A rigorous evaluation of environmental contamination requires constant innovation in analytical approaches to gain early identification and accurate quantification of every substance able to compromise health and well-being, particularly when trace analysis of organic and inorganic contaminants, and their species, in complex environmental samples is required. The analytical process comprises several steps; above all, sample treatment, involving isolation of analytes, purification of extracts, and preconcentration often constitute the most time- and labor-consuming part. This review provides an overview of sample treatment procedures applied for the analysis of organic and inorganic compounds in environmental samples in recent years. The current state of the art is emphasized on those techniques and approaches that have already demonstrated their sufficient analytical performance.
