Pollution inside – Bus vs Plane

“It’s the best mask I’ve tried so far.”

Allen travel a lot and want to protect himself when he is in cities with heavy air pollution. He tried the TOTOBOBO mask and it appears to be the best mask he has tried so far. He ordered a bunch for his family because TOTOBOBO mask can fit the small faces of his children too.

As a traveler, pollution can exit in the most unexpected place. If it is not because of my previous research for a post (Say no to to pollution in school bus). I wouldn’t suspect there can be polluted air circulating inside a deluxe, aircond tourist coach.

Two weeks ago I took a SVIP coach from Singapore to Cameron Highlands. The seats inside this coach are large and the back can be lowered to almost flat- just nice for a good night sleep. The soft velvet feels comfy but I was curious to find out the air quality inside the bus.

I put on my mask during the overnight trip. We were required to get off the bus when crossing the border, and there were a couple of pee-stops during the night. I took off my mask when I need to get out of the bus and put it back on when I am getting back in.

When we reach Cameron Highland it was 7am in the morning, I was shocked to discover the gray patch collected on the filters- a clear indication of air pollution inside the coach, most likely from it’s own engine! The air quality along the route up Cameron Highlands at that time should be very clean.

To make sure I was not making this up, I decided to compare the result on a plane trip. I put on the mask with a clean set of filters on a business trip to Frankfurt. When I reach there after 12 hours, I can not see any noticeable sign of dirt. To be very sure about this, I put the same mask on during my flight back. Now it accumulated a total 24 hours of use in the plane. Judging from the color of the filter it is still very clean.

My conclusion? The air inside that coach is MUCH worst than the air inside the plane. It seems the air filter on plane is much more effective than those on buses, if the buses have any air filter at all.

Say No to Pollution in School Bus

School bus in USA

School bus in USA

Every day, half a million school buses safely carry 24 million American children to school, field trips and athletic events.

Unfortunately, most buses are powered by diesel engines that actually pollute the air inside the bus. Studies show the pollution gets trapped inside the bus, where kids breathe it in.
Soot from two sources

Pollution come from emissions from the tailpipe and from the engine. Engine emissions (also referred to as crankcase emissions) enter the school bus cabin mostly through the door and the floorboard.

Because the door is right near the engine, engine emissions get sucked into the school bus, every time the door opens.
Unhealthy diesel exhaust

Diesel engines spew out nearly 40 toxic substances, smog-forming emissions and particulate matter (PM), better known as soot. Coarse and fine particles (PM10 and PM2.5) are breathed deeply into the lungs where they can lodge, creating serious, even life-threatening health problems (more on the health effects of soot and the problem with diesel).

Children are at particular risk because their lungs are still developing. Kids also breathe two times more air per pound of body weight than adults do. The damage to young lungs can result in reduced lung function by adulthood and other dangerous health problems.

Particle Pollution Health Risks

• aggravated asthma
• lung inflammation
• heart problems
• possible cancer
• premature death

Children receive an extra dose of pollution twice a day

pollution in school bus

Children riding buses older than 2007 models receive an extra dose of pollution on each ride: monitoring shows that the diesel pollution inside a typical school bus can be up to five times higher than the outside air.

Unless your child’s school bus has been retrofitted with a filter or your child is riding on a brand new 2007 school bus, chances are, your child is breathing in unhealthy pollution levels.
Solutions are at hand

Science indicates that even short-term exposure to elevated particulate levels can have detrimental health effects. The good news is that children do not have to be exposed to diesel school bus pollution. Cost-effective solutions are available. Four Steps to Cleaner Buses.
To cut harmful soot pollution by 90 percent, a bus can be replaced with a new 2007 engine model year bus or retrofitted with a filtering device on the tailpipe, called a diesel particulate filter (DPF).

Engine emissions can easily be eliminated with a crankcase ventilation system (CCVS). A CCVS reroutes the engine emissions to the engine air intake preventing harmful emissions from escaping into the air and the bus cabin.

While working on the long term solution, the immediate action you may take is to install a personal filter (face mask) for your children. However, a surgical mask is useless since the airborne particulates can easily bypass the mask and enter the breathing zone through the gaps. N95 respirator is not available for children because NIOSH never certify any for use on children. Luckily TOTOBOBO mask is now available and it is the first fitting mask designed with the need of children in mind. Even though it is not certified, it is easy to see how it seal the small faces of children. There is even a choice of two different filters; 96% or 94%. The 96% provide higher protection level than N95 mask, and the 94% is only 1% less than N95 mask and has very low breathing resistance.
