Close on the heels of the tests for water quality inside the National Zoological Park, authorities have started conducting tests for checking the quality of air and noise quality at the park.
Officials from the Central Pollution Control Board (CPCB) carried out tests on Thursday and Friday at various locations inside the Park, popularly known as Delhi Zoo. "We had earlier sent the water samples for quality check. So we thought we might as well carry out test for air and noise pollution too," said zoo director Amitabh Agnihotri.
A railway loco-shade and the main railway line lie to the east of the zoo while the ever-busy Mathura road skirts its western edge. In February, a PIL in the Delhi High Court had sought shifting of the Delhi zoo stating that the animals, birds and other species suffered due to noise and air pollution, to which the zoo had responded.
"The court had not asked us to conduct any tests. But we thought, if we have the data, it can be of help later in the court case," Agnihotri added.
Noise levels were tested with the help of noise meters at 12 locations while respirable dust sampler (RDS) machines were put up at two locations. "The noise metre samples are taken every 15 minutes while air tests are conducted for eight hours a day," said Riaz Khan, the zoo's curator (education).
Zoo veterinarian S Pannirselvem said, "All these animals are breeding regularly, which is an indicator that the animals are comfortable here."
