Odour assessment methods: appropriate uses to obtain the most accurate results

This paper presents a brief summary of the different methods for assessing odours and discusses their advantages and disadvantages. Odour assessment methods are divided into two categories: assessments at potential sources and ambient assessments at affected areas, which are usually residential areas located close to potential odour sources. Despite there being several available methodologies, the emphasis is on the following methods: source odour testing with dynamic olfactometry evaluations and dispersion modelling analysis to predict off-site odour concentrations; ambient sampling with dynamic olfactometry analysis, monitoring of ambient odour concentrations using the Nasal Ranger and the Scentroid SM100. In addition to the brief summaries of each available methodology, seven case studies are also introduced to compare their results when different techniques are used

Summary and overview of the odour regulations worldwide

When it comes to air pollution complaints, odours are often the most significant contributor. Sources of odour emissions range from natural to anthropogenic. Mitigation of odour can be challenging, multifaceted, site-specific, and is often confounded by its complexity-defined by existing (or non-existing) environmental laws, public ordinances, and socio-economic considerations. The objective of this paper is to review and summarise odour legislation in selected European countries (France, Germany, Austria, Hungary, the UK, Spain, the Netherlands, Italy, Belgium), North America (the USA and Canada), and South America (Chile and Colombia), as well as Oceania (Australia and New Zealand) and Asia (Japan, China). Many countries have incorporated odour controls into their legislation. However, odour-related assessment criteria tend to be highly variable between countries, individual states, provinces, and even counties and towns. Legislation ranges from (1) no specific mention in environmental legislation that regulates pollutants which are known to have an odour impact to (2) extensive details about odour source testing, odour dispersion modelling, ambient odour monitoring, (3) setback distances, (4) process operations, and (5) odour control technologies and procedures. Agricultural operations are one specific source of odour emissions in rural and suburban areas and a model example of such complexities. Management of agricultural odour emissions is important because of the dense consolidation of animal feeding operations and the advance of housing development into rural areas. Overall, there is a need for continued survey, review, development, and adjustment of odour legislation that considers sustainable development, environmental stewardship, and socio-economic realities, all of which are amenable to a just, sitespecific, and sector-specific application

Revision de la legislacion sobre olores en varias partes del mundo, un trabajo de 14 expertos internacionales

In this paper we will try to introduce some of the information that a group of 14 experts from different countries is discussing regarding odour regulations. The aim is to publish the first critical review over odour legislation in several parts of the world, analysing not only from a descriptive way any single regulation, but also from a critical point of view. This review will try to identify points to improve and will offer alternatives to some common issues when dealing with regulating the odour impact. The final paper will be published in a Journal not determined yet
