PUPILS have been giving their school a "green bill of health" this week.
To coincide with Green Week, pupils from Cassop Primary School announced the cleanliness of their environment.
They discovered this during Pollution Fortnight, a Barclaycard LivingLand initiative run in conjunction with the Young People's Trust for the Environment.
Children and teachers at the school were asked to measure pollutants from nitrogen oxide to lead in playground dust during a two-week period in January.
At the end of the experiment, data from all 22 UK schools involved was sent to the University of Surrey, Roehampton, where a team of scientists analysed it.
Cassop Primary School's results showed levels of benzene and nitrogen dioxide that were well within recommended levels.
The university's Dr Jonathan Horner said: "Children are especially susceptible to many pollutants and so it was particularly relevant to measure levels of pollution in school playgrounds."
