Arsenic found in London air raises fears over use of waste wood as fuel

Many people warming homes with wood from construction sites unaware of health risks, say experts

Arsenic particles are being spotted by scientists in London's air, as concerns grow that people are increasingly burning waste wood from construction sites while being unaware of the serious health risks.

Dr Anja Tremper at Imperial College London's air research station in south London tracked January's data and found arsenic particles in London's air, especially around the weekend of 2223 when air pollution reached the top index value of 10 on the UK government's scale.
