Synopsis
Lead is a heavy metal used in manufacturing various batteries, alloys, plastics and protective coatings. It is not required for human health, and can be toxic when ingested or inhaled. Once in the body, lead circulates in the blood; while most is excreted, some can remain in the tissues, organs and bones.
The research evidence on the effects of low-level lead exposure suggests that anything over 10 μg/dL (micrograms per decilitre) is of concern.
The public statement and information paper reiterate the message that it is important to limit exposure to lead in the community.
Information Paper—Blood Lead Levels for Australians
The information paper is intended for health care practitioners and policy makers. It provides background to lead exposure and articulates goals and recommendations for Australia.
Public Statement—Blood Lead Levels: Lead Exposure and Health Effects in Australia
The public statement from the NHMRC discusses the evidence and makes recommendations on what we should aim for regarding blood lead levels in Australia and also gives some practical advice on minimising exposure to lead.
NHMRC recommendations on lead exposure
- All Australians should have a blood lead level below 10 μg/dL (micrograms per decilitre).
- All children’s exposure to lead should be minimised.
- All women are advised to minimise their exposure to lead both before and during pregnancy and also while breastfeeding.
