“…In order to understand the potential health risk of the vegetables grown in the allotment garden, a comparative analysis against values obtained in previous similar studies (Douay et al 2013;Säumel et al 2012;Warming et al 2015) was performed. Accordingly and despite the apparently high content in soils, Cr values were relatively low (with exclusion of radish that most accumulated Cr, with values of 85 mg kg −1 , Fig.…”

Urban horticulture is increasingly popular for social and economic benefits. However, edible urban crops may be contaminated by airborne pollutants, thus leading to serious health risks. Therefore, a better understanding of contamination risks of urban cultivation is needed in order to define safe practices. In particular, whereas it is commonly accepted that the contamination of urban-grown food comes from airborne pollutants, little is known on a possible contamination by soils. Here, we studied trace metal risk in horticultural crops grown in an experimental urban allotment garden in Bologna, Italy. Seven experiments were conducted between June and November 2015 on tomato, sweet basil, onion, lettuce, kale, bulb fennel and radish. Treatments included two growing systems, soil and soilless, and two fertilization managements, mineral and organic. Trace metal concentrations were measured in soils, substrates and edible plant tissues. We identified preferentially translocated metals by partitioning analysis of tomato, sweet basil and kale. Results showed that crops grown in a soilless system have a lower metal content of −70 % for Cr, −61 % for Cu, −45 % for Cd and −81 % for Ni, compared with those grown in soil. This finding demonstrates that the major contamination risk in an urban area is unexpectedly related to soil pollution.

“…Thus, these values can be used for nutrient intake calculation and consumer risk assessment (Izquierdo et al, 2015;Warming et al, 2015). However, information on element content in berries grown for self-consumption is not widely represented in available scientific literature, and is especially poor is information for the Baltic States.…”

“…Regarding food crops, content of mineral compounds can be affected by applied agricultural practice, site specific conditions like soil mineral and water composition, weather conditions during the vegetation period, plant cultivar and species of plant, maturity of crops at harvesting and other site specific factors (Ekholm et al, 2007;Vincevica-Gaile, 2014). In the course of time, society has become accustomed to the fact that the conventional food market consists of various products derived from all over the world, and many consumers in everyday life do not pay great attention to the geographical origin or other specific impacts that can influence the chemical composition and quality of consumable food products (Säumel et al, 2012;Warming et al, 2015).…”

“…Researchers agree that the exposure routes for humans occur through accidental ingestion of the soil and inhaling of contaminated dust (Kessler, 2013), posing risks to farmers, particularly children. There is less consensus about the health effects of the consumption of crops grown in contaminated soil (Warming et al, 2015;Ferri et al, 2015;Augustsson et al, 2015), probably due to the general lack of studies, particularly in LA. The broad range of variables involved -soil constitution, type of pollutant, type of crop -has impaired comparisons between studies.…”

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.
