The research program of my second discovery grant aims at addressing current methodological shortcomings and identified research gaps on human toxicity and water use in Life cycle impact assessment (LCIA) by (A) developing an operational model to assess occupational exposure in LCA and (B) developing a robust modeling framework and operational method linking freshwater use to potential impacts on the Ecosystem quality impact indicators. It builds on the knowledge developed from my previous Discovery grant research program and other research activities supported by complementary founding. A characterization model accounting for occupational exposure in LCA is first developed by directly linking monitored occupational exposure concentrations, labor hours in each sector and effect factors to potential human health damages. It is evaluated through a case study form a furniture company, where a full LCA will be performed including human health burdens from occupational exposur. The methodology, originally developed for the US context, will then transposed into to Canadian and French contexts with the aim to analyze the importance of regional variability in addition to model uncertainty. The outcomes of this project will be transposed to the work health & safety domain to assist companies to improve their emission control capacities beyond regulatory threshold and increase their overall risk management across their value chain by developing occupational exposure sectorial benchmarks to which companies would compare and improve their own performances. A robust framework linking water use to potential impacts on ecosystem quality is first developed building on a systematic analysis of published methods and scientific consensus building from an international group of LCA and water footprint experts. Building on these recommendations a characterization model to asses ecosystem quality impacts from hydroelectricity production (i.e. from water regulation and management in reservoirs) is then developed quantifying the effects of hydrological variables (e.g., water levels, discharge, time to reach full pool) on aquatic species population dynamics. These developments will be implemented in IMPACT World+ and used to evaluate the kilowatt-hour of HydroQuébec.

我的第二个发现资助的研究项目旨在通过(A)开发一个操作模型来评估生命周期影响评估（LCIA）中的职业暴露，(B)开发一个强大的建模框架和操作方法，将淡水使用与对生态系统质量影响指标的潜在影响联系起来，解决当前方法上的缺点，并确定在生命周期影响评估（LCIA）中人类毒性和水使用方面的研究差距。它建立在我以前的发现基金研究项目和其他由补充基金支持的研究活动所积累的知识基础上。
