Green chemistry promotes improved syntheses as an intellectual endeavour that can have a great impact both on preserving and utilizing our planet’s finite resources and the quality of human life. This masterful accomplishment provides an evaluation of environmental impact metrics according to life cycle assessment analysis based on the Mackay compartment environmental model and Guinée environmental impact potentials formalism. Assumptions, limitations, and dealing with missing data are addressed. Best literature resources for finding key toxicological parameters are provided and applied to individual reactions as well as entire synthesis plans, in order to target molecules of interest. Key Features: Provides an evaluation of environmental impact metrics according to life cycle assessment analysis Summarises safety-hazard metrics according to the same model as life cycle assessment including occupational exposure limits, risk phrases, flammability, and other physical parameters The book will be useful in a range of chemistry courses, from undergraduate to advanced graduate courses, whether based in lectures, tutorials or laboratory experiments
