päästömittausta

Päästömittaus, known in English as emissions measurement, is the process of determining the quantity of specific substances released into the atmosphere. This is crucial for environmental monitoring, industrial regulation, and assessing the impact of human activities on air quality. Various types of emissions are measured, including pollutants from vehicles, industrial smokestacks, and even natural sources.

The methodology for päästömittaus varies depending on the source and the substance being measured. For vehicle emissions, standardized tests are conducted on dynamometers to simulate driving conditions. Industrial emissions are often measured using continuous emission monitoring systems (CEMS) installed directly in exhaust ducts, or through periodic grab sampling and laboratory analysis. Common pollutants targeted include particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide, and volatile organic compounds.

Regulatory bodies worldwide set emission limits for different industries and vehicles to protect public health and the environment. Päästömittaus plays a vital role in ensuring compliance with these regulations. It also aids in the development of cleaner technologies and emission control strategies. Accurate and reliable emissions data is essential for understanding pollution trends, identifying pollution sources, and formulating effective environmental policies.
