A practical guide to odour sampling methods, explaining how emissions are collected from different sources, including ducts, stacks, biofilters and site boundaries, and how to select the right approach for each assessment.
At Silsoe Odours, we can objectively measure, assess and analyse odours in line with international odour measurement standards. In this article, we explore how to measure odour, with a particular focus on the odour measurement equipment used for both sampling and testing.
Odour monitoring helps operators prevent nuisance, maintain permit compliance, and support planning applications. Explore methods and services for effective odour management.
Odour control is essential for reducing emissions and maintaining compliance. Learn practical odour control methods to prevent complaints and manage industrial odour.
Managing odour is a key responsibility for UK regulated industries. This guide explains how to comply with environmental permits, implement best available techniques, monitor emissions and build an effective odour management plan.
Silsoe Odours has helped shape odour science in Europe for decades. Our Director, Robert Sneath, helped develop EN 13725:2022, the European standard for odour measurement. This blog explains what the standard covers, why it matters, and how UKAS-accredited testing ensures reliable results.
Planning near landfills, wastewater sites, or industrial facilities? Odour can be a hidden risk that affects approvals, property values, and long-term asset performance. This guide explains when an odour impact assessment is needed, your responsibilities under the “agent of change” principle, and key UK regulations and guidance to help developers mitigate odour risks from the earliest planning stages.
Learn how to understand, handle, and prevent odour complaints at industrial sites. Tips for odour monitoring, complaint management, and maintaining community trust.
A practical guide to seasonal odour management for regulated sites. Learn how to plan, monitor, and control odours year-round while staying compliant and protecting community relations.
Hedonic tone odour assessments measure how pleasant or unpleasant an odour is perceived to be. Learn how the hedonic tone scale helps organisations understand odour perception and potential community impact.
Biofilter odour sampling helps assess the performance of biofilters used to treat industrial emissions. Learn how the sheet cover method enables representative odour sampling from large surface areas and supports compliance with EN 13725:2022.
Stack sampling measures odour emissions directly from stacks, flues and vents. It provides reliable data for compliance, planning and odour assessment.
A sniff survey is a structured field method used to assess odour impact in real-world conditions by measuring how odours are experienced off-site.
Odour characterisation training ensures consistent and repeatable odour descriptions across laboratory and field assessments. This improves the reliability of odour interpretation and supports more robust assessment and complaint evaluation.
Understand the agent of change principle and how it affects odour risk in UK planning applications. Includes developer responsibilities and typical mitigation approaches.
Olfactometry is the standard laboratory method used to measure odour concentration and intensity in air samples. This guide explains how dynamic olfactometry works under BS EN 13725:2022, including UKAS-accredited odour sampling and analysis.
UKAS-accredited odour testing laboratory providing sampling and analysis services to support planning, permitting and environmental compliance.
UKAS accreditation and independent proficiency testing ensure reliable odour measurement. Discover the role of BS EN 13725:2022 and olfactometry in delivering consistent, defensible laboratory results for regulatory and technical decision-making.
