“…Princewill-Ogbonna and Ogbonna (2011) also reported that fast urbanization in developed cities is responsible for drastic increase of metal concentration in surrounding areas and plant species growing on those sites. They reported that higher liberation of vehicular pollutants in Aba city of Nigeria exhibited variable accumulation of heavy metals in different medicinal plants as demonstrated by AAS mediated chemical profiling.…”

“…The rise in Cr concentration in Bahadurgarh region (heavy industrial area located at the edge of national capital New Delhi) in the present study can be attributed to fast industrialization, higher vehicle density and rapid urbanization.

The increasing prevalence of environmental pollution, especially soil contamination with heavy metals has led to their uptake in the human food chains through plant parts. Accumulation and magnification of heavy metals in human tissues through consumption of herbal remedies can cause hazardous impacts on health. Therefore, chemical profiling of nine heavy metals (Mn, Cr, Pb, Fe, Cd, Co, Zn, Ni and Hg) was undertaken in stem and leaf samples of ten medicinal plants (Acacia nilotica, Bacopa monnieri, Commiphora wightii, Ficus religiosa, Glycyrrhiza glabra, Hemidesmus indicus, Salvadora oleoides, Terminalia bellirica, Terminalia chebula and Withania somnifera) collected from environmentally diverse regions of Haryana and Rajasthan states in North-Western India. Concentration of all heavy metals, except Cr, was within permissible limits in the tested stem and leaf samples. Leaf samples had consistently more Cr compared to respective stem samples with highest concentration in leaf samples of Bacopa monnieri (13.19 ± 0.0480 ppm) and stem samples of Withania somnifera (4.93 ± 0.0185 ppm) both collected from Bahadurgarh (heavy industrial area), Haryana. This amount was beyond the permissible limit of 2.0 ppm defined by WHO for raw herbal material. Other two most perilous metals Pb (2.64 ± 0.0260) and Cd (0.04 ± 0.0274) were also recorded in Bahadurgarh region, although below permissible limits. Concentration of Hg remained below detectable levels in all the leaf and stem samples tested. These results suggested that cultivation of medicinal plants and other dietary herbs should be curtailed near environmentally polluted especially industrial areas for avoidance of health hazards.

Different parts of Ruta chalepensis L. medicinal plant and soil samples collected from three zones in Jordan (Irbid, Al-Mafraq and Ma'an) were analyzed for determination of Pb, Cu, Zn, Cd, Ni and Fe by atomic absorption spectrometry. Heavy metal levels in washed and unwashed parts of R. chalepensis were evaluated and compared statistically. Results show that there was a variation in heavy metal concentrations related to washed and unwashed parts of R. chalepensis in the three zones. Moreover, Pb, Zn, Cu, Cd, and Ni were concentrated in the following order:Two standard reference materials of plant (SRM 1790a; spinach, CRM 281; rye grass) and a standard reference material of soil (GBW 07406) were examined to validate the method used.Results indicate that high recoveries were obtained. Significant variation existed in metal content in different parts of Ruta chalepensis L. for the various locations (P ≤ 0.05).

“…Forest products, including medicinal roots and leaves, as a result, may be more prone to contamination if not sufficiently cleaned. In Aba city, Nigeria, Princewill‐Ogbonna and Ogbonna's (2011) analysis of heavy metal concentrations in urban soil and medicinal plant samples also indicates that accumulation of Zn and Pb from vehicle emissions could be a serious impediment to the quality and safety of specialty forest products intended for human consumption. Based on vegetable crop research, best practices for reducing trace metal contamination to safe levels for consumption in urban soils include the use of woody vegetation buffers and cultivation at greater distance (>10 m) from high‐traffic roads (Antisari et al., 2015; Saumel et al., 2012).…”

“…Where UFG objectives favor structural and biological diversity, as is expected with inclusion of NTFP management, ecosystem services including habitat connectivity and native plant conservation are likewise enhanced (Doody et al., 2010; Lin et al., 2015). However, a potentially toxic load of pesticides and fertilizers in stormwater runoff, lead contamination of soil, and other anthropogenic disturbances pose a barrier to safe cultivation and consumption of these additional crops (Princewill‐Ogbonna & Ogbonna, 2011; Wortman & Lovell, 2013). Nontimber forest product species that may be found less likely to accumulate dangerous concentrations of pollutants, and that are safe for consumption with minimal processing, are more apt for immediate UFG applications.…”

Exploring ‘beyond‐food’ opportunities for biocultural conservation in urban forest gardens

Urban agroforestry efforts have focused primarily on food production, but these dynamic, multiple-strata systems can host a much broader set of functions. This exploratory synthesis describes opportunities and considerations for urban forest gardens' (UFG) capacity to include diverse, biologically important, and culturally relevant nontimber forest species that have medicinal properties, provide decorative and landscaping products, supply raw material for crafts, and other valuable outputs. Literature relevant to social and ecological aspects of design for 'beyond-food' specialty forest crops in urban forest gardens reveals a need for collaborative, participatory, and culturally relevant UFG decision making that addresses access inequities, potential contamination from urban pollutants, and a continued need for education and awareness of UFG multifunctionality. These production spaces can serve as both a biological and cultural repository for species that may be otherwise overlooked in a narrowly oriented food garden, though case study examples indicating contextual elements of implementation are needed to understand specific cultural and health sovereignty benefits. Currently, traditional tropical homegardens serve as a model for biocultural diversity in small-scale urban green spaces. Incorporating conservation goals into urban agroforestry initiatives at varying scales holds potential for growing interest in and commitment to building capacity for this emergent land use.Abbreviations: CIS, critical interpretive synthesis; NTFP, nontimber forest product; UFG, urban forest gardenThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
