Scientist have found that when oxygen staved cells are rapidly delivered very high levels of oxygen it can kill them.
People suffering from severe lung/respiratory impairment can be harmed by even small increases in oxygen concentration (i.e. >21% oxygen that we normally breath in the air).
The bluish poisonous gas which is a type of allotrope of oxygen is named "ozone".
oxygen
Breathing 100% of it... No oxygen...
Carbon monoxide is poisonous because it binds to hemoglobin in the blood much more tightly than oxygen, preventing oxygen from being carried to the body's tissues. This can lead to tissue damage and eventually death due to lack of oxygen.
The evolution of photosynthetic bacteria and later on, plants, was responsible for changing the formerly poisonous atmosphere to an oxygen-rich one we have today. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing levels of oxygen in the atmosphere.
An unstable and poisonous allotrope of oxygen. It's formula is O3.
It's only poisonous when a single oxygen atom is bonded with a single carbon atom. This makes carbon monoxide, and is poisonous to the body, because the body can't use it. We take in the natural occurring form of oxygen as 02, meaning that there are two oxygen atoms bonded together. We use this form of oxygen to carry out our life processes. When the person is exposed to carbon monoxide and oxgygen (O2), the body chooses carbon monoxide unaware that the body is unable to use it. So in conclusion, carbon monoxide is poisonous, but oxygen in the form of O2, is what we need to survive, so it's not poisonous.
Carbon monoxide is the poisonous gas that interferes with the blood's ability to carry oxygen. It binds with hemoglobin in the blood, reducing the amount of oxygen that can be transported to the body's tissues and organs.
Inhaling pure oxygen can be harmful in high concentrations as it can lead to oxygen toxicity. However, oxygen is essential for living organisms to survive and is not considered poisonous in normal atmospheric levels.
No. But breathing pure xenon will block oxygen and cause asphyxiation.
Hydrogen gas itself is not poisonous, as it is a naturally occurring element and is non-toxic. However, hydrogen can be dangerous if it is in high concentrations in the air because it is highly flammable and can displace oxygen, leading to a potential risk of asphyxiation.
Early photosynthetic bacteria, such as cyanobacteria, were responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere through the process of photosynthesis. These organisms released oxygen as a byproduct of converting sunlight into energy, which gradually increased the atmospheric oxygen levels over time.
