How do we stay safe from a toxic threat that is mostly invisible? 

How do we stay safe from a toxic threat that is mostly invisible? Ciamar a ghabhas ar dìon bho chunnart phuinnseanach nach gabh fhaicinn?

Air pollution is killing thousands of people around the world every day. Cities across Asia and Europe have had to shut down and stop traffic to manage times when the air is unsafe. But air pollution is a killer everywhere, even places we think of as safe. How dangerous is the pollution we can’t even see?

New scientific research is showing the answers may be worse than we feared. A rise in dementia among dogs in heavily-polluted Mexico City led to a shocking discovery: microscopic particles of air pollution can travel from nerve cells in our noses directly into our brains.

In 2017, a study of 6.5 million Ontario health records confirmed that the closer you live to a major highway, the higher your odds of contracting dementia. Further research from USC in Los Angeles revealed that these airborne particulates actually shrink the brain, get into the bloodstream and even into the womb.

Nochdaidh RUDEIGIN SAN ÈADHAR gu bheil truailleadh èadhair a' marbhadh na mìltean air feadh an t-saoghail gach latha. Feumaidh bailtean air feadh Àisia is na Roinn Eòrpa dùnadh sìos agus trafaig a stad nuair nach eil an èadhar sàbhailte. Ach tha truailleadh èadhair marbhtach anns gach ceàrn, eadhon an àiteachan a shaoileadh sinn a bhiodh sàbhailte. Dè cho cunnartach 's a tha an truailleadh nach fhaic sinn?

Tha rannsachadh ùr a' sealltainn gur dòcha gu bheil cùisean nas miosa na bha dùil. Fhuaireadh lorg air rud uabhasach ri linn àrdachadh seargadh-eanchainn ann an coin ann am Baile Mheagsago: 's urrainn dha meanbh-mhìrean san èadhar an eanchainn a ruighinn tro nearbhan nan sròn.

 A rèir rannsachadh ann an 2017 air 6.5 millean clàr-slàinte  ann an Ontario mar as fhaisge a tha neach a' fuireach air mòr-rathad, 's ann as dualtaiche a tha iad fulang seargadh-inntinn. Nochd rannsachadh bho USC ann an Los Angeles gum bi na mìrean sin a' seacadh na h-eanchainn, a' dol a shruth na fala agus fiù 's dhan bholg.
