“…2). Similarly, Zn concentrations in bread wheat ranged from 20 to 40 mg kg − 1 in a study of 243 wheat genotypes cultivated in normal agricultural soils(Nikolic et al, 2016). , the average value of between 26.3 to 35.0 mg kg − 1 , suggest Zn in wheat grain grown in Kurdistan is in the range of Zn concentrations reported globally for wheat grown in calcareous soils.Approximately 88% of the surveyed wheat grain samples contained Zn concentrations below the value recommended for human nutrition of 41.6 mg kg − 1 by the USDA (USDA Food Composition Databases, 2018).…”

A survey of wheat grain from 120 fields in Sulaimanyah province, Kurdistan region, Iraq was undertaken in 2017. We evaluated the concentrations of phosphorus (P), Zn and phytic acid (PA) and the estimated Zn bioavailability in wheat grain grown in the calcareous soils of the region. Concentrations of P in wheat grain were higher than the recommended value of 3570 mg kg− 1; PA was within the range of other countries but Zn concentration in 88% of wheat grain samples fell below the value recommended for human nutrition of 41.6 mg kg− 1. Bioavailable Zn intake (mg d− 1) was estimated assuming bread consumption of 300 g day− 1 in the region. Considering PA and Zn intake suggested only 21.5 ± 2.9% of whole grain flour Zn was bioavailable. Thus the effective Zn intakes from whole wheat was only 1.25–2.05 mg d− 1 for the local population. Typical dietary Zn was below recommended levels (11 mg d− 1), due to low soil Zn uptake by wheat and the large concentrations of PA in wheat grains, probably from over-use of phosphate fertilizer.

“…The northern part of Serbia (Vojvodina Province) is considered to be a Zn deficient area (Manojlović and Singh, 2012). In a study conducted in Serbia, the Zn contents in most of the soil samples (total n=157) were above the specified limit of 0.5 mg kg -1 (DTPA extractable Zn), and only in 13% of the samples mostly collected in the Vojvodina Province below this limit (Nikolic et al, 2016). According to Marijanušić et al (2017) the measured Zn contents in all of the samples of forage crops (alfalfa and grasses) in Vojvodina and East Serbia were below 15 mg kg -1 .…”

Biofortification of forage crops has an important role in improving the quality of plants used for animal nutrition. The field experiments were conducted in three consecutive years in Subotica, Serbia, in order to investigate the effect of Se, Zn, and Cu foliar fertilization on the yield, Se and Zn contents and nutrient efficiency, as well as on other mineral compositions of alfalfa hay. The treatments were as follows: i) control without fertilization, ii) 5 g Se ha-1 , iii) 10 g Se ha-1 , iv) 0.5 kg Zn ha-1 , v) 1 kg Zn ha-1 , vi) the combination of these two elements (0.5 kg Zn ha-1 and Se 10 g ha-1) and vii) 2% Cu solution. The application of Se, Zn, and Cu had no effect on dry yield or on crude protein, P, K, Ca, Mg, Fe, Mn, Mo, and Co contents in alfalfa hay. However, Se, Zn, and Cu fertilization significantly increased the contents of Se, Zn, and Cu in alfalfa hay. The results showed that Se and Zn contents in plant biomass were significantly correlated with the applied doses of Se (r=0.99) and Zn (r=0.99). The production years of alfalfa and the weather conditions proved to be significant factors in fertilization efficiency.

“…On the other hand, the basic content of their food are cereals and grains, which usually contain zinc. This may indicate, as has been shown in other countries, that the soil in the Al Gadarif region is rather deficient of zinc [12]. Another possibility is that during baking or cooking zinc is transferred to a chemical form that is not easily absorbed by the human body [13].…”

Iron deficiency anaemia is a major health problem worldwide, but may be complicated in underdeveloped nations by deficiencies of other micronutrients with consequences for adequate treatment. The World Health Organization (WHO) estimates that 2 billion people-over 30% of the world's populationare anaemic, approximately 50% of cases of anaemia are considered to be due to iron deficiency. Aim: Since a combined deficiency of trace elements has great consequences in the approach of this problem, zinc status was assessed in blood of iron deficient anaemic patients in Sudan representing sub-Saharan Africa and compared with Dutch anaemic patients representing Western Europe. Method: Zinc as well as iron were measured with instrumental neutron activation analysis (INAA) in 22 Sudanese anaemic patients and four controls as well as in 17 Dutch anaemic patients and four controls. Result: In the Sudanese patients very low concentrations of zinc were measured, 3 ± 1 mg/L compared to a control group of healthy individuals (5 ± 1 mg/L), while all Dutch patients had normal zinc levels (5 ± 1 mg/L). When matched for haemoglobin level, the Sudanese patients still showed lower zinc concentrations. Even in the Sudanese patients without a known history of malnutrition and in patients with the anaemia of chronic disease zinc levels were significantly lower than in the controls. A positive correlation was observed between Fe and Zn in blood of the Sudanese subjects (r=0.654), while there is no or a very week relation between Fe and Zn in blood of the Dutch group (r=0.08). The low level of Fe and Zn for the Sudanese group might be ascribed to the poor intake of these two nutrients with the main dietary food (cereals) in this area. Conclusion: In iron deficiency anaemia in Sudanese patients, a deficiency of zinc should be taken into account in case of supplementation.
