This method provides information on health hazard likely to arise from exposure to test substance (liquids, solids and aerosols) by application on the eye. This Test Guideline is intended preferably for use with albino rabbit. The test substance is applied in a single dose in the conjunctival sac of one eye of each animal. The other eye, which remains untreated, serves as a control. The initial test uses an animal; the dose level depends on the test substance nature. A confirmatory test should be made if a corrosive effect is not observed in the initial test, the irritant or negative response should be confirmed using up to two additional animals. It is recommended that it be conducted in a sequential manner in one animal at a time, rather than exposing the two additional animals simultaneously. The duration of the observation period should be sufficient to evaluate fully the magnitude and reversibility of the effects observed. The eyes should be examined at 1, 24, 48, and 72 hours after test substance application. The ocular irritation scores should be evaluated in conjunction with the nature and severity of lesions, and their reversibility or lack of reversibility. Use of topical anesthetics and systemic analgesics to avoid or minimize pain and distress in ocular safety testing procedures is described.

Les essais au champ de plantes cultivées ont pour objet de déterminer la quantité de résidus de pesticides présents sur ou dans les produits agricoles bruts, y compris dans les aliments pour animaux. Ils doivent pouvoir mettre en évidence les modes d’utilisation des pesticides qui conduisent à la teneur en résidus maximale. Les essais au champ visent à (1) quantifier la teneur en résidu(s) à laquelle s’attendre après un traitement conforme aux bonnes pratiques agricoles en vigueur ou proposées; (2) déterminer, le cas échéant, le taux de dissipation du ou des résidus de produits phytosanitaires dans les cultures considérées; (3) déterminer des paramètres telles que la « valeur médiane des résidus en essais contrôlés » ou la « valeur de résidu la plus élevée », afin d’évaluer les risques alimentaires; enfin, (4) en déduire les limites maximales de résidus (LMR). La présente ligne directrice pour les essais au champ de plantes cultivées exige un échantillon provenant de parcelles traitées à chaque intervalle d’échantillonnage pour les cultures qui font l’objet de huit essais ou plus. La ou les substances d’essai sont stockées dans des conditions adaptées pendant la durée de l’étude et appliquées rapidement après leur préparation ou leur mélange. La substance d’essai n’est pas appliquée en cas de fort vent, de pluie, ou si des précipitations sont attendues peu après l’application. Pour chaque traitement, le taux d’application est exprimé en quantité de produit et/ou d’ingrédient actif par unité de surface. A la fin de chaque essai au champ de plantes cultivées, les échantillons (entreposés) sont analysés pour mesurer leur teneur en résidu (exprimée par example en mg/kg).

IUCLID (International Uniform Chemical Information Database) is a software application designed to record, store, maintain and exchange data on chemicals. It is a key software application for both regulatory bodies and the chemical industry where it is used in the implementation of various regulatory programmes. IUCLID can be customised and configured to manage chemical data in different contexts and is a platform employing globally harmonised data elements pertinent to chemicals. It is continuously updated to provide greater customisation, extension and integration with other tools. This second edition provides the latest updates on IUCLID features and processes, including visual "working" contexts for the preparation and management of data according to regulatory contexts or data processes, possibilities for data entry in multiple languages, and a matrix view of the use of IUCLID in OECD countries.

The development of plastic products does not systematically take sustainability, particularly from a chemicals perspective, into account. This report seeks to enable the creation of inherently sustainable plastic products by integrating sustainable chemistry thinking in the design process. By applying a chemicals lens during the plastic material selection process, designers and engineers can make informed decisions to incorporate sustainable plastic during the conceptualisation phase of their products. The report provides an integrated approach to sustainable plastic selection from a chemicals perspective, and identifies a set of generalisable sustainable design goals, life cycle considerations and trade-offs. At a more granular level, considerations are identified for each life-cycle phase, which are brought together as a whole-product assessment and optimisation taking the full life cycle into account. The report also considers trade-offs that will need to be carefully balanced in the design phase and reflection on implications of design choices. Ultimately, the report helps to equip designers and engineers with knowledge of relevant chemical considerations when selecting sustainable plastic, supporting better outcomes and a more transparent process.
