Geochemical speciation and bioaccumulation of trace elements in different tissues of pumpkin in the abandoned soils: Health hazard perspective in a developing country

Effects of long-term banana cultivation on trace elements deposition in soil ecology

“…The translocation capacity of trace elements from soil to the various plants' parts of the banana is better studied using the translocation factor (TF) (Islam et al 2021b). The index of TF was computed using Eq.…”

“…Average extents of Cu, Cd, As, and Pb in topsoil of banana fields of the present study were higher than the ASV (average shale values) standard (Turekian & Wedepohl 1961), BV (background value) in Bangladesh (Kashem & Singh, 1999) and the standard of Dutch soil quality (VROM 2000) (Table 1), indicating their contamination in soil and may destroy the ecology of banana fields soil. Islam et al (2021b), conducted study in soils of Bangladesh and they stated that toxic elements contaminated waste from burning or metals processing sites and imbalanced use of pesticides to the agricultural fields were responsible for advanced heights of As, Cu, Pb, and Cd and that might be the reasons for elevated trace elements in soil of banana fields. In the current study, an anomalous intensity of Cd was observed where the merit of this element was 17.3 times higher than the average shale standards of Cd in soil (Table 1).…”

“…Interestingly, Cu was detected in substantial amounts in plant leaves, possibly as a result of the chloroplasts' photosynthetic activity, plant respiration and assists in plant metabolism of carbohydrates and proteins. Since Cu regulates enzymatic activity for lignin formation and chloroplasts are the typical component of leaves, substantial Cu buildup is anticipated in plant leaves (Islam et al 2021b).…”

“…To establish the connection between metals in topsoil and their agreement into the numerous tissues of plants grown on the same land for long time, bio-concentration factor (BCF) and translocation factor (TF) are indexical methods that are usually employed by researchers (Yoon et al, 2006;Igwe et al 2014;Islam et al 2021b). There should be concern about the ecotoxicological status of soil used for banana cultivation and human health hazards brought on by the buildup of hazardous substances in different parts of banana plants.…”

“…According to research by Islam et al (2021b), vegetables, particularly pumpkin, produced close to a waste disposal facility in an urban region of Bangladesh are significant sources of toxic substances that pose a danger to human health. There should be concern about the long-term cultivation of banana in the urban soil around the ancient Pundranagar of Bangladesh for excessive metals accumulation in soil and plants that cause public health defects.…”
