We measured the serum concentration of iron, zinc, copper and bromine in fifty malnourished children and twenty one healthy controls using energy dispersive X-ray fluorescence spectrometry. The mean ages for the study group and controls were 27.06 and 29 months respectively. The mean weights of the study and control groups were 7.32 and 12.05 +/- 3.07 kilogrammes respectively. The serum iron, zinc, copper and bromine mean levels in the study and control groups were Fe 14.6 (9.9) Zn 12.5 (11.9) Cu 16.5 (21.2) and Br 59.1 (63.0) micromoles per litre. Analysis of variance between the study group and controls showed a significant fall in copper levels even when adjusted for age sex and weight differences (F = 4.6586 p < 0.05). The wide distribution of concentrations of Iron noted in the malnourished children is probably due to haemolysis and rapid catabolism. The role of bromine in nutrition is yet to be established.

Although iron-doped hydroxyapatite (Fe-HAP) and its composites have been reported to immobilize arsenic (As), lead (Pb), and cadmium (Cd), its practical application is limited by the inefficient release of iron and phosphate. In this study, Ochrobactrum anthropic, a phosphate-solubilizing bacterium isolated from a lead-zinc smelting site, was employed to enhance multi-heavy metal immobilization in Fe-HAP-amended soils. O.

Bacillus velezensis SQR9 or Trichoderma harzianum NJAU4742-amended bioorganic fertilizers might significantly improve the soil microbial community and crop yields. However, the mechanisms these microorganisms act are far away from distinctness. We combined amplicon sequencing with culturable approaches to investigate the effects of these microorganisms on pear tree growth, rhizosphere nutrients and microbial mechanisms.

This study examines the complex interactions between wheat cultivar selection and fortification with NaFeEDTA and ascorbic acid (AA) on the bioavailability of iron (Fe) and zinc (Zn) in whole wheat flour (WWF) and chapati. Nineteen hexaploid wheat cultivars were rigorously assessed for their intrinsic Fe and Zn profiles, including total content (TC), solubility (S), and bio-accessibility (B), utilizing an in-vitro gastrointestinal model. Significant variations (P < 0.
