“…A micro liquid-liquid extraction (MLLE) procedure, which is essentially a simultaneous extraction and concentration procedure suitable for the determination of a wide range of organic trace compounds in water, has been selected for this purpose owing to the great potential of this method. [6][7][8] The principle of MLLE is the extraction of a large volume of water with a very small volume of solvent to give an extract that can be analysed directly without any further treatment. It can be easily performed with basic equipment and low manpower.…”

Miscellaneous pesticides and related compounds include the compounds that can neither be included in the classical chemical category of pesticides nor classified by their class of action. They are a heterogeneous group of substances like macrocyclic lactones, chloronicotinyls, tetranortriterpenoids, ammonium quaternary salts, dinitroanilines, acetamides, oximes, triazoles and pyridine‐based molecules. Their common characteristic is that they are recently developed pesticides. Sample preparations in environmental matrices: air, water, soil, food and biological samples are described. Analytical techniques for characterizing these compounds include gas chromatography (GC), high‐performance liquid chromatography (HPLC), and a wide variety of other emerging techniques such as capillary electrophoresis (CE), supercritical fluid chromatography (SFC), voltammetric and immunoassay techniques. Here, those applied to the field of real samples are presented.

A simple and sensitive method for the determination of 21 polyphenolic compounds in wastewater from olive oil production plants is proposed. The method involves a liquid-liquid microextraction (LLME) procedure with ethyl acetate followed by a silylation step. Identification and quantification have been performed by gas chromatography-mass spectrometry (GC-MS). MS measurements were carried out using selected ion monitoring mode (SIM). alpha-Naftol was used as internal standard. The proposed method was applied to the determination of these compounds in wastewater from an olive oil production factory in Jaén (Spain) at concentration levels ranging from 1.0 to 75.0mugml(-1) for each compound. The autodegradation process by own microbiota in samples collected in three different points of the factory was also studied. The method was validated by a recovery assay with spiked samples.
