Study of samples from seven winters suggests neurotoxic metal coming from wood itself rather than old paint

Wood heating is reintroducing lead into the air of local communities and homes, a systematic investigation by academics has found.

Overwhelming evidence of lead’s neurotoxicity meant the metal was banned as an additive in petrol more than 25 years ago. The research by academics from the University of Massachusetts Amherst began by analysing samples of particle pollution from five suburban and rural towns in the north-east US. They looked for tiny particles of potassium that are given off when wood is burned and also particles containing lead.

Samples from seven winters revealed associations between potassium and lead. When there were more wood burning particles in a daily sample, there was more lead in the air, with clear straight-line relationships in four of the five towns.

…

The project was extended to 22 other towns across the US. The relationships between lead and potassium varied from place to place, being strongest in the Rocky Mountains. By factoring in the effects of temperature, moderate to strong associations in their analysis strengthened the conclusion that the extra lead came from wood burning.

1. Wood burners are a cult themselves, good luck with that.

2. There was a local guy with a wood-fired "outdoor furnace"

My God! The air in the little valley he lived in would become absolutely thick with smoke!

4. Those outdoor burners handle green wood

Completely unseasoned, no time to dry out first. Throw entire 5' logs in and go. They're actually banned by a lot of towns now.

If used with properly dried wood, they don't generate nearly that much smoke.

6. I believe they were banned in his area

At least I haven’t encountered a “Foggy Londontown” effect by his house for a few years.

3. Some of us are, unfortunately

I burn wood, but use a modern catalytic stove that meets EPA standards. I get all the free wood I need to heat my home off Marketplace giveaways and the local yard waste site.

I'm also on a Facebook page dedicated to wood stoves. There's a vocal subset there that thinks anything that uses modern tech to be more efficient and cleaner is a government conspiracy to take their stoves. They're kinda like the "rolling coal" diesel truck drivers or crazy gun nuts. And I'm over here like, I just don't want to have to go through 10 truckloads of wood a year, it's a lot of work to gather and chop all that, give me the most fuel efficient stove please.

5. I used to burn wood, but i just got tired of it, not to mention when i told my doctor

I had a wood stove he gave me a rash of shit about how unhealthy they are.
