The principles of green analytical chemistry

Th e current rapid development of green analytical chemistry (GAC) requires clear, concise guidelines inthe form of GAC principles that will be helpful in greening laboratory practices. Th e existing principles ofgreen chemistry and green engineering need revision for their use in GAC because they do not fully meetthe needs of analytical chemistry.In this article we propose a set of 12 principles consisting of known concepts (i.e. reduction in the use ofreagents and energy, and elimination of waste, risk and hazard) together with some new ideas (i.e. theuse of natural reagents), which will be important for the future of GAC
