This test guideline is a laboratory test method, designed to assess the acute contact toxicity of pesticides and other chemicals to adult worker bumblebees.
Adult worker bumblebees are exposed to the test chemical dissolved in an appropriate carrier, by direct application to the dorsal thorax (droplet). The test duration is at least 48 h. Mortality is recorded daily and compared with control values. Results are analysed in order to calculate the LD50 and NOED, if possible, at 24 h & 48 h and furthermore at 72 h & 96 h in case the study is prolonged.
This guidance provides an overarching framework on how to apply available tools to assess the bioavailability of metals in the context of ecological risk assessment.

This short survey aims to gather feedback from a wide range of stakeholders on the OECD Guiding Principles for Chemical Accidents Prevention, Preparedness. The feedback received from this survey will help us making sure the new version is an improvement from the past and that it meets current needs of users.
List of the Council Decisions and Council Recommendations, known collectively as Council Acts, that are relevant to the work of the Chemicals Programme.
Per- and poly-fluorinated alkyl substances (PFASs) are substances that have many manufacturing and industrial applications because they impart useful properties (fire resistance and oil, stain, grease and water repellency). Some of the properties are associated with environmental and human health concerns. To support a global transition towards safer alternatives, this Portal facilitates the exchange of information.
Hazard Assessment of Perfluorooctane Sulfonate (PFOS) and its Salts for human health and the environment, as a result of its investigation in the OECD Existing Chemicals Programme.
The OECD developed the BioTrack Product Database which accommodates Unique Identifiers to each transgenic (or genetically engineered) plant that is approved for commercial use, including planting and food/feed use. These Unique Identifiers are intended to be used as "keys" to access information of each transgenic product in this database and to ensure the safety of modern biotechnology products
The new OECD report on "Economic Features of Chemical Leasing" is a review of the literature on the economic features of the Chemical Leasing, focusing on the drivers and barriers and comparing its functioning to traditional contracts.
The safety of Manufactured Nanomaterials is an important concern impacting regulatory bodies throughout the world. Due to their size, Manufactured Nanomaterials may require additional testing beyond the standard suite of tests used for other chemicals, to ensure that the impact on human health and the environment is fully understood - download Manufactured Nanomaterials Dossiers or search for Tested Endpoints.
