Measurement and improvement of air quality

This course is part of the programme
Bachelor's programme in Environment (first cycle)

Objectives and competences

The students will familiarize themselves with the impact of gaseous and particulate air pollution on health, which is the underlying reason for the regulation in this field. They will understand the relationships between measurement methods, measured parameters and the regulations. They will get to get to know different in-situ and remote measurement methods and the application of these methods and source apportionment methods to the improvement of air quality. They will carry out measurements during field work and process the data. the seminar will help them to understand the details of aerosol measurements.

Prerequisites

In order to successfully understand the material requires the prior knowledge of some chapters of chemistry, physics, meteorology and mathematics.

Content

  • Gases and particles in the atmosphere
  • Health effects of air pollution
  • Regulation in EU and US, international conventions
  • Measurement methods – in-situ:
    * size distribution
    * absorption
    * scattering
    * mass concentration
    * chemical composition
    * aerosol mass spectrometers

  • Measurement methods – remote detection:

  • LIDAR

  • AOD
  • satelite measurements

  • Source apportionment:

  • CMB

  • PMF
  • Aethalometer model

  • Lowering local air pollution

  • Regional and global aspects of pollution and regulation

Intended learning outcomes

Knowledge and understanding:
Students know how to describe and explain:

  • the impact of air pollution on health,
  • different measurement methods to determine the gas and particle properties in ambient air,
  • different source apportionment methods,
  • the regulations in the EU and US,
  • the importance of local, regional and global effects of air pollution and differences between them.

The students learn about the holistic approach to measurements of air pollution and source apportionment. They know how to plan a simple measurement campaign, apply a source apportionment model and write a report.

Assessment

Written examination (60%), Seminar work (10%), Report from praticals (30%)
