Green Analytical Chemistry guidelines mainly encourage the use of direct and portable methodologies to perform analytical determinations in various areas. However, this target is not possible most cases, it requires a sample pre-treatment. This additional step increases number stages method analysis cost, but also its environmental impact risks operator. Therefore, scientific community currently focused on development novel green treatment methodologies. Thus, an update main novelties found literature about for has been carried out, highlighting those promising with high potential be implemented laboratories future. Moreover, special attention paid evaluation relevance AGREEprep, greenmetric tool specifically dedicated estimation greenness character
