Air Pollution: a problem to solve A.S.A.P. has been created for the purpose of promoting clean mobility solutions.

Some facts to consider:

  1. Air Pollution by Disc Brakes causes 20% of the total emissions by a standard car while many people never considered disc brakes to be a source of air pollution.
    "Vehicle tailpipe emissions are going down, but the emissions from disc brakes will remain to some extent, even if you drive an electric car," Weber said. "Therefore, this kind of process will continue to play out in the future and will be an important consideration when we look at the health effects of particulate matter." (
  2. Air pollution causes crime and unethical behaviour (
  3. Ultra-fine pollution (PM0.1) isn't yet officially measured in many cities (including London) while the particles have a greater impact on health. Ultra-fine particles can enter the blood stream and can't be filtered out by the body.

Air pollution causes crime and unethical behaviour

Recent studies have discovered a link between air pollution and crime. Polluted air causes negative emotions such as anxiety, which lead to a rise in criminal and unethical behaviour.

The evidence suggests that air pollution has the capacity to increase bad behaviour. But further research indicates that it can have even more serious impacts. One study of air pollution and crime in 9,360 US cities suggests that air pollution increases crime.

Recent research from the UK provides more evidence. By comparing data for 1.8 million crimes over two years with pollution data from London’s boroughs and wards. The analysis considered factors such as temperature, humidity and rainfall, days of the week and different seasons. The researchers found that a 10 point raise in the AQI increases the crime rate by 0.9 per cent. Levels of crime in London are therefore higher on the most polluted days. The study found that air pollution influenced crime in London’s wealthiest and poorest neighbourhoods. (

Bank managers, company leaders, politicians and scientists often work in cities. Air pollution may cause unethical decisions that has far-reaching implications for humanity as a whole.

Ethical thinking

Example: GMO yes or no?

Imagine a scientist or a politician having to decide on their support for GMO (genetically engineered food). Their intuition may say "no" but when they would care less about nature because air pollution forced them to have given up a part of their health, they may be more likely to take a gamble and postpone ethical consideration.

What ethical consideration may give people the intuition that GMO is bad? People may intuitively wonder: can life be a 'fixed state'? Genetic changes happen in nature but it happens as part of nature instead of being applied for a fixed result.

Most people believe intuitively that there is more to chemicals and genes that make them who they are. Therefor, they may intuitively want to give plants and animals a basis of respect for their spirit (a purpose of their existence that reaches beyond what can be measured). A stronger (purposeful) food source could be a stronger foundation for humanity.

Air pollution could have a profound effect on the ethics within daily decisions that could offset the optimal path of humanity.

Ultra-fine particles PM0.1, PM2.5 and PM10

Ultra-fine pollution not yet measured

How much ultra-fine dust PM0.1 is in the air in major cities? Unknown.

How much ultra-fine dust PM0.1 is emitted from disc brakes? Unknown.

Ultra-fine dust is not yet widely regulated, studied or measured. The effects on health are largely Unknown.

Impact on health

According to a recent study, PM0.1 ultra-fine dust is emerging as the most abundant pollution in cities.

Ultrafine particles (UFPs or PM0.1) are the fraction of ambient particulates with an aerodynamic diameter smaller than 0.1 microm. PM0.1 is emerging as the most abundant particulate pollutants in urban areas. Ultrafine particles have been less studied than PM2.5 and PM10 particulates.

UFPs represent an area of toxicology of emerging concern. (

PM0.1 (<0.1µm) particles have a greater impact on health than PM2.5 (<2.5µm) and PM10 (<10µm) particles, because:

  1. PM0.1 particles can easily get into the respiratory system and enter the blood stream.
  2. PM0.1 particles contain toxic elements such as heavy metals and hydrocarbons that can't be removed by the body.

The following link provides perspectives from students and scientists: How dangerous is PM0.1 for humans?
