“…of leaf area) on the leaves of tomato and zucchini (Table 1) highlighted a significant higher amount of most pollutants (As, Ba, Cu, Pb, Sb, Sn, V, Zn) deposited on both crops grown nearby the road (ROAD/10) compared with the ones located far from it (ROAD/60), therein confirming the deposition of these elements from road traffic as well as their high bioavailability and leachibility from soils (Imperato et al 2003;Madrid et al 2002;Wong et al 2006). As a matter of fact, anthropogenic metals have been reported to be both easily bio-available in soils and easily diffused into the vegetable cuticle, through the stomata (Bianchini et al 2012).…”

Urban agriculture is increasingly popular for social and economical benefits. However, edible crops grown in cities can be contaminated by airborne pollutants, thus leading to serious health risks. Therefore, we need a better understanding of contamination risks of urban cultivation to define safe practices. Here we study heavy metal risk in horticultural crops grown in urban gardens of Bologna, Italy. We investigated the effect of proximity to different pollution sources such as roads and railways, and the effect of the growing system used, that is soil versus soilless cultivation. We compared heavy metal concentration in urban and rural crops. We focused on surface deposition and tissue accumulation of pollutants during 3 years. Results show that in the city, crops near the road were polluted by heavy metals, with up to 160 mg per kilogram of dry weight for lettuce and 210 mg/kg for basil. The highest Cd accumulation of up to 1.2 mg/kg was found in rural tomato. Soilless planting systems enabled a reduction of heavy metal accumulation in plant tissue, of up to −71 % for rosemary leaves.

“…Among the four metals, soil Pb and Zn contents significantly correlate to the distance from the city center (p<0.01), indicating the content of these two heavy metals in surface soil increased with the samples approaching city center. It was reported in several literatures that contents of Cd, Pb, Cu, and Zn in soils tended to increase as plots were sampled closer to the older inner city (Li et al 2001;Mellor 2001;Madrid et al 2002;Li et al 2004;Zhang 2006;Yesilonis et al 2008). Chen et al (2005b) studied Pb and Cu contents in soils of 30 Beijing parks and revealed there were significant correlations between the locations (older historic center and newer districts) and contents of Pb and Cu.…”

“…One of the main characteristic of urban soil is that it is often contaminated by various kinds of pollutants such as heavy metals. Due to proximity to humans, accumulation of harmful substances in urban soils is of great concern (Manta et al 2002;Maas et al 2010).Strong accumulation of heavy metals such as Cu, Cd, Zn, Pb, and Hg in urban soils has been reported by many researchers (Mellor 2001;Madrid et al 2002;Morton-Bermea et al 2009). Heavy metals may be transferred to human bodies by way of ingestion, inhalation, and dermal contact, or through the food chain (Biasioli et al 2006;Vrscaj et al 2008).…”

Abstract:The pollution of urban soil with heavy metals caused by traffic activity is increasingly becoming a great threat to human health and environmental quality. This paper presents results of research of lead (Pb) and cadmium (Cd) distribution in land on playgrounds situated near busy streets in Cracow (Poland). Samples of sand and soil were collected from the most top layer (0-10 cm). Concentrations of examined metals are: Pb from 6.80 to 54.04 mg/kg and Cd from 1.60 to 2.61 mg/kg, respectively. The highest concentrations were found in sampling points near the busiest roads, and are particularly visible in the case of lead concentration in soil samples. For sand samples, metal concentrations are much lower. Although the results have not determined a high degree of soil's contamination, they indicate the problem of the children's exposure to toxic metals. Urban soil should be monitored particularly in such special places as playgrounds.
