Micro-organisms play a fundamental role in the environment. Yet their role is the result of complex biogeochemical processes by consortia of micro-organisms and the function of individual species is not clear in many cases.
This publication provides an overview of the current situation and relevant developments in environmental microbiology, as well as its potential application, which covers: use of micro-organisms for agriculture, production purposes, bioremediation, and cleaning purpose; environmental applications of microbial symbionts of insects; and environmental risk/safety assessment of the deliberate release of engineered micro-organisms.
An addendum to the OECD Guiding Principles on Chemical Accident Prevention, Preparedness and Response to address Natural Hazards Triggering Technological Accidents (Natech) Risk Management has just been published. The addendum consists of a number of amendments to the Guiding Principles and the addition of a new Chapter to provide more detailed guidance on Natech prevention, preparedness and response.
This page explains the background to the OECD Test Guidelines, the reason for their development, their applicability and how they can be accessed.
The objective of these Guiding Principles is to set out general guidance for the safe planning, construction, management, operation and review of safety performance of hazardous installation in order to prevent accidents involving hazardous substances and, recognising that such accidents may nonetheless occur, to mitigate adverse effects through effective land-use planning and emergency preparedness and response.
The peer review process can lead to changes in the interpretation of the slides and the reported results, and potentially the outcome and conclusions of the study. The purpose of this document is to provide guidance to pathologists, test facility management, study directors and quality assurance personnel on how the peer review of histopathology should be planned, managed, documented and reported in order to meet GLP expectations and requirements. This document is a complement to the guidance provided in section 184.108.40.206 of OECD Guidance Document 116 (series on testing and assessment), whose focus is on how histopathology peer review should be conducted.
Ecosystem accounting is a relatively new and emerging field dealing with integrating complex biophysical data, tracking changes in ecosystems and linking those changes to economic and other human activity. Considering the increasing demand for statistics on ecosystems within analytical and policy frameworks on environmental sustainability, human well-being and economic growth and development, there has been an increasing urgency to advance this emerging field of statistics.
Although considerable experience exists in related areas of statistics such as land cover and land use statistics, the integration of these and other information into an ecosystem accounting framework is new. Also, there is considerable existing expertise in the ecosystem sciences and economics fields that is relevant, and again it is the focussing of these different areas of expertise on the proposed ecosystem accounting approach that is new.
SEEA-Experimental Ecosystem Accounting provides a synthesis of the current knowledge in this area and provides a starting point for the development of ecosystem accounting at national and sub-national levels. It represents an important step forward on ecosystem accounting, providing a common set of terms, concepts, accounting principles and classifications; an integrated accounting structure of ecosystem services and ecosystem condition in both physical and monetary terms; and the recognition of spatial areas as forming the basic focus for measurement.

This brochure provides an overview of the OECD work on economy-environment modelling.
This guidance is intended to harmonise the way non-guideline in vitro test methods are described. This should in future facilitate an assessment of the relevance of test methods for biological activities and responses of interest, of the quality of data produced, irrespective of whether these tests are based on manual protocols or assay protocols adapted for use on automated platforms or high-throughput screening systems (HTS).
In today’s hard times, policy-makers can find it difficult to sell their environmental policies. To many, these policies represent a burden on the economy.
Personal behaviour and choices in daily life, from what we eat to how we get to work or heat our homes, have a significant – and growing – effect on the environment. But why are some households greener than others? And what factors motivate green household choices? Answering these questions is vital for helping governments design and target policies that promote "greener" behaviour.
