Academic Search Complete is a multidisciplinary database with full text articles. It's a good source for articles about research studies similar to the ones you're conducting in the Environmental Science Lab. You will want to find primary literature, which means articles that describe one study that was done by the authors. Here are the steps to find the articles:
1. Use the link above to go to Academic Search Complete. If you're off campus, you'll be asked to enter your EUID and password.
2. Do a Basic Search with any of the following search statements: [trinity river and texas], [trinity river and watershed], [trinity river and soil], [trinity river and water quality], [watershed and toxicology and united states].
3. If you get more than 25 results, narrow down your search. Refine your results to Scholarly Journals only and the last 10 years, then Update the results.
4. Now browse through the articles. Click on a title to read the abstract (summary) of the article and see if it's similar to your study.
5. To get the full text article, select the PDF Full Text or the green Find It button under the article's entry on the results page.
