Around 200 people attended the public meeting after the release of a Queensland Health report showing one in 10 children in the city were at risk of health problems due to high lead levels.

A study of 400 children in Mt Isa aged under four showed that 11.3 per cent had elevated blood lead levels, greater than the World Health Organisation's (WHO) safety standard of 10 micrograms per decilitre.

Two samples were two to three times above it, and indigenous children were four times more likely than non-indigenous children to show high blood lead levels.

The family of six-year-old Stella Hare has already served a notice of claim for damages on Xstrata, its subsidiary Mt Isa Mines, Mt Isa City Council and the Queensland Government over the girl's brain and nervous system impairments allegedly linked to lead exposure.

Chief operating officer for Xstrata Copper North Queensland, Steve de Kruijff, said the company would "strongly" defend the legal action.

The family's lawyer, Damian Scattini, rejected the report as a "snow job" and said the meeting was stacked in favour of Xstrata.

"Unfortunately, as expected, (the meeting) was a PR exercise, and unfortunately, presents a solution that the population should live with it," Mr Scattini said to ABC Radio outside the meeting.

"That's just a recipe for another generation of children being poisoned and left with brain damage."

Queensland Health says the lead contamination risk is manageable through diet and good hygiene.
