What is the most harmful type of gas?
The most toxic gas in the universe is hydrogen cyanide. It is a highly toxic and flammable chemical compound that consists of a hydrogen atom, a carbon atom, and a nitrogen atom. It can be found in space, as well as on Earth in certain industrial processes and natural sources.
Examples include carbon dioxide, nitrogen, aliphatic hydrocarbon gases (butane, ethane, methane, and propane), and noble gases (argon, helium, neon, radon, and xenon).
Option A: CO or carbon monoxide is considered to be the most toxic gas as it shows high affinity to haemoglobin. Carbon monoxide combines with haemoglobin to form carboxyhemoglobin that causes trouble in breathing and can lead to death by suffocation. Therefore, this option is correct.
Toxic gases are gases with hazardous physiological effects when inhaled.
Prolonged exposure to above-normal oxygen partial pressures, or shorter exposures to very high partial pressures, can cause oxidative damage to cell membranes, collapse of the alveoli in the lungs, retinal detachment, and seizures. Oxygen toxicity is managed by reducing the exposure to increased oxygen levels.

Botulinum toxins, exotoxins of Clostridium botulinum, are the most toxic naturally occurring substances known to man.
A. Some, but not all, gases are harmful to humans.
The predominant toxic gas is carbon monoxide, which is readily generated from the combusion of wood and other cellulosic materials.
Chlorine trifluoride is the most flammable gas
By all scientific accounts, chlorine trifluoride has been proven to be the most flammable of all the chemical gases. It's deceptively colourless, extremely reactive, and capable of burning through concrete and gravel.
Which gas is most harmful to ozone?
Chlorofluorocarbons. Chlorofluorocarbons (CFCs) were widely used as refrigerants until the 1980s when it was confirmed that they were the main source of harm to the ozone layer. They are also considered greenhouse gases that cause climate change.
Some of the most prevalent explosive gases used in manufacturing are Hydrogen, Oxygen, Methane, and Acetylene.
Why is hydrogen sulfide so deadly? It is highly flammable and toxic, even at low concentrations. It is heavier than air and may travel along the ground.
Methane is non-toxic and creates no hazard when inhaled in limited quantities; however, if large quantities of natural gas or methane is allowed to displace air, lack of oxygen may result in suffocation.
Natural gas withdrawn from natural gas or crude oil wells is called wet natural gas because, along with methane, it usually contains NGLs—ethane, propane, butanes, and pentanes—and water vapor.
Extended exposure to above-normal oxygen partial pressures or shorter exposures to very high partial pressures can cause oxidative damage to cell membranes leading to the collapse of the alveoli in the lungs. Pulmonary effects can present as early as within 24 hours of breathing pure oxygen.
In hospital settings, 100% oxygen may be delivered -- but even then only on a short-term basis, says Boyer -- less than 24 hours and preferably less than 12 hours. To breathe pure oxygen at that level for any longer can have toxic results, including "shock lung," or adult respiratory distress syndrome.
Notable examples of asphyxiant gases are methane, nitrogen, argon, helium, butane and propane. Along with trace gases such as carbon dioxide and ozone, these compose 79% of Earth's atmosphere.
Carbon monoxide (CO), known as the Invisible Killer, is a colorless, odorless, poisonous gas that results from incomplete burning of fuels such as natural gas, propane, oil, wood, coal, and gasoline.

Which gas is very harmful for environment?
Major greenhouse gases include carbon dioxide, methane, nitrous oxide, and various synthetic chemicals. Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.
1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known.
A substance is considered extremely toxic if it has an LD50 of less than 5 mgs/kg of animal body weight. To humans, this is the equivalent of a taste (less than 7 drops). It is Highly toxic if it has an LD50 of between 5 and 50 mg/kg of animal body weight to a human, this would be about a teaspoon.
Ammonia is the most toxic form of waste that needs to be excreted.
Hydrogen is not toxic but is a simple asphyxiate by the displacement of oxygen in the air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Hydrogen is used to make other chemicals and in oxyhydrogen welding and cutting. ODOURLESS COLOURLESS COMPRESSED GAS.
