Has
Peruvian Meteorite Brought New Disease To Earth?
by
RIA Novosti
The
recent fall of the meteorite in the district of Desaguadero in Puno, Peru, has
already evoked many rumors and speculations.
Eyewitnesses
have reported that the enflamed ball collided with the Earth and went inside to
the depth of six meters, leaving a crater of about 30 meters with a gushing fountain
of boiling water. After some time people felt an acrid smell and began to suffer
from nausea and headaches.
A
representative from the Peruvian Health Ministry hastened to blame this on poisonous
fumes from fragments of meteorites, which contain cyanide.
Dr.
Mikhail Nazarov, head of the meteoritics laboratory ay the Vernadsky Institute
of Geo- and Analytical Chemistry, said that the reports from Peru describe phenomena
typical for meteorites. But he pointed out that reports of the meteorite-linked
"strange disease" sounded dubious: "In the past 250 years, 102
large meteorites have been registered; 70 of these have been found and 50 are
kept in the Meteorite Collection of the Russian Academy of Sciences. But none
have had any adverse effect on human health."
No
consequences were produced even by the unique Sikhote-Alin Fall (February 12,
1947), when a whole stream of meteorites with a general mass of up to a hundred
tons crushed the Ussuri taiga in the Far East, covering a territory of 35 square
km.
There
is no information about any meteorite-related negative influence on human health.
All in all, there are about a thousand registered meteorites.
"To
the knowledge of scientists, the meteorite substance is harmless and sterile compared
with the earth. No microbes, bacteria or extra-terrestrial viruses have been found
on meteorites. As for radioactivity, it is much stronger in granite," Nazarov
said.
This
is how he explained the events in Peru: "A powerful shock from the meteorite
could have caused cracks in the ground and upset the ground water circulation.
As a result, dirty waters from rivers and wells with poisonous gases could come
into play." He said it's highly unlikely for a meteorite to smell like lead
or silver. These substances exist in meteorites in negligible amounts, if at all.
For the most part, meteorites are formed of iron sulfides. It has been observed
that fallen meteorites emit a sulfur smell, but it wouldn't poison anyone.
In
Peru, the meteorite might have "targeted" iron ore deposits, which emitted
their fumes. But the scientist is convinced that this is a local and temporary
effect.
