This chapter presents a general overview of the traditional extraction techniques commonly applied to both solid and liquid matrices are evaluated with a view to emphasize their sustained significance in a rapidly changing analytical chemistry discipline as evidenced with the introduction of newer and more sophisticated extraction techniques. For this purpose, the conventional Soxhlet extraction technique for solid matrices and the traditional liquid‐liquid extraction techniques for liquid matrices are critically evaluated. The use of evaporation as a traditional method for extraction and/or separation of target analytes are also considered to further bolster the relevance of this technique in modern analytical chemistry studies. Besides the conventional sample extraction techniques such as Soxhlet extraction (SE), liquid‐liquid extraction (LLE), and mechanical shaking, newer and more sophisticated techniques such as microwave‐assisted extraction (MAE), accelerated solvent extraction (ASE), also known as pressurized liquid extraction (PLE), and supercritical fluid extraction (SFE), have been developed.

Polychlorinated biphenyl (PCB) concentrations in surface soil samples (0-10 cm) from 23 city parks (8 urban and 15 suburban) from Xi'an, China were presented. The average concentration of Σ7 PCBs among all the sites was 1.68 ng g(-1) dry weight. High detection frequency (100 %) of PCB 28 and PCB 52 suggested wide occurrence of PCB contaminations in Xi'an. Among these PCBs, PCB 28, 52 and 153 were the most dominant compounds (14.9 %, 39.3 % and 9.5 % of the Σ7 PCBs on average, respectively). "Urban fractionation effect" was found in Xi'An. In other words, PCB concentrations were higher in the urban city park soils than those in suburban park soils. The PCB contamination in Xi'an city park soils were at a low level based on the Dutch guideline. However, dioxin-like PCB congeners were detected from 12 parks, which indicated further investigation was urgently required in future. Furthermore, total PCB concentrations were used to evaluate the cancer risk via ingestion, dermal and inhalation and the results showed that the total cancer risk was at the very low level in this area.
