NEW DELHI: Delhi authorities have imposed a three-day ban on trucks entering the world’s most polluted major city as its 20 million inhabitants wheezed in the toxic annual winter smog.
With levels of air pollution classed as “hazardous,” the restriction on the nearly 40,000 medium and heavy lorries that enter Delhi every day was imposed late Thursday.
On Friday, levels of particulates 2.5 micrometers or less in diameter, the most harmful to human health, peaked at 845, according to the US embassy website that monitors air quality independently.
