Spatiotemporal Trends and Environmental Inequity of Polycyclic Aromatic Hydrocarbon (PAH) Air Pollutants /Jack J. L Cheng. - 1 electronic resource (111 pages)

Hamilton, Ontario, an industrial city in Canada, experiences high pollutant concentrations and poor air quality, leading to adverse health outcomes. This study examined the spatial and temporal dynamics of polycyclic aromatic hydrocarbons (PAHs) in Hamilton and their relation to environmental justice and gentrification using field sampled data from 2009 and 2022-2023, the Ontario Marginalization Index, and the Canadian Census. Evidence suggests that in Hamilton, PAHs are increasing and are more concentrated where marginalized communities live. Land use regression (LUR) prediction surfaces showed that annually, 2022 - 2023 PAH values and cancer risks were higher than those in 2009. Seasonally, winter PAH concentrations exceeded those of summer. While the spatial patterns of LUR predictions were generally consistent, the spatial pattern of summer 2009 concentrations was distinct from other seasons. Correlation analysis indicated worsening environmental justice, with stronger links between PAH concentrations and marginalization in 2022-2023 than in 2009, driven by socioeconomic status more than demographics. PAH levels were significantly higher in gentrified communities compared to non-gentrified communities. These findings enhance understanding of PAH-related environmental justice in Hamilton from the past to the present, highlighting the interplay between pollution, socioeconomic factors, and urban form.
