Are gas cookers dangerous?
Thanks for asking. Gas cookers are a common feature in many kitchens, often preferred by chefs and home cooks for their precise temperature control.
But gas cookers emit a number of harmful substances when they're in use and even when they're off.
What are some of the pollutants and their effects?
Nitrogen oxide or NO2 is a gas that is produced when natural gas is burned at high temperatures.
It can damage your airways and worsen asthma.
A recent report by the Dutch Lung Foundation found that gas cookers increased the risk of asthma in children by 42%.
Carbon monoxide or CO is a colourless and odourless gas that is produced by incomplete combustion of natural gas.
It can reduce the oxygen supply to your organs and tissues and causes symptoms such as headaches, dizziness, nausea and fatigue.
In high concentrations it can be deadly.
A study by the US Environmental Protection Agency found that gas stoves contribute to up to 30 % of the CO exposure in our homes.
Particulate matter or PM is a mixture of tiny solid and liquid particles that are suspended in the air.
Some of these particles are so small that they can enter your lungs and bloodstream.
They can cause inflammation, infection and disease of the respiratory and cardiovascular systems.
A study by the University of Sheffield found that gas cookers emit up to 10 times more PM than electric cookers.
Formaldehyde or HCHO is a volatile organic compound that is emitted by gas cookers.
It's a known human carcinogen and can cause eye, nose and throat irritation.
A study by the Lawrence Berkeley National Laboratory found that gas cookers emitted five times more formaldehyde than the levels recommended by the US National Institute for Occupational Safety and Health.
Benzene or C6H6 is another volatile compound emitted by gas cookers, even when they're off.
It's also a known human carcinogen.
A study by PSE Health Energy found that gas cookers emitted as much benzene as a cigarette smoker does and that benzene was detected in 99 % of the samples taken in homes in California.
So what can you do to reduce these risks?
One option is switch to electric or induction cookers which do not produce any combustion by -products.
Another option is to use a range hood or an exhaust fan that can vent the pollutants outside.
A third option is to open the windows and doors to increase the ventilation and dilute the concentration of the pollutants.
And finally, you can also use a carbon monoxide detector and an air purifier to monitor and improve the indoor air quality.
There you have it. Now you know if gas cookers are dangerous.
