What is particulate matter and PM2.5 ?
DEFRA states: “Particulate matter is a term used to describe the mixture of solid particles and liquid droplets in the air. It can be either human-made or naturally occurring. Some examples include dust, ash and sea-spray.”
“PM2.5 means the mass per cubic metre of air of particles with a size generally less than 2.5 micrometres (µm). PM2.5 is also known as fine particulate matter.”
The first video shows people so scared of vape that they have donned facemasks, and carry out one of the most unscientific experiments on vaping ever conducted.
A vacuum pump pulls aerosol from a dripper and the host of the event declares it “simulates vaping”. Then he claims the box is completely sealed – but then is seen to place a monitoring device into a large opening.
At the end, he announces: “This experiment shows that the volume of PM2.5 in the e-cig aerosol is quite high.”
Some may wonder if all of the researchers were “quite high” when they devised the investigation.
The second video depicts a similar arrangement, but this one appears to have been conducted in someone’s bedroom – but has the added excitement of a laser pen.
The Thai Vapers advocacy group said: “Watch the experiment on PM2.5 in e-cig aerosol. What a misleading argument!”
Dr Konstantinos Farsalinos commented: “If you boil water you will have the same effect. This looks like 3rd world propaganda. Very sad. This is not even a way to measure droplets or anything else. This is pure kids' play in a playground.”
Dr Charles A. Gardner, Foundation for a Smoke-Free World observed: “Surprised they did not all wear HazMat Suits. Glad the guy with the vaporiser had a blast shield in case it exploded. I'm sure he wears that whenever using his cell phone.”
Then, in relation to particulate matter, added: “Which would you rather have fall on your head? A gallon of water or a bowling ball?”
American Vaping Association’s Gregory Conley pointed out: “They're not measuring harmful particles. They're measuring the presence of liquid droplets. Not a single person who vapes actually activates the device that long. The reason being is that it would start to burn the cotton. Which, we already know combustion is the worse source of PM in the air. This is junk science, and irresponsible research practices.”
