Cooking on a gas hob can create higher levels of indoor air pollution than found on one of the UK’s busiest roads, a study has found.

The research by Which? compared levels of two of the most damaging air pollutants – nitrogen dioxide (NO2) and fine particulate matter (PM2.5) – in the homes of four people with gas hobs, one person with an induction hob and on Marylebone Road in central London.
