This topic area covers statistics and information relating to air pollution in Hull including local strategic need and service provision. Further information is also available about Hull and the environment can be found under Geographical Area within Place, and under Climate Change within Health and Wellbeing Influences.
This page contains information from the Office for Health Improvement & Disparities’ Fingertips. Information is taken ‘live’ from the site so uses the latest available data from Fingertips and displays it on this page. As a result, some comments on this page may relate to an earlier period of time until this page is next updated (see review dates at the end of this page).
Headlines
- Humans interact with the environment constantly. These interactions affect quality of life, years of healthy life lived, and health disparities.
- Over 5% of all deaths among those aged 30+ years are attributable to air pollution in Hull.
- There is the potential for measures introduced to resolve one environmental problem to be detrimental to other strategies, so full consultation and engagement between the different areas and an assessment of the impacts of any council actions is essential to ensure strategies complement each other.
The Population Affected – Why Is It Important?
The UK’s air quality strategy details how the UK aims to achieve prescribed standards and objectives for a suite of air quality concentrations to protect health and the environment. These include nitrogen dioxide, sulphur dioxide and particulate matter smaller than 10 microns (PM10), with an additional requirement for particulate matter smaller than 2.5 microns (PM2.5).
As people are generally more affected by one pollutant than another, locally it is felt that presenting the values of the individual pollutants rather than the Air Pollution Index (API) enables people to make more informed personal decisions. The NHS have summarised some research on lung cancer and heart failure in relation to air pollution. For a lung cancer study, each 10μg/m3 increase in PM10 led to a corresponding increase in the hazard ratio of lung cancer incidence of 1.22 (95% confidence interval 1.03 to 1.45) with no association found between lung cancer incidence and PM2.5, mono nitrogen oxide and nitrogen dioxide combined, or nitrogen dioxide. The heart failure study found an increased risk of heart failure hospitalisation or death for increases in carbon monoxide (3.5% increase in risk per increase of one part per million of pollutant), sulphur dioxide (2.4%), nitrogen dioxide (1.7%), PM2.5 (2.1%) and PM10 (1.6%). In both studies, some potential confounders were included in the model, but it is possible important confounders were not included.
Different factors influence different pollutants in relation to air pollution as illustrate by Health Matters from the Office for Health Improvement & Disparities (formerly Public Health England).
Air pollution affects individuals throughout their entire lifetime.
The Hull Picture
Hull City Council has a very good story to tell regarding air quality so far, and it measures air quality across the city, with results used to inform planning policy and applications as well as the Action Plan Measures in the Council’s Air Quality Strategy and an Annual Status Reports (ASR) which is sent to the Department for Environment, Food and Rural Affairs’ (DEFRA). Levels of mono nitrogen oxide, nitrogen dioxide, mono nitrogen oxide and nitrogen dioxide combined, sulphur dioxide, PM10 and PM2.5 are all measured.
Air quality in Hull is better than most areas of a similar nature, and is generally improving, with only one area exceeding the air quality objectives. This is an area close to the A63, and the road improvements that are ongoing are designed to remove this exceedance. The Council’s Air Quality Strategy aims to ensure that existing levels do not increase, and are reduced further wherever possible. The highest pollution concentrations are along the south edge of Hull (A63), near the train/bus station, and near the industrial areas (up the centre of Hull from South to North approximately route of river and the A1033) and around the Docks (in South-East corner (Marfleet ward) of Hull), although as mentioned only an area around the A63 exceeds the National Air Quality Objectives.
The Committee on the Medical Effects of Air Pollutants (COMEAP) estimated that if all man-made particulate pollution were removed, this would lead to an increase in life expectancy of around 6 months although the effect could be as small as one month and as large as a year. To put this into context, the effect on life expectancy of continued smoking is seven years on average. Nevertheless, mortality attributable to particulate air pollution has been modelled for Hull for 2017 from DEFRA’s modelled pollution concentrations, the number of deaths to persons aged 30+ years and the relative risk of 6% increase in mortality per 10μg/m3 PM2.5 estimated by COMEAP.
The Office for Health Improvement & Disparities’ Fingertips provides an estimate of percentage of deaths among those aged 30+ years attributable to air pollution, However, DEFRA’s model for Hull was found to be inaccurate, and as a result it is possible that the percentages of deaths based on these levels of air pollution may also be inaccurate.

Source: Background annual average PM2.5 concentrations for the year of interest are modelled on a 1km x 1km grid using an air dispersion model, and calibrated using measured concentrations taken from background sites in Defra’s Automatic Urban and Rural Network (http://uk-air.defra.gov.uk/interactive-map.) Data on primary emissions from different sources and a combination of measurement data for secondary inorganic aerosol and models for sources not included in the emission inventory (including re-suspension of dusts) are used to estimate the anthropogenic (human-made) component of these concentrations. By approximating LA boundaries to the 1km by 1km grid, and using census population data, population weighted background PM2.5 concentrations for each lower tier LA are calculated. This work is completed under contract to Defra, as a small extension of its obligations under the Ambient Air Quality Directive (2008/50/EC). Concentrations of anthropogenic, rather than total, PM2.5 are used as the basis for this indicator, as burden estimates based on total PM2.5 might give a misleading impression of the scale of the potential influence of policy interventions (COMEAP, 2012).
Strategic Need and Service Provision
Hull’s improving year on year trend relating to air quality has been maintained with the Council’s Air Quality Strategy, and an increase in background levels are prevented. Continuing to raise awareness of the health and financial benefits of good air quality is a key measure in encouraging behaviour change and less polluting lifestyle choices.
It is necessary to work together to maintain and expand an environment that promotes active travel for all ages in order to reduce the impact on air pollution from cars. Food production also has a substantial impact on air pollution, particularly meat and manufactured food products. Raising awareness of this and encouraging people to buy locally produced food could all help to reduce air pollution levels.
It is important that any measures in the proposed climate change strategy and proposed action plan consider the implications on and as far as possible complement those in the Air Quality Strategy, as some could have a detrimental impact on air quality. For example, monitoring during the COVID-19 lockdown indicates that as direct emissions from vehicles decrease (mono nitrogen oxide and nitrogen dioxide combined) it has the potential to result in an increase in the concentrations of other potentially harmful gases, such as ozone, and only a minimal reduction in the emissions of particulate matter. This has implications and will need to be considered when advocating a change to electric vehicles.
