In general, the order of heavy metal content in different vegetative parts of vegetable plants is as follows: Root > Leaves > Fruit. This is because heavy metals tend to accumulate more in the root system of plants, particularly in the root cortex and vascular tissues. The heavy metals are then transported to the leaves through the plant's vascular system. However, the concentration of heavy metals in fruits is usually lower compared to the roots and leaves. It is important to note that heavy metal content can vary depending on the specific vegetable plant species and environmental conditions.
