Assessing potential risk of heavy metal exposure from consumption of home-produced vegetables by urban populations
2004Hough R., Breward N., Young S., Crout N., Tye A., Moir A., Thornton I. · Environmental Health Perspectives · United Kingdom
The study modeled uptake of cadmium, copper, nickel, lead, and zinc into home-produced vegetables and assessed the heavy-metal exposure risk to urban populations from eating homegrown food.
HealthTHE LEGACY OF ALLOTMENT GARDENS IN INDUSTRIAL URBAN SETTINGS
2004Tanja Pless‐Mulloli, Vivienne S. Air, Catherine Vizard, Ian Singleton, D. L. Rimmer, Philip Hartley · Epidemiology · United Kingdom
A study in an urban, industrial allotment site in the UK's northeast assessed the potential for public health impact related to soil contamination by taking 86 soil samples and analyzing vegetables and eggs. All 18 initial soil samples exceeded UK guidelines for lead (median 869 mg/kg) and arsenic (median 40 mg/kg), and widespread contamination with PCDD/F was also found. Despite high soil contamination, the uptake of lead and arsenic into vegetables and eggs was low, and these were not deemed major exposure pathways.

2003Tanja Pless‐Mulloli, Karen L. Foster, J Bush · Epidemiology · United Kingdom (Newcastle upon Tyne)
Investigations in Newcastle upon Tyne, UK, analyzed the extent and consequences of disposing 2000 tons of incinerator ash on over forty allotments. Soil, egg, and vegetable samples (75 soil, 21 egg, 65 vegetable) revealed contamination of footpaths with dioxin/furan (max 9000 ng/kg I-TEQ) and high levels of copper, lead, and zinc. Mean dioxin/furan levels in soil were 38 ng/kg I-TEQ and in eggs were 16.4 ng/kg I-TEQ, indicating significant contamination and potential exposure pathways for allotment gardeners and children.
Contamination & food safetyHealthCommunityPolicyUrban horticulture on the verge of a new century Insights of the International Symposium on Plant Health in Urban Horticulture held in Braunschweig, Germany, from May 22 to May 25, 2000
2001G. F. Backhaus, H. Balder · Federal Research Centre for Cultivated Plants (Julius Kühn-Institut) · Germany
The International Symposium on Plant Health in Urban Horticulture, held in Braunschweig, Germany, from May 22 to 25, 2000, served as a platform to discuss deficits in the care and development of urban greenery and propose integrated concepts. Urban horticulture comprises diverse elements characterizing urban life, but many stress factors damage these components, and integrated concepts for maintaining and preserving urban green areas are lacking. The symposium aimed to jointly prepare future needs for action for the health preservation of urban green at an international level.
CommunityHealthPeri-urban agricultureSpectrophotometric determination of lead in the soil of allotment gardens in Lodz
2001B. Jankiewicz, B. Ptaszyński, Michael Wieczorek · Polish Journal of Environmental Studies · Poland (Lodz)
This study presents the results of lead determination in the soils of six allotment gardens located in various parts of Lodz. Lead was measured spectrophotometrically in the form of pink lead(II) dithizonate.
Contamination & food safetyHealthCommunitySpectrophotometric Determination of Cadmium (II) in Soil of Allotment Gardens in Łódź
2000B. Jankiewicz, B. Ptaszyński, Michael Wieczorek · Polish Journal of Environmental Studies · Poland (Łódź)
This study determined cadmium in the soil of six allotment gardens in Łódź, located in areas with different traffic patterns (city center and suburbs). Cadmium was detected in the form of cadmium (II) dithizonate using the extraction-spectrophotometric method. This research indicates the presence of cadmium contamination in urban allotment garden soils.
Contamination & food safetyHealthCommunityDevelopment of Potato Late Blight Epidemics: Disease Foci, Disease Gradients, and Infection Sources
1998M.J. Zwankhuizen, Francine Govers, J.C. Zadoks · Phytopathology · Netherlands
A study in Southern Flevoland, Netherlands, from 1994 to 1996, assessed inoculum sources of potato late blight. It found that 74% of early disease foci in commercial potato fields were linked to nearby infested refuse piles. Infected seed tubers, volunteer plants, and infested allotment gardens appeared to be of minor importance for late blight development in potato fields. However, in August 1994, infested organic potato fields became major mid-season infection sources, spreading the disease to adjacent conventional fields.

1988M. Krelowska‐Kulas · Food / Nahrung · Poland (Kraków)
An investigation using atomic absorption spectroscopy in Kraków, Poland, found that vegetables from urban allotment gardens had average levels of lead, cadmium, copper, zinc, and iron several times higher than control samples from farms 100 km away. In some cases, maximum levels of certain elements approached the admissible limit. However, average levels of lead and cadmium in pigs and cattle showed no reason for objection.
Contamination & food safetyHealthCommunityCadmium and lead in soils and crops from allotment gardens in the Netherlands.
1987P. van Lune · Netherlands Journal of Agricultural Science · Netherlands
A study analyzed cadmium (Cd) and lead (Pb) in soils and crops from 57 allotment gardens in potentially contaminated areas of the Netherlands. The median Cd and Pb concentrations in the soil samples were found to be higher than those in soils used for arable farming and horticulture. However, Cd and Pb concentrations in the crops themselves were normal.
Contamination & food safetyHealthA study of common crop pests in allotment gardens around Leeds
1979Howard J. Atkinson, Naomi Gibson, Harry C. Evans · Plant Pathology · United Kingdom (Leeds)
A survey of 140 growers across 12 allotment sites around Leeds, UK, identified a wide range of crop pests, with brassicas, potatoes, and carrots being more frequently damaged. Soil samples from 33 plots at 10 established sites and 6 plots at 2 new sites revealed potentially damaging levels of pale potato cyst nematode in 21 and 1 plots, respectively. Widespread overwintering populations of carrot fly larvae and pupae were also found in soil samples from eight sites.
