An open framework for automated chemical hazard assessment based on GreenScreen for Safer Chemicals: A proof of concept

0
GreenScreen for Safer Chemicals is a framework for comparative chemical hazard assessment. It is the first transparent, open and publicly accessible framework of its kind, allowing manufacturers and governmental agencies to make informed decisions about the chemicals and substances used in consumer products and buildings. In the GreenScreen benchmarking process, chemical hazards are assessed and classified based on eighteen hazard end‐points from up to thirty different sources. The result is a simple numerical benchmark score and accompanying assessment report that allows users to flag chemicals of concern and identify safer alternatives. Although the screening process is straightforward, aggregating and sorting hazard data is tedious, time‐consuming and prone to human error. In light of these challenges, the present work demonstrates the usage of automation to cull chemical hazard data from publicly available internet resources, assign meta‐data and perform a GreenScreen hazard assessment using the GreenScreen “List Translator.” The automated technique, written as a module in the Python programming language, generates GreenScreen List Translation data for over 3,000 chemicals in about thirty seconds. Discussion of the potential benefits and limitations of automated techniques is provided. By embedding the library into a web‐based graphical user interface, the extensibility of the library is demonstrated. The accompanying source code is made available to the hazard assessment community. This article is protected by copyright. All rights reserved
