Hydrazine and the Upper Atmoshpere

A malfunctioning satellite was hit by a missile and most likely the fuel
tank containing 1000 kg (or what it 1000 lbs?) of hydrazine was
punctured. Thus a large amount of hydrazine, a dangerous reactive
chemical, was released into the upper atmosphere. What is the impact of
dumping this toxin into the atmosphere?

How stable is this chemical?

Will it remain intact eventually being inhaled or ingested?

Will it react with oxygen and water vapor reducing it
to harmless compounds or less toxic compounds?

Will it react with ozone, destroying amounts of ozone?

Just what will it do? Please, reply only if you actually know the
chemical properties of hydrazine.

"By all accounts this was a successful mission. From the debris analysis, we
have a high degree of confidence the satellite's fuel tank was destroyed and
the hydrazine has been dissipated," said Gen. James E. Cartwright, vice
chairman of the Joint Chiefs of Staff.

"The successful satellite engagement was truly a collaborative effort from
across the U.S. government, the armed forces, industry and academia working
together to reduce the risk to human life, said Cartwright.

A single modified tactical Standard Missile-3 (SM-3), fired from the USS
Lake Erie was used to engage the satellite. The remaining two modified
missiles will be configured back to their original status as tactical
missiles and the operational computer software programs aboard the Aegis
ships will be re-installed.

The Joint Functional Component Command for Space Joint Space Operations
Center at Vandenberg Air Force Base, Calif., is tracking less than 3,000
pieces of debris, all smaller than a football. The vast majority of debris
has already reentered or will shortly reenter the Earth's atmosphere in the
coming days and weeks. To date, there have been no reports of debris landing
on Earth and it is unlikely any will remain intact to impact the ground.

U.S. Strategic Command space surveillance sensors continue to track and
characterize the debris to ensure timely notifications are made, if
necessary, with regards to ground or on-orbit debris-related risk.
