How Wood-Burning Stoves Threaten Health with Deadly Indoor Pollution

Recent research shows that wood-burning appliances and environmentally friendly stoves emit significant levels of harmful substances which can lead to severe health issues.

The popular household device is frequently utilized during colder seasons to help reduce energy costs.

Some believe that contemporary stoves equipped with innovative burning methods provide a more environmentally friendly and secure option.

However, specialists caution that it may impact indoor air quality, leading to possible significant health consequences.

They involve long-term breathing issues, cardiovascular problems, and pulmonary disorders. cancer and potentially harm to the kidneys, liver, brain, and nervous system.

This occurs due to their emission of contaminants like ultrafine particles (UFPs), fine particulate matter (PM2.5), black carbon (BC), and carbon monoxide.

It is estimated that 3.2 million Each year, people around the world pass away earlier than expected because of indoor air pollution caused by burning fuels incompletely—this includes 237,000 kids younger than five years old.

Scientists observed five residences in Guildford, Surrey, which utilized various types of heating stoves along with cleaner-burning solid fuels such as well-seasoned wood, kiln-dried wood, wooden briquettes, and non-smoking coal.

First place for the highest emissions was occupied by open fireplaces, which raised PM2.5 levels as much as sevenfold compared to contemporary stoves.

Next, in second position were multi-fuel eco-friendly stoves, which produce higher ultrafine particle emissions compared to conventional eco-designed models— which have high ratings for minimal pollution according to a British accreditation system.

In the meantime, wooden briquettes and smokeless coal raised ultrafine particle exposure by 1.7 and 1.5 times, respectively, when compared to modern stoves— challenging The belief that these artificial fuels are more environmentally friendly.

Although enhanced stoves decreased total pollutant emissions, the most effective models still led to substantial increases in indoor pollution when igniting, adding fuel, and removing ashes.

It is alarming that in numerous instances, the pollution levels surpassed those advised by the World Health Organization (WHO).

They also discovered that ventilation plays a key role, as homes with sealed windows during fires can experience pollution levels up to three times greater compared to those with windows opened.

A smaller room size combined with extended burn times was also linked to poorer indoor air quality.

The lead researcher of the study, Professor Prashant Kumar, stated: "As energy costs continue to increase, numerous families may start using solid fuels during the colder seasons, typically believing that contemporary stoves provide a more environmentally friendly and secure option."

Nevertheless, our research indicates that this change has an impact on indoor air quality, which could lead to significant health issues as individuals typically spend up to 90 percent of their time inside.

Health recommendations, guidelines for air circulation, and construction regulations need to evolve alongside shifting patterns of heating usage.

Abidemi Kuye, a PhD student affiliated with the GCARE, stated: "Despite using what are considered 'cleaner' stoves and fuel sources, we observed pollution levels increasing significantly above acceptable thresholds—particularly when air circulation was inadequate or the stoves were operated for extended durations."

Many individuals remain unaware of just how significantly indoor air quality can worsen with regular cooking activities.

This study highlights the importance of increased understanding and minor adjustments in behavior that may lower contact.

The group based at the University of Surrey's Global Center for Clean Air Research (GCARE) released their research in Nature's Scientific Reports.

Previously, experts had suggested The advantages of popular burners, including enhancing mental well-being and uniting family members, have been "neglected."

At the beginning of the year, a report stated that specialists from the Stove Industry Association (SIA), the UK's representative body for the sector, claimed that stoves and fireplaces contribute positively to both physical and psychological health.

The SIA did not dispute the health risks posed by pollutants released from stoves, but rather highlighted the advantages.

They argue that wood-burning stoves unite households and offer a more affordable and easier-to-use alternative to electrical heating systems.
