The comparative study of some heavy metals accumulation of watermelon commonly consumed in Kano and Zaria environmental. The nutritional and mineral levels in watermelon fruits are generally important to support the nutritional requirement of man that is why its demand necessary to check the concentration of the ions it contains. Laboratory analysis like preparation of standard for test metals were carried out to check the levels of these heavy metals in Kano and Zaria watermelon fruit. Mineral analysis based on the results it is found that Kano watermelon fruit is more nutrition and less watery but has higher level of heavy metal accumulation especially from lead given by World Health Organization (WHO) which may be due to soil type and inherent parent materials of the region. While the Zaria watermelon fruit is more watery and less nutritive compared to that of Kano but have all the heavy metal accumulations within acceptable ranges/standards given by the World Health Organization (WHO).
