3.2 National Air Monitoring Programme (N.A.M.P.) Central Pollution Control Board initiated National Ambient Air Quality Monitoring (NAAQM) programme in the year 1984 with 7 stations at Agra and Anpara. Subsequently the programme was renamed as National Air Monitoring Programme (N.A.M.P.). The number of monitoring stations under N.A.M.P. has increased, steadily, to 295 by 2000-01 covering 98 cities/towns in 29 States and 3 Union Territories of the country. 3.2.1 Objectives The objectives of the N.A.M.P. are as follows: • To continue ongoing process of producing periodic evaluation of air pollution situation in urban areas of the country. • To determine status and trend in ambient air quality and effects of air pollution in urban environment • To estimate the future worsening or improvement of air quality and to obtain the knowledge and understanding necessary for developing preventive and corrective measures. • To understand the natural cleansing process undergoing in the environment through pollution dilution, dispersion, wind based movement, dry deposition, precipitation and chemical transformation of pollutants generated. • To ascertain whether the prescribed ambient air quality standards are violated and to assess health hazard, damage to materials and to control and regulate pollution from various sources. 3.2.2 Monitoring Locations and Parameters Under N.A.M.P., four air pollutants viz., Sulphur Dioxide (SO2), Oxides of Nitrogen as NO2 and Suspended Particulate Matter (SPM) and Respirable Suspended Particulate Matter (RSPM/PM10), have been identified for regular monitoring at all the locations. Besides this, additional parameters such as Respirable Lead and other toxic trace metals, Hydrogen Sulphide (H2S), Ammonia (NH3) and Polycyclic Aromatic Hydrocarbons (PAHs) are also being monitored in 10 metro-cities of the country, since 1990. The monitoring of meteorological parameters such as wind speed and direction, relative humidity and temperature was also integrated with the monitoring of air quality. The growth of monitoring network is shown in Figure 3.1. 70
Number of Monitoring Stations 350 300 250 200 150 100 50 0 28 The monitoring of pollutants is carried out for 24 hours (4-hourly sampling for gaseous pollutants and 8-hourly sampling for particulate matter) with a frequency of twice a week, to have 104 observations in a year. N.A.M.P., being a nationwide network, involves several agencies which are: • Central Pollution Control Board: in Delhi; • State Pollution Control Boards : in the respective States; • Pollution Control Committees: in the respective Union Territories; • National Environmental Engineering Research Institute (NEERI), Nagpur: in 10 metro cities of the country; • Visvesvaraya Regional College of Engineering, Nagpur: in the city of Nagpur; • University of Pune, Pune: in the city of Pune; • KTHM College, Nasik: in the city of Nasik ; 53 • Walchand Institute of Technology, Solapur: in the city of Solapur; and • Thane Municipal Corporation in the city of Thane 84 106 150 71 220 260 1985 1986 1987 1988 1989 1990 1991 1992- 99 Years 290 295 2000- 01 Figure 3.1: Growth of Ambient Air Quality Monitoring stations under N.A.M.P.
