Wood burning is reintroducing lead pollution into the air, US scientists find

Study of samples from seven winters suggests neurotoxic metal coming from wood itself rather than old paintWood 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. Continue reading...
