New Mount Isa air quality report reinforces mitigation measures in place

Queensland Chief Health Officer Dr Jeannette Young

The health impacts of environmental lead in Mount Isa are widely recognised and their
management has been a priority for the State Government.

While these impacts cannot be entirely removed, various steps can and have been taken to
mitigate and minimise them.

A wide range of initiatives have been developed to promote living safely in a lead environment such as Mount Isa.

These include greening Mount Isa, undertaking promotional activities at local primary and
childcare centres/kindergarten and development of guidance material.

Information regarding the impact to health from exposure to lead, how exposure occurs,
precautionary actions and personal exposure surveillance options are readily available and
actively promoted in the Mount Isa community.

Glencore Mount Isa Mines over recent years also has strengthened its lead dust management programs to reduce community exposure as part of its new Environmental Authority.

So long as people are well informed and take the appropriate and recommended protective and mitigation measures to minimise their and their children’s exposure to lead, I believe Mount Isa remains a safe place in which to live.

Indeed, the range of recommendations suggested by the newly completed Lead Pathway Study – Air report into air quality at Mount Isa reinforce measures that are already in place and working to reduce the risks of lead exposure to the community.

As the chair of the Mount Isa Lead Health Management Committee, I am pleased to say many of these recommendations have been implemented over the past several years by Glencore Mount Isa Mines, by health authorities, the local council and the Lead Alliance which undertakes extensive education programs in the community.

These recommendations highlight the importance of:

  • The continued monitoring of blood lead levels in children at Mount Isa;
  • The need to undertake personal and home hygiene measures to minimise lead risks;
  • The maintenance and strengthening of existing controls to minimise the transfer of lead
    dust from the mine site at Mount Isa.

I note, however, that the data used in the Air Report is outdated and may not be reflective of
current conditions in Mount Isa and improvements in monitoring and technology.

For instance, the Mount Isa Lead Health Management Committee has noted an ongoing trend of improved air quality in relation to lead concentrations in Mount Isa since 2011, when the Department of Environment and Heritage Protection issued a new Environmental Authority for the mine which reflected contemporary air quality measures consistent with the national standard.

As a result, in the past few years I have been pleased to see that airborne lead levels at Mount Isa have been below national guidelines.

I also agree with the study finding that the risk of lead exposure to children in Mount Isa is mostly from ingestion of lead dust particles.

This underlines the importance of undertaking the recommended personal and home hygiene measures to minimise exposure to lead dust particles, as well as maintaining controls to minimise the transfer of lead dust from the mine site.

Thanks to the various education and intervention programs in place, I am pleased to see that
current blood lead level testing programs in Mount Isa indicate average blood lead levels recorded in tested children under five have been falling gradually since the initial children’s blood lead level survey in 2006-2007.

These results indicate that the lead health management programs and strategies we have put in place are having a positive impact and the Mount Isa Lead Health Management Committee will continue building on these.

For instance, in September 2016, finger prick testing for blood lead levels was introduced in Mount Isa to supplement the existing free venous blood lead tests that have been available for all residents through QML since 2010 and at Mount Isa Hospital for children under five since August 2014.

This form of testing is quicker and much less invasive than venous blood testing and will allow primary health care providers in Mount Isa, such as Gidgee Healing, also to offer tests to children, thereby broadening the blood lead level monitoring base.

The Lead Pathway Study – Air report was commissioned by Glencore Mount Isa Mines and prepared by the University of Queensland Centre for Mined Land Rehabilitation, in collaboration with the National Research Centre for Environmental Toxicology.

Mount Isa already has an extensive free blood lead level testing program available for residents.

Free blood lead level testing has been available since 2010 for all residents through QML and funded by Glencore Mount Isa Mines.

Blood lead level testing of children under five also has been undertaken at Mount Isa Hospital since August 2014.

These programs have been well-publicised.

In September 2016, finger prick testing for blood lead levels also was introduced in Mount Isa to supplement the existing free venous blood lead tests that are available through QML and Mount Isa Hospital.

Finger prick testing is currently being offered at four sites in Mount Isa, which are Gidgee Healing, Sonic Health Plus–Mount Isa GP Super Clinic, the North West Hospital and Health Service Child Health Services and the North West HHS Paediatric Outpatients.

