Question

some points of disadvantage of oxygen ​

Answer 1

$\huge\colorbox{red}{Answer}$

Prolonged exposure to above-normal oxygen partial pressures, or shorter exposures to very high partial pressures, can cause oxidative damage to cell membranes, collapse of the alveoli in the lungs, retinal detachment, and seizures. Oxygen toxicity is managed by reducing the exposure to increased oxygen levels

Answer 2

Oxygen is an important gas but it has some disadvantages as well

It is highly combustible so can wreak havoc during fire accidents .

Toxicity of oxygen is also harmful.

It binds to RuBisCo enzyme and leads the process of photorespiration instead of photosynthesis in plants like Sunflower, Eucalyptus etc.
