Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
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]
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.
Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death. A common response cascade to a variety of irritant gases includes inflammation , edema and epithelial sloughing , which if left untreated can result in scar formation ...
A 2017 SBU report found evidence that workplace exposure to silica dust, engine exhaust or welding fumes is associated with heart disease. [3] Associations exist for exposure to arsenic, benzopyrenes, lead, dynamite, carbon disulfide, carbon monoxide, metalworking fluids and occupational exposure to tobacco smoke. [3]
Suicide by carbon monoxide poisoning may be attempted by running the engine in an enclosed garage, or by piping the exhaust gas into the driver's compartment with a hose, but catalytic converters required for air quality regulations eliminate over 99% of carbon monoxide produced. [1]
I got a fever — and the only prescription is Saturday Night Live documentary footage.. SNL alums reflect on Will Ferrell's comedic electricity in the iconic "More Cowbell" sketch in an exclusive ...
Humans can smell chlorine gas at ranges from 0.1–0.3 ppm. According to a review from 2010: "At 1–3 ppm, there is mild mucous membrane irritation that can usually be tolerated for about an hour. At 5–15 ppm, there is moderate mucous membrane irritation. At 30 ppm and beyond, there is immediate chest pain, shortness of breath, and cough.
