Antimony in blood and urine of infants.
OBJECTIVE
To establish a reference range for antimony in the serum and urine of infants in the first year of life.


METHODS
100 infants were selected randomly from the population. Each infant had a single blood and urine sample taken. Antimony was assayed using inductively coupled plasma mass spectrometry.


RESULTS
The reference range for antimony in the serum of infants in the first year of life was established as 0.09-0.25 microgram/l. The upper 95% centile for urinary antimony, corrected for creatinine, in the same population was 2.6 ng/mg creatinine. There was a very weak correlation between the serum and urine concentrations.


CONCLUSIONS
This study confirms the presence of low concentrations of antimony in the serum and urine of healthy infants.
