N2 - Food chain alteration with heavy metals is
one of the most important concerns in public health and
food safety. This research reports the first monitoring of
heavy metals in the Adolfo Ruiz Cortines dam in Alamos,
municipality of Sonora, Mexico. Concentrations of Arsenic
(As), Lead (Pb), Mercury (Hg) and Copper (Cu) were
analyzed by atomic absorption spectrophotometry coupled
to the hydride generation system. A health risk assessment
was carried out calculating cumulative doses of As and Pb
in tap water, Oreochromis niloticus (known as tilapia) and
dam sediments. The results of this research reveal that themost important source of arsenic in humans is Oreochromis
niloticus and for lead it is the consumption of tap water.
Children are the most affected population, reaching a
cumulative risk index for exposure to Pb of HIc = 3.30 and
for As of HIc = 7.35. This study estimated that communities
close to Adolfo Ruiz Cortines dam, present a potential
health risk due to the consumption of O. niloticus, tap water
and dam sediments contaminated with Pb and As.
