    Test No. 509: Crop Field Trial

    Crop field trials are conducted to determine the magnitude of the pesticide residue in or on raw agricultural commodities, including feed items, and should be designed to reflect pesticide use patterns that lead to the highest possible residues.

    Objectives of crop field trials are to: (1) quantify the expected range of residue(s) in crop commodities following treatment according to the proposed or established good agricultural practice; (2) determine, when appropriate, the rate of decline of the residue(s) of plant protection product(s) on commodities of interest; (3) determine residue values such as the “Supervised Trial Median Residue” and “Highest Residue” for conducting dietary risk assessment; and (4) derive maximum residue limits (MRLs).  This Test Guideline requires one sample from treated plots at each sampling interval for crops that have eight or more crop field trials.

    The test substance(s) should be stored under appropriate conditions for the study duration and applied soon after preparation or mixing. Test substance applications should not be made in strong wind, during rain or when rainfall is expected shortly after application. For all applications, the application rate should be expressed in terms of amount of product and/or active ingredient per unit area. At the end of each crop field trial, the (stored) samples are analysed for residue level (expressed for example in mg/kg).

    Test No. 229: Fish Short Term Reproduction Assay

    This Test Guideline describes an in vivo screening assay for fish reproduction where sexually mature male and spawning female fish are held together and exposed to a chemical during a limited part of their life-cycle (21 days). The short term reproduction assay was validated in the fathead minnow (Pimephales promelas) and this is the recommended species. The assay is run with three test chemical concentrations and the necessary controls, including a carrier control if necessary. For the fathead minnow, four replicate test vessels are used for each treatment level and control(s). During the conduct of the assay, the egg production is measured quantitatively daily in each test vessel. At termination of the 21-day exposure period, two biomarker endpoints are measured in males and females separately, as indicators of endocrine activity of the test chemical; these endpoints are vitellogenin and secondary sexual characteristics. Gonads of both sexes are also preserved and histopathology may be evaluated to assess the reproductive fitness of the test animals and to add to the weight of evidence of other endpoints.

    Test No. 302C: Inherent Biodegradability: Modified MITI Test (II)

    This Test Guideline describes the modified MITI test (II). This test permits the measurement of the Biochemical Oxygen Demand (BOD) and the analysis of residual chemicals in order to evaluate the inherent biodegradability of chemical substances which have been found by the Standard MITI Method (I) to be low degradable.

    An automated closed-system oxygen consumption measuring apparatus (BOD-meter) is used. Chemicals to be tested are inoculated in the testing vessels (six bottles with different quantities of test chemical) with micro-organisms. In order to check the activity of the inoculum, the use of control substances (aniline, sodium acetate or sodium benzoate) is desirable. During the test period, the BOD is measured continuously. Biodegradability is calculated on the basis of BOD and supplemental chemical analysis, such as measurement of the dissolved organic carbon concentration, concentration of residual chemicals, etc. The BOD curve is obtained continuously and automatically for 14 to 28 days. After the 14 to 28 days of testing, pH, residual chemicals and intermediates in the testing vessels are analysed.

    Energy Policies of IEA Countries: Portugal 2009

    The International Energy Agency's 2009 review of Portugal's energy policies and programmes.  This edition finds that Portugal has made considerable efforts to strengthen its energy policy since the last IEA in-depth review in 2004. A large number of IEA recommendations have been successfully implemented, including greater diversification of the energy mix and increased energy policy co-ordination. A new National Energy Strategy, published in October 2005, identified three principal means for meeting Portugal’s policy goals: the promotion of renewable energy, increased energy efficiency and competition in energy markets.

    Over a short period of time, Portugal has become a leader in terms of renewable energy development.  Well-designed incentive mechanisms and the adoption of ambitious targets ensure hydro, wind and other technologies will continue to grow. The National Action Plan for Energy Efficiency was enacted in 2008, and Portugal aims to implement energy efficiency measures equivalent to 9.8% of total final energy consumption by 2015. This plan complements a well developed and co-ordinated climate change policy. Further steps have been taken towards the liberalisation of energy markets, including the innovative creation of a single operator for the transport of natural gas and electricity, natural gas storage and operation of the Sines LNG terminal.

    Still, a number of challenges remain. Energy markets are not as competitive as policy makers may have wished, and energy research and development policy coordination needs to be strengthened.

    This review provides sectoral critiques of existing policy and recommendations for further improvements. It is intended to serve as an indispensable guide for Portuguese policy makers as they travel along the path to a more sustainable energy future.

    Measuring Capital - OECD Manual 2009 - Second edition

    Capital - in particular of the physical sort - plays several roles in economic life: it constitutes wealth and it it provides services in production processes. Capital is invested, disinvested and it depreciates and becomes obsolescent and there is a question how to measure all these dimensions of capital in industry and national accounts. This revised Capital Manual is a comprehensive guide to the approaches toward capital measurement. It gives statisticians, researchers and analysts practical advice while providing theoretical background and an overview of the relevant literature. The manual comes in three parts - a first part with a non-technical description with the main concepts and steps involved in measuring capital; a second part directed at implementation and a third part outlining theory and a more complete mathematical formulation of the measurement process.

    Development of Competitive Gas Trading in Continental Europe

    In its latest publication, Development of Competitive Gas Trading in Continental Europe, the IEA examines the history of major gas markets’ development in OECD Europe, and explores the possible expansion of trading through the mechanism of different hubs across the region. Lessons learned from North American markets on the benefits of regulatory convergence and investor-friendly legal framework are an important part of the analysis. Competitive trading based on transparent, non-discriminatory rules in a flexible and integrated European gas market will lead to more efficiency, timely investment, and greater market resilience, therefore ensuring more security for both customers and suppliers in the long term.

    The Future of International Migration to OECD Countries

    This book explores the social, economic and environmental forces that may combine to attract migrants of various types and backgrounds to OECD countries, as well as those that may persuade migrants to leave their countries or to stay at home. By analysing different pull and push factors and constructing five different scenarios of migration in the future, this volume casts light on major determinants of global migration flows, which OECD countries will look particularly attractive for migrants, where the pressures to migrate be especially strong and what kind of migration-related issues will policy makers likely be facing as 2030 approaches.

    OECD Reviews of Innovation Policy: Korea 2009

    This report assesses the current status of Korea’s innovation system and policies, and identifies where and how the government should focus its efforts to improve the country’s innovation capabilities. It finds that Korea has one of the highest rates of spending on R&D in the world, much of which is performed by private firms. It also has a highly educated labour force – as signalled by its impressive PISA performance and exceptionally high rates of tertiary level graduation – with a strong interest in science and technology.

    However, a number of bottlenecks persist that hamper Korea’s economic convergence with the leading OECD economies. These include a relatively weak SME sector and weak performance in services, as well as lagging capacities to conduct leading-edge research in many areas. Furthermore, Korea faces numerous threats in the mid term, notably increased levels of competition from China and other newly-industrialising economies, the lowest fertility rate in the OECD and an ageing society, and a continuing high dependency on imports of natural resources, particularly hydrocarbons. In the shorter term, the economic crisis offers its own challenges, with the need for some policy adjustments to deal with expected falls in business investment in R&D and growing levels of unemployment among the highly skilled.
