What acute chemical pollutants are released by solid rocket boosters using ammonium perchlorate composite propellant (APCP)?
Answer
Hydrochloric acid ($ ext{HCl}$), chlorine gas, and aluminum oxide particles
The exhaust from solid propellants like APCP releases hydrochloric acid ($ ext{HCl}$), chlorine gas, and aluminum oxide particles, which are chemically active pollutants.
