Is natural gas barbecue toxic?

Natural gas is now gradually becoming popular, and many communities have already begun using it. Some friends want to use natural gas for barbecue, but this way of barbecue is actually not advisable, because using natural gas for barbecue will produce some toxic substances remaining on the food.

1. Is natural gas barbecue toxic?

Grilling food directly with natural gas can be toxic. It is very easy to get carbon monoxide poisoning if you use natural gas to grill. Some harmful substances will be adsorbed onto the food, such as sulfide, not to mention that the food grilled in this way will not taste good.

2. Hazards of Natural Gas

1. Inhalation of high concentrations can cause death

Natural gas can suffocate people when the content in the air reaches a certain level. Natural gas is not as toxic as carbon monoxide and is essentially harmless to humans. However, if natural gas is in a high concentration and the oxygen in the air is insufficient to sustain life, it can still cause death, after all, natural gas cannot be used for human breathing.

2. The explosion is powerful

As a fuel, natural gas can also cause casualties due to explosions. Although natural gas is lighter than air and easier to disperse, when it gathers in a closed environment such as a house or tent and reaches a certain proportion, it will trigger a powerful explosion. The explosion could flatten an entire house and even damage neighboring buildings. The lower explosion limit of methane in air is 5% and the upper explosion limit is 15%. The explosion of compressed natural gas used in natural gas vehicle engines is basically not possible under spontaneous conditions due to the volatile nature of the gas, so external force is needed to maintain the natural gas concentration between 5% and 15% to trigger the explosion.

The harm of toxic barbecue to human body

If people like to eat barbecued food contaminated by benzopyrene, the carcinogen will accumulate in the body, and there is a risk of inducing stomach cancer and intestinal cancer. At the same time, barbecued food also contains another carcinogen - nitrosamines. The marinating process before grilling skewers is prone to produce nitrosamines.
