Delhi’s radical road rationing plan kicks in from the new year as a desperate city struggles to clean up its filthy air.

A lungful of air in Delhi is a noxious mix of smoke, dust, fumes and ash with heavy concentrations of chemicals, acids, metals and carcinogens. What makes this “particulate matter” so deadly is its size - the particles are small enough to pass through the nose and throat, and even penetrate tissue. The tiniest, which are 2.5 micrometers or less in diameter (PM 2.5), are the worst. They are more toxic, travel farther from their source and live deep in lung tissue.

Although Delhi’s (and India’s) air has gotten progressively worse - a 2014 report said air quality in the country has declined 100 percent in the last decade - contributions from different pollutants have shifted over the years.
