Bioaccumulation and Distribution of Lead, Zinc, and Cadmium in Crops of Solanaceae Family

Abstract

Comparative research has been carried out to determine the quantities and accumulation of lead (Pb), zinc (Zn), and cadmium (Cd) in the vegetative and reproductive organs of crops of the Solanaceae family (tomato, pepper, and aubergine) as well as to identify the possibilities of growing them on soils contaminated by heavy metals. The analyses were carried out by inductively coupled plasma-atomic emission spectrometry after dry ashing. Heavy metals have an impact on the development and productivity of the crops of the Solanaceae family. The high anthropogenic contamination impedes the normal development and fruit-bearing ability of the pepper and aubergine plants, and in the case of tomatoes, it led to an increased assimilation of heavy metals without reducing the yield and the quality of the production of tomatoes. Crops from the Solanaceae family, tomato, pepper, and aubergine plants, could be cultivated on soils having low and medium levels of contamination of heavy metals, because they do not show a tendency to accumulating Pb, Zn, and Cd in their fruits, which could still be used for consumption.

Increasing the Knowledge on the Management of Cu‐Contaminated Agricultural Soils by Cropping Tomato (Solanum Lycopersicum L.)

“…Especially interesting were the results obtained for soil Sollana where this CF kept relatively constant. These results extend those obtained by other authors (Cintra et al ., ; Angelova et al ., ), because low translocation rates of Cu to tomato ( S . lycopersicum L.) fruits were obtained not only at low to medium levels of Cu contamination in soils but also at high to very high levels of Cu contamination in soils because, for most of the soils, low Cu concentrations were determined in fruits yielded at these concentrations (Table ).…”

Reducing Cadmium Accumulation in Fresh Pepper Fruits by Grafting

“…In addition, members of the Solanaceae, Chenopodiaceae, Cruciferae, and Asteraceae are considered to be robust accumulators of Cd (Kuboi et al, 1986). Fruit vegetables, such as the tomato (Solanum lycopersicum L.), pepper (C. annuum L.), and eggplant (Solanum melongena L.), are characterized by rather low rates of heavy metal translocation to the fruit (Angelova et al, 2009). The impact of grafting on the uptake of heavy metals by fruit vegetables has not been well investigated.…”

Biochar Effect on Cadmium Accumulation and Phytoremediation Factors by Lavender (<i>Lavandula stoechas</i> L.)

“…Mostly, plants accumulate them in the root tissues or the aboveground biomass [13]. Lavender samples of root, stems and leaves were analyzed to assess the issues of accumulation of cadmium in the vegetative organs.…”
