Biological exposure index
- Determinant
- Lead in blood
- Sampling Time
- Not critical
- BEI
- 10µg/dL (0.48µmol/L) for males and for females not of reproductive capacity, pregnant, or breastfeeding.
Biological Agent Reference Value (BRV) for lead in whole blood of females of reproductive capacity, pregnant, or breastfeeding of 3µg/dL (0.14µmol/L).
- Notes
- Ideally, pregnant women, breastfeeding women, or women planning to become pregnant should have no exposure to lead at all. This is because the developing foetus is extremely susceptible to lead.
The BRV is based on the 95th percentile blood lead levels of women aged 18–69 in New Zealand. The BRV is not a BEI and is intended only to be an indicator that workplace exposure may exist and should be investigated as there is no recognized threshold for neurotoxicity for new-borns and infants.
Management of suspension of a worker and return to work based on biological monitoring should be supervised by a competent medical practitioner. - Year adopted
