This project aims to: (1) Assess the relationship between the quality of sediment and contaminant source by applying multivariate statistical analysis; Evaluate the possible pathways of contaminant source to environmental receptor by existed transmission model to establish the spatial and temporal variations of contaminant in effluent, river water, and sediment; (2) Establish the judgement process of sediment’s environmental impacted assessment and human health risk assessment by collecting the data of sediments, organisms, and aquatic products (fishes, shellfish, and crustaceans); (3) Integrate sediment’s environmental impact assessment, human health risk assessment, and economic assessment to establish the phased assessment guidance of the economic benefits of sediment pollution.污染底泥多變量統計分析風險評估經濟效益Contaminated SedimentMultivariate Statistical AnalysisRisk AssessmentEconomic Benefit
