Catching ultrafine emissions could help develop cleaner cars

Scientists are developing a device to trap and analyse ultrafine particles from car exhausts.

Modern engines – in particular those which inject fuel at high pressure – maximise efficiency and cut carbon dioxide emissions, but may also release harder-to-catch pollution associated with cancers and lung, heart and Alzheimer’s diseases. In response, European researchers are analysing exhaust particles down to one billionth of a metre, which may help in the development of … Read more

Ultrafine pollution particles create air of menace

As many as 6.5 million premature deaths every year are attributed to air pollution, according to the World Health Organization.

An air quality study has for the first time detected nano-sized particles of air pollution in children’s urine. With a diameter of just 100 nanometers – a thousandth of the width of a human hair – these ultrafine particles are the smallest particles found in air pollution and have been linked to heart disease and respiratory conditions … Read more
