The increase in pollution levels is usually attributed to vehicular movement and constructional activities, which heavily contribute to air pollution. These are usually not reported much in Rajendranagar. This apart, the green cover is more in this locality, when compared with other parts of the city, point out city-based environmentalists.

While the zoo park area has high traffic volumes, including those heading to destinations outside the city, there are also industries operating there.

The AQI values in the zoo park area remained in ‘Poor’ category and last year, the highest AQI value recorded here was 234. Air quality improves here during monsoon as rains help wash out pollutants.
