Corn absorbs a greater concentration of cadmium than spinach does, indicating that maize may be able to accumulate cadmium from the soil more effectively. The cadmium (Cd) p-value (0.003) shows a significant difference in cadmium absorption between maize and spinach. The extremely low p-value (<0.001) for chromium (Cr) indicates a significant difference in chromium absorption between spinach and maize. While spinach has a significantly greater chromium uptake than maize, there may be a danger of chromium buildup in maize crops.
