Abstract
Long-term exposure to arsenic has been associated with manifestation of skin
lesions (melanosis/keratosis) and increased risk of internal cancers (lung/bladder). The
objective of the study described here was to determine the relationship between exposure
of arsenic through drinking groundwater and urinary arsenic excretion among adults ≥15
years of age living in Khairpur district, Pakistan. Total arsenic was determined in
drinking groundwater and in spot urine samples of 465 randomly selected individuals
through hydride generation-atomic absorption spectrometry. Spearman’s rank correlation
coefficient was calculated between arsenic in drinking groundwater and arsenic excreted
in urine. The median arsenic concentration in drinking water was 2.1 µg/L (range: 0.1–
350), and in urine was 28.5 µg/L (range: 0.1–848), respectively. Positive correlation was
found between total arsenic in drinking water and in urine (
r
= .52,
p
< .01). Urinary
arsenic may be used as a biomarker of arsenic exposure through drinking water.

Abstract
The study described in this article was designed to estimate the dietary intake of
lead, cadmium, and mercury due to the shellfish consumption of the population in Nha
Trang City, Vietnam. The lead, cadmium, and mercury concentrations in the shellfish
consumed popularly by the Nha Trang population were investigated by inductively
coupled plasma-mass spectrometry from May 2008 to January 2009. The lead, cadmium,
and mercury concentration ranges in shellfish are equal to 0.008–0.083, 0.013–0.056, and
0.028–0.056 mg/kg, respectively. The dietary intake of these elements was determined by
a total diet study. The heavy metals intake was estimated for six subpopulation groups:
men and women aged 18–29, 30–54, and ≥55. The dietary intakes of lead, cadmium, and
mercury by the Nha Trang population are currently well below the provisional tolerable
weekly intakes of lead, cadmium, and mercury, respectively. Therefore, no risk exists
concerning the levels of exposure of Nha Trang consumers to the contaminants studied
due to shellfish consumption.
