Compact device measures level and source of PM 2.5

KYOTO--Precision tool maker Horiba Ltd. has developed a compact analyzer for PM 2.5 fine particulate matter that can identify individual constituents of the pollutant.
The environment-monitoring device combines concentration measurement and element composition analysis systems into one, drastically reducing the time needed to identify airborne components.
The product is the brainchild of Tomoki Aoyama, 32, an X-ray analyzer engineer in the company’s science and semiconductor department.
Although PM 2.5 pollutants are often understood in terms of size, the source of the problem lies in components of the airborne matter.
The device incorporates X-ray technology to identify the individual substances in PM 2.5, such as lead or sulfur, allowing appropriate countermeasures to be taken.
It was developed in response to a call from municipalities fighting air pollution and seeking a device that could swiftly analyze airborne substances.
Aoyama was a member of the 49th Antarctic research expedition team from 2007 to 2009.
Even though he succeeded in showing that sulfur levels increase in Antarctica in summer, he had bitter memories of having Horiba's heavy X-ray analysis equipment, at 120 kilograms, transported by helicopter to the observation area.
After returning to work, he started developing an alternative X-ray equipment. Three years in the making, in 2012, the new device weighed just 12 kg, one-10th of its predecessor.
Horiba announced in August development of the latest device. The company plans to sell the equipment to municipalities from 2015.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!
• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!
• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!
• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
