NAMP - Objectives

The following are the objectives of the National Air Quality Monitoring Programme (NAMP):

• To assess the status and trends of ambient air quality;
• To determine if the specified ambient air quality requirements are being violated;
• To determine the Non-Achievement Cities;
• To gain the knowledge and comprehension required to create preventive and remedial procedures;
• To comprehend how the environment is naturally cleansed through pollution generation, dilution, dispersion, wind-based movement, dry deposition, precipitation, and chemical change.

NAMP - Monitoring

• The monitoring of pollutants is done twice a week for a duration of 24 hours (4 hours for gaseous pollutants and 8 hours for particulate matter), resulting in a total of 104 observations in a year.
• The Central Pollution Control Board, State Pollution Control Boards, Pollution Control Committees, and National Environmental Engineering Research Institute (NEERI), Nagpur, are all involved in the process of monitoring.
• The CPCB coordinates with these organizations to guarantee the consistency and uniformity of the data on air quality and offers technical and financial assistance to them so they can run the monitoring stations. Through a number of monitoring agencies, N.A.M.P. is administered.

NAMP - Pollutants Taken

• Four air pollutants have been identified under N.A.M.P. for routine monitoring at all the locations.
• They include sulfur dioxide (SO2), nitrogen oxides (NO), respirable suspended particulate matter (RSPM / PM10), and fine particulate matter (PM2.5).
• Along with the monitoring of air quality, meteorological factors like temperature, relative humidity (RH), wind speed and direction, and RH were also tracked.

NAMP - Current Scenario of Prescribed Pollutants

Sulfur dioxide (SO2)

• Sulfur dioxide concentrations are within allowed limits set by the National Ambient Air Quality Standards.
• Sulfur dioxide levels in residential areas of cities like Delhi, Mumbai, Lucknow, Bhopal, etc., have been on the decline during the past few years.
• It may be on the decline as a result of a number of actions, including the use of LPG in place of coal as a residential fuel and the reduction of sulphur in diesel, among other things.
• Additionally, switching from diesel to CNG may have helped lower ambient SO2 levels.

Nitrogen dioxide (NO2)

• In most cities, the levels of nitrogen dioxide are below the regulated National Ambient Air Quality Standards.
• In the past few years, a decreasing trend in nitrogen dioxide levels has also been noted in residential areas of Bhopal, Solapur, etc.
• Nitrogen dioxide levels may be on the decline as a result of many steps made to reduce vehicular pollution, such as tougher vehicle emission standards, etc.
• One of the main sources of NO2 in the nation is transportation.
• Despite a sharp increase in the number of automobiles, the trend in ambient NO2 fluctuates in many places.

Respirable Suspended Particulate Matter (RSPM)

• In most cities, the levels of RSPM are higher than the permitted National Ambient Air Quality Standards.
• Numerous cities are experiencing an exponential rise in the number of vehicles. This is the only significant contributor to elevated RSPM levels.
• RSPM levels have also been on the decline during the past few years in cities like Solapur, Ahmedabad, etc.
• It might be because of different actions taken, such as reducing the sulphate content of diesel and requiring diesel cars to meet stricter particulate matter standards, etc.
• In many cities, the ambient RSPM trend is erratic.

Suspended Particulate Matter (SPM)

• In most places, SPM levels are higher than the permitted National Ambient Air Quality Standards.
• Vehicles, natural dust, industries including thermal power plants, sugar, cement, etc., the resuspension of dust, trash burning, etc. are some of the sources of SPM.
• In many cities, the yearly average SPM concentration trend is unstable.
• RSPM and SPM concentrations were found to be lower during the monsoon season, probably as a result of moist deposition.
• Wintertime saw higher RSPM levels, probably as a result of lower mixing heights and calmer weather.

How Does the PM get into the Air?

• The term "particulate matter" (PM) refers to a combination of solid and liquid droplets found in the air.
• Some particulate matter, such as dust, smoke, and soot, can be seen with naked eyes, but another particulate matter is too small to be seen without an electron microscope.
• PM can come from a variety of places, including fields, fires, construction sites, and unpaved roads.
• The majority of the particles are produced by complicated chemical reactions involving substances like sulfur dioxide and nitrogen oxides.
• These are the pollutants that come from things like power plants, industry, and cars.
• The following are some examples of natural sources of PM: sea salt, dust (also known as crustal debris), secondary sulphate, pollen, black carbon from wildfires, and volcanic ash.

NAMP - Non-attainment Cities

• In violation of the established National Ambient Air Quality Standards (NAAQS), the CPCB has compiled a list of polluting cities as the non-attainment ones.
• Based on ambient air quality data collected (2008–2010) under the National Air Quality Monitoring Program, these cities have been recognised (NAMP).
• A city with non-attainment air is one where the standards for national ambient air quality were not met.
• States are developing and putting into effective action plans to reduce air pollution in non-attainment cities.

Role of Central Pollution Control Board (CPCB) in Air Quality

• The Central Pollution Control Board's (CPCB) primary responsibilities are outlined in the following manner by the Air (Prevention and Control of Pollution) Act of 1981:
• To offer guidance to the central government on any issue relating to bettering air quality and preventing, controlling, and reducing air pollution.
• To organize and monitor the implementation of a national program aimed at preventing, managing, and reducing air pollution.
• To offer the State Pollution Control Board advice and technical support.
• To conduct and support studies and research on the prevention, regulation, and reduction of air pollution.
• To compile, publish, and gather technical and statistical information about air pollution; and
• To establish and repeal air quality standards.
• The CPCB has the authority to establish standards for air quality thanks to the authority granted to it by the Air (Prevention and Control of Pollution) Act.

NAMP - Challenges

• Upgradation of Network: The development of the current monitoring network is of the utmost importance.
• Regular Monitoring Stations: In accordance with the population, traffic, and industrial densities, regular monitoring stations must be commissioned.
• Additional Online Stations: The establishment of several additional online stations are required to obtain real-time data regarding the spatial distribution of pollution and areas of acute pollution, in accordance with the recommendations made by the Parliamentary committee.
• Information Handling And Distribution: To enable citizens to take preemptive action, information from sensors must be carefully handled and promptly distributed.
• Regional-level Action Plans: Based on precise data gathered from the monitors, policymakers and pollution control authorities must create a city- and region-level action plans to reduce air pollution.
• Otherwise, the entire monitoring process will be unnecessary, making it harder to achieve the mitigation goal and eventually putting citizens at risk for health problems.

Conclusion

Since there is a higher chance that personnel biases and variations will be reflected in the data, it is important to note that these statistics should only be used as a guide rather than as an absolute. Besides, to make decisions for the population's environment and health, NAMP's efficient operation, overall sustainability, and system performance are essential. Data quality is crucial, and the CPCB has implemented a number of steps through its zonal offices. In order to achieve the goals of the overall program, field and laboratory employees are trained, and quality control tests and monitoring station maintenance are also carried out through routine visits and inspections.
