Air quality research supports calls to clean up the school run

17th February 2022

Research involving experts at Northumbria University outlines the health risks caused by harmful pollution from vehicles measured outside schools in Newcastle.

Air quality data from monitoring sites outside 12 schools in the city, covering a 24-month period, demonstrated that short-term levels of pollution, linked to patterns around school drop-off and pick-up times, would have consistently exceeded 2021 World Health Organisation (WHO) guidelines which are yet to be adopted into UK or EU policy.

Short term levels of Nitrogen Oxide (NO2) and tiny, inhalable particles called particulate matter (PM) recorded during the research were found to have exceeded 2005 and 2008 air quality guidelines and legal limits on several occasions.

Their findings have now been published in the international journal of scientific studies, Atmosphere, in a paper which recommends steps to improve air quality around schools to help protect the respiratory health of children, including road closures outside schools, anti-idling campaigns, staggered drop-off and pick-up times and relocating drop-off and pick-up sites away from school entrances.

Air pollution can cause suppressed lung growth, increased risk of asthma, wheeze and bronchitis.

Professor Namdeo, an expert in air quality management, monitoring and modelling from Northumbria University, said the respiratory health risks associated with the levels recorded demonstrated the need to act urgently to protect children in the city.

“This research confirms what we suspected in terms of the improvements needed to air quality near schools, providing a basis upon which to investigate why some schools in Newcastle experience noticeably worse ambient PM concentrations than others. We hope being able to demonstrate this variation will help to bring about change as part of discussions on the location of new schools, for example,” he explained.

As does the availability of reliable public transport.”

Dr Keast added: “Our research provides evidence which organisations can use to plan and implement policy at both a local and national level to protect children from the harmful effects of ambient air pollution during their day at school.”

The data used in the research was collected during 2018 and 2019 and came from sensors which were installed by the Urban Observatory as part of a partnership project with Newcastle City Council on healthy schools. The Urban Observatory is a pioneering project that monitors Newcastle and Gateshead at many levels such as for temperature, air pollution and traffic. The project also involved experts from Newcastle University’s Open Lab, who developed digital learning and interactive materials based on the data on air quality collected outside schools.

The city council is consulting on and introducing measures across the city to help reduce traffic, lower pollution levels and improve road safety while also working with Newcastle’s Promise Board – a group of headteachers, school governing bodies and academy trusts from across the city – to look at ways of promoting sustainable ways of getting to school.

Councillor Nick Forbes, Leader of Newcastle City Council, said: “It’s time for the school run to be cleaned up. It is detrimental to all our health and, as well as improving air quality, leaving the car at home gives wider health benefits from the exercise.

“We’re urging all parents and carers who can choose to walk, scoot or cycle to school to please leave the car at home or park further away to reduce pollution and congestion at the school gates. While we will continue to work with schools across the city to support and promote active travel, it is time for everyone to take responsibility for this and do what they can.”

The team of researchers from Northumbria are based within the department of Geography and Environmental Sciences, which encompasses research in environmental geochemistry and health, cold and paleo environments, social and cultural geographies, communities and resilience, and ecology.
