Air pollution in Portsmouth is a public health crisis. Poor air quality has been linked to many serious health conditions including heart disease, breathing problems and Alzheimer’s. Most pollution in Portsmouth is caused by road traffic, particularly in the form of nitrogen dioxide (NO2) released by diesel vehicles. The EU and UK government specified maximum legal NO2 limits that were to be met by 2010. However, some roads in Portsmouth often exceed this limit. Portsmouth City Council is responsible for reducing pollution to safe limits.
There is no safe level of exposure to diesel fumes and we should be targeting a pollution level that is significantly below the legal limit. Apart from NO2 levels, pollution from particulates is also a concern in Porsmouth.

21 September 2017, Full report
Portsmouth City Council operates a network of pollution monitoring stations throughout the city. Portsmouth currently has five air quality management areas where levels of NO2 are of particular concern. These include the area from Fratton Bridge via Kingston road to London Road in North End, the High Street in Old Portsmouth, the Eastern Road along Milton Common, Mile End Road as it turns into the M275, and Queens Street by the Naval Base.
NO2 diffusion tube (NDDT) monitoring found unsafe NO2 levels at 6 sites (above the allowed annual mean NAQO of 40μg/m3), mostly in the air quality management areas above. The highest NO2 readings were recorded at The Tap pub in North End (49μg/m3). The Northern Road area in Cosham and Albert Road in Southsea both show signs of significant deterioration.
The continuous NO2 monitoring program found an increase in NO2 most sites since 2015. "[Compared to 2015, the] 2016 NO2 annual mean level increased across the four [continuous monitoring sites] ... to result in a worsening in LAQ [Local Air Quality]. The maximum recorded concentration was at London Road kerbside CAQMS (41.21μg/m3). This level breaches the NO2 annual mean NAQO" However, the 5 year trend from most of these sites is broadly unchanging (i.e. dangerously high).