This form of testing is quicker and much less invasive than venous blood testing and allows greater participation of young children, thereby broadening the testing base.

The aim is to offer testing at the same time as giving immunisations – at ages 6 months, 12 months, 18 months and 3½ years, but children can still be tested up to five years of age.

Thanks to the various education and intervention programs in place, it is pleasing to note that the current blood lead level testing programs in Mount Isa indicate average blood lead levels recorded in tested children under five are falling gradually since the initial children’s blood lead level survey in 2006-2007.

These results indicate that the lead health management programs and strategies we have put in place are having a positive impact and the Mount Isa Lead Health Management Committee will continue building on these.

Lead Pathways Study Air Report released

Mount Isa Mines has today released the Lead Pathways Study Air Report, concluding years of research and analysis into the pathways and potential health impacts of lead in the Mount Isa community.

In 2006, Mount Isa Mines commissioned The University of Queensland (UQ) to undertake a series of three studies to better understand the impacts of industrial and naturally occurring lead in the environment. The Land Report was released in 2009 and the Water Report was released in 2012.

The Air Report builds on the findings of the land and water studies and concluded that the potential exposure risk of children from inhalation was limited and mostly related to ingestion via hand to mouth activity.

The study reinforced the importance of Mount Isa residents taking active steps to minimise their exposure to lead and participate in regular blood lead level testing, particularly young children.

Led by UQ Associate Professor Barry Noller and Dr Jack Ng, the Air Report covered the period 2006 to 2013 and included a health risk assessment that focused on children under five years of age.

Chief Operating Officer for Glencore’s Copper Assets in Australia Mike Westerman said the studies were one of a number of inputs that Mount Isa Mines considered as part of its approach to continuous improvement of the site’s environmental performance.

“Our environmental initiatives are aligned with the Air Report’s recommendations and we are proactively supporting the Lead Alliance to raise awareness of the importance of maintaining a clean home, good personal hygiene and a nutritious diet,” he said.

“As modern regulations and accepted science has evolved, so has Mount Isa Mines.

“Since acquiring the operation in 2003, we have invested more than $500 million to improve our environmental performance.

“This has included industry-leading initiatives, particularly targeting air and water quality improvements.

“Over the past ten years Mount Isa Mines has reduced its total annual heavy metals emissions by between 60% and 96%.

“Today we manage one of the most comprehensive air quality monitoring systems of any Australian city, with each resident being within 1,200 metres of a monitoring unit.”

Mount Isa Mines operates within a Queensland Government-managed regulatory regime, with over 80 permits and authorities that include stringent reporting obligations.

“Our people and their families live locally and we call Mount Isa home, so the wellbeing of the community and the responsible operation of our mine will always be our priority,” Mr Westerman said.

“We urge residents to support the work of the Lead Alliance and be proactive about managing their exposure to lead.”

Mount Isa Mines will be implementing four new initiatives in 2017, including:

  • Boosting financial support of the Lead Alliance by $100,000 to help the organisation expand their reach and increase access to health programs in the Mount Isa community.
  • Providing an additional $50,000 to the Lead Alliance to develop a smartphone application aimed at driving positive behavioural changes with tips, reminders and blood lead level tracking.
  • Releasing a monthly Air Quality Dashboard via the Mount Isa Mines website to provide greater transparency about the operation’s performance against key environmental indicators.
  • Investing in additional targeted community health initiatives as part of the Glencore Community Program North Queensland, including those focused on Mount Isa’s Indigenous community.

Quick blood lead level results for young children

Parents will soon be able to get young children’s lead levels tested at primary health care providers and at the North West Hospital and Health Service (NWHHS), thanks to funding for lead testing machines.

The Office of the Chief Medical Officer has funded four machines, valued at approximately $4,000 each. Kerri O’Connor, NWHHS Nurse Unit Manager for Maternal Child and Youth Health, says the new testing method is much quicker and less invasive than a venous blood test.

“The point of care finger prick test with these machines will only take a few minutes, and the results will be available in 15 minutes. We are aiming to offer the test at the same time as giving immunisations – at age 6 months, 12 months, 18 months and 3 ½ years, but children can still be tested up to five years in age,” Ms O’Connor said.

