U.S. EPA Proposes Policy on Nanoscale Materials in Pesticide Products

The U.S. Environmental Protection Agency (U.S. EPA) announced recently that U.S. EPA will obtain information on nanoscale materials in pesticide products to help the agency determine whether the registration of a pesticide may cause unreasonable adverse effects on the environment and human health. U.S. EPA plans to publish policy options in the Federal Register shortly. More information about the proposed notice is available at the U.S. EPA Web site.

US adds formaldehyde to list of carcinogens

As reported by Reuters, the U.S. government has added formaldehyde, a substance found in plastics and other commonly used products, to a list of known carcinogens and warned that the chemical styrene might cause cancer. In a report prepared for the Secretary of the Department of Health and Human Services (HHS), scientists warned that people with higher exposure to formaldehyde were more at risk for nasopharyngeal cancer, myeloid leukaemia and other cancers.

EPA Improves Access to Information on Hundreds of Chemicals

The Environmental Protection Agency (EPA) is making it easier to find data about chemicals. EPA is releasing two databases - the Toxicity Forecaster database (ToxCastDB) and a database of chemical exposure studies (ExpoCastDB) - that scientists and the public can use to access chemical toxicity and exposure data. Improved access supports EPA Administrator Lisa P. Jackson's priorities of protecting Americans' health by assuring the safety of chemicals and expanding the conversation on environmentalism.

New Substances Added to HHS Report on Carcinogens

The Department of Health and Human Services (HHS) has added eight substances to its Report on Carcinogens, a science-based document that identifies chemicals and biological agents that may put people at increased risk for cancer. The Report on Carcinogens now includes 240 listings

Durability of carbon nanotubes and their potential to cause inflammation

The University of Edinburgh, the Institute of Occupational Medicine (Edinburgh), and the Commonwealth Scientific & Industrial Research Organisation (Australia) have collaborated to determine the durability of carbon nanotubes in simulated biological fluid and subsequent fibre pathogenicity, compared with well-characterised fibre controls. This collaborative project was financially supported under Safe Work Australia's Nanotechnology Work Health and Safety Program.

Nano alerts (HSE)

This bulletin service aims to provide an overview of publications of studies that have examined the exposure and potential health effects of nanomaterials, particularly in the occupational setting. The bibliographies may not represent the entirety of the literature identified as filter terms particular to HSE were applied. For example the summary of toxicity studies may list only those that are directly relevant to human health.

Fibres céramiques réfractaires. Isolation et protection thermique en milieu industriel. Guide de prévention

Les fibres céramiques réfractaires (FCR) sont employées ou ont été employées notamment pour l'isolation et la protection thermique de fours industriels, de hauts-fourneaux, de moules de fonderie, etc. En milieu industriel, les secteurs de l'acier et des métaux non ferreux, du verre et de la céramique, des tuiles et briques, de la chimie et de la pétrochimie et de l'énergie sont par exemple concernés. Ces fibres classées cancérogènes possibles pour l'homme doivent faire l'objet de règles particulières de prévention. Ce document est destiné à informer et à donner des réponses pratiques de prévention pour la réalisation de travaux d'isolation ou de protection thermique en milieu industriel mettant en oeuvre des fibres céramiques réfractaires (FCR). Il concerne en particulier les opérations de retrait de FCR, de pose ou de maintenance lourde.
