澳大利亚工业化学品方案简介(AICIS)承担了7月1日生效,2020年在AICIS,即释放出工业化学品,到澳大利亚商业目的的公司,进口或生产(包括引进)工业化学品,或产品应首先检查是否工业化学品在列出的清单. If the chemical is on the Inventory and the introduction meets the terms of Inventory listing, the introduction is automatically categorized as a “listed” introduction. If the chemical is not listed, it must be categorized into one of five categories. On August 3, 2020, Australia publishedadditional guidance用于引入工业化学品(和释放工业化学品的产品),在纳米级的至少一个外部尺寸。澳大利亚指出,如果化学是在清单所列化学品的纳米形式“,那么它仅仅看作是对我们的库存[]如果纳米形式具有相同的[化学文摘社(CAS)号化学品的散装形式“。该指南的地址是什么在纳米化学;引进是否被免除,报告,或评估;在研究和开发化学品的使用介绍;介绍使用步骤四个通分类导向六个归类;和分类结果。

指导国家纳米意味着合适的婚姻对象cle size range of one to 100 nanometers (nm). The introduction is a “specified class of introduction” if it is of a chemical that:

  • Is introduced as a solid or is in a dispersion; and
  • 颗粒在未结合状态或作为聚集体或附聚物由,其中至少50%(按数目的粒度分布)具有在纳米级的至少一个外部尺寸。

The guidance states that Australia has “an increased level of concern” for specified classes of introductions due to a greater potential for particular hazards or high levels of human or environmental exposure. According to the guidance, Australia’s increased level of concern for chemicals at the nanoscale “is because of uncertainty about the risks of some of these chemicals due to their potentially different properties, such as chemical reactivity, relative to the non-nanoscale forms of the chemicals.” This uncertainty requires either assessment by Australia or increased reporting or recordkeeping requirements. The guidance outlines the additional or different requirements arising from these concerns.
