Abstract:

Le cancer du sein est le cancer le plus fréquent chez la femme et son incidence a doublé ces 30 dernières années. Les facteurs environnementaux à effet perturbateur endocrinien, tels que les dioxines émises par les activités de combustion industrielle, sont suspectés d'augmenter le risque de cancer du sein. L'alimentation et l'inhalation sont les deux voies majeures d'exposition aux dioxines chez l'Homme. Les données épidémiologiques sur le sujet sont non concluantes, et il existe des limites méthodologiques. Ce travail doctoral avait pour objectif d'étudier l'impact de l'exposition aux dioxin

Abstract:

This study reviews available methods of exposure assessment, examines the effects of exposure misclassification on the ability to identify an association, and focuses on recent progress in subjective exposure modelling. Subjective exposure modelling utilises a framework of parameters identified as likely to control personal exposure levels together with detailed guidance and expert judgement in order to estimate exposure concentrations. As part of a case-control study, the Neurotoxicity of Paint Solvents (NPS) study, the process of evaluating subjects' lifetime exposure to solvents was reviewe

Abstract:

Video exposure monitoring (VEM) consists of taking video recording of a worker performing a task at the same time while personal monitoring is performed using a direct-reading instrument. The video and the exposure data are then merged and synchronized and analyzed together. The industrial hygienist conducting the VEM is able to identify any high level of exposure and note the time when the excessive level happened. The corresponding task of the worker is then identified based from the video shot taken at the same time as the exposure data. The objective of this thesis was to study the impleme

Abstract:

INTRODUCTION: Chemical exposures to US pregnant women have been shown to have adverse health impacts on both mother and fetus. A prior paper revealed that US pregnant women in 2003-2004 had widespread exposure to multiple chemicals. The goal of this research is to examine how environmental chemical exposures to US pregnant women have changed from 2003 to 2010 and to look further at the extent of simultaneous exposure to multiple chemicals in US pregnant women using biomonitoring data available through NHANES (the National Health and Nutritional Examination Survey).

Abstract:

Glyphosate is a leaf-absorbed, systemic herbicide against a wide range of problem annual and perennial weeds that is widely used in crop production, general land management and home gardens. Though glyphosate is the most heavily used herbicide in Australia, its use is not monitored (ATSE, 2002). Controlled residue studies show that residues of glyphosate persist in food crops, creating the potential for a large number of people to be exposed (FAO/WHO, 1986; 2006b; U.S. EPA, 1993). Regulatory studies show that glyphosate per se is practically harmless to humans, wildlife and the environment; ho

Abstract:

Indoor microenvironments can have a relevant contribution towards the total exposure to pollutants. The biomarkers of exposure and effect were analysed in general population, to evaluate the impact of VOCs, PAHs and tobacco smoke exposure in everyday life. We designed a model for toxicological studies, as proof of concept for future studies. We analysed airborne personal exposure to air pollutants, the urinary and oxidative stress biomarkers of three exposure level groups in a non-smoking population from Birmingham, UK, a subset with high exposures to tobacco smoke, and a subset of schoolchild

The primary objective of this research was to investigate exposure to formaldehyde. There has been very little research on personal exposure to pollutants in the community and none on personal exposure to formaldehyde. In Australia, there are very little data on indoor formaldehyde concentrations. This is despite the fact that in Europe and in the United States, formaldehyde is one of the most frequently found indoor air contaminants, and is known to cause both acute and chronic health effects. The results of this research generally support the hypothesis that fixed site monitoring in indo

Abstract:

Hypospadias is a congenital malformation that occurs in 0.3-1% of live births, in which the meatus (the urethral opening) is dorsally malpositioned. Uncorrected hypospadias can cause difficulties in urination, abnormal sexual function, and adverse psychological consequences; surgical correction, though generally successful, constitutes an economic burden for families. Several common classes of pesticides have demonstrated potential to disrupt normal endocrine hormones that regulate fetal genitourinary development.

The measurement of UVR can be used to determine the level of hazard posed by a particular source.

Exposure monitoring is widely used method to assess worker exposure to airborne particles.

Polystyrene (PS) acts as a representative of both nano-plastic and NMs. The deposition of gold (Au) NMs is also likely due to their use in medical applications so that both PS and Au have a potential to interac
