J. Shaham et al., THE CORRELATION BETWEEN BLOOD AND URINE LEVEL OF CADMIUM AND NASAL AND PARANASAL SINUSES DISORDERS, International archives of occupational and environmental health, 65(1), 1993, pp. 190000091-190000093
Over exposure to cadmium may produce numerous adverse health effects,
including changes in the nasal mucosa. Cadmium levels were measured in
blood and urine samples taken from 106 workers who were exposed to hi
gh levels of cadmium and nickel in a cadmium nickel battery plant. Pat
hological results were observed in 46% and 51% of the blood and urine
samples respectively. A positive association was found between clinica
l nasal complaints and pathological levels of cadmium in blood (P=0.00
6) and urine (P=0.045) samples. All the workers underwent sinus X-rays
and 63% of them were abnormal. No correlation was found between patho
logical sinus X-rays and pathological cadmium level in blood and urine
samples. A positive correlation was found between clinical nasal comp
laints and abnormal sinus X-rays. The prevalence of sinus X-ray abnorm
alities in an asymptomatic general population is 33% as compared to 63
% in our study. This difference is highly significant statistically (P
<0.0001). Our result shows a possible harmful effect of cadmium on the
paranasal sinuses
