ECHA 如何使用有关用途的信息来评估监管需求？

How is ECHA using information on uses in the assessments of regulatory needs?

ECHA 主要使用 REACH 注册档案（IUCLID）中报告的用途信息（例如生命周期阶段、产品类型、用途描述）作为评估人体暴露和环境释放可能性的指标。对于“广泛”用途，即专业用途、消费者用途以及物品用途，通常认为释放/暴露的可能性很高。对于这些通常发生在许多地方的用途，理论上预期的控制水平被认为是有限的。现阶段不进行定量暴露评估，因此通常不参考化学品安全报告。在某些情况下，也可以使用公共信息。然后将暴露可能性与（潜在）危害一起考虑，以评估对物质（组）的监管需求。

ECHA is mainly using the information on uses (e.g. life cycle stages, type of products, use description) reported in the REACH registration dossiers (IUCLID) as a proxy for assessing the potential for exposure to humans and releases to the environment. The potential for release/exposure is generally considered high for “widespread” uses, i.e. professional and consumer uses and uses in articles. For these uses, normally happening at many places, the expected level of control is, in theory, considered limited. No quantitative exposure assessment is performed at this stage and so the chemical safety reports are normally not consulted. In some cases, public information can also be used. The potential for exposure is then considered together with the (potential) hazard to assess the regulatory needs for the (group of) substance(s).
