A indústria do petróleo possui extensa variedade de riscos ocupacionais em virtude da diversidade de atividades necessárias, seja na extração em águas profundas ou em outros locais isolados como em florestas e desertos, seja no processo de refino cada vez mais assemelhado à petroquímica. Para tanto, os trabalhadores desta indústria possui praticamente todos os riscos ocupacionais, ou seja, físico, químico, biológico. A base energética da sociedade atual é o petróleo não havendo fonte de energia alternativa economicamente viável para a sustentação da economia e indústria nos dias atuais, portan

Within the European Union, the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) Regulation 2006, requires the registration of chemicals by manufacturers and suppliers by a number of deadlines from 2008- 2018. Registrants must prepare a dossier of substance information, incorporating a chemical safety report and exposure assessment for the work activities for which the substance is used. Several computer-based screening (Tier 1) tools mentioned in the REACH guidance are used by Registrants to assess exposure: the ECETOC Targeted Risk Assessment (TRA); STOFFENMANAGER®

Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around point-sources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna. This thesis focuses on the effects on pied flycatcher populations of two such point-sources, a lead mine and enrichment plant, and a sulfide ore smelter. Mining activities at the lead mine ceased in 2001 and pied flycatcher populations were assessed before and after th

A recent chemical spill of 4-Methylcyclohexanemethanol (4-MCHM) in West Virginia left 300,000 people without water. Officials claimed that this compound is not lethally toxic, but potentially harmful if swallowed or inhaled, and can cause eye and skin irritation. Sittig's Handbook of Toxic and Hazardous Chemical Carcinogens reports high exposures from skin contact or inhalation may cause damage to the heart, liver, kidneys, and lungs, and may result in death. However, no quantitative data seem to exist and no references can be found on neurotoxicity. We have investigated the neurotoxicity of

Introduction: Asbestos has been employed in a myriad of industrial applications for more than a century. Of the 181 Mt of asbestos produced worldwide, over 31 Mt was consumed in the U.S. The production and consumption of this mineral eventually was found to cause asbestosis, lung cancer and mesothelioma. While the brunt of the human exposure to asbestos occurred in insulation work, many more workers in other jobs were expose to asbestos fibers. Very little is known about the potential exposure to asbestos in research labs. Goal: In order to investigate potential research lab work exposures, we

Le tannage mineral par les sels basiques de chrome a pris de plus en plus d'importance depuis le debut du siecle. Il fournit un cuir aux proprietes remarquables. Dans le cadre d'une politique d'amelioration de competivite economique de la megisserie francaise, les travaux presentes ont permis la mise au point de nouveaux procedes de traitements des cuirs. Le premier theme considere fut l'operation de vieillissement. En effet, l'immobilisation des peaux tannees lors de la phase de vieillissement constitue un handicap economique. Ceci nous a conduit a rechercher les principaux parametres qui y s

<p>Mantle cell lymphoma (MCL) is an aggressive B-cell malignancy with bad prognosis, which predominates in males with advanced age. However, studies of the endocannabinoid system and how it affects tumour behaviour provides the basis for designing innovative therapeutic strategies that could open new opportunities for treatment of patient with MCL. It has earlier been shown that the cannabinoid receptor ligand (R)-(+)-methanandamide (R-MA) induce cell death in MCL by accumulation of ceramide. Ceramide has a pro-apoptotic effect on the cell but could be metabolized by the enzymes glucosylcerami

Le contrôle des rejets industriels évacués vers les eaux réceptrices du fleuve Saint-Laurent nécessite des évaluations de nature chimique et toxicologique. La toxicité des effluents industriels est étudiée, en partie, par un bioessai standard de mortalité de la truite arc-en-ciel (Oncorhynchus mykiss). Un modèle cellulaire qui consiste à utiliser des hépatocytes de truite en culture primaire est proposé comme alternative. Cet essai a l'avantage de réduire considérablement le nombre de poissons requis pour les essais tout en utilisant des critères d'effet qui sont à la base de l'expression de l

De nombreux effluents industriels contiennent des metaux en solution qui presentent une certaine toxicite et qu'il faut eliminer avant rejet. Dans ce travail, nous etudions la possibilite d'eliminer le nickel present dans un effluent par complexation avec un macroligand de qualite industrielle (acide polyacrylique sulfone), puis ultrafiltration. Le concentrat est ensuite electrolyse afin de recuperer le metal sous forme solide. Une premiere partie presente les essais filtration du complexe. Les resultats montrent que l'on peut retenir le nickel a 99% dans certaines conditions. Ont ete etudies
