Abstract

Heavy metals contamination in edible plants poses significant risks to human health and environmental sustainability. This study evaluates heavy metal contamination in Amaranthus hybridus L. (spinach) collected from three sites: Nyabunkaka River, Kogin Sarki, and Mayo-Gwoi River in Jalingo, Taraba State, Nigeria. The study aimed to determine the levels of lead (Pb), cadmium (Cd), chromium (Cr), zinc (Zn), copper (Cu), nickel (Ni), manganese (Mn), and cobalt (Co) in spinach samples using Atomic Absorption Spectrophotometry (AAS). Results revealed that Pb concentration in spinach from Nyabunkaka slightly exceeded the FAO permissible limit, while Cd, Cr, Zn, Cu, Ni, Mn, and Co levels in all samples were below FAO reference values, indicating minimal contamination risks. These findings highlight the potential environmental pollution near Nyabunkaka River and suggest that spinach from the selected areas remains largely safe for human consumption, except for slight Pb contamination. The study emphasizes the need for continuous monitoring to ensure food safety.

Abstract

This experiment was carried out to Assess mineral, and vitamin constituents of SAMPEA-11 and SAMPEA 20T cowpea cultivars. Plant materials were purchased from the Institute for Agricultural Research, Ahmadu Bello University, Zaria, Nigeria. Minerals were determined using Atomic Absorption Spectrometer while vitamin contents were analyzed using High-Performance Liquid Chromatography. SAMPEA 20T had high potassium concentration of 8.920 ppm, while copper was 0.059 ppm. For SAMPEA-11, potassium also had the highest concentration at 6.760 ppm, followed by phosphorus, 3.626 ppm and calcium, 1.630 ppm. Lower concentrations of iron, zinc, copper, and magnesium were noted in both cultivars. In SAMPEA 20T, two vitamins were detected: Vitamin B1 and Folate with concentrations of 2.123 mg and 11.060 mg, respectively. In SAMPEA-11, three vitamins were detected: Thiamine, Folate, and Vitamin E with concentrations of 12.450 mg, 23.459 mg and 3.047 mg respectively. The analysis of SAMPEA-11 and SAMPEA 20T cowpea cultivars shows a significant presence of potassium among the minerals, and a predominant presence of Folate, with notable concentrations of Thiamine and Vitamin E. The variety of nutrients highlight the nutritional value and potential health benefits of these cowpea cultivars.
