Sampling of atmospheric emissions in Quebec

Sampling of air emissions in Quebec is an important activity for measuring air quality and environmental compliance of stationary sources. It involves taking samples of gases, particles or contaminants from the chimneys, ducts or vents of industrial, commercial or institutional facilities. These samples are then analyzed in a laboratory to determine the concentration and composition of the pollutants emitted.

Sampling atmospheric emissions requires following strict protocols and complying with applicable standards. The Quebec Ministry of the Environment and the Fight against Climate Change (MELCC) publishes "Book 4 - Sampling of Atmospheric Emissions from Stationary Sources", which is part of a series of technical documents that provide guidelines and recommendations for planning and conducting sampling. This booklet describes the following aspects:

• The objectives and principles of atmospheric emissions sampling;
• The types and methods of sampling, depending on the parameters to be measured;
• The equipment and instruments needed to carry out sampling;
• Procedures for calibration, verification and maintenance of equipment and instruments;
• Precautions to be taken to ensure the safety of personnel and the protection of the environment;
• Good practices for handling, storing and transporting samples;
• Items to include in the sampling report.

Sampling of air emissions must be carried out by qualified and experienced persons who have the knowledge and skills required to carry out the operations adequately and reliably.

The MELCC offers an accreditation program for laboratories and organizations that carry out sampling of atmospheric emissions. This program aims to recognize the technical competence of the stakeholders and to ensure the quality and uniformity of the results.

Sampling air emissions is an essential tool for assessing the impact of human activities on air quality and public health. It is used to verify compliance with current standards and regulations, monitor greenhouse gas and air pollutant emissions, and implement mitigation or emission reduction measures. It thus contributes to environmental protection and sustainable development in Quebec.
