There is a large variety of activities in workplaces that can lead to emission of substances. Coding systems based on determinants of emission have so far not been developed. In this paper, a system of Activity Classes and Activity Subclasses is proposed for categorizing activities involving chemical use. Activity Classes share their so-called 'emission generation mechanisms' and physical state of the product handled and the underlying determinants of emission. A number of (industrial) stakeholders actively participated in testing and fine-tuning the system. With the help of these stakeholders, it was found to be relatively easy to allocate a large number of activities to the Activity Classes and Activity Subclasses. The system facilitates a more structured classification of activities in exposure databases, a structured analysis of the analogy of exposure activities, and a transparent quantification of the activity emission potential in (new) exposure assessment models. The first use of the system is in the Advanced REACH Tool.
工作场所存在各种各样会导致物质排放的活动。到目前为止，尚未开发出基于排放决定因素的编码系统。本文提出了一个活动类别和活动子类别的系统，用于对涉及化学品使用的活动进行分类。活动类别共享其所谓的“排放产生机制”、所处理产品的物理状态以及潜在的排放决定因素。一些（行业）利益相关者积极参与了该系统的测试和微调。在这些利益相关者的帮助下，发现将大量活动分配到活动类别和活动子类别相对容易。该系统有助于在暴露数据库中对活动进行更结构化的分类，对暴露活动的相似性进行结构化分析，并在（新的）暴露评估模型中对活动排放潜力进行透明量化。该系统的首次应用是在高级REACH工具中。
