Smoke inhalation is the breathing in of harmful fumes (produced as by-products of combusting substances) through the respiratory tract. [1] This can cause smoke inhalation injury (subtype of acute inhalation injury) which is damage to the respiratory tract caused by chemical and/or heat exposure, as well as possible systemic toxicity after smoke inhalation.
Idling automobiles with the exhaust pipe blocked by snow has led to the poisoning of car occupants. [83] Any perforation between the exhaust manifold and shroud can result in exhaust gases reaching the cabin. Generators and propulsion engines on boats, notably houseboats, have resulted in fatal carbon monoxide exposures. [84] [85]
A lot of the time they test you for CO2, which can be an indication of exposure,” he said. “What we would like to do is to develop a test that would prove that you have been exposed.”
HNO 3, nitric acid, is a sticky compound that can easily be removed onto surfaces (dry deposition) or dissolved in water and be rained out (wet deposition). Both ways are common in the atmosphere and can efficiently remove radicals and nitrogen dioxide. The presence of smog in California is shown near the Golden Gate Bridge.
Air pollution can cause diseases, allergies, and even death; it can also cause harm to animals and crops and damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). [3] Air pollution can occur naturally or be caused by human activities. [4]
She had a chemical engineering background. [5] She was suffering from an economic depression at the time, and suicide in general was increasing. After the details of this suicide were highly publicised by local media, many others killed themselves in this way (an example of the Werther effect).
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
This is the simplest and probably the most accurate method, but can only be used where the smoke concentration is slight, as the filter can quickly become blocked. [ 65 ] The ASTM smoke pump is a simple and widely used method of in-line capture where a measured volume of smoke is pulled through a filter paper and the dark spot so formed is ...
