Urinary arsenic, cadmium, manganese, nickel, and vanadium levels of schoolchildren in the vicinity of the industrialised area of Asaluyeh, Iran
Asaluyeh is one of the most heavily industrialised
areas in the world where gas, petrochemical, and many downstream
industries are located. This study aims to survey the
biomonitoring of four metals and one metalloid in children
living in the vicinity of Asaluyeh area. To do this, we analysed
the creatinine-adjusted urinary levels of arsenic (As), cadmium
(Cd), vanadium (V), manganese (Mn), and nickel (Ni) in
184 elementary schoolchildren (99 boys and 85 girls) living in
Asaluyeh and compared them with a reference population.
The comparisons were done for two seasons (spring and fall).
The results showed that in the case area (Asaluyeh), the levels
of As, V, Mn, and Ni were significantly higher and that of Cd
was not significantly higher than the reference city for both
seasons. The mean concentration of metal(loid)s in Asaluyeh
(case) and Sadabad (reference) area as μg g−1 creatinine was
As 2.90 and 2.24, V 0.06 and 0.03, Mn 0.28 and 0.25, Ni 0.54
and 0.29, and Cd 0.31 and 0.28 in spring and As 3.08 and
2.28, V 0.07 and 0.03, Mn 0.30 and 0.26, Ni 0.91 and 0.30,
and Cd 0.36 and 0.31 in the fall. Seasonal variations played a
key role in determining urinary metal(loid) concentration, as
we saw the significant level of As, Cd, V, and Ni in fall than in
spring. With regard to the impact of gender on the absorption
and accumulation of urinary metal(loid)s, boys showed higher
levels of the studied elements, especially for As, than girls as
outdoor activities are more popular among boys. Due to the
values being lower than those reported in literature, more research
is needed on various population groups and other exposure
sources in order to judge whether living in the vicinity
of the gas and petrochemical industries in Asaluyeh is a threat
to nearby residents
