Who, What, Why: Is it safer to cook rice in a coffee percolator to avoid arsenic?

BBC News Magazine 23 July 2015

Researchers at Queen’s University Belfast found that preparing rice in coffee filter machines can reduce harmful amounts of arsenic which can cause bladder and lung cancer as well as damage to the nervous system. This is particularly an issue with babies and small children, whose exposure is greater.

Concerted clean up of lead contamination at Broken Hill and Esperance contrast with other regional towns

ABC News | ABC Rural  Sarina Locke 20 July 2015

Lead contamination remains a big issue for many regional towns, but there is no nationally consistent approach on how to deal with it.

New stricter national health guidelines mean that even in towns where there have been successful campaigns to reduce residents’ exposure to lead, very young children still have worrying lead levels in their blood.

Clean-up efforts are sporadic and often the lead dust issue is swept under the carpet.

SciFinder Access at FSS

Staff at FSS now have unlimited access to SciFinder (Chemical Abstracts Service) on the web.  This means we can perform an unlimited number of searches as well as concurrent searches (ie more than one person can be logged on at any one time).  Individual logins are still required however.

SciFinder is a research discovery application that provides unlimited access to the world’s most comprehensive and authoritative source of references, substances and reactions in chemistry and related sciences.

It includes a broad spectrum of technical and scientific information based on the CAplus, CASREACT, and Registry databases from the Chemical Abstracts Service. It indexes journals, books, conferences, patents, dissertations – in chemistry, biochemistry, physical, inorganic, analytical chemistry, applied chemistry, chemical engineering, macromolecular chemistry and organic chemistry. And it is updated daily.

SciFinder allows you to search by keyword or topic as well as by molecular formula, substance identifier eg CAS Registry Number, and chemical or reaction structure.

Training or product demonstrations are available.

Collapse at Clarence Colliery at Lithgow ‘equivalent to giant oil spill’, wilderness foundation says

ABC News 3 July 2015

Conservationists believe the collapse of a dividing wall at a coal mine in Lithgow is “equivalent to a giant oil spill”.

The NSW Environmental Protection Authority (EPA) began investigating the incident yesterday and said at least 150 metres of the Wollangambe River was “showing signs of impact”.

The cause for the collapse at the Clarence Colliery is still unknown, as is the overall damage that might be done to the Greater Blue Mountains World Heritage Area, the boundary of which is within two kilometres of the mine.

Fetuses more vulnerable to some environmental contaminants penetrating into cord blood

(Pohang University of Science & Technology (POSTECH) 25 June 2015) A new research featured in the Environmental Science and Technology published by the American Chemical Society suggests that the fetus is more vulnerable to some pollutants with certain properties because they penetrate further into the feto-maternal system. The research found that distributions of pollutants and the mechanisms of distributions vary depending on each pollutant’s physicochemical characteristics.

Conservation council welcomes monitoring of lead dust

Townsville Bulletin TONY RAGGATT  June 12, 2015

IT is hoped new monitoring will identify why elevated levels of heavy metals in dust have been found at sites around Townsville, including in children’s playgrounds.
So far, researchers have pointed to the Port of Townsville and the presence of Mount Isa types of ore in dust.
North Queensland Conservation Council co-ordinator Wendy Tubman yesterday welcomed extra monitoring and the formation of a Townsville Port Stakeholders Working Group to “get to the bottom of this”.
Ms Tubman said the presence of the heavy metals was “cause for concern”.
