“…Although the least content of Mn was incorporated with this compost, compared with other composts, other factors could have had influence such as the interaction between chemical elements, as the highest nitrogen concentration was established in grain as well. The Mn concentration in winter wheat grain determined in the experiment was marginally higher compared with those indicated by many other researchers, namely 18-50 mg kg -1 (Karatas et al, 2006;Bermudez et al, 2011). The increase of Pb, Ca and Ni concentrations in plant produce is undesirable (Lubytė et al, 2001) Pb concentration in winter wheat grain was established to be higher and varied more substantially compared with spring barley.…”

In 2013-2014, research was carried out on a Bathihypogleyi-Haplic Luvisol (LVh-gld-w) soil with predominant sandy loam and pH KCl 4.9-5.2 with a view to finding out how composts produced from sewage sludge, green waste and biogas production waste influenced grain and straw yields of winter wheat grown in the first year after compost incorporation and spring barley grown in the second year after incorporation as well as the concentrations of nitrogen, potassium and heavy metals in grain and straw. The field experiment was conducted in the fields of Elmininkai Experimental Station (Anykščiai distr., Eastern Lithuania) of the Lithuanian Research Centre for Agriculture and Forestry. The investigations proved that the composts incorporated without mineral fertilizer did not increase grain and straw of winter wheat grown in the first year after incorporation. During the second year, the composts increased the spring barley grain yield as follows: biogas -by 72.9%, green waste -68.6%, cattle manure -58.9% and sewage sludge -45.2%. The application of composts on the background of mineral fertilizers did not significantly increase winter wheat and spring barley grain and straw yields compared with mineral fertilizers. The concentration of chemical elements in plants depended on the compost degradation process in soil. During the first year after incorporation of composts, nitrogen (N) concentration in winter wheat grain was increased by biogas, and during the second year -by sewage sludge and green waste composts in spring barley grain. Potassium (K) concentration in winter wheat and spring barley straw was increased by cattle manure, biogas and sewage sludge composts. During the first year, all composts increased phosphorus (P) concentration in winter wheat straw. The concentrations of heavy metals (Cd, Ni, Pb, Zn, Mn and Cu) in grain and straw were close to the background levels. The composts used in the study increased the content of nickel in winter wheat and spring barley grain and straw somewhat more significantly.

Rice and wheat are rich sources of essential elements. However, they may also accumulate potentially toxic elements (PTE). Bulgur, the popular alternative to rice in the eastern Mediterranean, is produced by processing wheat, during which PTE content may change. This study determined PTE concentrations in rice and bulgur collected from 50 participant households in the City of Izmir, Turkey, estimated ingestion exposure, and associated chronictoxic and carcinogenic human health risks. Comparison of the determined concentrations to the available standard levels and the levels reported in the literature revealed that Cd, Co, and Pb in rice might be of concern. The estimated health risks of individual participants supported this result with exceedance of respective threshold or acceptable risk levels at the 95th percentile.Population risk estimates indicated that the proportion with higher than the threshold or acceptable risk is about 10%, 24%, and 12% for Cd, Co, and Pb in rice, respectively. Results of this study showed that health risks associated with PTE exposure through bulgur consumption are lower than those of rice, and below the threshold or acceptable risk levels.

“…Owing to their non-biodegradable, non-thermal degradable and persistant toxic characters, heavy metals are easy to stay in soil and may enter into ground water [6,12], be taken up by plants and accumulate in human body through food chain, then posing threats to human health [2,11]. As the second largest crop in the world, wheat as the main food resource for locals is widely grown in northern China [1].…”

In order to investigate the effects of planting density on accumulation of heavy metals in spring wheat, a weak alkaline agricultural district mainly contaminated by heavy metals Cu, Zn, Pb and Cd, was chosen in 2014. Five planting densities (114×10 4 , 174×10 4 , 249×10 4 , 369×10 4 and 519×10 4 plants hectare -1 , respectively) were designed and the level of heavy metals in soil and in various parts (root, stem, leaf, husk and grain) of spring wheat were detected, and then the health risk to human health was assessed via hazard quotient. The results indicate that concentrations of Pb and Cd in each part of spring wheat plant are negatively correlated with planting density, similar but weaker trends are observed for those of Cu and Zn. The hazard quotient of heavy metals through food chain is markedly reduced with increasing planting density, especially for Pb and Cd at higher planting densities (369×10 4 and 519×10 4 plants hectare -1 ). Conclusively, the present study shows that suitable planting density could be a feasible cultivation method for ensuring the safety of wheat products and human health on slightly polluted alkaline soils.
