situations d'exposition professionnelle notamment lors de la manipulation des papiers thermiques (tickets de...
Females Welding and the Unborn Child
The number of women in Canada employed as welders and participating in welding apprenticeship programs is growing. However, little is known about the effects of exposure to metals and other welding tasks on women’s fertility and pregnancy. This project examined the feasibility of conducting a cohort study of female welders, and developed tools to assess workplace exposure and reproductive outcomes.

Birth defects linked to solvent exposures
Exposure to organic solvents during pregnancy increases the risk of certain types of birth defects, a new study indicates. Researchers found mothers with greater exposure were 4 to 12 times more likely to have babies with oral clefts than mothers with less exposure. Metabolites of two large classes of organic solvents - glycol ethers and chlorinated solvents - were linked to occupational use of cleaners and cosmetics in jobs such as hairdressers, chemists and nurses. Exposures at work are commonplace as solvents are present in many paints, adhesives, glues, coatings and are used as degreasing and...
Two reproduction toxicity evaluations – Chloramphenicol and indium and its compounds
The Health Council of the Netherlands has reviewed chloramphenicol and indium compounds. Indium is used in bearings for cars and aircrafts, in solders and low-melting alloys, and in nuclear reactor control rods. Indium and its compounds, including indium antimonide (InSb), indium arsenide (InAs), and indium phosphide (InP), find application in semiconductor devices, transistors, and transistor materials. Indium oxide is used for colouring glass. Indium sulphate is used in electroplating, and radioisotopes of indium and indium compounds (including indium trichloride) are employed in the treatment...
