Since the early 1900's, municipalities have tried to make swimming safer by disinfecting water in swimming pools. However, researchers are increasingly linking disinfection byproducts (DBPs) to health effects ranging from asthma to cancer. It is vital to find a balance between the positive benefits of swimming, the positive benefits of disinfection of pool water and the possible negative health effects due to exposure to DBPs. While significant research has addressed the formation, occurrence, exposure, and effects of exposure to DBPs in swimming pools, very little has been done to address the potential for reducing exposure to DBPs through pool design and management strategies. In addition to potential health impacts, the international sporting community has begun to focus more closely on the environmental impact of sports and related facilities. Energy consumption, water consumption and the use (and potential release) of chemicals are a few ways that swimming pools can have an impact on the environment; however, very little research has been done to date to evaluate them. This proposal addresses human health and environmental impacts of indoor swimming pool facilities through risk assessment and life cycle assessment (LCA). Human health impacts will be addressed through modelling DBP occurrence and reduction in indoor swimming pool facilities. Human-health risk management strategies in pool design, operation and maintenance will be proposed and evaluated using an environmental exposure model validated through sampling in the pool environment. The proposed LCA will assess the life cycle environmental implications of public swimming pools. LCA technique will be applied for the new UBC Aquatic Centre facility as a case study to estimate consumption of chemicals, water, and energy through the life cycle for a typical public swimming pool. The resulting understanding of the formation and control of DBPs in indoor facilities coupled with the understanding of the environmental impacts associated with public swimming pools will improve swimming pool design and operation by industrial partners. The LCA will serve as a framework for further assessment of other swimming pool facilities.

自20世纪初以来，市政当局一直试图通过消毒游泳池的水来使游泳更安全。然而，研究人员越来越多地将消毒副产物（DBPs）与从哮喘到癌症的健康影响联系起来。在游泳的积极益处、泳池水消毒的积极益处和暴露于消毒副产物可能对健康产生的负面影响之间找到平衡至关重要。虽然大量的研究已经解决了形成，发生，暴露和暴露于消毒副产物在游泳池中的影响，很少有人做，以解决通过游泳池设计和管理策略减少暴露于消毒副产物的潜力。除了潜在的健康影响外，国际体育界已开始更密切地关注体育和相关设施对环境的影响。能源消耗、水消耗和化学品的使用（以及潜在的释放）是游泳池对环境产生影响的几种方式;然而，迄今为止，很少有研究对它们进行评估。本建议通过风险评估和生命周期评估（LCA）解决室内游泳池设施对人类健康和环境的影响。将通过模拟DBP发生和室内游泳池设施减少对人类健康的影响。将提出游泳池设计、运营和维护中的人类健康风险管理战略，并使用通过游泳池环境取样验证的环境暴露模型进行评价。拟议的生命周期评估会评估公众泳池在使用周期内对环境造成的影响。LCA技术将应用于新的UBC水上运动中心设施作为案例研究，以估计典型公共游泳池在整个生命周期中的化学品，水和能源消耗。了解室内设施中消毒副产物的形成和控制，以及了解与公共游泳池相关的环境影响，将改善游泳池的设计和工业合作伙伴的运营。寿命评估将作为进一步评估其他游泳池设施的框架。
