Mt Isa Lead Research Media Backlash
New Research Article Slammed in Local Media for Linking Mt Isa Mine and Smelter Emissions with Lead Exposure
Summary of related research and media articles by Lan Nguyen, Masters of Business in Human Resources Management, University of Technology, Sydney, and Intern, The LEAD Group Inc
A survey in 2008 found 11 per cent of children in Mt Isa had elevated blood lead levels. For a long time mining company Glencore Xstrata and the state government have argued the high levels of lead contamination in the environment were largely a natural occurrence. However, a recent study published in Environmental Pollution provides strong links between the combined effects of historic and contemporary lead-emitting site operations in this mining and smelting Queensland town.
The scientific report, primarily completed by Professor Mark Taylor, looked at samples of soil, dust and air from inside and outside homes and public places in Mount Isa between 2005 and 2008. As summarised by Macquarie University Newsroom, this new and compelling study challenges Xstrata’s claims about naturally occurring lead on the following grounds:
These findings are considered as relevant to other mining areas in Australia and elsewhere all over the world where there is a serious risk of harm and cause of contamination due to lead mining and smelting operations. As the significant risk still remains within the urban atmosphere, Professor Taylor further stresses that there is a need for immediate action and better control.
In response to this study, while Mount Isa Mayor Tony McGrady said every resident in this mining area recognised and acknowledged the issue of both natural and “industrial mineralization” [a term with an unstated meaning*], the global mining giant Xstrata revealed that it was doing its own research into air quality and human health risk assessment and attempting to improve its environmental performance.
Commenting on the “negative” Environmental Pollution report, Councillor McGrady was quoted in the local newspaper as saying: "I take it as an offence personally as I have raised two children in this city and they're as smart as anybody else in this state so I don't see any adverse impacts of living with lead in the city as long as people take care with hygiene."
[*Editor’s note: Wikipedia defines Mineralization (geology), as “the hydrothermal deposition of economically important metals in the formation of ore bodies or lodes… Mineralization may also refer to the product resulting from the process of mineralization. For example, mineralization (the process) may introduce metals (such as iron) into a rock. That rock may then be referred to as possessing iron mineralization.” That doesn’t sound like a process that could be anything but natural. Wikipedia also defines Industrial minerals as “geological materials which are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals). They are used in their natural state or after beneficiation either as raw materials or as additives in a wide range of applications… Typical examples of industrial rocks and minerals are limestone, clays, sand, gravel, diatomite, Kaolin, Bentonite, Silica, Barite, Gypsum, and Talc.” But surely the Mayor and Xstrata who also use the term “industrial mineralization”, are not referring to these industrial minerals.]
