“…The extraction procedure is performed because it enriches the analyte level and lowers the interferences, and it is selected based on the type of pesticide and the nature of the sample to be analyzed [33]. Furthermore, the effectiveness of extraction is influenced by solvent polarity, dispersion coefficient, hydrogen bonding, and the solubility of OCPs in certain solvents [34]. According to the literature [35], the extraction procedure should be characterized by recoveries of at least 80% (lower values are synonymous to erroneous results) to require a small amount of organic solvent and minimum cleanup before quantification.…”

“…Solid-phase microextraction (SPME) was developed during the 1990s and presents superiority over the above-mentioned extraction procedures, as it is solvent-free, with lower detection limits, sensitivity, and good reproducibility, and it has proven its efficiency when coupled with GC techniques [33][34][35]. Moreover, SPME proved its utility for OCP extraction from aqueous samples.…”

Water contamination with organochlorine pesticides (OCPs) is strongly linked to agricultural practices, and it still represents an environmental issue, despite the OCPs bans in many countries and despite the reported sustainable remediation technologies for their removal. Considering the environmental persistence of OCPs, the imbalances produced in the ecosystem, and the bioaccumulation tendency in living organisms through the food chain, the monitoring of OCPs and of their metabolites has crucial importance. The accuracy of the results obtained is strongly connected to the selection of reliable and accurate analytical procedures, especially considering the multitude of challenges related to OCP quantification. The purpose of this paper is to present an overview of the analytical techniques and protocols reported for OCP assessment in water, and to offer scientists a presentation of the current state of the literature on this subject. Nevertheless, it must be considered that each method has advantages and disadvantages, and, in most cases, the protocols reported in the literature must be adapted and improved. In addition, the levels of OCPs identified in surface water, groundwater, and rainwater have been reviewed. This review paper is directly connected to sustainability practices, since environmental sustainability is related to the responsibility to conserve natural resources and to prevent pollution, and for scientists, these objectives are fulfilled by conducting chemical analyses to track and quantify pollutants, as part of environmental studies.
