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.

PAHs
Author: Peter E. T. DoubenPublisher: John Wiley & Sons
ISBN: 047086429X
Category : Science
Languages : en
Pages : 404
Book Description
Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.
