Abstract

VARGAS-RODRIGUEZ, Yolanda Marina et al. The flowchart as a traffic light on ecological security of laboratory experiments. Educ. quím [online]. 2016, vol.27, n.1, pp.30-36. ISSN 0187-893X.  https://doi.org/10.1016/j.eq.2015.04.013.

In this paper a comprehensive metric that allows the assess to the greenness of the experiments from the flowchart is presented. The corresponding diagram integrates the treatment and disposal of waste, in addition are considered risks to health, the environment and security using pictograms and safety of reactive rhombuses, auxiliary substances, products and wastes. A letter from 13 colors (from red to green) is also shown in RGB and CMYK systems indicating the number of principles of green chemistry that meets each experiment, and which are used as background color in the diagram components.
