Lead [Pb] is one of the important heavy metals responsible for human health deterioration. The Delhi NCR host a number
of companies related to mining, mineral, engineering, machines, construction, etc. The presence of industries exposes the
residents to the harsh chemicals. Lead is excreted in the water sources by the industries in the Delhi NCR region. The lead
from the industries reaches the human body via the water cycle. The present study attempts to assess the health risk from
the presence of lead in the population of Delhi NCR associated with age, gender, residential area, and disease in DelhiNCR using GTA-Atomic Absorption Spectroscopy. Correlations were found between the lead concentration in blood and
water. The lead concentration in blood and lead concentration in water also showed correlations with the region from
which the samples were taken.
