Concern for the natural environment increasingly devotes more attention to growing potential hazards resulting from the release of various substances. Currently, one of the main problems associated with environmental pollution is the derivation of organic compounds from wastewater. Substances derived from sewage leaks into the environment in the form of a multicomponent mixtures often enhances the toxic effects caused by these compounds. While analyzing the reports in the literature of the last two decades it can be seen that substantial efforts are devoted to the determination of selected trace contaminants present in wastewater. Among the most marked there are endocrine disrupting compounds, residues of pharmaceuticals and personal care products, plastics and sunscreens. Recently, a new group of compounds joined the aforementioned contaminants, namely drugs, whose legality and availability is increasing every year. Exposure to these type of compounds, named in the literature as emerging contaminants (ECs), involves, among others, such effects as hormonal imbalance, reduction of the survivability of aquatic organisms and reproductive problems. This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the natural environment in many countries all around the world.

Spreading sewage sludge on agricultural lands has been actively promoted by national authorities as an economic way of recycling. However, as by-product of wastewater treatment, sewage sludge may contain toxic substances, which could be incorporated into agricultural products or be distributed in the environment. Moreover, sediments can be contaminated by the discharge of wastewater effluents into rivers. This article reviews the determination of emerging contaminants (surfactants, flame retardants, pharmaceuticals and personal care products) in environmental solid samples (sludge, soil and sediment). Sample preparation, including extraction and clean-up, as well as the subsequent instrumental determination of contaminants are discussed. Recent applications of extraction techniques, such as Soxhlet extraction, ultrasound assisted extraction, pressurised liquid extraction, microwave assisted extraction and matrix solid-phase dispersion to the analysis of emerging contaminants in environmental solid samples are reviewed. Determination of these contaminants, generally carried out by gas chromatography and liquid chromatography coupled with different detectors, especially mass spectrometry for the identification and quantification of residues, is also summarised and discussed.
