Abstract In recent years, the testing of nanomaterials during their use in products has been increasingly emphasized, as this will provide a more realistic risk assessment (RA) compared with RA based on pristine nanomaterials. We show that (i) using such an approach for a “realistic” RA is increasing the complexity of the RA, (ii) several testing-aspects render this approach more challenging than the conventional methods, (iii) interpretation of the results becomes difficult, and (iv) the resulting RA may need to be evaluated carefully as it yields improved understanding of the short-term fate of the individual product, but long-term consequences may be neglected.

纳米材料到微塑料：秋千和回旋处

摘要 近年来，纳米材料在产品中使用过程中的测试越来越受到重视，因为与基于原始纳米材料的风险评估（RA）相比，这将提供更现实的风险评估（RA）。我们表明（i）将这种方法用于“现实”的 RA 会增加 RA 的复杂性，（ii）几个测试方面使这种方法比传统方法更具挑战性，（iii）结果的解释变得困难(iv) 可能需要仔细评估由此产生的 RA，因为它可以提高对单个产品的短期命运的理解，但可能会忽略长期后果。
