Green Chemistry has emerged in the 1990s as a way that the skills, knowledge, and talents of chemists can be used avoid threats to human health and the environment in all types of chemical processes. One of the most active areas of Green Chemistry research and development is in analytical methodology development. New methods and techniques that reduce and eliminate the use and generation of hazardous substances through all aspects of the chemical analysis lifecycle are the manifestations of the recent interest in Green Analytical Chemistry.
