Hi Darren,

we have a member in the German meteorite forum, living in Peru, who visited
the fall site.

He wrote, that the reports about the "illness" and "desease" are enormously
exaggerated by the media and almost a lie.

The crater is filled with groundwater, usually found in 3-4 meter depth.
No smokes, no gases, no sulphuric smell - only that the water smells a
little bit moldy, which was stronger some days ago.

He saw the locals are alive and kicking, nobody got ill.
That was also reported by his driver, living in that aerea.
Only a few got a little headache from the smell,
among them a single police man, and police also told that no illnesses or
more hefty symptoms than a few single cases of a little headache were
observed.
Nor got anyone severely ill.

So all a hoax by media.

Best!
Martin

Meteor Crash in Peru Caused Mysterious Illness

An object that struck the high plains of Peru on Saturday, causing a
mysterious
illness among local residents, was a rare kind of meteorite, scientists
announced today.

A team of Peruvian researchers confirmed the origins of the object, which
crashed near Lake Titicaca, after taking samples to a lab in the capital
city of
Lima (see Peru map).


Nearby residents who visited the impact crater complained of headaches and
nausea, spurring speculation that the explosion was a subterranean geyser
eruption or a release of noxious gas from decayed matter underground.

But the illness was the result of inhaling arsenic fumes, according to Luisa
Macedo, a researcher for Peru's Mining, Metallurgy, and Geology Institute
(INGEMMET), who visited the crash site.

The meteorite created the gases when the object's hot surface met an
underground
water supply tainted with arsenic, the scientists said.

Numerous arsenic deposits have been found in the subsoils of southern Peru,
explained Modesto Montoya, a nuclear physicist who collaborated with the
team.
The naturally formed deposits contaminate local drinking water.

"If the meteorite arrives incandescent and at a high temperature because of
friction in the atmosphere, hitting water can create a column of steam,"
added
Jos? Ishitsuka, an astronomer at the Peruvian Geophysics Institute, who
analyzed
the object.

By Wednesday, according to Macedo, all 30 residents who felt ill reported
feeling better.

"People Were Extremely Scared"

Locals described the meteorite as a bright, fiery ball with a smoke trail.
The
sound and smell rattled residents to the point that they feared for their
lives,
Ishitsuka said.

The meteorite's impact sent debris flying up to 820 feet (250 meters) away,
with
some material landing on the roof of the nearest home 390 feet (120 meters)
from
the crater, Ishitsuka reported.

"Imagine the magnitude of the impact," he said. "People were extremely
scared.
It was a psychological thing."

The meteorite's crash also caused minor tremors, shaking locals physically
and
emotionally.

"They were in the epicenter of a small earthquake," Montoya, the nuclear
physicist, said.

The resulting crater resembles a muddy pond measuring 42 feet (13 meters)
wide
and 10 feet (3 meters) deep.

Solving the Mystery

Even as meteorite samples arrived in Lima Thursday for testing, Peruvian
scientists seemed to unanimously agree that it was a meteorite that had
struck
their territory.

"Based on the first-hand reports, the impact and the samples, this is a
meteorite," Macedo, of INGEMMET, said.

Tests revealed no unusual radiation at the site, though its absence didn't
rule
out a meteorite crash.

"Everything has radioactivity, even underground rocks," Montoya said. "But
nothing out of the ordinary was found."

Preliminary analysis by Macedo's institute revealed no metal fragments,
indicating a rare rock meteorite. Metal stands up better to the heat created
as
objects enter Earth's atmosphere, which is why most meteorites are metallic.

The samples she reviewed had smooth, eroded edges, Macedo added.

"As the rock enters the atmosphere, it gets smoothed out," she said.

The samples also had a significant amount of magnetic material
"characteristic
of meteorites," she said.

"The samples stick to the magnet," Ishitsuka, the astronomer, confirmed.
"That
shows that there is iron present."

Water samples at the crater proved normal, but the color and composition of
soil
were "unusual" for the area, Macedo noted.

Jos? Machare, a geoscience adviser at INGEMMET, said x-ray tests conducted
on
the samples earlier today further confirmed the object's celestial origins.

He said the group's findings put to rest earlier theories that the object
was a
piece of space junk or that the crater had formed by an underground
explosion.

"It's a rocky fragment," Machare said, "and rocks that fall from the sky can
only be meteorites."
