Port Pirie - Tenby10 (Lead Levels)

Tenby10 (Lead Levels)

Lead smelters contribute to several environmental problems, especially raised blood lead levels in some of the town population. The problem is particularly significant in many children who have grown up in the area. There is a government project to address this. Nyrstar plans to progressively reduce lead in blood levels such that ultimately 95% of all children meet the national goal of 10 micrograms per decilitre. This has been known as the tenby10 project. Community lead in blood levels in children are now at less than half the level that they were in the mid 1980s.

The Port Pirie smelter has a project underway to reduce lead levels in children to under 10 micrograms per decilitre by the end of 2010.

"The goal we are committed to achieving is for at least 95% of our children aged 0 to 4 to have a blood lead level below ten micrograms per decilitre of blood (the first ten in tenby10) by the end of 2010 (the second ten in tenby10)."

Higher concentrations of lead have been found in the organs of bottlenose dolphins stranded near the lead smelter, compared to dolphins stranded elsewhere in South Australia. The health impacts of these metals on dolphins has been examined and some associations between high metal concentrations and kidney toxicity were noted.
