New Report Shows Wood Furnaces Pose a Threat to Community Health

This week Environment and Human Heath Inc. (EHHI) published the first peer-reviewed article focused on the dangers of wood smoke emissions and wood burning devices. And the results were conclusive: wood smoke is a serious threat to public health. Wood smoke contributes to air pollution which can cause asthma, affect lung function, and cause cardiac arrhythmias and acute heart attacks.

“Wood smoke particles are particularly dangerous because they are small and thus are inhaled deeply into the lungs. The wood smoke particles contain many of the same harmful compounds found in cigarette smoke, and they are carcinogenic”

– Nancy Alderman, President of Environment and Human Health, Inc.

Wood smoke from outdoor wood-fired boilers (OWB), wood stoves and open burning, all contribute to air pollution. But it is the outdoor wood-fired boilers or wood furnaces that are the most harmful. It is estimated that an average OWB produces as many fine particulates per hour as 22 indoor wood stoves.

This study showed that homes neighboring an OWB unit had “significantly higher particulate levels than control houses that were not near an OWB”. Homes nearly three football fields away (850 ft.) from an OWB unit had six times the level of particulates as control homes. That is four times the EPA’s air standard level.  And homes 240 feet away from an OWB had particulate level twelve times the levels of control homes, eight times the EPA air standard level.

This is troubling. Neighbors of those who use OWBs are exposed to an extremely high level of particulate matter with no way to move their homes to safety. Most states have no setback regulations but, for the few states that do, this study shows that they are not strong enough. Connecticut, for example, has a 200 ft. setback requirement, which would still put neighbors well within the danger zone of exceptionally high level of particulate matter pollution.

Dr. David Brown, public health toxicologist with EHHI said it best when he said, “Outdoor wood furnaces should be labeled with cancer and asthma warnings.” Current setback regulations do not protect public health. This means that we need to adopt stricter regulations and cleaner technologies to make sure that our neighbors have clean, safe air to breathe.

  1. Outdoor Wood Furnaces need to be banned or the gains made in public health will be lost. I note the emphasis on the gains made to date but there still remains the huge impact on human health as a result of urban wood burning.
