Nutritional profile of the Portuguese cabbage (Brassica oleracea L var. costata) and its relationship with the elemental soil analysis
2016Maria Fernanda Pessoa, Paula Scotti‐Campos, Isabel P. Pais, Ana Feteiro, Daniela Sílvia de Oliveira Canuto, Manuela Simes, João Pelica, Inês Maria Mantinhas Pataco, Vânia Ribeiro, Fernando H. Reboredo, José C. Ramalho, Fernando C. Lidon · Emirates Journal of Food and Agriculture · Portugal
The nutritional profile of "Tronchuda" or Portuguese cabbage produced in urban horticultures from 4 regions of mainland Portugal was studied, along with elemental soil analysis of each sampling site. This study revealed significant interactions between essential elements in soil and plant leaves, the edible part of the plant. In general, these leaves contained poor concentrations of Fe and Si, while Mn was absent, regardless of the sampling sites. Conversely, Ca levels were abundant, ranging between 3.3% and 3.9%. Soils from CAP showed a nutrient exhaustion of Fe, Mn, and Mo, although the highest protein and sucrose contents in the leaves were observed in plants growing in those soils. Protein, lipids, and carbohydrates concentrations differed according to sampling site, reflecting different production practices.

2016Hardiyanto Hardiyanto, Constancio C. de Guzman · Indonesian Journal of Agricultural Science · Philippines (Metro Manila)
This study investigated the levels and distribution of lead (Pb) and cadmium (Cd) in white cabbage, soil, and irrigation water from urban agricultural sites in Las Piñas and Parañaque, Metro Manila, Philippines. Field areas were divided into three sections based on distance from the main road (0, 25, and 50 m), and metal contents were measured by Atomic Absorption Spectrophotometry. The average Pb content (1.09 µg g-1 dry weight) in white cabbage was highest immediately beside the main road, with a similar trend in soil. A negative relationship was found between distance from the main road and Pb and Cd contents in white cabbage and soil. While overall concentrations of Pb and Cd in white cabbage, soil, and irrigation water were within acceptable limits, further study on heavy metal contamination in crops, especially those grown along main roads, was suggested.

2016Catharine Ward Thompson, Peter Aspinall, Jenny Roe, Lynette Robertson · · United Kingdom
This cross-sectional survey investigated the relationship between access to green space and health outcomes (stress, general health) among 406 adults in four highly deprived urban communities in Scotland, United Kingdom. Social isolation and place belonging were the strongest predictors of stress in three communities and of poor general health in the fourth. The amount of green space in the neighborhood, particularly access to a garden or allotment, was a significant predictor of stress, while physical activity, frequency of winter green space visits, and views from home predicted general health.
HealthCommunityGrowing Gardens in Shrinking Cities: A Solution to the Soil Lead Problem?
2016Kirsten Schwarz, Bethany B. Cutts, Jonathan London, Mary L. Cadenasso · Sustainability · Global
This paper proposes reframing the issue of soil lead contamination and urban gardening in shrinking cities from a potential conflict to a potential solution. Many shrinking cities face high soil lead burdens from their industrial past and the historic use of lead-based paint and leaded gasoline, which is often seen as a barrier to urban agriculture. The paper argues that urban gardening can be a solution to the soil lead problem through soil management, including soil testing and the addition of amendments, and through social network and community building.
