Technological Developments in the Determination of Emerging Contaminants in Water

Abstract

Emerging contaminants (ECs), which constitute a group of chemicals, such as personal care products, food additives, and endocrine disruptors, are not commonly monitored and have the potential to cause adverse effects on the environment and humans. In water, even at low concentrations, they pose risks to environmental health. Several technologies have been developed to determine these compounds; the most common ones are liquid-liquid extraction (LLE), solid-phase extraction (SPE), solid-phase microextraction (SPME), stir-bar sorptive extraction (SBSE), and dispersive liquid-liquid microextraction (DLLME) with analysis by gas and liquid chromatography (GC and LC) coupled to mass spectrometry (MS). This chapter analyzes these methodologies and highlights their possibilities and limitations and compiles the most recent advances in this field.
