There is an increasing use of so-called emerging substances or substances of emerging concern. These terms describe, inter alia, the replacement of commonly used chemicals in formulations by supposedly less harmful chemicals. A well-known example is the shift from DEHP to higher molecular weight phthalates and later the shift from phthalates to DINCH, adipates, terephthalates, etc. Similar trends can be observed in the case of solvents and flame retardants. Over the years, new compound groups such as perfluorocarbons, UV-filters, synthetic musks, parabens, siloxanes, neonicotinoids and drug residues also appeared on the scene. Today, however, the term “emerging substances” has to be defined much more broadly as regards the indoor environment. As a result of the extensive measures for energy-related renovation, contaminated waste products such as asbestos, PCBs, PAHs and PCNs are once again forming the focus of attention as re-emerging chemicals. Many relevant compounds, in particular reaction products, were unknown until recently due to the fact, that they can only now be detected using highly sensitive methods. Furthermore, already known chemicals attract scientific and public interest through reclassification or through the derivation of indoor guideline and reference values.

The classical way of monitoring emerging compounds is air and dust analysis and therefore, the spectrum of analytical techniques needs to be continuously broadened. However, there is also a demand for human biomarkers, preferably in urine. A further important aspect is the post-hoc analysis of house dust and urine samples, which are stored in environmental specimen banks. The identification and temporal tracking of emerging chemicals is thereby enabled. It is strongly recommended to take advantage of the possibilities resulting from the combination of classical interior analytics and human biomonitoring to promptly detect emerging pollutants and chemicals of concern.

越来越多地使用所谓的新兴物质或新兴关注的物质。这些术语尤其描述了用所谓危害较小的化学药品代替制剂中的常用化学药品。一个众所周知的例子是从DEHP转变为较高分子量的邻苯二甲酸酯，然后又从邻苯二甲酸酯转变为DINCH，己二酸酯，对苯二甲酸酯等。在溶剂和阻燃剂的情况下，也可以观察到类似的趋势。多年来，新化合物组如全氟化碳，紫外线过滤剂，合成麝香，对羟基苯甲酸酯，硅氧烷，新烟碱和药物残留物也出现在现场。然而，今天，就室内环境而言，“新兴物质”一词的定义必须更为广泛。由于采取了与能源有关的整修措施，受污染的废品，例如石棉，多氯联苯，多环芳烃和多环芳烃，再次成为新出现的化学药品，成为人们关注的焦点。许多相关的化合物，特别是反应产物，直到最近才被发现，原因是它们只能使用高度灵敏的方法进行检测。此外，已知的化学品通过重新分类或通过导出室内指南和参考值吸引了科学和公众的兴趣。

监测新兴化合物的经典方法是空气和灰尘分析，因此，分析技术的范围需要不断拓宽。然而，还需要人类生物标记物，优选在尿液中。另一个重要方面是对储存在环境标本库中的房屋灰尘和尿液样本进行事后分析。由此实现了对新兴化学物质的识别和时间跟踪。强烈建议充分利用经典室内分析和人类生物监测相结合所带来的可能性，以迅速发现令人关注的新兴污染物和化学物质。
