Summary

Story summary

Cambridge researchers published a review linking higher air-pollution exposure to increased Parkinson’s disease risk.
Based on 26 studies, a 5 ug/m³ rise in PM2.5 and a 15 ug/m³ rise in PM10 raise Parkinson’s risk by 10 % and 18 % respectively.
The review found no link between Parkinson’s and nitrogen dioxide, carbon monoxide, sulphur dioxide, ozone, soot, multiple sclerosis or motor neuron disease.
Dr Haneen Khreis’s team released a tool mapping over 1,000 traffic-emission interventions for policymakers.
