This guide contains resources that may be useful for writing the Soil Science Project Report. Depending on your hypothesis, you may need to find different types of information. For instance, you may be interested in the health effects Pb, the concentrations of heavy metals in the Chicago area, etc. Good sources for this type of information include journal articles, books, and US government sites.

1. Research articles. Research articles may contain studies of toxicity, environmental or health effects of metals, concentracion of elements in certain soils, etc. Northwestern University Libraries provide access to many scientific journals and databases. See the Finding Articles tab for details specific to this project.
