Fingernails, collected from five petrol attendants including the black marketers in major filling stations were digested using acid mixtures of hydrochloric acid and trioxonitrate (v) acid in the ratio of 1:1. From the result analysis, heavy metals such as Lead and Zinc are found in low levels in human fingernails. The low levels of concentration found in humans among petrol attendants are attributed to their exposure to environmental lead. Therefore petrol attendants have to take proper precaution so as to preserve their health.
