For superficial injuries, washing (therapeutic irrigation) is important.Emergency treatments include protecting the airway, which might involve a tracheostomy.Further treatment will vary depending on the severity, but might include investigations to determine the extent of damage (bronchoscopy for the airways and endoscopy for the gastrointestinal tract), followed by treatments including ...
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H 2 SO 4. It is a colorless, odorless, and viscous liquid that is miscible with water. [7] Structure ...
The hydrogen sulfide gas is biochemically oxidized in the presence of moisture to form sulfuric acid. The effect of sulfuric acid on concrete and steel surfaces exposed to severe wastewater environments can be devastating. [1] In the USA alone, corrosion causes sewer asset losses estimated at $14 billion per year. [2]
Vog is created when volcanic gases (primarily oxides of sulfur) react with sunlight, oxygen and moisture.The result includes sulfuric acid and other sulfates. [4] Vog is made up of a mixture of gases and aerosols which makes it hard to study and potentially more dangerous than either on their own.
These effects are believed to be due to hydrogen sulfide combining with alkali present in moist surface tissues to form sodium sulfide, a caustic. [66] These symptoms usually subside in a few weeks. Long-term, low-level exposure may result in fatigue , loss of appetite, headaches , irritability, poor memory, and dizziness .
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.
Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere. There are severe health effects caused by burning coal. [2] [3] [4] Worldwide 25 people die early for each terawatt hour of electricity generated by coal, around a thousand times more than nuclear or solar. [5]
Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
