Warning!! PM2.5 Dust in Public Vans: A Silent Threat to Lung and Heart Health

A recent report from health authorities reveals that public vans in Bangkok and its surrounding areas are significant sources of severe air pollution, particularly PM2.5 dust and toxic diesel emissions. These pollutants pose long-term health risks to both passengers and drivers.

Studies show that PM2.5 levels inside vans are often higher than outside due to poor ventilation systems and the enclosed nature of the vehicles, which trap pollutants inside. Additionally, dust from brake pads, tires, and exhaust fumes from other vehicles can seep into the vans, further worsening air quality.

Health Risks of PM2.5 in Public Vans

Passengers traveling in vans are exposed to elevated levels of pollution, especially PM2.5, which consists of fine particles capable of penetrating the lungs and entering the bloodstream. This exposure can lead to various health issues, including:

     - Short-term effects: Eye irritation, nasal congestion, coughing, and difficulty breathing.

     - Long-term effects: Increased risk of chronic obstructive pulmonary disease (COPD), heart disease, and lung cancer.

     - Impact on the brain: Research suggests that prolonged exposure to PM2.5 may impair memory and increase the risk of dementia.

High-Risk Groups: Office Workers and Students

The most affected groups include those who regularly use vans, such as:

     - Office workers commuting for several hours daily.

     - Students who spend long hours in vans every day.

     - Van drivers exposed to polluted environments throughout their shifts.

Reports indicate that regular van passengers may have higher levels of toxins in their bodies compared to those using open-air public transport like buses or trains.

Proposed Solutions to Address the Issue

Experts recommend improving public transport systems to mitigate health risks. Possible measures include:

     - Transitioning to clean energy vehicles, such as electric vans or those powered by natural gas (NGV).

     - Installing air filtration systems inside vans to reduce dust levels.

     - Establishing air quality standards for vans, including regular PM2.5 monitoring.

     - Educating drivers and passengers about the dangers of air pollution and ways to protect themselves.

How Can the Public Protect Themselves?

While improving air quality in vans will take time, individuals can reduce their risk by:

     - Wearing PM2.5-filtering masks.

     - Choosing seats near ventilation openings to minimize dust inhalation.

     - Opting for alternative transport like air-conditioned buses or trains when possible.

     - Exiting the van and seeking well-ventilated areas if experiencing breathing difficulties.

Public Concerns and Feedback

Many commuters express limited alternatives, as vans are often faster and more convenient. However, concerns about air pollution are growing, especially during periods of high PM2.5 levels. Some passengers report symptoms like chest tightness, difficulty breathing, and nasal irritation while traveling in vans.

Van drivers also acknowledge the long-term health impacts of dust and exhaust fumes, with many experiencing chronic coughing or respiratory issues.

The Future of Public Transport in the Era of Air Pollution

The Thai government plans to promote clean-energy public transport to replace traditional systems, but this will require significant time and funding. Academics suggest that relevant agencies urgently improve air filtration systems in existing vans to reduce health risks.

In the meantime, passengers should remain aware of the dangers of PM2.5 and take proactive measures to protect themselves. Without immediate changes, public vans risk becoming “mobile pollution boxes” that threaten the long-term health of the Thai population.
