A recent study has revealed that gas stoves emit harmful particles that are linked to asthma in children.

A recent report has revealed that gas stoves are emitting harmful particles that have been linked to childhood asthma, contaminating kitchens, living rooms, and bedrooms throughout Europe.


Researchers from the Netherlands conducted a study on the air pollution in 247 households and determined the average concentration of nitrogen dioxide (NO2).2

The levels of pollution in households using gas cookers were nearly double that of households using electric cookers. A quarter of the gas-using homes exceeded the hourly pollution standards set by the World Health Organization, while none of the homes using electric cookers surpassed the limits.

Piet Jacobs, a researcher from the Netherlands Organisation for Applied Scientific Research, stated that switching to electric cooking and using properly designed ventilation hoods can decrease exposure to harmful particulate matter from cooking to below recommended levels.


Using gas for cooking emits NO2 into the environment.2 that hurt lungs and inflame airways. Scientists have long known of an association between gas cookers and childhood asthma, though they have not proved a causal link between the two.

The report, which was commissioned by the energy efficiency group Clasp, measured indoor NO2

The researchers selected residences in seven European nations where individuals did not smoke and were located far from heavily trafficked areas and industrial sites to minimize the impact of other pollutants.

2 pollution is 40 micrograms per cubic meter

Researchers discovered that pollution levels would increase significantly and remain high for a few hours after cooking, with the intensity of the pollution increasing as cooking time increased. The World Health Organization recommends a daily limit of 40 micrograms per cubic meter for NO2 pollution.2

There were 3.25 days during the 13-day testing period when pollution levels exceeded the limit.

“This is a key study that will facilitate raising awareness and triggering action that will protect the health of those most vulnerable, like our children,” said Juana María Delgado-Saborit, the head of the environmental health research lab at Jaume I University in Spain, who served as an external reviewer for the study.

She stated that the main drawback of the research was the use of sensors, which were not as accurate as the advanced scientific equipment typically used in indoor or outdoor air quality measurements. To address this issue, the sensors were calibrated both before and after being installed in every household.

“Delgado-Saborit expressed confidence in the researchers’ methods, citing the evidence from their quality assurance program.”

The research discovered that using gas for cooking often resulted in high levels of indoor air pollution that would be considered unlawful if found outdoors. Although the World Health Organization’s standards for clean air apply to both indoor and outdoor environments, the regulations in the EU and UK only pertain to outdoor pollution levels.

The report suggests that governments should enhance regulations surrounding cooking devices, companies should cease producing and installing gas stoves and ovens, and consumers should switch to electric cookers and properly ventilate their kitchens using cooker hoods and open windows.
