Air Quality: Determination of Settled Dust and Measurement Methods

TS 2342: Imission (Environmental Air) - Determination of Precipitated Dust - Gravimetric Method

TS 2342: Emission (Ambient Air) - Determination of Settled Dust

TS 2342 is a Turkish standard that defines gravimetric measurement methods used to determine the amount of settled dust in ambient air. This standard is used for monitoring air pollution sources and assessing their environmental impact. Determination of settled dust is an important parameter in the assessment of air quality in industrial zones, urban centers and rural areas.

Standard Scope and Purpose

TS 2342 describes in detail the gravimetric method for determining the amount of settled dust. The main objective is to measure and evaluate the effects of particulate matter (dust) emitted into the atmosphere on the environment. The standard serves the following objectives:

Monitoring Air Pollution: Determination of particulate matter load.
Source Identification: Assessing the effects of industrial and other anthropogenic pollution sources.
Environmental Management: Providing data for the management and improvement of air quality.

What is settled dust?

Settled dust refers to particles that settle to the ground after being dispersed into the atmosphere under the influence of gravity. These dusts are usually

Industrial activities,
Construction activities,
Traffic emissions,
Caused by natural sources (e.g. wind erosion).

What is the Gravimetric Method?

The gravimetric method is a laboratory analysis method for determining the weight of settled dust. Samples are collected over a period of time and weighed in the laboratory to calculate the amount of settled dust. This method provides a simple and precise analysis.

Sampling Process

1. Sampling Devices

Settling Dust Containers: Special containers placed in a specific area to collect dust in the atmosphere.
Standardized Collection Area: Dust containers are placed at specific heights (usually 1.5-2 meters) and in open areas.

2. Sampling Time

Samples are usually collected over a period of 30 days. This time allows a more accurate assessment of atmospheric conditions and the amount of particulate matter.

3. Sampling Points

Factors to be considered in the selection of sampling points:

Distance to the targeted pollution source.
Effect of wind direction and speed.
Other potential pollutants in the area.

Application Areas of Settling Dust Determination

Industrial Zones: Monitoring the impact of factory emissions on the environment.
Urban Areas: Assessment of air pollution from traffic density and construction activities.
Rural Areas: Identification of natural dust sources.
Environmental Impact Assessment: Analyzing the potential impacts of a new facility on the environment.
