Arsenic accumulation in lentil (Lens culinaris) genotypes and risk associated with the consumption of grains

Abstract

Arsenic (As) is a toxic metalloid. As phyto-toxicity is manifested by its accumulation in different tissue types and subsequent growth inhibition in plants. Despite the vital role of leguminous crops in providing proteins to human diets, a little is known about the As accumulation in lentil. In this study, the rate of As uptake and transport from soil to root, shoot and grain of lentil as well as associated risks with the consumption of As contaminated food were examined. Biomass accumulation of lentil genotypes pardina, red chief and precoz drastically decreased when treated with As at 6 mg kg −1 concentration in comparison to 0 and 3 mg kg −1 As. Quantification of As concentrations following different treatment periods showed that As accumulation in roots and shoots of 0, 3 and 6 mg kg −1 As-treated lentil genotypes was statistically different. Arsenic content in grains of red chief genotype was found significantly lower than pardina and precoz. Moreover, As transport significantly increased in roots and shoots compared to the grains. Due to the high concentrations of As in biomass of lentil genotypes, animal as well as human health risk might be associated with the consumption of the As contaminated legume crops.

Overexpression of tomato RING E3 ubiquitin ligase gene SlRING1 confers cadmium tolerance by attenuating cadmium accumulation and oxidative stress

“…Heavy metal pollution is a major problem across the world, which not only affects crop production, but also causes harm to humans through the food chain (Viehweger, 2014, Zhou et al, 2016, Alam, Hoque, Ahammed, McGee, & Carpenter‐Boggs, 2019). Heavy metal(oid)s, such as cadmium (Cd), aluminium (Al), lead (Pb), and arsenic (As), are extremely toxic to both plants and animals, but they exist widely in the environment due to various anthropogenic activities (Alam, Hoque, Ahammed, & Carpenter‐Boggs, 2019; Mostofa et al, 2020; Zhao & Wang, 2019).…”

Visualising Silicon in Plants: Histochemistry, Silica Sculptures and Elemental Imaging

“…The study of metal(loid) uptake and accumulation in plants has received much interest in the last years [23][24][25][26], as they affect important physiological processes in plants, impact yield and, in the case of crops used for food and feed, can raise health-related issues. The study of metal(loid) accumulation in plants needs imaging to gain information on the sites of accumulation, on distribution and translocation routes.…”

Effects of biochar, farm manure, and pressmud on mineral nutrients and cadmium availability to wheat ( Triticum aestivum L.) in Cd‐contaminated soil

“…Retarded plant growth is a very typical symptom and can be seen in plants grown in Cd‐stressed soil (Ata‐Ul‐Karim et al, 2020a, 2020b). This may be attributed to the presence of toxic Cd in plant metabolism or the disruption of certain vital nutrients, leading to a large concentration of antagonistic heavy metals (Alam et al, 2019; Alsahli et al, 2020; Rizwan et al, 2016). It is very likely that the stunted growth of plants exposed to Cd could be attributed to the deficiency of critical elements by making insoluble Cd complexes (Gonçalves et al, 2009).…”
