Arsenic found in many US red wines, but health risks depend on total diet

(University of Washington 29 September 2015) A new UW study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed US drinking water standards. But health risks from that naturally-occurring toxic element depend on how many other high-arsenic foods and beverages, such as apple juice, rice, or cereal bars, an individual person eats.

Researchers accidentally create material that sucks mercury out of water

ABC News : The World Today Lucy Carter 19 October 2015

Researchers at Flinders University have accidentally discovered a way to remove mercury from water using a material made from industrial waste and orange peel.  The substance could be used to literally suck up mercury at sites where it is contaminating water.

The substance changes colour when it comes into contact with and absorbs mercury, which means it could also be used to detect whether waterways are polluted.   Dr Jack Ng sees big potential for this new substance.

Lawyer urges more health testing as part of Oakey chemical contamination investigation

ABC News Ellie Sibson 9 October 2015

A lawyer representing Oakey residents affected by a chemical contamination at the local Army aviation base says more testing needs to be carried out, after the release of recent blood tests.
The Defence Force is investigating what effect toxic chemicals used in firefighting foam at the base had on the environment and human health.
It has commissioned blood tests on local residents who have been drinking bore water.
Lawyer Peter Shannon said some of those had come back with highly elevated levels of heavy metals.

Australia’s most dangerous streets revealed by school testing

The Sydney Morning Herald Catherine Armitage October 8, 2015

Accidents, illness, strangers: danger to children takes many forms. But, for brain damage caused by toxic mining metals, the streets closest to the mines in Broken Hill, Mount Isa and Port Pirie must rank as the most dangerous in Australia.
Children in these mining and smelting cities exposed to high levels of lead, arsenic and cadmium are more than twice as likely to have developmental delays than the national average, new research shows.
These children are at a much higher than average risk of lifelong neurobehavioural deficits. And those who live closest to the mines are at highest risk.

Data used in Mount Isa environmental lead exposure study outdated public health director says

ABC News Zara Margolis 8 October 2015

A north Queensland public health director says he believes data used in a recent research paper on the management of environmental lead exposure in Mount Isa is out of date and misleading.
Earlier this week, the ABC reported on a study that cited almost 5 per cent of children under the age of five in Mount Isa had higher than recommended blood lead levels.
Dr Steven Donohue from the Mount Isa and Townsville Public Health Unit said that information was more than five years old and latest figures showed average blood lead levels in tested children were declining.

Health expert questions efforts to manage Mount Isa lead exposure amid calls for more data

ABC News 6 October 2015

A north Queensland researcher says more data needs to be made available about environmental lead exposure in Mount Isa.

Public health expert Dr Malcolm Forbes has reviewed how government, industry and health officials have dealt with the issue, finding long-standing inconsistencies and a lack of available information.

He said about 5 per cent of children under the age of five in Mount Isa have higher than recommended blood lead levels, which was still too many.
