Soil and plant samples of Telfairia occidentalis, Manihot esculenta, and Oryza sativa were collected from Enyigba, Ameri, Ameka, and Ishiagu mining districts in Ebonyi State and analyzed for the concentration of Pb, Zn, Cu, Cd, and Cr using the Atomic Absorption Spectrophotometer technique. Transfer Factors, Daily Intake of Metals, and Health Risk Index were used to evaluate the potential health hazards in the study area. The results indicated that Zinc has the highest Transfer Factor, ranging from 1.0 to 2.0, especially in pumpkin, Telfairia occidentalis, with a concentration of 5.9 ppm. The results of the Daily Intake of Metals indicated that the intake of Zinc, Lead, and Cadmium by children in the study area was 6.9×10⁻⁴ mg/kg/day, 6.24×10⁻⁴ mg/kg/day, and 9.4×10⁻⁶ mg/kg/day, respectively, in the contaminated vegetable samples. Similarly, the results of the Health Risk Index indicated that the potential health hazard in the study area ranges from 0.000221 to 0.023 for Zinc, 0.031 to 0.176 for Lead, and 0.00949 to 0.0232 for Cadmium, all below the threshold value of 1, indicating that the study area is safe, but the cumulative effect of the exposure and the presence of toxic metals in the edible parts of the plant require serious public health concern.</span></p> <p><strong><span lang="EN">Keywords:</span></strong><span lang="EN"> </span><span lang="EN">health risk assessment, transfer factor, daily intake of metals, heavy metals, food crops, bioaccumulation, Nigeria.</span></p> <p><strong><span lang="EN">Title:</span></strong><span lang="EN"> Health Risk Assessment of Heavy Metal Transfer from Contaminated Soils to Food Crops in Pb-Zn Mining Communities of Southeastern Nigeria</span></p> <p><strong><span lang="EN">Author:</span></strong><span lang="EN"> Osayande A.D.</span></p> <p><strong><span lang="EN-US">International Journal of Recent Research in Interdisciplinary Sciences (IJRRIS)</span></strong></p> <p><strong><span lang="EN-US">ISSN 2350-1049</span></strong></p> <p><strong><span lang="EN-US">Vol. 13, Issue 1, January 2026 - March 2026</span></strong></p> <p><strong><span lang="EN-US">Page No: 59-64</span></strong></p> <p><strong><span lang="EN-US">Paper Publications</span></strong></p> <p><strong><span lang="EN-US">Website: www.paperpublications.org</span></strong></p> <p><strong><span lang="EN-US">Published Date: 26-February-2026</span></strong></p> <p><strong><span lang="EN-US">DOI: <a href="https://doi.org/10.5281/zenodo.18788971">https://doi.org/10.5281/zenodo.18788971</a></span></strong></p> <p><strong><span lang="EN-US">Paper Download Link (Source)</span></strong></p> <p><strong><span lang="EN-US"><a href="https://www.paperpublications.org/upload/book/Health%20Risk%20Assessment%20of%20Heavy%20Metal-26022026-7.pdf">https://www.paperpublications.org/upload/book/Health%20Risk%20Assessment%20of%20Heavy%20Metal-26022026-7.pdf</a></span></strong></p> |
