Ambient Air Quality Monitoring & Testing - Perfect Pollucon Services (2023)

Ambient Air Quality monitoring or Testing is a processof measurement of pollutants present in the atmosphere. It measuresthe healthiness and safety of our environment.

What is Ambient Air Quality?

Ambient air quality is defined as the quality of air outside and sometimes inside. Ambient air quality standards are limits to concentrations of pollutants in air stated for well being of human, nature, animals, etc. There is no single specified definition of standards resulting, Various organizations use standards which are not often similar. Ambient air quality monitoring is also called as Outdoor Air Quality Testing.

What is Air Quality Monitoring?

Air quality monitoring is the process of assessment of pollutants present in the atmosphere by their quantity and types as per air quality standards. Air quality monitoring helps us to take action based on pollutants present in atmosphere to improve air quality

Why Ambient Air Quality Monitoring or Testing Required?

Air Pollution is the introduction of Chemicals, Particulates orother Harmful materials into atmosphere causes/damage to living organism/BuiltOrganism. Air pollutants are added in the atmosphere from a variety of sourcesthat change the composition of the atmosphere and affect the biotic environment.The concentration of air pollutants depends not only on the quantities that areemitted from air pollution sources but also on the ability of the atmosphere toeither absorb or dispersethese emissions. The sources of air pollutantsinclude vehicles, industries, domestic sources and natural sources. Because ofthe presence of a high amount of air pollutants in the ambient air, the health ofthe population an

property is getting adversely affected. In order to arrestthe deterioration in air quality, Govt. of India has enacted the Air (Preventionand Control of Pollution) Act in 1981. The responsibility has been further emphasized under the Environment (Protection) Act, 1986.Therefore, the Central Pollution Control Board had startedNational Ambient Air Quality Monitoring (NAAQM) Network during 1984 – 85 at the national level. The program was later renamed as National Air Quality Monitoring Program (NAMP).

Ambient Air Quality Monitoring & Testing Methodology

Ambient Air Quality Monitoring & Testing - Perfect Pollucon Services (2)

Ambient air quality monitoring & testing is required to determine the existing quality of air, evaluation of the effectiveness of the control program. National Air Quality Monitoring Program is described in this chapter along with details on pollutants measured and their frequency. Similarly, Guidelines for monitoring are made for carrying out AAQM under NAMP and description of the program is essential as the monitoring is carried out to meet the objectives of NAMP.

Various types of equipment are used to find the amount of Air pollution done by a particular source called ‘’Air Monitoring Equipment.’’Evaluation of Ambient Air for determination of community air Quality as related to local health, Social& EnvironmentalEffects.Determination of suspended particulate matter as small as one-micron size & any four gaseous contaminants at a time.

Ambient Air Quality Monitoring or Testing Parameters

Under N.A.M.P., 12 air pollutants viz., Sulphur Dioxide (SO2), Oxides of Nitrogen as NO2 and Particulate Matter (PM10) and Particulate Matter (PM2.5), Ozone (O3), Lead (Pb), Carbon Monoxide (CO), Ammonia (Nh3), Benzene (C6H6), Benzo-Pyrene (BaP), Arsenic (As), Nikhel (Ni) have been identified for regular monitoring at required the locations/ Industrial unit.

Among all these parameters Particulate matter is the most important pollutant present in the atmosphere. It is also called as Particulate matter Monitoring or Dust Monitoring.
As per CPCB Notification under National ambient air quality testing standards (NAAQS). These Results can beconverted into the non-Technical way so that everybody can understand the level of pollution. it is called as Air Quality Index (AQI).

Ambient Air Quality Monitoring or Testing Standards

Below mentioned are National Ambient or Outdoor air quality standards(NAAQS Standards) which are used in ambient air testing.

ParametersUnitLimit
Sulphur Dioxide (SO2)mg/M3≤ 80
Oxides of Nitrogenmg/M3≤ 80
Particulate Matter PM10mg/M3≤ 100
Particulate Matter PM2.5mg/M3≤ 60
Ozone (O3)mg/M3≤ 180
Lead (Pb)mg/M3≤ 1.0
Carbon Monoxide (CO)mg/M3≤ 04
Ammonia (NH3)mg/M3≤ 400
Benzene (C6H6)mg/M3≤ 05
Benzo(a)Pyrene (BaP)mg/M3≤ 01
Arsenic (As)mg/M3≤ 06
Nickel (Ni)mg/M3≤ 20

Ambient Air Quality Testing Procedure – Duration and Frequency

The period and frequency of ambient or outdoor air quality sampling procedure should be such that statistically reliable averages can be obtained with the data i.e. 8 Hrs or 24 Hrs. National Ambient Air Quality Standards (NAAQS) states that it should be 8 Hrs monitoring or 24 Hrs as per requirement. Particulate matter levels are lower during the monsoon months due to removal by wet deposition. Air pollutants suchas CO levels are higher during winter months due to lower mixing heights resulting in less volume of troposphere available for mixing and hence higher concentrations. Thus measurements should be conducted in all the seasons so that in annual average all the seasons are represented equally. In general, a minimum of 20% of the reading should be taken in each season.

Ambient Air Quality Monitoring Equipment

There are many types of instruments available to monitor ambient air quality such as Respirable dust samplers, High volume air samplers, Handy dust samplers, Combined dust samplers, Portable air quality analyzers, etc. Below are the few Ambient Air Quality Monitoring instruments commonly used in the industry

How is ambient air quality measured?

The process of Air quality measuring is combining multiple pollutants levels present in the atmosphere and then combining their reading with their weightage assigned by pollution control boards. This gives information on air quality to the public whether air quality is either good, moderate, or hazardous.
