A number of library catalogues are available on the Web. Checking the availability of books and resource materials online can save you a lot of time.
By searching the staff directories of universities’ web sites, you can find experts involved in contaminant research, environmental science, chemistry, ecotoxicology, and human health issues. Call or e-mail them; they may be willing to help or to point you to someone who can.
Most (too many to list) environmental groups have a Web presence. Search for them under their names or acronyms, or consult directories compiled by provincial environmental networks. See Appendix H for the web site addresses of some groups.
