  • Assigned protection factors of respiratory protective devices used on asbestos removal worksites ET2013-002 | 2013
    Outline of reasons and objectives
    Following the expert appraisal work published in 2009 by the French Agency for Environmental and Occupational Health & Safety (Agence Francaise de Securite Sanitaire de l’Environnement et du Travail) on asbestos…
  • Mapping of sectors and processes generating Polycyclic Aromatic Hydrocarbons (PAHs) ( EL2012-020 | 2012
    Outline of reasons and objectives
    Recent work has highlighted new activities such as carbon densification and repairing facilities covered with pitch-based coatings, and during which occupational exposure to Polycyclic Aromatic Hydrocarbons…
  • Modeling of polycyclic aromatic hydrocarbon formation during hydrocarbon pyrolysis ET2014-004/C2014-106 | 2014
    Low-pressure carburizing is a heat treatment process used to harden surface steel by enriching the metal with carbon atoms coming from pyrolysis of hydrocarbons. Unfortunately, at the same time, other species, considered to be proved to be carcinogenic…
  • Modeling of polycyclic aromatic hydrocarbon (PAH) formation during hydrocarbon pyrolysis ET2014-004/P2015-061 | 2015
    Hydrocarbon pyrolysis in low-pressure gas carburizing conditions drives to gas phase reactions which lead to the production of Polycyclic Aromatic Hydrocarbons (PAHs). These PAHs are afterwards responsible for soot formation. The aim of the…
  • Reduction at source of PAHs during pyrolysis operations ET2014-004 | 2014
    Polycyclic Aromatic Hyrocarbons (PAHs) are chemical compounds that are sometimes highly toxic, or indeed that are considered by some to be proved carcinogens. A variety of sectors of activity cause PAH emissions: incineration, pyrolysis, diesel…
  • Reducing PAHs emissions at the source in a pyrolysis furnace under gas carburizing conditions EL2012-020/P2013-066 | 2013
    The hydrocarbon pyrolysis is widely used in many engineering applications like synthesis of carbon nanotubes in a chemical vapour deposition, pyrocarbon by depositing on carbon fibers and vacuum gas carburizing of steel. However, during these…
  • Heat treatment and PAHs EL2012-020/P2015-066/NT27 | 2015
    Certain heat treatments using gaseous hydrocarbons as carbon sources generate carcinogenic compounds from the polycyclic aromatic hydrocarbon (PAH) family. In order to identify prevention solutions appropriate to the realities out in the…
  • Maintenance of low-pressure carburising furnaces: a source of PAH exposure EL2012-020/P2016-151 | 2017
    Introduction: Low-pressure carburising is a new technology used to harden steel; the process has been shown to be a source of considerable PAH (Polycyclic Aromatic Hydrocarbons) pollution. Some PAH are carcinogenic, and activities such as furnace…
  • Percutaneous absorption of industrial esters: structure-activity relationship between absorption flux and substitution of the aromatic-type acid group EL2015-008 | 2015
    Determining the intensity of the absorption flux of industrial toxic substances is necessary to define the risk related to exposure via the skin. Structure-activity relationships make it possible to estimate the absorption flux of numerous…
  • Artificial sebum as a vehicle for studying ex vivo percutaneous absorption of three solid and lipophilic industrial toxicants B.4/2.165/C2016-008 | 2016
    For testing skin absorption of chemical substances, OECD Test Guideline 428 (OECD, 2004)1 provides some recommendations as to how substances should be prepared:
    “The test substance preparation (e.g., neat, diluted or formulated material containing…
