Ambient Air Quality Statistics of India 1991 |
| Foreword
The main function of the Central Pollution Control Board (CPCB) under the Air
(Prevention & Control of Pollution) Act, 1981 is to improve the quality of air
and to prevent, control and abate air pollution in the country. Knowledge of the
current status of Ambient .Air Quality is essential for effective planning and
implementation of control programmes. Accordingly, the CPCB initiated action for
establishing National Ambient Air Quality Monitoring (NAAQM) network in 1984,
which by March, 1992 covered 290 stations spread over 89 cities and towns in 24
States and 4 Union Territories in the country. Moni- toring is conducted by the
respective state Boards and it sometimes takes more than 3 months for the data
to reach the Central Board. To eliminate such delays and keep upto date information,
efforts are being made to quicken the process of data flow. As a first step, data
transmission through floppies had been initiated.

| Presently,
State Boards are being connected to Central Board through a Nation-wide network
NICNET of the Na- tional Informatics Centre. The State Board of Himachal Pradesh
has already started sending the data through NICNET. I hope, with the establishment
of the network, upto date information of all the monitoring locations will be
available with the Central Board now. |
