QUT researchers find charged particles more common near major highways

Brisbane Times | May 26, 2015 | Jorge Branco

Toxic vehicle emissions near major highways are more likely to stick in your lungs thanks to an electrical charge, researchers have found, and some Brisbane homes are close enough to busy roads to be of concern.

A host of cancer-causing chemicals commonly found in diesel fuels, including benzene, can better bond with the walls of the respiratory system when they become charged.

Scientists believe the charge makes particles somewhere between 15 and 30 per cent more likely to remain in the lungs.  Continue reading…

Holiday units, rental homes and even car boots are being used as “pop-up” drug labs but what happens after they are shutdown?

Gold Coast Bulletin Jessica Elder 25 May 2015

THE Illicit Lab Investigation Team, a group of officers with chemistry training, is the first on scene when a drug lab has been uncovered.

MOST landlords won’t have their properties properly cleaned after a drug lab is shut down because they can’t afford the $40,000 bill, an expert has warned. Biohazard Trauma and Crime Scene Cleaning co-director Josh Marsden said it could take months to ensure no remnants of chemicals were left.

Cane farmers cutting the flow of chemicals to Great Barrier Reef Peter Michael, Brian Williams May 22, 2015

FARMERS say the run-off of reef-damaging fertiliser and pesticide has been slashed by at least 25 per cent over the past 50 years.
Third-generation Ingham cane farmer Jeffrey Cantamessa, 58, said he had seen a significant improvement since he was a boy.
Mr Cantamessa, who lives on the banks of the mighty Herbert River that empties into the inner Great Barrier Reef, said the state’s 4000 cane farmers in the $2 billion-a-year industry had largely been blamed for poor water quality and destruction of half the Reef over the past 30 years.

Toxic dust source targeted by new device at Townsville Port

Townsville Bulletin RACHEL AFFLICK  May 21, 2015

THE  State Government is commissioning a device to identify the sources of potentially toxic metals in dust from the Port of Townsville.
It comes as part of Government moves to step up its monitoring for toxic dust in the city after a study commissioned by the North Queensland Conservation Council (NQCC) found toxic dust in playgrounds at The Strand, Rowes Bay and Reid Park.
Environment Minister Steven Miles said in Townsville last week that a new instrument would soon be able to measure lead and other metals in dust in real time continuously.

The verdict’s in: we must better protect kids from toxic lead exposure

The Conversation | May 19, 2015 | Mark Patrick Taylor & Bruce Lanphear

The National Health and Medical Research Council (NHMRC) today released new guidelines aimed at reducing children’s harmful exposure to lead. Soil, dust, water and air-based exposure to lead can interfere with the development of the nervous systems and cause behavioural and developmental problems.  Continue reading…