The four machines will be used by Gidgee Healing, Sonic Health Plus- Mount Isa GP Super Clinic, and the NWHHS Child Health Services and Paediatric Outpatients. The lead level testing will be available at the beginning of October.

A year’s funding has also been granted for the test strips, which cost $15 for each patient. Ms O’Connor said the tests are reliable and have been used in Broken Hill for the past 20 years. She is hoping it will increase the amount of blood testing for lead in young children. “There has been a significant drop in children being tested for blood lead levels; we have very low testing rates at the moment.

“We want parents to get their children tested, if the lead level results are high, we refer the patient to a GP, and we look at their environment.

“We live in a lead-rich environment, and kids eat dirt – that’s just a fact of life – but there are changes to the environment that can be made, such as damping down dirt and dust in the yards, ensuring grass is grown to cover the dirt, and carrying out the measures advocated by The Lead Alliance: healthy eating, washing hands before eating and after handling pets, keeping pets outside, wet wiping surfaces in the home.”

Ms O’Connor said The Lead Alliance would be producing a poster about the new blood lead testing machines.

The Chair of The Lead Alliance, Robbie Katter, said the Alliance was thrilled to have the extra testing available in Mount Isa.

“We’ll be able to get more children tested, the test is not as invasive as the venous testing, and the results are immediately available.

“In the meantime it’s still very important for families to keep sticking to those positive messages such as the wet wipe message: wiping down all household surfaces regularly with a wet cloth and wet mopping hard floors; washing hands before eating, after playing outside and after handling pets.

“The eat well message is to reinforce the fact that good nutrition reduces the absorption of lead from the stomach into the blood stream, especially important with children,” Mr Katter said.

Queensland Chief Health Officer Dr Jeannette Young: In response to Mark Taylor research linking lead exposure and criminality.

The National Health and Medical Research Council has identified that at blood lead levels below 10 micrograms per decilitre (μg/dL), there is insufficient evidence about links between lead exposure and behavioural issues.

Many other contributing factors would influence criminal behaviour, such as socioeconomic status, education, parenting style and diet.

Conclusions cannot be drawn from studies reporting statistical associations between exposure to chemicals and broad social outcomes without a credible critical mass of scientific studies to support the claim and rule out other explanations.

The management of the health impacts of environmental lead in Mount Isa has been a priority for the state government.

Blood lead levels greater than 10 μg/dL can have harmful effects on many organs and bodily functions.

At blood lead levels between 10 μg/dL and 60 μg/dL, effects such as increased blood pressure, abnormally low haemoglobin, abnormal kidney function, long-term kidney damage and abnormal brain functions have been observed.

A wide range of initiatives have been developed to promote living safely in a lead environment such as Mount Isa. These include greening Mount Isa, undertaking promotional activities at local primary and childcare centres/kindergarten and development of guidance material.

Information regarding the impact to health from exposure to lead, how exposure occurs, precautionary actions and personal exposure surveillance options are readily available and activity promoted in the Mount Isa community.

The Living With Lead Alliance was established in 2008 to undertake initiatives and information programs relating to lead and lead exposure within the Mount Isa community. The Mount Isa Lead Health Management Committee – chaired by myself as Chief Health Officer – was established in 2012 to provide additional guidance, oversight and strategic
direction to the management of lead health risks in Mount Isa.

A free voluntary blood lead level testing program has been in place in Mount Isa through QML laboratories since 2010. A blood lead level testing program for children under five also runs at Mount Isa Hospital.

The results of the various testing programs in 2015 indicate a steady reduction in average blood lead levels recorded in tested children under five since extensive community surveys undertaken in 2006–2007 and again in 2010.

These results indicate the intervention and information strategies we have put in place over the years are having some effect and we will continue building on these.

Furthermore, there have been no recorded cases of acute lead toxicity in children for more than 20 years.

In addition, from 1 January, Queensland’s mandatory blood lead notification level has been reduced from 10 μg/dL to 5 μg/dL.

This reduction was recommended last year by the National Health and Medical Research Council and accepted by the Queensland Government.

