In response to community concerns about dust emissions from the Cadia gold mine in Central West NSW, NSW Health has worked closely with the NSW Environment Protection Authority (EPA) to investigate potential health impacts of exposure to heavy metals in the surrounding area.
NSW Health commissioned an independent “Deep Dive” investigation and convened the Cadia Mine Expert Health Advisory Panel to assess any potential health risks and provide analysis, advice and recommendations to the NSW Chief Health Officer.
The Panel has released a Summary Report which details the methodology and results of the Deep Dive Investigation. A Summary Statement is also available, which outlines the Panel’s key findings and recommendations.
NSW Health commissioned an investigation involving 14 community volunteers from seven properties near the Cadia gold mine. The investigation included environmental testing of households and comprehensive clinical assessments by an expert clinical toxicologist.
Environmental testing involved sampling indoor dust, soil, water (from rainwater water tanks and household taps), and home-grown produce from participants’ homes. Information about participants’ daily routines and potential sources of exposure to heavy metals was also collected to help build a clear picture of possible exposure pathways.
Each participant also underwent a clinical assessment by a clinical toxicologist.
The results from the environmental and clinical assessments were reviewed by the Cadia Mine Expert Health Advisory Panel. The Panel consisted of experts in toxicology, respiratory medicine, air quality, food safety, water quality, medical laboratory techniques and public health.
The Panel reviewed the environmental and clinical assessments and found no definitive evidence of health impacts from heavy metal exposure among volunteers who were assessed.
The investigation indicated that community exposure to heavy metals was low, at concentrations consistent with expected background levels and below health-based guidelines.
The Panel concluded that there was no indication that broader community testing is required at this time.
More information about the investigation can be found in the Summary Report.
The investigation was initiated in response to concerns raised by members of the community about possible health risks from exposure to dust and heavy metals linked to mining activities at the Cadia gold mine.
To better understand possible exposure pathways and assess health impacts, NSW Health invited community members to volunteer to participate in a detailed investigation that included environmental sampling and clinical assessments.
NSW Health will continue to provide advice and support to local GPs in the region surrounding Cadia.
NSW Health will also work closely with the EPA, which is leading regulatory oversight of dust emissions at the Cadia mine.
If you have health concerns or think you may have had high exposure to dust or heavy metals, please speak to your GP, who can assess your individual circumstances.
