    Socio-economic assessment of phthalates - Environment Working Paper

    This paper gives an overview of economic assessments of the benefits of the control of exposure to phthalates, a group of chemicals with numerous uses, most importantly, as a plasticiser to make rigid plastics like PVC flexible. There is significant concern that these substances can act as endocrine disrupting chemicals (EDCs), affecting both human health and ecosystems.

    Economic Valuation in Formaldehyde regulation - Environment Working Paper

    This paper gives an overview of economic assessments of the benefits of the control of formaldehyde and reflects on developments in its risk management and regulation. Formaldehyde is used in the manufacture of resins, as a disinfectant and fixative and as a preservative in consumer products. Formaldehyde exposure can be harmful to human health.

    Council Act: Revision to the "Decision-Recommendation on the Co-operative Investigation and Risk Reduction of Chemicals"

    The Decision-Recommendation on the Co-operative Investigation and Risk Reduction of Chemicals revises and replaces a 1991 Decision-Recommendation of the Council. The Decision-Recommendation is composed of two parts: Part A focuses on the development of harmonised hazard and exposure assessment methodologies for chemicals and Part B focuses on risk prevention and reduction.

    Economic assessment and valuations of environmental and health impacts caused by Perfluorooctanoic acid (PFOA) and its salts - Environment Working Paper

    Perfluorooctanoic acid (PFOA) is being used in fluoropolymer production, as surface treatment agents and for the manufacture of side-chain fluorinated polymers. However, there is evidence that PFOA and its salts have a number of hazardous properties that may cause harm to human health and the environment. This report evaluates existing economic assessments and valuations of impacts arising from PFOA and its salts.

    Exposure Assessment

    Risks to human health and the environment posed by chemicals is determined by the chemical-specific hazard properties and the extent of exposure to chemicals. Read more on the OECD work in developing and harmonising methods for assessing the exposure of chemicals to humans and the environment.

    Safety Assessment of Transgenic Organisms in the Environment, Volume 7 - OECD Consensus Documents

    Volume 7 of the Series compiles the OECD consensus documents for use in environmental risk assessment of transgenic organisms (biosafety) issued in 2016 and 2017. The first two chapters cover the biology of plant species (sorghum and tomato) and include elements of taxonomy, centres of origin, reproductive biology, genetics, outcrossing, crop production and cultivation practices, interactions with other organisms, main pests and pathogens, and biotechnological developments. The third chapter relates to Atlantic salmon, the first OECD biosafety publication to address an animal species. It describes the biology and ecology of wild salmon (including classification, life stages, reproduction, centres of origin, geographical distribution, population dynamics, interaction with other organisms) and of the farmed form (domestication, aquaculture rearing practices, biocontainment, interactions with the external environment). It also provides elements of genetics, research on genetically engineered salmon and resources for its risk assessment.

    BioTrack Product Database

    This OECD database allows regulatory officials and stakeholders to share information on products derived from the use of modern biotechnology, as well as some products with novel traits acquired by the use of conventional breeding or mutagenesis, that have been approved for commercial application in at least one country, in terms of food, feed or environmental safety.

    Test No. 247: Bumblebee, Acute Oral Toxicity Test

    This test guideline is a laboratory test method, designed to assess the acute oral toxicity of pesticides and other chemicals to adult worker bumblebees. Adult worker bumblebees are exposed to 50 % (w/v) aqueous sucrose solution containing the test chemical. 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.

    Test No. 244: Protozoan Activated Sludge Inhibition Test

    This Test Guideline describes a method to assess effects of a test chemical on the phagocytotic activity of activated sludge containing protozoan organisms under defined conditions in the presence of different concentrations of the test chemical. The principle of biological sewage-treatment plants (STP) is to transform the organic matter of incoming waste-water in microbial biomass, which in turn is separated from the liquid yielding a purified effluent. The purpose of the test is to provide a means to record effects of test chemicals on ciliated protozoa in sewage treatment plants, which due to their grazing on bacteria considerably contribute to the functioning of STPs.

    Test No. 318: Dispersion Stability of Nanomaterials in Simulated Environmental Media

    This test guideline describes a test procedure to gain information on dispersion stability of manufactured nanomaterials in simulated environmental media. The main purpose of this guideline is to assess the ability of a nanomaterial to attain a colloidal dispersion and to conserve this dispersion under environmentally relevant conditions. The test procedure involves a dispersion of the nanomaterial with the aid of a calibrated sonication procedure and the determination of the mass concentration of the nanomaterial in a set of test vials while the particles undergo homoagglomeration and settling in environments of different hydrochemistry
