Лабораторний аналіз викидів пересувних джерел, таких як автомобілі, поїзди, літаки та інші транспортні засоби, is an important tool for assessing their impact on atmospheric air quality and public health. This analysis allows you to determine the amount and composition of pollutants, that are released into the atmosphere, and compare them with established standards.

The purpose of laboratory analysis of emissions from mobile sources:

• Assessment of the level of atmospheric pollution: Determination of the contribution of mobile sources to general atmospheric air pollution.
• Control over compliance with standards: Verification of conformity of vehicles emissions set environmental standards.
• Identification of pollutants: Determining a particular composition of emissions, including harmful substances, such as nitrogen oxides, Carbon monoxide, Hydrocarbons, solid particles and other.
• Developing measures to reduce emissions: Justifying the need and choosing effective methods of reducing the negative impact of transportation on the environment.

Methods of laboratory analysis of mobile sources emissions:

Different methods are used to analyze mobile sources emissions, in particular:

• Gasochromatography: Method, that allows you to divide and identify various gaseous emissions components.
• Mass spectrometry: Method, that is used to determine the molecular mass of substances and identify the components of a complex mixture.
• Optical methods: Methods, based on measuring the absorption or scattering of light with substances, emissions contained.
• Electrochemical methods: Methods, based on measuring electric current or potential, occurring as a result of a reaction between pollutants and an electrode.

Laboratory procedure for mobile sources emissions:

1. Selection of samples: Emissions samples are selected with the help of special equipment, which provides gases or particles from the exhaust system of the vehicle.
2. Preparation of samples: Selected samples may need pre -processing, such as breeding, filtration or concentration, To ensure their compatibility with used methods of analysis.
3. Analysis: Laboratory analysis is performed using appropriate methods and equipment to determine the quantitative and qualitative composition of emissions.
4. Processing and interpretation of results: The results obtained are processed and compared with the standards set. On the basis of this, the conclusion is made on the conformity of the vehicle emissions to environmental standards.

Requirements for laboratories, conducting an analysis of mobile sources emissions:

Laboratories, performed by the analysis of mobile sources emissions, must have appropriate accreditation, modern equipment and qualified personnel. It is important to ensure the reliability and accuracy of research results.

Legislative regulation:

Laboratory analysis of emissions from mobile sources is carried out in accordance with the requirements of current legislation in the field of atmospheric air protection and environmental safety.

The importance of laboratory analysis of emissions from mobile sources:

Laboratory analysis of emissions from mobile sources is a necessary tool for ensuring environmental safety and public health protection. Research results are the basis for decision-making regarding the regulation of transport activities, development of measures to reduce the negative impact of transport on the environment and ensure sustainable development of the transport system.
