2023Frank Oliver, Melanie N. Stock, Paul Grossl, Grant Cardon · Urban Agriculture & Regional Food Systems · United States (Salt Lake County)
This study conducted an initial screening survey of soil contaminants (lead, arsenic, and benzo(a)pyrene) in community gardens and urban farms in Salt Lake County, Utah, where urban agriculture is expanding. Lead ranged from 14.8 to 516 mg/kg (mean 91.8) and arsenic from 2.83 to 39.3 mg/kg (mean 11.8), with all arsenic values exceeding the US EPA regional screening level of 0.68 mg/kg. The baseline data were used to develop local screening levels and soil management plans for producers.
CommunityHealthCommunity‐Engaged Assessment of Soil Lead Contamination in Atlanta Urban Growing Spaces
2023Samuel J. W. Peters, Sydney M. Warner, Eri Saikawa, P. Barry Ryan, Parinya Panuwet, Dana B. Barr, Priya E. D'Souza, Gil Frank, Rosario Hernandez, Taranji Alvarado, Arthur Hines, Chris Theal · GeoHealth · United States (Atlanta)
Using community-engaged research, researchers and community gardeners co-designed a study measuring soil lead concentrations via XRF and ICP-MS at 19 urban agricultural and residential sites in west Atlanta and three rural Georgia sites. Most sites were below the EPA residential screening levels but above the University of Georgia's low-risk agricultural levels, and some sites containing metal-refining waste or slag reached three times the EPA level. The findings led local and federal agencies to initiate cleanup of the slag residue.
CommunityHealthPolicyChemically Catalyzed Phytoextraction for Sustainable Cleanup of Soil Lead Contamination in a Community Garden in Jersey City, New Jersey
2023Zhiming Zhang, Dibyendu Sarkar, Frances Levy, Rupali Datta · Sustainability · United States (Jersey City)
This field study demonstrated the effectiveness of a chemically catalyzed phytoextraction model, using the biodegradable chelating agent EDDS with vetiver grass, in a lead-contaminated community garden in Jersey City, New Jersey. Despite ongoing lead input from a nearby construction site, soil lead fell from 1144 to 359 mg/kg over three years. EDDS converted non-plant-available lead forms into plant-available forms, and vetiver roots accumulated more lead than in plots without EDDS.
CommunityHealthMycorrhizal fungi and soil factors influence toxic element uptake in urban grown produce
2023Logan Bowdish, Adalie Duran, Justin Richardson, Eric Vukicevich · Urban Agriculture & Regional Food Systems · United States
In an urban community farm, this study evaluated how crop identity, harvested tissue, and soil factors—including arbuscular mycorrhizal (AM) fungi—affect crop uptake of lead and arsenic. Lead uptake increased with lower soil pH and lower soil phosphorus, greater AM fungal colonization was associated with greater lead uptake, while more fungal storage vesicles related to less arsenic uptake into leaves.

2023Myeong Seok Jeong, Mina Lee, Chaw Su Lwin, Kwon-Rae Kim · 한국토양비료학회지 · Korea (Jinju)
This study investigated heavy metal concentrations in soil and crop leaves from 23 urban gardens in Jinju, Korea, to assess suitability for cultivation. While average concentrations of As, Cd, Cr, Cu, Ni, Pb, and Zn generally did not exceed Korean guidelines, the Geoaccumulation Index indicated ongoing contamination by Cd, Cu, Pb, and Zn. A significant amount of Pb was introduced into some soils from the atmosphere, and continuous monitoring for heavy metals in urban garden soils is required for food safety.

CommunityHealthBiodiversityPolicyCSA & Snap: Business Opportunity For Farmers, Improved Nutrition For The Community
2023Diane Smith, Katherine Selting Smith · Advances in biological sciences research/Advances in Biological Sciences Research · United States
This paper describes a SNAP CSA pilot and introduces the Farm to Families (F2F) Toolkit, developed to engage low-income consumers receiving SNAP benefits in Community Supported Agriculture (CSA). USDA rules now permit SNAP benefits for CSA shares, provided the CSA is SNAP-authorized and prepayment is within 14 days of produce receipt. This aims to expand access to fresh produce for SNAP recipients and support farmers.
