The aim of the Ten for them project is to lower the blood lead levels of Port Pirie's children, between the ages of 0 and 4, to below the World Health Organisation recommendation of ten micrograms of lead per decilitre of blood. A recommendation that's also supported by Australia's National Health and Medical Research Council.

Enormous progress has been made in addressing this environmental and health issue. The four main areas of action remain:

  • To minimise lead emissions from the smelter to the community
  • To minimise lead exposure in the community to children
  • To ensure effective community consultation and communication
  • To ensure best practice monitoring of lead-in-air emissions and children's blood lead levels in the community

In August 2011, 75.6 per cent of children under the age of five had blood lead level of less than 10. This is a significant improvement on children's blood lead levels at the commencement of the tenby10 project in 2006.
