Soil pollution involving the accumulation of excess heavy metals is toxic to humans and other mammalian life.1 The effect on animals can ac-cumulate in the food chains and instigate public health concerns in the future. Normally, the exposure due to food chain transfer is chronic, however, there are rare acute cases where direct ingestion of such pollutants is poisonous.2 Given the importance of the situation, the determination of toxic heavy metals in the environment is essential.
The primary source of soil pollution can be at-tributed to the history of industrial/commercial activi-ties in certain areas.4 We have chosen to analyze the soil at Northwestern University to highlight human factors and contributions to this pollution. Given the history of the Northwestern, there are many areas of the campus that differ in properties such as the age of buildings, the proximity to bodies of water, areas of construction, and high traffic. For use in our study, the campus was divided into areas A, B, C, D, E, & F (Figure 1). Since Northwestern has been regularly undergoing construction in the past century, we pre-dicted that the areas with older buildings would have different metal concentrations when compared with areas with more recent architecture. Due to the use of lead-based paint in old construction, we expect that there should be a higher concentration of metals such as lead found near older buildings such as University Hall or Locy Hall in area E in comparison to area F with…
