Lawrence between Cornwall and Blanc-Sablon as well as along the Saguenay, excluding the Great Lakes, the international section of the river and the tributaries of the St. [...] However, due to gaps in our present knowledge, we cannot determine the effects of the contaminated sites on the health of the beluga. [...] Five pathways of exposure were identified for the beluga: 1. Consumption of benthos at contaminated sites; 2. Consumption of fish that feed at the contaminated sites; 3. Skin exposure to substances released from the sites; 4. Consumption of benthos contaminated by substances released from the sites; 5. Consumption of fish contaminated by substances released from the sites. [...] The model developed involves six main variables: 1) areal extent of the site, 2) average concentration of each toxic substance in surface sediments, 3) relative rate of release of toxics to the water column, 4) relative rate of transport of released substances to the beluga's range, 5) relative biomagnification potential of toxics in the beluga's prey, and 6) relative dangerousness of the toxics f [...] In view of the high levels of uncertainty associated with the model variables, a sensitivity analysis was conducted to determine the degree of variability of the ranking based on relative risk.

Book Description
This document reviews the current state of knowledge about St. Lawrence belugas, recommends a series of actions for ensuring their survival and proposes an implementation schedule. The goal of the Recovery Plan is to bring population numbers and conditions to a state where natural event and human activities will not threaten the survival of the St. Lawrence beluga whale population. A subsidiary goal is to improve the status from endangered to vulnerable, as defined by COSEWIC.

Book Description
The St. Lawrence Vision 2000 agreement is a federal/provincial initiative with the goal of restoring, conserving, and protecting the St. Lawrence River and its ecosystem in order to reclaim the river for the public while ensuring its sustainable development. This report briefly describes the results and the progress being made in activities under way to achieve the goals of the components of St. Lawrence Vision 2000: agriculture (reduction of pesticide use, encourage environmental practices), biodiversity (protect species, conserve habitats), community involvement in projects, industrial & urban pollution prevention, sustainable navigation, human health, and institutional communications. Includes an expenditure summary.
