AIR QUALITY


National Air Quality Monitoring Programme (NAMP)

MANDATE

Air (Prevention and Control of Pollution) Act, 1981 Government of India enacted to arrest the deterioration in the air quality. The act prescribes various functions for the Central Pollution Control Board (CPCB) at the apex level and State Pollution Control Boards at the state level.

The main functions of the Central Pollution Control Board are as follows:

- To advise the Central Government on any matter concerning the improvement of the quality of the air and the prevention, control and abatement of air pollution.

- To plan and cause to be executed a nation-wide programme for the prevention, control and abatement of air pollution.

- To provide technical assistance and guidance to the State Pollution Control Board.

- To carry out and sponsor investigations and research related to prevention, control and abatement of air pollution.

- To collect, compile and publish technical and statistical data related to air pollution; and

- To lay down and annual standards for the quality of air.


The main functions of the State Pollution Control Boards are as follows:

- To plan a comprehensive programme for prevention, control and abatement of air pollution and to secure the execution thereof;

- To advise the State Government on any matter concerning prevention, control and abatement of air pollution.

- To collect and disseminate information related to air pollution.

- To collaborate with Central Pollution Control Board in programme related to prevention, control and abatement of air pollution; and

- To inspect air pollution control areas, assess quality of air and to take steps for prevention, control and abatement of air pollution in such areas.

World Health Organization (WHO) GUIDELINES

 

WHO GUIDELINES FOR AIR QUALITY

WHO’s work on environmental health provides the basis for global standards in environmental quality and an effective investments for public health such as air quality guidelines and drinking water quality guidelines. The “WHO air quality guidelines” provide an assessment of health effects of air pollution and thresholds for health-harmful pollution levels.

National Air Quality Monitoring Programme (NAMP)

OBJECTIVE OF NATIONAL AIR QUALITY MONITORING PROGRAMME (NAMP)

Central Pollution Control Board is executing a nation-wide programme of ambient air quality monitoring known as National Air Quality Monitoring Programme (NAMP). The network consist of 625 operating stations in 263 cities/towns in 29 states and 5 Union Territories of the country.


The objectives of the N.A.M.P. are:

- To determine status and trends of ambient air quality;

- To ascertain whether the prescribed ambient air quality standards are violated;

- To Identify Non-attainment Cities;

- 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.

National Air Quality Monitoring Programme (NAMP)

MONITORING NETWORKS


Frequency and Parameters Monitored

Under N.A.M.P., three air pollutants viz., Sulphur Dioxide (SO2), Nitrogen dioxides (NO2) and Respirable Suspended Particulate Matter (RSPM/PM10) have been identified for regular monitoring at all the locations. 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 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.


Number of Monitoring Stations

There are 625 operating stations in 263 cities/towns in 29 states and 5 Union Territories of the country. Table given below shows state-wise and city-wise number of operating monitoring stations.


Monitoring Agencies

The monitoring is being carried out by Central Pollution Control Board; State Pollution Control Boards; Pollution Control Committees; National Environmental Engineering Research Institute (NEERI), Nagpur. CPCB co-ordinates with the other agencies to ensure the uniformity, consistency of air quality data and provides technical and financial support to them for operating the monitoring station. N.A.M.P. is being operated through various monitoring agencies, large number of personnel and equipment are involved in the sampling, chemical analyses, data reporting etc. It increases the probability of variation and personnel biases reflecting in the data, hence it is pertinent to mention that these data be treated as indicative rather than absolute.

National Air Quality Monitoring Programme (NAMP)

FINDINGS

The ambient air quality data is available in Environmental Data Bank software (http://www.cpcbedb.nic.in/).

 

Sulphur dioxide

The levels of sulphur dioxide are within the prescribed National Ambient Air Quality Standards.SO2 concentration has decreased over the years indicating that there has been a decline in SO2 levels. Decreasing trend may be due to various interventions that have taken place in recent years such as reduction in sulphur in diesel, use of cleaner fuel such as CNG in metro cities, change in domestic fuel from coal to LPG etc.

 

Nitrogen dioxide

The levels of nitrogen dioxide are within the prescribed National Ambient Air Quality Standards in most of the cities. NO2 concentration has remained stable over the years with a slight decrease in last three years despite increase in sources like vehicles. The reason for this may be various intervention measures that have taken place such as improvement in vehicle technology and other vehicular pollution control measures like alternate fuel etc.

 

Particulate Matter (PM10)

The levels of PM10 exceed the prescribed National Ambient Air Quality Standards in most of the cities. PM10 concentration shows fluctuating trend exceeding the NAAQS. The reasons being emission from gensets, small scale industries, biomass incineration, suspension of traffic dust, natural dust, commercial and domestic use of fuel and vehicular emission etc. Furthermore, the increasing trend for PM10 may be attributed to the increasing number of vehicles and re-suspension of natural dust.

 

Non-attainment Cities

CPCB has identified list of polluted cities in which the prescribed National Ambient Air Quality Standards (NAAQS) are violated. These cities have been identified based on ambient air quality data obtained (2008-2010) under National Air Quality Monitoring Programme (NAMP). Action plans are being formulated and implemented to control air pollution in non-attainment cities by respective states.
