Bad Breath With Xand Van TullekenOctober 8, 2018

Imagine if you could change the quality of the air we breathe - in just one day. Air pollution in the United Kingdom has been declared a public health emergency by a cross-party group of MPs, and Dr Xand van Tulleken is seeing what can be done about it. Enlisting the help of enthusiasts and sceptics from the Kings Heath community in Birmingham, Xand stages the first ever large-scale experiment of its kind - using people power to try and bring about a quantifiable improvement in air quality for a single day.

Bad Breath With Xand Van Tulleken was broadcast on SBS ONE at Sunday 28 March 2021, 17:40. This episode was initially placed on Monday 8 October 2018.
