Title Biomarkers of environmental and workplace boron exposure
Bibliographic information Mar. 2008, Vol.5, No.3, p.141-147. Illus. 18 ref.
Abstract The purpose of this work was to identify an accurate, noninvasive biomarker of boron exposure that could be used in worker populations. Total daily boron exposure was determined from samples of 24-hr food and fluid intake, plus workplace personal air monitoring in boron workers and comparison groups in northern China during 2003 and 2004. Boron was also measured in blood, semen, creatinine-corrected post-shift urine and 24-hr urine. Total daily boron exposure (mg/day) averaged 41.2 for men working in the boron industry and 2.3 for the comparison group. Boron concentration in post-shift urine was correlated with total daily boron exposure, indicating that this value could be used as a biomarker of boron exposure in worker populations.
