Title A name given to the resource <h2>Results of the chemical analyses produced at the IRSST for 2001-2005</h2> Subject The topic of the resource <span>The air samples of workers exposed to chemical substances collected by CSST inspectors and occupational health professionals are analyzed in the IRSST's laboratories. The interpretation of the results of these analyses determines which substances are present at high concentrations and in which activity sectors. This information has been compiled for members of the review committee of the standards of the Regulation respecting occupational health and safety (ROHS), the CSST, the health network, as well as joint sector-based associations. This study has led to a series of documents being produced that enable interested people to establish regulatory, strategic and operational priorities, while identifying potential research priorities. It is part of a process to monitor and identify substances that should be the subject of research or of measures to control worker exposure. The authors have also produced annual knowledge summaries of the results of the analyses of the chemical substances produced at the IRSST for the years 2001 to 2005 (catalogue numbers B-071 to B-075).</span> Description An account of the resource <a target="_blank" href="http://www.irsst.qc.ca/en/_publicationirsst_100247.html" rel="noreferrer noopener">http://www.irsst.qc.ca/en/_publicationirsst_100247.html</a> Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource <h2>Quantification de la variabilité biologique - Impact de la variation des niveaux ambiants de contaminants</h2> Subject The topic of the resource <span>Biomonitoring indicators serve as a complement to environmental monitoring for documenting, controlling and preventing worker exposure to chemical contaminants, and vary with factors related to the worker and his environment. In a previous study, the authors examined the individual conditions responsible for this variability. In this publication, they document the effect of variation in exposure levels on the measurement of these indicators. The objective: to propose a model for the mathematical calculation of the total variability while taking the different sources into account. As a complement to previous research in this field, this study provides Québec occupational health professionals with essential information on the total variability that can affect biomonitoring data. The results will be used to compare expected variations in environmental surveillance parameters to the variation in biological indicators, according to different exposure scenarios. This information will be added to the IRSST's biomonitoring guide. The institute's various clienteles will thus have a decision tool applicable to biomonitoring strategies. This research will also yield a computer tool that facilitates calculation of the number of samples required.</span> Description An account of the resource <a target="_blank" href="http://www.irsst.qc.ca/en/_publicationirsst_100327.html" rel="noreferrer noopener">http://www.irsst.qc.ca/en/_publicationirsst_100327.html</a> Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource <h2>Analyse de l'expectoration induite dans la silicose et l'amiantose : corrélation avec la fonction pulmonaire</h2> Subject The topic of the resource <span>Asbestosis and silicosis are the most common pneumoconioses in Québec and are often associated with a gradual deterioration in pulmonary function. The authors of this publication studied the possible role of induced expectoration (IE), a non-invasive technique for analyzing bronchial inflammation, in evaluating the severity of pneumoconioses and a decline in pulmonary function. They wanted to verify whether some markers of the inflammatory and fibrosis processes can be measured in IE and whether they are predictors of clinical evolution. - The authors believe that their findings will have to be verified on a larger number of workers, but that induced expectoration could be used to evaluate workers and to follow subjects</span> Description An account of the resource <a target="_blank" href="http://www.irsst.qc.ca/en/_publicationirsst_100184.html" rel="noreferrer noopener">http://www.irsst.qc.ca/en/_publicationirsst_100184.html</a> Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource <h2>Les effets à la santé reliés aux nanoparticules</h2> Subject The topic of the resource <span>Québec is very active in research in the field of nanoparticle development and nanotechnology. More than 35 production companies already exist or are in the start-up phase. It is believed that the number of Québec workers potentially exposed will grow over the next few years. To prevent the development of occupational diseases or the occurrence of accidents, the IRSST began a review of world-wide scientific knowledge to evaluate whether there are known risks associated with this emerging sector. An initial report addressing the health effects (R-451) shows that a limited number of toxicological studies exist, but all of these studies conclude that there are some health risks following exposure to nanoparticles. Although numerous risks are associated with the nature of nanoparticles, it has now been clearly established that toxicity is related to the surface area of these particles and not their mass, and that, for a given substance, the toxicity is much higher when it is of nanometric size than micrometric size. - The second report (R-455) summarizes current knowledge about nanoparticles, their synthesis and applications, health and safety risks, and the challenges in evaluating occupational exposure. Also discussed are nanoparticle-related occupational health and safety control and prevention aspects.</span> Description An account of the resource <a target="_blank" href="http://www.irsst.qc.ca/en/_publicationirsst_100185.html" rel="noreferrer noopener">http://www.irsst.qc.ca/en/_publicationirsst_100185.html</a> Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource <h2>Portrait de l'utilisation des produits à base d'acrylates en milieux de travail québécois</h2> Subject The topic of the resource <span>Widely used in many industrial sectors, acrylates can cause allergic sensitization, rhinoconjunctivitis and occupational asthma. Knowledge about their exact nature and the generation and analysis methods, in the laboratory as well as by direct-reading instruments, would allow safe bronchial provocation tests to be developed in the exposure chambers created by the IRSST. This activity is an initial step, which consists of documenting the acrylates used in Québec and the evaluation methods available. It will allow a strategy to be established for investigating these compounds and their related health problems. Avenues for R&amp;D and new services will result from this work, namely safe methods for diagnosing respiratory diseases attributable to acrylates.</span> Description An account of the resource <a target="_blank" href="http://www.irsst.qc.ca/en/_publicationirsst_100188.html" rel="noreferrer noopener">http://www.irsst.qc.ca/en/_publicationirsst_100188.html</a> Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
