During the last decades a phenomenal progress has been made by different toxic metals(TM)in several ecological areas.Many sites have been identified as hazardous waste(HW)sites because of the presence of elevated concentrations of these elements.Concerns regarding heavy metal(HM)contamination in the environment affecting all ecosystem components,including “soil-plant-animal-human” chain(SPAHC).Triticale has a high biomass production(10-15 t ha-1)potential(BPP).It can be important role in soil fertility,human food and animal foraging as a fodder-crop too with a high carbohydrate,protein content,and in HMs pytoremediation high-technologies(PHT).Triticale is harvested mostly for forage but there is a small market for pancake mixes and crackers due to a savory,nutty flavor.Etanol plants will pay a premium for the crop over barley since it has more starch and no hull,making alcohol production more efficient.Al,Cu,Sr,Pb and Zn are considered to be a nonessential elements for plant.These metals are effectively tent to absorbed in the root,leaf and seed systems and change the crop productivity.Field experiments were carried out on an acidic sandy brown forest soil at Nyírlugos in East-Hungary from 1962 to 2014.Soil geochemical parameters were as follows before trial set up: humus 0.6%,pH(H2O)5.8,pH(KCl)4.6,total N 32.8 mg kg-1,AL(ammonium lactate soluble)-P2O5 43 mg kg-1,AL-K2O 52 mg kg-1.The experiments involved 32 NPKCaMg treatments in 4 replications giving a total of 128 plots.N levels were 0,50,100,150 kg ha-1 yr-1,P2O5 and K2O 0,60,120,180 kg ha-1 yr-1,CaCO3 0,250,500,1000 kg ha-1 yr-1 and MgCO3 were 0,140,280 kg ha-1 yr-1.Pb and Zn element contents of leaf and straw were significant before flowering time and ranged between 0.4-1.5 mg*kg-1 and 26-39 mg*kg-1,respectively in 1998.Al,Cu,Sr and Zn degree of grain at harvest were moved among 4.4-9.3 mg*kg-1,4.3-5.6 mg*kg-1,3.2-10.2 mg*kg-1,36-50 mg*kg-1.These survey shows crop has potential Al,Cu,Sr,Pb and Zn bioaccumulation might for upground parts of the plant and they can enter to Food Chain(FC)and pollution it.
