“…Because they are essential for plant growth, some HMs are absorbed by the root and are translocated to the shoot by specific transport mechanisms that, in some circumstances, mediate the movement of nonessential HMs such as Pb and Cd. Both the activity and the selectivity of these mechanisms are finely regulated by specific genetic traits, which implies that the uptake and accumulation of soil bioavailable HM fractions in the leaves vary greatly among plant species and also among different genotypes within the same species [12][13][14]. Excluding specific groups of plant species known as accumulator or hyperaccumulator plants, most (>90%) of the absorbed HMs are retained in the roots and thus, only a minor fraction is translocated and accumulated in the shoot [15].…”

Cattle and pig manure contain useful mineral nutrients (N, P, and K) and are therefore used as organic fertilizer. However, excessive applications of manure can cause environmental problems and threaten animal and human health because these materials also hold significant amounts of heavy metals, particularly Cu and Zn. To assess the potential risk due to the increased concentrations of heavy metals (Cu, Mn, Zn, and Cr) in a harvested crop, two maize hybrids were grown in pots on four different soils with three different fertilisers (urea, pig manure, and cattle manure). Both soil and manure characteristics influenced the heavy metal concentrations in the plant shoots. Organic fertilisation strongly interacted with the soils and, in general, reduced the shoot content of Cu, Mn, and Zn. A preliminary assessment of the heavy metal balance of the agricultural systems based on the intensive livestock production and maize cultivation showed that the potential soil enrichment of the long-term application of livestock manure arises mainly from the application of pig slurries that have a high content of Cu and Zn. The time required to apply an amount of metal that is equal to the initial soil content is 60–300 years for Zn and 240–450 years for Cu, depending on the soil type and the initial heavy metal content.

“…Much research on phytoremediation has been done using native plant species (Lorestani et al, 2011;Aziz et al, 2011;Barbafieri et al, 2011), hyperaccumulating plants (Revathi et al, 2011;Ji et al, 2011;Nazir et al, 2011), and agricultural crops (Mojiri, 2011;Poniedzialek et al, 2010;Garg and Kataria, 2009). In these studies, phytoremediation capacity was evaluated as heavy metal *Corresponding author.…”

The phytoremediation of soil contaminated with lead (Pb), zinc (Zn) and copper (Cu) from industrial wastewater discharge in a farming village near Hanoi City was investigated. The first growing plant species tested were the Spanish needle, water primrose, common willow herb, and water spinach. Uptake by roots and shoots per unit land area for each species was calculated and compared. The uptake of the heavy metals per unit area was higher in shoots than in roots for each plant species and was affected by the higher biomass production of the shoots. For the roots, the uptake did not differ by species, but did differ by heavy metal. For the shoots, the uptake differed by both plant species and heavy metal with the common willow herb having higher Pb and Zn uptake compared to those of the other three species. For the common willow herb, the uptake of heavy metal was in order of Pb > Zn > Cu. The results indicate that common willow herb has a superior phytoremediation capacity among the plants tested, particularly for the uptake of Pb.

“…For example, the response of two genotypes of soybean to Cd addition differed significantly when treated with K (Shamsi et al, 2010). Alternatively, the use of phytoremediation-the use of hyperaccumulator plants to "mine" heavy metals out of the soilcould also be a worthwhile approach where disposal of the plant material is not a problem (Boularbah et al, 2006;Poniedzialek, Sekara, Jedrszczyk, & Ciura, 2010).…”

Potassium amendment increases biomass and reduces heavy metal concentrations in Lablab purpureus after phosphate mining

et al. 2017

Agricultural pursuits in post‐mining environments are becoming increasingly important globally as many regions are challenged with food insecurity and post‐mining land‐use legacies. Although there are many advantages for agricultural production at post‐mining sites, these substrates have abiotic and biotic challenges for plant growth, including poor fertility, heavy metals, and lack of beneficial soil microbes. We investigated whether increased potassium (K) levels in a post‐phosphate mining substrate on Christmas Island, Australia, could improve plant productivity and reduce heavy metal concentrations. Addition of K (80 and 160 kg ha−1) significantly increased plant biomass and enhanced root growth and mycorrhizal fungal colonisation rates. Potassium amendment was also strongly correlated with lower heavy metal concentrations in leaf material. Clearly, K is the critical limiting nutrient for legumes in post‐phosphate mining sites on Christmas Island for enhancing biomass and health. We hypothesise that heavy metals were either being diluted in a larger biomass and/or healthy plants could also select against heavy metal uptake; however, this requires further investigation of the mechanisms involved. These results have significant global ramifications for sites transitioning from mining to agriculture.
