Odor Testing

Sampling and Analysis Services

• Odor surveys for various purposes – business licensing, emission permits, plant expansion, land-use changes, and odor nuisance complaints
• Odor testing in point sources – stacks, vents, and exhaust systems
• Odor testing in area sources –
  • Active sources (e.g., biofilters)
  • Passive sources (e.g., ponds or waste piles)
• Odor testing in volume sources
• Efficiency testing of odor treatment systems
• Odor component testing – hydrogen sulfide, ammonia, mercaptans, TOC, VOC, and more
• Olfactometric odor analysis in a certified laboratory
• Odor dispersion modeling using AERMOD
• Field odor testing by a certified odor panel

Sampling and Testing Process

1. Identification of potential odor sources
2. Preparation and approval of the odor survey plan with the Ministry of Environmental
3. Protection or another relevant authority
4. Field odor sampling
5. Analysis in an accredited olfactometric laboratory
6. Preparation of a detailed sampling report
7. Odor dispersion modeling using AERMOD

Methods and Types of Tests

• Dynamic olfactometry according to EN-13725 standard
• Field odor testing according to Ministry of Environmental Protection guidelines (2019)
• Odor dispersion modeling using AERMOD according to international methodologies
• Odor testing in surface, volumetric, and point sources according to the Odor Nuisance Procedure (2022)
• Testing of inorganic and organic odor components (H₂S, NH₃, VOC, mercaptans, etc.)
• Use of the Ministry of Environmental Protection’s Odor Management Guide (2023)

Frequently Asked Questions

• Why is odor testing important in industrial facilities and sites?
  • To identify odor sources, assess odor intensity and impact, ensure regulatory compliance, and prevent environmental nuisances affecting residents and workers.
• Which standards are used for odor testing?
  • Testing is performed in accordance with EN 13725 using dynamic olfactometry, as well as Ministry of Environmental Protection procedures (2019, 2022, 2023) and ISO 17025 accreditation.
• What does the sampling and analysis process include?
  • Identification of potential odor sources, preparation and approval of a survey plan, field sampling, olfactometric analysis in an accredited laboratory, preparation of a comprehensive report, and odor dispersion modeling using AERMOD.
• What types of odor sources can be tested?
  • Testing can be conducted on point sources (stacks, vents), area sources (ponds, biofilters), volumetric sources, and for efficiency evaluation of odor treatment systems.
• Can specific odor components be analyzed?
  • Yes. Analyses are conducted for substances such as H₂S, NH₃, mercaptans, VOCs, TOC, and additional organic and inorganic compounds.
• What is an olfactometric laboratory and what is its role?
  • An accredited olfactometric laboratory performs odor analysis according to EN 13725 using dedicated equipment and trained professionals to determine odor concentration and regulatory compliance.
• Are field odor surveys also conducted?
  • Yes. The company performs comprehensive field odor surveys, including assessments by a certified odor panel in accordance with the official Ministry of Environmental Protection procedure (2019).
• Is odor dispersion modeling available?
  • Yes. The company performs comprehensive field odor surveys, including assessments by a certified odor panel in accordance with the official Ministry of Environmental Protection procedure (2019).
