“…Since Cr content was below MAC value in the whole study, none of these two categories (garden and field vegetable soils) is quality limited by this element. When calculating the concentration of risk for Cr, it is suggested that difference from Cr III and Cr VI (which is much more toxic) should be made (Boim et al, 2016). Results obtained in this study are very similar to extensive study of Joimel et al (2016), where soil characteristics were compared by the manner of usage: forest, grassland, cultivated, orchards and vineyards, urban vegetable gardens and industrial land uses.…”

“…The degree and direction of the slope from the interstate toward the soil plot is important factor (Trammell et al, 2011). Exposure of the human population to potentially toxic elements (PTE), such as lead (Pb), copper (Cu), chromium (Cr), nickel (Ni) and zinc (Zn) in agricultural soils may occur through inhalation of particles or through the consumption of soil or vegetables and fruit grown in contaminated soils (Boim et al, 2016). The concentration of heavy metals in urban grown vegetables is strictly related to the site in the city where plants are grown.…”

Urban gardening is an activity that has been rapidly increasing. The aim of this study was to point out the common mistakes in cultivation practices made by producers on small city areas. Total of 96 individual plots under vegetable crops were sampled (56 from garden plots of the city of Novi Sad, and 40 from field plots in the suburbs). There was no significant difference in the content of organic matter between these two groups of tested soils. The contents of readily available P2O5 and K2O were significantly higher in garden soil than in the field plots for production of vegetables. According to the content of pseudototal copper, 39% of samples belonged to the category of critical concentration and/or above MAC in the urban soil. Obtained results prove the pollution of small area gardens due to high anthropogenic effect of excessive use of mineral fertilizers and copper-based fungicides.

Characteristics of Cadmium and Lead Accumulation and Transfer by Chenopodium Quinoa Will

Potentially toxic elements are persistent in the environment and plants have the ability to absorb and transfer them from soil in edible parts. The objectives of this study were to characterize the distribution of Cd and Pb in quinoa tissues and to investigate their accumulation and transfer from irrigated water in edible parts of quinoa. For the purpose of this study experiment and simulated pollution in the form of different metal concentration in water that was used for irrigation was designed. Distribution of metals in quinoa were determined and analyzed in seed formation and maturation stage. Bioaccumulation and translocation factors were calculated to characterize the efficiency of quinoa to absorb metals. The results of our study indicated that quinoa adopts potentially toxic metals from substrate but does not accumulate them. The potential of such a conclusion is useful for exploring the use of quinoa as lead and cadmium excluders.

“…Where: %clay = average clay content in the soil database (%); %SOM = average organic matter content in the soil database (%); %claymean = average clay content; %SOMmean = average content of organic matter; A, B, C = variables specific to each metal as adopted by Swartjes et al (2007). We used 2% SOM and 35% Clay following Boim et al (2016).…”

“…Ba and Zn had the highest risk concentration, while Cu and Ni represented a risk concentration almost 15 times lower. The reference oral dose (RfDo) for Ba and Zn is one order higher than the RfDo for Cu and Ni, which contributes to a lower risk during the consumption of lettuce contaminated with Ba and Zn when compared to Cu and Ni Boim et al (2016). used data from the literature to derive the risk concentrations for Cu, Cr, Pb, Ni and Zn in humid tropical and temperate regions.…”
