Inhaling 'Red Mud Disaster' dust may not be as harmful to health as feared

17.02.2011
Scientists in Hungary are reporting that the potential health effects of last October's Red Mud Disaster, one of the worst environmental accidents in Europe, may be less dangerous than previously feared.

Their study, reported in ACS's journal Environmental Science & Technology, concludes that the dust from the mud may be no more harmful than particles of ordinary urban air pollution.

Mihály Pósfai and colleagues point out that a burst dam at a factory that processes aluminum ore last October inundated areas near Ajka in northern Hungary with more than 700,000 cubic yards of caustic red mud. Ten people died and dozens were injured. Since the mud contained potentially toxic substances, concern arose about the health effects of inhaling dust formed when the mud dried and was swept into the air by wind.

They studied the chemical and physical properties of the red mud particles and dust and concluded that particles of red mud dust were too large to be inhaled deeply into lungs, where they could cause the most damage. Although the resuspension potential of red mud dust is large, inhalation likely would cause irritation and coughing, but would not increase the risk of other more serious health problems, the report suggested.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
