Heavy metals and metalloids accumulation in common beans (Phaseolus vulgaris L.): A review

Toxic Elements in Beans from Zhejiang, Southeast China: Distribution and Probabilistic Health Risk Assessment

“…The uptake of heavy metals by plants depends on several factors, including soil properties such as pH, phosphate, and organic matter. Furthermore, high concentrations of heavy metals could be toxic to plants due to the increased generation of reactive oxygen species and oxidative stress [7].…”

“…There are multiple potential mechanisms that may elucidate the correlations observed among various elements in beans [7]. Firstly, positive correlations could arise from their concurrent existence in identical geological formations, resulting in their accumulation within the same samples.…”

“…Furthermore, genetic factors and environmental conditions play a role in determining the uptake and accumulation of toxic elements. For instance, Cadmium accumulation in plants can increase with decreasing soil pH [7].…”

Preconcentration and selective extraction of trace Hg(ii) by polymeric g-C3N4 nanosheet-packed SPE column

“…5 Long-term exposure to Hg(II) can permanently damage the developing foetus, kidneys, and brain. [6][7][8] To address this concern, the US Environmental Protection Agency has set a maximum limit of 2.0 ppb for Hg(II) in consumable water, and the World Health Organisation (WHO) emphasizes the importance of monitoring and evaluating such harmful metals. 9,10 However, directly detecting trace levels of Hg(II) in natural samples is challenging using common techniques like atomic uorescence spectrometry, X-ray uorescence, cold vapour atomic absorption, graphite furnace atomic absorption spectroscopy, inductively coupled plasma optical emission spectroscopy, and inductively coupled plasma mass spectrometry due to elemental interferences and sampling limitations.…”
