Agra, Nov 5 (TIWN) Restrictions on firecrackers temporarily helped bring the noise pollution level down in Agra, but the two-hour window neutralized the gains made in the preceding two days.

Air pollution levels caused by dust, vehicular emissions, and fireworks plus the fog, sent alarming health signals, doctors said on Friday. The district administration had issued guidelines and allowed only 144 counters at a dozen locations in the city, for the sale of green crackers.
