Lead and health
The health effects from exposure to lead will depend on a variety of factors such as:
- a person's age
- the amount of lead they are exposed to and for how long
- if they have other health conditions.
Young children, including unborn babies, are at greatest risk of the health effects of lead exposure. Children are most often exposed to lead by swallowing items or soil containing lead or breathing in dust containing lead.
Adults are most often exposed to lead if they work in a job which involves lead-based activities.
If you suspect that you or a member of your family has been exposed to lead, visit your doctor for further advice. They may recommend that you have a blood test to measure the amount of lead in your blood.
Notification of elevated blood lead (>5 μg/dL)
The Department of Health and Human Services monitors cases of elevated blood lead levels in Victoria. The Public Health and Wellbeing Act 2008 requires that cases with blood lead greater than five micrograms per decilitre (>5 μg/dL) are notified to the department by pathology services (laboratories) within five days of initial diagnosis.
On 1 September 2018, amendments to the Public Health and Wellbeing Regulations 2009 came into effect which removed the requirement for medical practitioners to notify the department of cases of elevated blood lead >5µg/dL. The department remains authorised to capture additional information from medical practitioners to assist investigations, prevent further cases and to inform prevention strategies, as required. Medical practitioners can still of cases of elevated blood lead >5µg/dL.
Lead and gun shooters
