Objectives: We examined whether certain characteristics of the social and physical environment influence a child's mode of travel between home and school.

Methods: Students aged 11 to 13 years from 21 schools throughout London, Ontario, answered questions from a travel behavior survey. A geographic information system linked survey responses for 614 students who lived within 1 mile of school to data on social and physical characteristics of environments around the home and school.

Trans-Boundary Metals Pollution In The Okanagan Regions Of British Columbia And Washington State: An Assessment Of Metal Toxicity And Speciation In The Columbia River, Ruth M. Sofield, Catherine P. Bollinger

Border Policy Research Institute Publications

An assessment of the tools available to decision makers responsible for managing allowable concentrations of metals in aquatic environments was conducted.

The assessment was framed around four primary goals, which included an evaluation of the validity of hardness corrected values, the Biotic Ligand Model (BLM), the Visual MINTEQ model (VMINTEQ), and a preliminary understanding of what site-specific qualities made one model a better predictor of toxicity than another.
