CEN/TC 264/WG 31 - Biomonitoring methods with mosses and lichens

CEN/TC 264/WG 31 is a Working Group within the European Committee for Standardization (CEN). It is named "Biomonitoring methods with mosses and lichens" and is responsible for: WG 31 deals with description of a method of survey of population of epiphytic lichens and of determination of a biological index of epiphytic lichens. This index will allow to assess the biological effects of air quality on ecosystems by means of epiphytic lichens, taking into account the micro-environmental conditions. Furthermore, WG 31 deals with description of a method, using in-situ mosses, for assessing the environmental impregnation by organic and non-organic elements. This method has already been widely used. This standard will allow harmonizing the use of the method in order to compare the results. The method can apply to the localization of pollution sources and dispersion areas at local and regional levels. It also allows the mapping of background pollution at national or global levels. This committee has published 2 standards.

The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.

A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
