Now, smartphones that monitor pollution around you

Researchers have developed a new sensing technology through which smartphone users will get to know about the pollution levels around them.

The scientists of American Chemical Society examined 50 school children equipped with smartphones measured the ambient levels of black carbon and analysed that children contribute 13 percent of their total potential in black carbon exposure.

Mark J. Nieuwenhuijsen and colleagues concluded that smartphone technologies could contribute valuable new insights into air pollution exposure, and prevent many from respiratory and cardiovascular problems.

The research is published in a journal Environmental Science and Technology.
