Graduate Chair Soil Science
Soil Science BiographyI explore how humans poison soil and how soil poisons humans. In Canada, soil cleanup guidelines protect the most sensitive organism at a site for a specific contaminant. For example, typically humans are very sensitive to polycyclic aromatic hydrocarbons (PAH) pollution, whereas soil nutrient cycling is sensitive for Total Petroleum Hydrocarbons (TPH) [REFs 96,92,76]. Thus, at a site contaminated with PAHs and TPH, the site would have to be cleaned up to protect humans and nutrient cycling if both receptors are present. As a result, improving policy and technologies in Canada requires that we investigate how humans and all other ecosystem components interact with, and are affected by polluted soils. Incidental ingestion of soil by humans is the primary exposure pathway by which polluted soils poison humans. And among soil biogeochemical cycles, the nitrogen cycle is proving to be the most sensitive to pollutants. Thus, I focus on incidental soil ingestion and the soil nitrogen cycle to understand how human activities impact ecosystems and how these ecosystems impact human health. | ![]() |
