“…Also those of [16], who had a similar results for concentrations of Zn in root tissues of eighteen emergent wetland plant species exposed to Zn in hydroponic culture. Lead is mainly resided (more than 50%) in the aerial organs for cherry tomato plant ( Figure 5); a same result was found by [17] for B. pilosa and T. Minuta.…”

The phytoavailability of lead and chromium in cherry tomatoes Lycopersicon esculentum was studied both at the level of different parts of the plant (roots, stem, leaves and fruits) and at the level of its concentration in water and cultivation soil of. Two experiments are thence carried out by planting in bioponics, in a patented BIOTOP device, plants which are exposed via their root system to concentrations of 5 ppm, 10 ppm and 20 ppm of each contaminant (lead or chromium) in a nutrient solution. The results show that lead accumulates mainly in the roots with a significant amount as to allow its translocation into the stem and leaves, while only a small amount reaches the fruit. The results also show that when the concentration increases the lead content in the roots also increases, but decreases in the fruits with three floral bouquets. Conversely, the chromium substance decreases in the roots and increases in the fruit. Based on these results, we note that the average distribution of lead in the edible part of the plant is much higher than that of chromium, and also lead presence in the plant is higher compared to that of chromium.

“…The rhizospheric soil was collected from the three host plant species Bidens pilosa L., Tagetes minuta L. and Sorghum halepense (L.) Pers. Although not all these species were found at all sites, these were the most abundant in the study area and have been previously studied for Pb accumulation in both field and experimental conditions (Cid et al, 2016;Graziani et al, 2016;Salazar and Pignata, 2014;Salazar et al, 2016a;Salazar et al, 2016b;Sosa et al, 2016).…”

“…This is an area characterized by a former battery recycling factory that once operated here from 1984 to 2005 (31°33′ 34.02″S; 64°11′9.05″W, whose smelter was closed down due to functional problems associated with a lack of emission control and an inadequate waste disposal. Further information about this area can be found in Salazar and Pignata (2014) and Salazar et al (2016a).…”

Metal pollution in soils is an issue of global concern, and lead (Pb) pollution is considered to be the most serious type. The arid and semi-arid areas of Northwest China are rich in Pb ore resources. In this study, four native crops [wormwood (Artemisia capillaris), dandelion (Taraxacum mongolicum), alfalfa (Medicago sativa), and plantain (Plantago asiatica L.)] that grow naturally around tailings slag in a mining area in Northwest China were selected to screen their ecological restoration impacts on Pb-contaminated soil. In pot experiments, four different metal lead pollution gradients (0, 2, 3, and 5‰ w/w) were set, and crop growth indexes such as plant height, root length, and biomass, together with the changes of soil Pb content in different tissues and organs before and after planting were analyzed. The results showed the difference in the amount of accumulated Pb in relation to the level of Pb content in the soil. It was found that wormwood and plantain have great potential as remediation plants for soil metal lead pollution in the arid and semi-arid lead bearing mining areas of Northwest China.
