Hydrogen sulfide is also a potent cellular toxin, blocking the cytochrome system and inhibiting cellular respiration. More water-soluble gases (e.g. chlorine, ammonia, sulfur dioxide, hydrogen chloride) dissolve in the upper airway and immediately cause mucous membrane irritation, which may alert people to the need to escape the exposure.
Effects depend on the substance; hydrogen peroxide removes a bleached layer of skin, while nitric acid causes a characteristic color change to yellow in the skin, and silver nitrate produces noticeable black stains. Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion.
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
It may cause injury to the respiratory epithelial cell after its attachment. The injury of host epithelial cells caused by M. pneumoniae adhesion is thought to be due to the production of highly reactive species: hydrogen peroxide (H 2 O 2) and superoxide radicals (O 2 –). [11] M. pneumoniae has the potential for intracellular localization.
Oxidative stress from oxidative metabolism causes base damage, as well as strand breaks in DNA. Base damage is mostly indirect and caused by the reactive oxygen species generated, e.g., O − 2 (superoxide radical), OH (hydroxyl radical) and H 2 O 2 (hydrogen peroxide). [2] Further, some reactive oxidative species act as cellular messengers in ...
A hundred times smaller than a grain of sand, silica dust can lead to lung cancer and silicosis, an irreversible scarring and stiffening of the lungs, among other conditions, according to the ...
Pulmonary fibrosis creates scar tissue. The scarring is permanent once it has developed. [29] Slowing the progression and prevention depends on the underlying cause: Treatment options for idiopathic pulmonary fibrosis are very limited, since no current treatment has stopped the progression of the disease.
While hydrogen peroxide does have known antiseptic properties, it may do more harm than good when it comes to wound care. Everyone puts hydrogen peroxide on their wounds. They really shouldn't.
