Filling the gaps in current Life cycle impact assessment framework

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。***首先通过将监测的职业暴露浓度、每个部门的劳动时间和影响因素与潜在的人体健康损害直接联系起来，建立了LCA中职业暴露的表征模型。通过一家家具公司的案例研究对其进行评估，该公司将进行全面的生命周期分析，包括职业接触造成的人类健康负担。该方法最初是为美国环境开发的，然后将转换到加拿大和法国的环境中，目的是分析除了模型不确定性之外的区域变化的重要性。该项目的成果将被转移到工作健康与安全领域，以帮助公司提高其超越监管门槛的排放控制能力，并通过制定职业暴露行业基准来加强其整个价值链的整体风险管理，公司将与这些基准进行比较并提高自己的绩效。***在对已发表的方法进行系统分析和由LCA和水足迹专家组成的国际小组建立科学共识的基础上，首先制定了一个将用水与对生态系统质量的潜在影响联系起来的强有力框架。在这些建议的基础上，建立了一个特征模型，以评估水力发电（即水库的水调节和管理）对生态系统质量的影响，并对水文变量（如水位、流量、达到满池时间）对水生物种种群动态的影响进行量化。这些发展将在IMPACT World+中实施，并用于评估hydro qu<s:1> .*****的千瓦时

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.*****
