Foreword
The main function
of the Central Pollution Control 3oard (CPCB) under the Air (Prevention
& contrdl of pollution) Act, 1981 is to improve the quality of air
and to revent, 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 :ontrol progranunes. Accordingly CPCB
initiated establishing national Ambient Air Quality Monitoring (NAAQM)
network since 1984, which by March, 1991 covered 260 staions spread
over 75 cities/towns in 17 states and 4 union territories. Monitoring
is conducted by the respective state Boards and it takes 2 to 3 months
for the data to reach the Central Board. To keep upto date information
efforts are being made to quicken the process of data flow. As a first
step, the data flow through floppies has been initiated. Subsequently
the State BoardL will be connected to Central Board through on-line
network NICNET of National Informatics Centre. I hope, with the establishment
of on-line network, upto date information of all the monitoring locations
will be available with the Central Board.
