Quelles sont les meilleures pratiques pour gérer la pollution de l’air dans les villes densément peuplées?

In 2019, World Health Organization (WHO) has considered air pollution as “the greatest environmental risk to health”. The use of private vehicles (particularly older, diesel models) is the major source of urban air pollution.Half of the world population still relies on solid fuels for cooking and heating. These fuels, including wood, charcoal and coal, are burned in inefficient stoves that release large quantities of health-damaging particulate matter and climate warming pollutants into the nearby environment. Industrialization is also a major contributor to urban air pollution as the area having industries particularly show poor air quality.

Potential air pollution sources in densely populated areas may include outdoor sources such as vehicular, traffic, and industrial emissions, outdoor garbage burning, improper refuse disposal as well as indoor sources such as biomass fuel use in cooking. In densely populated areas, poor ventilation practices often tend to exacerbate air pollution levels.

Identifying and measuring sources of air pollution is crucial for effective management in densely populated cities. These sources encompass both natural and human-made factors, such as traffic, industry, power plants, waste, wildfires, dust, and volcanoes. Common pollutants include particulate matter (PM), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO), each with distinct impacts on human health and the environment. Monitoring pollutant levels accurately is essential, employing reliable methods and devices to track trends and inform targeted mitigation strategies.

Managing air pollution in crowded cities requires a mix of smart strategies and community effort. Expanding public transportation, promoting clean energy, and increasing green spaces can help reduce emissions. Adopting air quality monitoring systems ensures targeted action, while raising public awareness empowers people to contribute through small, meaningful changes. What solutions do you think could create the most lasting impact in such cities?

The only ways to drastically reduce air pollution are to adopt a wide range of policies that regulate all polluting industries – from energy production to transportation and agriculture – as well as to reflect on broader solutions such as carbon tax systems. 1. Cut Down Emissions from Power Plants 2. Decarbonise the Global Transport Sector 3. Adopt a More Sustainable Approach to Agriculture 4. Improving Air Quality While Fighting Climate Change

Usage of natural gas powered public transportation would reduce emissions. Usage of electric vehicles will only increase pollution.

Make cleaner energy sources are easily accessible, provide subsidies on cleaner energy sources if possible. Focus on educating and enlightening the public on the benefits of using cleaner energy sources.

Implementing strategies to reduce emissions is pivotal in managing air pollution in densely populated cities. This entails a multifaceted approach, including setting emission standards, promoting cleaner fuels and technologies, enforcing regulations, incentivizing low-carbon and renewable energy sources, enhancing public transport and mobility options, advocating for active travel and green spaces, and fostering awareness and education. These measures yield numerous benefits, spanning from mitigating air pollution and climate change to bolstering energy security, reducing costs, and generating employment opportunities.

On industrial level - Air pollution control devices are a series of devices that work to prevent a variety of different pollutants, both gaseous and solid, from entering the atmosphere primarily out of industrial smokestacks. These control devices can be separated into two broad categories - devices that control the amount of particulate matter escaping into the environment and devices that control acidic gas emissions. Although complex, these devices have shown to be effective in the past with the overall levels of emissions for many pollutants dropping with the implementation of these control devices.

In the near future , use of hydrogen powered vehicles will eliminate the need for gas or diesel, until then conversion to natural gas public transportation, is the answer.

No matter who or what monitors air quality , it should not be the federal government, and it would be best if no government entity was involved.

Their should be no compensation of any individual by tax dollars. No one is unfairly subjected to “unfair” air quality standards.

Toxic pollution travels from country to country, carried by air and water with no respect for borders. This means that even places with relatively clean air can be subjected to air pollution events. Countries must work together.

Again, any collaboration needs to be done by private and third party entities, government should not be involved. Especially the federal government who is inefficient, ineffective, and deliberately pushing unfounded ideas and policies.
