Portsmouth City Council performs an annual review and assessment of pollution in Portsmouth to meet the statutory obligations. These are set according to the Department for Environment Food and Rural Affairs (DEFRA) Local Air Quality Management Technical Guidance. To achieve this, air quality is monitored with the help of continuous monitoring stations at key locations across the city which provide the Air Quality team with real-time air quality monitoring data.
In Portsmouth, the main pollutants which may impact on human health are principally the products of combustion from road traffic – mainly nitrogen dioxide. Currently there are five Air Quality Management Areas (AQMAs) predicted to exceed the annual nitrogen dioxide National Air Quality Objective (NAQO). Their locations are represented in red on the ‘AQMA Locations’ map, available in the documents section below.
There are five continuous air quality monitoring stations, which provide nitrogen dioxide results, PM2.5 and PM10 monitoring capabilities. Portsmouth City Council has already installed increasing volumes of nitrogen dioxide diffusion tube monitors in areas of concern.
