The remarkably low p-value (<0.001) for lead (Pb) indicates a noteworthy distinction in lead absorption between spinach and maize. Specifically, maize exhibits a significantly greater uptake of lead than spinach, indicating a possible risk of lead buildup in maize crops. The remarkably low p-value (<0.001) for zinc (Zn) shows a substantial variation in zinc absorption between spinach and maize. Maize has a much greater zinc uptake than spinach, suggesting that the two crops have different zinc uptake mechanisms and accumulation strategies.
