Available in PDF, EPUB and Kindle. Book excerpt: Urban environments have a history of anthropogenic input of heavy metals to soils. Toledo, Ohio is an urban setting that has been altered through heavy industry and transportation dating back to the 1800s. Heavy metal contamination in soil has been shown to cause serious health effects in humans, such as brain damage, birth defects, cancer, and even death.A total of 137 Toledo soil samples were collected in collaboration with local Toledo schools, the Manos Community Garden, and a previous study completed by Stewart et al (2014). Stewart's study samples and the local Toledo schools' soil samples were collected by K-12 students through a hands-on citizen science project. The samples were analyzed to determine the concentrations of a series of heavy metals, including arsenic, cadmium, chromium, lead, nickel, and zinc. The results revealed multiple samples with elevated levels of all six focus metals greater than the Ohio EPA's soil background levels of the region. Two of these elements, arsenic and lead, had concentrations higher than the USEPA screening level for soils of this region in 73% and 7% of samples, respectively. Locations with elevated heavy metals concentrations in soils were mostly residential yards with older houses and within areas of high transportation. Therefore, the elevated levels of heavy metals were likely deposited from a legacy of human activities. Heavy metal predictive concentration maps of the Toledo, Ohio area were created to show possible areas of concern. The predictive maps showed a higher concentration of most elements in the Old West End area of Toledo. The findings were presented to the collaborating schools and in public forums to educate citizens about elevated heavy metal soil contamination in their area. They were given possible reasons for the contamination, explaining the harmful side effects of human activities on the soils. The health risks associated with the contamination were presented along with how to prevent health issues and how to take precautions around heavy metals.

Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the naturally occurring concentrations of metals in unimpacted wetland soils at the Savannah River Site located near Aiken, SC. Soil samples were collected from three broad categories of wetlands: (1) large stream floodplain wetlands, (2) small stream floodplain wetlands, and (3) upland bays and depressions. Samples were collected from 75 locations to a depth of 3.1 m. All samples were analyzed for selected metals using EPA protocol and standard methods. Additionally, the pH, exchange capacity, and total organic carbon content of each sample was determined. Standard summary statistics were calculated and results are presented for each constituent. Box plots were also created relating metals concentrations to grain size distribution. Metals concentrations were found to increase with increasing silt and clay content. This increase in concentration was attributed to increasing cation exchange capacity and increasing organic matter content.
