“…Ezekben átlagosan 336 mg·kg -1 mennyiségűre csökkent az ólom koncentrációja, azonban ez is a duplája volt a komposztban eredetileg mértnek, azaz a szennyezett talajból az ágyá-sok is szennyeződtek. Az ágyások megfelelő használatával azonban a gyerekek napi ólomfelvétele 1,8-3,3 μg·nap -1 mennyiségre csökkent (CLARK et al, 2008). Ezzel össz-hangban MURRAY és munkatársai (2011) szerint a városi talajokba ültetett zöldségek nehézfémtartalma a talajokhoz kevert komposztok minőségétől és mennyiségétől is függ.…”

“…Concern may be warranted, however, since prior studies of Baltimore soils suggest that soil contaminant levels vary widely [24][25][26]-even within the same garden plot [25]-and at some sites lead levels greatly exceed EPA screening levels (Table S1 in File S1). Soil lead levels have also been shown to increase over time due to atmospheric deposition [37]. Informants called for extra precautions where children may be present in gardens, echoing evidence of children's vulnerability to soil contaminants [24,29].…”

Urban Community Gardeners’ Knowledge and Perceptions of Soil Contaminant Risks

Although urban community gardening can offer health, social, environmental, and economic benefits, these benefits must be weighed against the potential health risks stemming from exposure to contaminants such as heavy metals and organic chemicals that may be present in urban soils. Individuals who garden at or eat food grown in contaminated urban garden sites may be at risk of exposure to such contaminants. Gardeners may be unaware of these risks and how to manage them. We used a mixed quantitative/qualitative research approach to characterize urban community gardeners' knowledge and perceptions of risks related to soil contaminant exposure. We conducted surveys with 70 gardeners from 15 community gardens in Baltimore, Maryland, and semi-structured interviews with 18 key informants knowledgeable about community gardening and soil contamination in Baltimore. We identified a range of factors, challenges, and needs related to Baltimore community gardeners' perceptions of risk related to soil contamination, including low levels of concern and inconsistent levels of knowledge about heavy metal and organic chemical contaminants, barriers to investigating a garden site's history and conducting soil tests, limited knowledge of best practices for reducing exposure, and a need for clear and concise information on how best to prevent and manage soil contamination. Key informants discussed various strategies for developing and disseminating educational materials to gardeners. For some challenges, such as barriers to conducting site history and soil tests, some informants recommended city-wide interventions that bypass the need for gardener knowledge altogether.

“…Heavy metals are present in the soil of many urban vegetable gardens in the United States and Europe (Clark et al, 2008;Cheng et al, 2011;Burt et al, 2014;Ferri, et al, 2015), prompting questions about the potential health consequences of UPA in contaminated areas.…”

This special issue of URBE dedicated to Ecological Urbanism focuses on the role architects, landscape designers and urban planners can play in promoting healthier cities in Latin America. In this paper, we survey some of the empirical evidence that links the built environment with particular health outcomes. For many centuries, urban settlements were associated with adverse health outcomes, especially related to untreatable epidemics. As the science of disease transmission developed throughout the nineteenth century, the infrastructure of cities was transformed to promote improved public health. Significant gains were made, but in much of the world -Latin America included -urban health still remains a major challenge, all the more so as drug resistant strains of disease have become more prevalent. We believe Ecological Urbanism offers a promising framework for addressing these challenges. Distinguished by its integrated, multi-disciplinary foundation, Ecological Urbanism directly links both population and habitat health. This creates a natural opportunity for the design professions to play a more consequential role in shaping the health of urban settlements and, by extension, the regions they center.
