Every Organ Is Affected by Car Pollution, Experts Suggest

Pollution lurks in our cities, silently penetrating our lives and bodies. Recent studies reveal a disturbing reality: air pollution doesn't spare any organ in the human body. This discovery is a wake-up call for everyone, demanding immediate action to reevaluate the quality of the air we breathe and its profound impact on our well-being.

Every Organ Is Affected by Car Pollution

The Invisible Killer

Environmental scientists once squared air pollution as primarily a respiratory irritant, prime to worsen asthma or cause bronchial infections. Today, the scope is horrifically wider. Airborne pollutants have been shown to permeate the lungs and enter the bloodstream, systematically infiltrating different organs. This insidious journey, invisible to the eye, can result in conditions spanning from heart disease to diabetes and even mental health disorders.

Heart and Blood Vessels

Exposure to pollutants like particulate matter (PM2.5), tiny particles small enough to enter our organ systems, has been linked with an increased risk of heart attacks, strokes, and high blood pressure. These particles, often emitted by diesel engines, can provoke inflammation that leads to chronic cardiovascular diseases.


It doesn't stop with the heart. Neurological consequences are increasingly being tied to poor air quality. From cognitive decline to heightened stress responses and potential links with dementia, the evidence suggests that what we breathe could be altering the very fabric of our cognitive functions.


While it may be obvious that pollution impacts lung health, the extent is alarming. Asthma, chronic obstructive pulmonary disease (COPD), and lung cancer are on the rise, with a direct correlation to the toxic air that envelops many urban environments.

Campaign for Clean Air

In England alone, a quarter of all trips are less than a mile. Larissa Lockwood, Director of Clean Air at Global Action Plan, explains that air pollution affects more than just our lungs. It poses risks to our entire body. However, there is hope. Simple actions like walking have positive effects on our health and communities.

To encourage walking and cycling for short trips, Clean Air Day calls on those who can leave their cars behind. In addition to reducing your air pollution footprint and exposure, walking is the most cost-effective and healthy way to get around. But we acknowledge that it's not always easy. The environmental charity is advocating for local decision-makers to create environments that make walking more accessible and promote cleaner air in communities.

Dr. Karen Exley from the UK Health Security Agency emphasises that air pollution has various detrimental effects on our health and can even shorten our life expectancy. Taking action now to improve air quality could prevent countless respiratory and cardiovascular diseases in the coming decades. Each of us shares the responsibility to reduce air pollution, and campaigns like Clean Air Day demonstrate how every action makes a positive impact.

Dieselgate and Its Aftermath

Diesel engines, found in many cars, buses, and trucks, have been touted for their fuel efficiency and longevity, but they also have a darker side: the emission of NO2 and fine particulate matter, which is particularly harmful to lung development and function. 

Dieselgate became a cautionary tale about corporate deception and regulatory failure when it was revealed that Volkswagen—and later other manufacturers—were programming diesel engines to pass emissions tests while emitting up to 40 times the legally allowable NO2 levels during normal operation. This scandal, detailed on among others, has contributed significantly to the global conversation on vehicular pollution and its health impacts.

The aftermath of Dieselgate sparked a wave of legal action from consumers and governments alike. Diesel emission claims became a means for wronged parties to seek compensation and push for change. These legal moves demand transparency and accountability from automakers while encouraging stricter emissions regulations and cleaner air standards.

Vulnerable Groups

The burden of pollution does not fall equally across populations. The impact of poverty and social inequality on communities exposed to pollution is severe, as they lack the means to protect themselves from environmental damage or seek better living conditions. The resulting health issues further worsen their financial instability, creating a never-ending cycle of vulnerability. This pattern suggests a grave environmental justice issue, where the health impacts of pollution are intertwined with socio-economic status and access to clean environments.

Paving the Way for Cleaner Air

The high price of not taking action is evident in our overall health and the preservation of our environment. The fight against pollution is daunting but far from hopeless. Innovations in clean energy and technologytechnology offer a glimpse into a future where clean air is not just a privilege but a standard. Transitioning to a greener economy is not just an environmental imperative but a necessity for public health.

As haunting as this new data might be, it can catalyse action, a challenge to each of us to consider how our choices today shape the air we breathe tomorrow. Now is the time to make informed choices, advocate for systemic change through diesel claims, and embrace cleaner, healthier living.
