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 ...
Acid rain has a much less harmful effect on oceans on a global scale, but it creates an amplified impact in the shallower waters of coastal waters. [95] Acid rain can cause the ocean's pH to fall, known as ocean acidification , making it more difficult for different coastal species to create their exoskeletons that they need to survive.
Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). 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 ...
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 ...
It is generated on site by reacting potassium cyanide or sodium cyanide with sulfuric acid (e.g., in a modern American gas chamber). Fumes arise during a building fire or any similar scenario involving the burning of polyurethane, [21] vinyl [22] or other polymer products that required nitriles in their production.
Smog, or smoke fog, is a type of intense air pollution.The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog [1] to refer to smoky fog due to its opacity, and odor. [2]
The sulfuric acid dissolves the carbonates in the hardened cement paste (HCP), and also calcium hydroxide (portlandite: Ca(OH) 2) and calcium silicate hydrate (CaO·SiO 2 ·nH 2 O), and causes strength loss, as well as producing sulfates which are harmful to concrete. [19] H 2 SO 4 + Ca(OH) 2 → CaSO 4 + 2 H 2 O H 2 SO 4 + CaO·SiO 2 ·n H 2 O ...
The impact on wildlife stems primarily from disturbing, removing and redistributing the land surface. Some impacts are short-term and confined to the mine site however others have far-reaching, long-term effects. The most direct effect on wildlife is destruction or displacement of species in areas of excavation and spoil piling.
