Controversy over the analysis of volcanic ash
Denies that are safe for health
Friday June 17, 2011 | Posted in print
What kind of ore have fallen on Argentine cities? Are substances that make up the ash is harmful to health? With these two premises as a starting point, researchers at the National Atomic Energy Commission (CNEA), Bariloche, conducted a chemical study of the ashes of the Puyehue-Cord?n volcanic complex Caulle, remaining in the two cities closest to Argentine volcano, Bariloche and Villa La Angostura.
Preliminary results of this work, the CNEA released a statement last Monday revealed no substances harmful to health, as may be sulfur or arsenic, and the message was spread peace to the people of the region.
However, yesterday, the Foundation for Environmental Defense (Funam) and the NGO Solidarity Consciousness reported that the press release issued by the CNEA "is inaccurate" and that public disclosure of that volcanic ash is not harmful to health "is incorrect and irresponsible. "
"The ash is composed of silicon, aluminum, potassium, calcium, iron, titanium, magnesium, sodium, and a small amount, chloro-Mogni explained Dr. Liliana, member of the Materials Characterization Group of the CNEA. There was no the presence of sulfur or arsenic, nor cristobalite (a variant volcanic quartz), as did the Chait?n volcano in 2008, is one of the most harmful fractions that cause lung and breathing problems. "
"Who will take care of the diseases that produce this irresponsible statement? Is not to create panic, but do not provide wrong information," said another statement by the NGO Solidarity Consciousness.
It happens that, according to data from the CNEA, Puyehue volcano ashes contain titanium dioxide, "a substance considered a possible human carcinogen by the International Agency for Research on Cancer (IARC)," said Funam.
For his part, Dr. Raul Montenegro, National University of Cordoba, said that volcanic ash "can have negative health effects" and that impact should be "not only to hazardous substances, such as crystalline silica and carbon Titanium-but the particle size and the amount that enters the respiratory and digestive systems of those exposed. "
The specialist also said that the ashes "make cocktails variables of particles and chemicals," and that the effects on exposed populations "depend on the dose received, but also the exposure time and the size of people. The most affected are infants and children, because they use proportionally more air per pound than adults, and people with respiratory problems earlier. "
Solidarity and Awareness Funam advised "reduce inhalation of ash as far as possible as a health measure," using masks.
