Pollution display boards will 'smile or shed tears'

It has been reported that electronic boards that reveal pollution and air quality levels in Pune, India, will be revamped.

In contrast to numbers and figures, the boards will be replaced with an emotive face that will communicate to the public the current situation, Indian Express reveals.

The Air Quality Management Cell (AQMC) of the Pune Municipal Corporation has been working on the new system to replace the existing dull and unexciting display boards.

Ajay Ojha, head of the AQMC, says: "If the air quality is good, it will smile, if it is bad, it will be a weepy face.

"It requires converting the number into an expression. We have proposed five faces; certain air quality levels will be clustered and bunched against one face".

Close to 55 per cent of air pollution is caused by road dust, according to Mr Ohja. He claims that if just five per cent of motorists took public transport, air quality would improve substantially.

Pune is the eighth most populous city in India.
