This proposal is motivated by public concern about the negative impacts of toxic chemicals. The research goal is to provide information and tools to government agencies entrusted with protecting human and ecological health through chemical management policies and regulations, and to provide advice to the public on effective ways to minimize exposure to toxic chemicals. The knowledge needed to achieve this goal includes chemical sources, emissions, transport pathways and exposures. We propose to fill this need by connecting sources and emissions through to human and ecosystem exposures to toxic chemicals or “chemicals of concern”. Those chemicals include brominated and organophosphate flame retardants, phthalate plasticizers, synthetic musk fragrances, selected current use pesticides, and other semi-volatile organic compounds (SVOCs) prioritized by Canada’s Chemical Management Plan. The SVOCs of interest here are released from products and materials. Their concentrations are highest indoors where Canadians spend 90% of their time and hence have opportunities for exposure. The SVOCs are then released from indoors to outdoors, where outdoor urban environments and ecosystems have high concentrations due to the confluence of people and activities.

这一提议是出于公众对有毒化学品负面影响的关注。研究目标是向负责通过化学品管理政策和法规保护人类和生态健康的政府机构提供信息和工具，并向公众提供关于尽量减少接触有毒化学品的有效方法的建议。实现这一目标所需的知识包括化学品来源、排放、运输途径和接触。我们建议通过将来源和排放与人类和生态系统接触有毒化学品或“令人关切的化学品”联系起来来满足这一需求。这些化学品包括溴化和有机磷酸盐阻燃剂、邻苯二甲酸酯增塑剂、合成麝香香料、目前使用的某些农药以及加拿大化学品管理计划优先考虑的其他半挥发性有机化合物。这里感兴趣的SVOC是从产品和材料中释放出来的。这些物质在室内的浓度最高，加拿大人90%的时间都在室内度过，因此有机会接触这些物质。SVOC随后从室内释放到室外，由于人和活动的汇合，室外城市环境和生态系统具有高浓度。
