Legacy contamination in Chicago urban park soils: Spatial patterns, socioeconomic disparities, and implications for urban agriculture
2026Jenkins E. M., Heafner H., Montgomery J., Soumano V., Paltseva A. A. · iScience · 米国・シカゴ
Portable X-ray fluorescence measurement of seven trace elements in 233 topsoil samples from five Chicago parks. Lead, arsenic, copper, zinc and chromium exceeded Illinois background levels in 89–100% of samples; arsenic exceeded EPA screening levels in 94% of samples and lead in 7%. Contamination was higher at parks farther from the city centre — Douglass and Humboldt parks, in predominantly minority, lower-income neighbourhoods — than at Cottontail, Grant and Webster. Principal-component analysis identified an anthropogenic signature (PC1, 51.7%) driven by Pb, Zn, Cu and As and a geogenic signature (PC2, 17.0%) associated with Mn and Ni. Areas of Douglass and Humboldt parks were classified as not safe for gardening in native soil; Webster as safe with minor restrictions. The authors conclude that park-soil contamination follows socioeconomic gradients, reflecting environmental injustice and a need for targeted remediation.

2023Bethaney Turner · · Global
This chapter explored human-soil relations in urban home and community gardens through ethnographic fieldwork. While biodiverse soil offers direct health benefits, the presence of contaminated, toxic soils, prevalent in lower socio-economic neighborhoods, was shown to expose inequities in access to safe gardening sites and hinder the realization of potential therapeutic benefits. It argues that the therapeutic benefits of gardens are best realized when humans cultivate attentive relationships with myriad multispecies companions.
