Comparative Analysis of Heavy Metals Concentration in Soil and Vegetable (Vernonia amygdalina) Collected from Two Sampling Sites (Farmland and Dumpsite) and the Effect on Plant DNA

Different studies have shown that Vernonia amygdalina is enriched with proteins, fats, fibres, amino acids, minerals vitamins, and carbohydrates but no record yet on the level of heavy metals in collected from Ojota (dumpsite) Badagry (control) Lagos state. Samples V. were analyzed for using standard method, while differences concentrations t-test analysis at significance set p=0.05. The results recorded mg/100g content (Cd, Cr, Cu, Pb Zn) plant across two stations not significantly different (p>0.05). Zn leaf stem (100.157 ±1.351, 45.743± 3.664) respectively dumpsite higher than farmland (91.468 ± 2.386, 35.505 ±1.662). Also, root (73.671 ±2.205) was (69.515 2.312). All values N, P K leaf, roots bitter both sites (p<0.05). most frequent nutrient K, followed by N least P. In contrast, contained highest then stem. DNA band showed alteration. conclusion, leaves rich (N, P, K) though their dumpsites. However, being within permissible limits imply it safe human consumption.