The Living with Lead Alliance response to ‘Misled about lead: assessment of online public health education material from Australia’s lead mining and smelting towns’, by Donna Green and Marianne Sullivan

The following statement may be attributed to Mr Robert Katter, Member for Mount Isa and Chair of the Living with Lead Alliance.

Since 2008, the Living with Lead Alliance (the Alliance) has been implementing a long-term strategy to promote the successful coexistence of community and industry at Mount Isa.

Our objectives have been two-fold: both to raise awareness about the risks and potential health effects of lead in children and adults and inform the community about best-practice prevention of lead exposure.

The Alliance is committed to delivering this information to the community as broadly as possible and in a variety of ways to reach the widest possible audience.

Over the years we have delivered a number of key initiatives in the areas of school education programs, annual expert seminars, broad advertising campaigns, backyard improvement programs, and local partnerships to deliver nutritional education and support.

For instance, each year, the Alliance brings leading Australian toxicologist and emergency physician Dr Mark Little to Mount Isa to deliver seminars to the community and playgroups.

Dr Little discusses the toxic effects of lead to the body, the risk of brain damage to babies and children and the potential health impacts on adults.

He also discusses the best way to reduce the risk of elevated blood lead levels and his presentation is available on our website (PDF).

In 2016, the alliance and Dr Little will be delivering information and talks to all day care centres and kindergartens in Mount Isa.

In 2016, the alliance and Dr Little will be delivering information and talks to all day care centres and kindergartens in Mount Isa.

I encourage all parents to attend and become more informed on the issue of lead within our community.

In October 2015, Townsville Public Health Unit Director Dr Steven Donohue released data detailing the results of blood lead level testing of Mount Isa children.

The results have shown that, since 2006, average blood lead levels in tested Mount Isa children under the age of five have been falling gradually.

The data also showed the number of children under five that are being tested for blood lead levels in Mount Isa has been increasing – especially since the introduction of opportunistic testing at Mount Isa Hospital in August 2014.

I believe the work of the Living with Lead Alliance over the past few years, including the range and quality of information we deliver to Mount Isa residents, has contributed both to the gradual reduction in blood lead levels in tested children and the increase in the number of children tested.

This is a positive result for the Alliance and for the Mount Isa community. Importantly, we remain committed to helping promote this downward trend.

The Alliance is guided by the Mount Isa Lead Health Management Committee and the National Health and Medical Research Council as to the information we deliver to the community.

We will review any opportunities identified in the Green-Sullivan study for the way in which we inform the Mount Isa community on the risks of elevated lead levels in children, pregnant women and families.

It is essential that all residents, parents and children are aware of how to minimise the risk by implementing the alliance’s key messages: Wet wipe, wash and eat well.

Advice for Mount Isa residents on living safely with lead from the Living with Lead Alliance

The Living with Lead Alliance would like to inform the community about how to live safely with lead during the current drought conditions.

It is essential that we all work together to ensure that we reduce the possible risk of elevated blood lead levels in our children and be vigilant in reducing lead dust in our homes.

Due to the current dry conditions, it is difficult to keep water up to grassed areas and many lawns are now just bare soil. The Alliance recommends that you keep very young children and crawling babies away from these areas as much as possible. It is essential that you and your children wash their hands regularly during the day after playing outside, petting animals and especially before eating. To reduce bare soil areas in your yard you can use mulch and pavers in and around a child’s play area. Mulch will also help keep water evaporation to a minimum.

There has been a lot of wind which is stirring up dust. To reduce dust in the home, keep windows closed as much as possible, regularly wet wash and wipe worktops and benches, especially food preparation areas, wet mop hard floor surfaces regularly. Remember to rinse the cloth and mop during the cleaning process.

Keep yard shoes and work boots outside to reduce the amount of dust you bring into the home. Try and keep dogs outside, ensure they have access to shade and drinking water, wash and groom them regularly.

Pin a baby’s dummy to the baby’s clothing to prevent it falling on the floor and picking up dust. Crawling babies tend to put things into their mouths, so try to keep toys and floors dust free.

Breast-feeding mums need to ensure that their blood lead levels are as low as possible as lead can be transferred to a baby through breast milk.

Free blood lead testing is available at QML Pathology
13a Isa Street, Monday to Friday 7.30am to 2pm, no appointment necessary.
