As the curtain closes on Bristol's year as European Bristol Green Capital, the city has potentially dangerous levels of air pollution.

In two months, the city has produced a high level of Nitrogen Dioxide mainly through the amount of cars on the road. The gas can cause coughs and shortness of breath as well as more serious respiratory illness - in Bristol nearly 200 people a year are thought to die early because of pollution.

On the same day the government was told it faces possible legal action for failing to tackle air pollution, the first vehicle to measure smog levels has arrived in Bristol.

The vehicle gauges pollution both inside and outside and has been driving around the city during rush hour.

However one person who knows all too well the damaging impact of pollution is Linda Moore-Kibbey. The city's air quality means she struggles to get around:

Data from this van shows Nitrogen Dioxide levels are 20% higher inside a vehicle than outside.

I think more and more people ought to be worried about that - particularly if you're driving your kids to school - you're sat in a box of pollution. We've created laws to ban smoking in cars yet we still have the situation where people are sitting in a vehicle full of pollution. They can't see it, it's invisible pollutant but it's still having an impact on their children's health and their own health.
