Current Intelligence Bulletin 62 : Asbestos Fibers and Other Elongate Mineral Particles: State of the Science and Roadmap for Research

The National Institute for Occupational Safety and Health (NIOSH) considers asbestos to be a potential occupational carcinogen and recommends that exposures be reduced to the lowest feasible concentration. As the federal agency responsible for conducting research and making recommendations for the prevention of worker injury and illness, NIOSH has undertaken a reappraisal of how to ensure optimal protection of workers from exposure to asbestos fibers and other EMPs. As a first step in this effort, NIOSH convened an internal work group to develop a framework for future scientific research and policy development. The NIOSH Mineral Fibers Work Group prepared a first draft of this State of the Science and Roadmap for Scientific Research (herein referred to as the Roadmap), summarizing NIOSH's understanding of occupational exposure and toxicity issues concerning asbestos fibers and other EMPs.

Nanotechnologies - neurotoxic effects of nanomaterials

There are certain concerns regarding the safety for the environment and human health from the use of engineered nanoparticles (ENPs), which leads to unintended exposures, in contrast to the use of ENPs for medical purposes. Animal experiments have shown that investigated ENPs (metallic nanoparticles, quantum dots, carbon nanotubes) can translocate to the brain from different entry points (skin, blood, respiratory pathways).

NIOSH seeks public input to update its nanotechnology strategic plan

The National Institute of Occupational Safety and Health is seeking public input "on the types of hazard identification and risk management research that should be considered for updating the NIOSH 2009 nanotechnology strategic plan," the agency announced in a March 7 Federal Register notice.

NIOSH first issued a strategic plan in September 2005 to help it identify and prioritize nanotechnology research. It updated the plan in 2009 and now plans to develop strategic research goals and objectives through 2015.

NL-Carcinogenicity – evaluation of dinitrobenzene isomers and 1,2-catechol

At request of the Minister of Social Affairs and Employment, the Health Council of the Netherlands evaluates and judges the carcinogenic properties of substances to which workers are occupationally exposed. The evaluation is performed

by the subcommittee on Classifying Carcinogenic Substances of the Dutch Expert Committee on Occupational Safety of the Health Council, hereafter called the Committee.

The Committee evaluated dinitrobenzene isomers. Dinitrobenzenes are used in the production of dyes, explosives, fibres, and as camphor substitute in cellulose nitrate.

The Committee concludes that the data on dinitrobenzene isomers are insufficient to evaluate the carcinogenic properties, and recommends classifying the compounds in category 3*.

A new video podcast on nanotechnology safety from the ASME Nanotechnology Institute

The American Society of Mechanical Engineers (ASME) have just posted a new video on the safe development of nanotechnology, as part of their series of nano educational podcasts. The video features former Project on Emerging Nanotechnologies (PEN) Chief Science Advisor Andrew Maynard and can be viewed here.

The podcast was shot and edited while Maynard was with PEN, and includes coverage of the PEN Nanotechnology Consumer Products Inventory.

Plan cancer et risque CMR : un 2ème rapport d'étape

Le deuxième rapport sur l'avancement du Plan cancer 2009-2013 a été remis au Président de la République, le 4 février 2011, dans le cadre de la journée mondiale de lutte contre le cancer. Structuré en 17 mesures, le plan comporte un volet spécifique sur l'environnement professionnel. Celui-ci rappelle que la surveillance de la prévention des expositions professionnelles aux CMR doit être renforcée, et que les actions de prévention des expositions professionnelles s’inscrivent dans le cadre du Plan santé travail 2010-2014 et du Plan national santé environnement 2009-2013.

Six substances chimiques dangereuses seront interdites dans l’UE d'ici à 2015

La Commission européenne a décidé jeudi d'interdire "dans les trois à cinq ans à venir" six substances utilisées dans l'industrie en raison de leurs dangers pour la santé.

Les six substances sont le musk xylène, le diaminodiphénylméthane (MDA), l'hexabromocyclododécane (HBCDD), le bis (2-éthylexyl) phtalate (DEHP), le benzyl butyl phtalate (BBP) et le dibutyl phtalate (DBP).

Ces six substances chimiques ont été identifiées comme cancérigènes ou toxiques pour la reproduction, dont les phthalates, qui persistent dans l'environnement et s'accumulent dans les organismes vivants. Ces décisions constituent une première étape dans l'application du volet Autorisation établi par le règlement REACH.

Jobs link to women’s lung cancer risk

 Significantly higher rates of lung cancer deaths – sometimes double what would be expected – occurred in US women who worked in more than 40 occupations between 1984 and 1998. The large scale occupational health surveillance study published in the February edition of the American Journal of Industrial Medicine is the broadest analysis of occupation, industry and lung cancer among US women to date. More than 40 industries were identified as having excessive lung cancer deaths, including manufacturing, transportation, retail trade, agriculture, forestry and fishing and nursing/personal care.
