Schools' Role In Pollution Control And Prevention

Schools can play a vital role in reducing pollution and its harmful effects on children's health. There are several measures that schools can take to tackle pollution, including encouraging children to walk to school and stay away from roads with high traffic, installing carbon dioxide monitors in classrooms, and turning off lights and taps when they are not in use. By implementing these strategies, schools can significantly reduce children's exposure to pollutants and improve the air quality in their surroundings.

Teach students about pollution prevention

Teaching students about pollution prevention is an important step in tackling pollution. Teachers can explain to their students how they can prevent pollution and why they should. This will empower students to become agents of change, influencing their friends and families to do the same.

There are several techniques that can be taught to students to prevent pollution. For example, students can be encouraged to avoid vehicle use during drop-off hours, which would reduce their exposure to harmful vehicular pollutants. Schools can also promote walking or cycling to school, and stress the importance of staying away from the edge of the road when walking to or from school, as pollutant concentrations are highest in the first metre from ground level.

Teachers can also suggest alternative, cleaner routes to school, such as passing through parks. Students can be taught about the negative health effects of high carbon dioxide levels, such as tiredness, inability to think clearly, headaches, and dizziness. They can then be encouraged to open windows later in the day or if they feel hot or tired, to draw fresh air into the classroom.

Schools can also implement simple measures to prevent pollution, such as using "half-lighting" in classrooms (only turning on half the lights) if there is enough natural lighting, and turning off monitors, lights, and taps when they are not in use.

Avoid vehicle use during drop-off hours

Avoiding vehicle use during drop-off hours could result in a threefold reduction in school children’s exposure to harmful vehicular pollutants. Schools should encourage children to walk to school, for example, through accreditation and behaviour change schemes.

To encourage walking, schools should work with local authorities to ensure that new schools are strategically located in areas away from main roads, with safe walking/cycling passages to link the school premises with main connecting roads as well as housing/communities. Schools should also stress the significance of high pollutant concentrations at lower heights to parents/children and suggest alternative, cleaner routes (e.g. passing through parks).

Schools should also discourage parents from waiting in a queue of cars with their engines on during drop-off hours. Schools could suggest that parents park their cars away from the school and walk their children to the school gates, or that they stagger their arrival times to avoid congestion.

In addition, schools could implement a 'park and stride' scheme, where parents park their cars in a designated car park away from the school and walk the rest of the way with their children. This would reduce the number of cars near the school and encourage walking.

Install carbon dioxide monitors in classrooms

Installing carbon dioxide monitors in classrooms is an effective way to ensure that schools are not contributing to pollution. Teachers should be made aware of the symptoms of high carbon dioxide levels, such as tiredness, inability to think clearly, headaches and dizziness. If these symptoms are noticed, windows should be opened to draw fresh air into the classroom.

Doors and windows that immediately face a road should be kept closed during peak hours to prevent outdoor pollutants from entering the classroom. During off-peak hours, these doors and windows can be opened to allow for air exchange.

To further mitigate indoor air pollution, schools should consider investing in clean air purifiers or filters. These should be regularly maintained and cleaned to ensure their effectiveness. Alternatively, schools can set up proper air filtration and ventilation systems.

In addition to these measures, schools should encourage children to walk or cycle to school instead of being dropped off by car. This can be achieved through accreditation and behaviour change schemes. By reducing the number of cars outside the school during drop-off hours, schools can significantly decrease children's exposure to harmful vehicular pollutants.

Encourage local authorities to move traffic intersections and bus stops away from school premises

Schools can play a vital role in reducing pollution by encouraging local authorities to relocate traffic intersections and bus stops away from their premises. This strategy is based on the understanding that pollutant concentrations are typically highest within the first metre from ground level and decrease with distance from the road. By moving these traffic hotspots away from schools, students and staff can benefit from cleaner air and a healthier learning environment.

To achieve this, schools can engage in constructive dialogue with local authorities, presenting compelling arguments and scientific data to support their case. They can highlight the potential health risks associated with high levels of pollution, particularly for children who are more vulnerable to its adverse effects. Schools can also emphasise the long-term benefits of such a move, including improved air quality, reduced exposure to harmful vehicular pollutants, and enhanced well-being for the entire school community.

Additionally, schools can propose alternative locations for traffic intersections and bus stops that are safer and more conducive to the overall well-being of the area. These suggestions should consider factors such as proximity to main roads, the availability of safe walking and cycling passages, and the impact on surrounding communities. By presenting well-thought-out proposals, schools can demonstrate their commitment to finding a solution that benefits everyone.

While recognising that relocating traffic intersections and bus stops may not always be feasible, schools can explore interim measures to mitigate the impact of pollution. This includes educating students and parents about the importance of staying away from the edge of the road when walking to or from school and suggesting alternative, cleaner routes that minimise exposure to vehicle exhausts. Schools can also advocate for behaviour change schemes that encourage more children to walk or cycle to school, reducing the number of vehicles during drop-off and pick-up hours.

Furthermore, schools can collaborate with local authorities to implement strategic planning for new schools. This involves selecting locations away from main roads and ensuring the presence of safe walking and cycling passages that connect the school premises to surrounding communities. By proactively considering pollution prevention in the siting of new schools, local authorities can make a significant contribution to improving air quality and the health of future generations.

Stress the significance of high pollutant concentrations at lower heights to parents and children

Schools can play a vital role in reducing pollution and its adverse effects on children's health. One key aspect is stressing the significance of high pollutant concentrations at lower heights to parents and children. Here's why this is important and what schools can do about it:

Pollutant concentrations are typically highest in the first metre from the ground and decrease with distance and height from the road. This means that children, who are generally closer to the ground, are more vulnerable to inhaling higher levels of pollutants. Schools should educate parents and children about this issue and suggest alternative, cleaner routes to school that avoid busy roads. For example, walking through parks or other green spaces can reduce exposure to vehicle exhaust fumes.

To further reduce pollution levels, schools can encourage children to walk or cycle to school instead of being driven. This not only lessens the number of cars on the road but also ensures that children are not sitting in idling cars, which can expose them to harmful vehicular pollutants. Schools can support this by implementing accreditation and behaviour change schemes that reward active travel.

Additionally, schools can take measures to improve indoor air quality. Carbon dioxide monitors can be installed in classrooms, and windows can be opened during off-peak hours to allow for air exchange without letting in too much outdoor pollution. Proper air filtration and ventilation systems can also be set up to mitigate indoor air pollution and minimise the infiltration of outdoor pollutants.

By stressing the significance of high pollutant concentrations at lower heights and implementing these other strategies, schools can play a crucial role in reducing children's exposure to pollution and its associated health risks.
