Under the "Bitumen and paving" project which involved the INRS and professionals producers and users, the development of a method for sampling and analysing bitumen fumes was undertaken. This Communication aims to present the developments made…

Exposure to organic vapors in the workplace is a source of occupational risk. Admissible exposure levels are tightly regulated and must be closely monitored. However, the complexity and slowness of the existing complete protocols to determine…

The objective of this study is to develop a technique for analysing atmospheric samples of volatile organic compounds that does not use solvent. This technique is based on coupling extraction using carbon dioxide (CO2) in a supercritical state…

The NIOSH 5042 method for the exposure assessment to the bitumen fumes during road paving or roofing operation has to be improved in order to take into account the vapour phase and to substitute benzene that is used as extraction solvant. A laboratory…

We propose a innovative method for air sampling analysis. Samples are extracted with supercritical CO2 prior to analysis with conventional gas or liquid chromatography. Results presented in this communication concern the first step of the…

Benzene is frequently used to extract collected bitumen fumes from personal sampler substrates. However, this solvent is particularly dangerous because of its carcinogenicity (group 1 of IARC classification). Therefore, to prevent the exposure…

In this study, we propose to develop an analytical device able to desorb any organic compound from any sorbent without using solvents and perform online analysis with gas, liquid and supercritical chromatography. In the first step of this study…
