TL;DR: Estimated daily intake (EDI) and THQs for Cd and Pb of rice and vegetables exceeded the FAO/WHO permissible limit and bio-accumulation factors of heavy metals were significantly higher for leafy than for non-leafy vegetable.

TL;DR: In this article, a field experiment was carried out to evaluate the phytoextraction abilities of six high biomass plants (Vertiveria zizanioides, Dianthus chinensis, Rumex K-1 (Rumex upatientia × R. timschmicus), Rumex crispus, and two populations of Rumex acetosa) in comparison to metal hyperaccumulators (Viola baoshanensis, Sedum alfredii).

TL;DR: Investigation of heavy metal contamination levels of soils, vegetables, and rice grown in the vicinity of the Dabaoshan mine found concentrations of Cu, Zn, Pb, and Cd in paddy soil exceeded the maximum allowable concentrations for Chinese agricultural soil.

TL;DR: A pot experiment was conducted in a greenhouse to evaluate the phytoremediation abilities of four forage grasses with respect to soil Cd and Zn pollution, finding that Pennisetum americanum (L.) LeekexPennisetum purpureum Schumach and P. atratum could be useful for phytoextraction of either or both Cd, Zn, and S. guianensis had no remediation capability.

TL;DR: The results suggest that the accumulation of heavy metals in specific animal organ of tissues could not be neglected, although transfer of metals to chicken from plant and insect was limited.
