Özet
In the past several decades, public awareness has increased that environmental contaminants are a health risk. As a result of a requirement for determination of toxic contaminants in air, water, and solids (including soil, sediment and food samples), the interest in environmental research and monitoring has increased. Although highly selective separation and sensitive instrumentation for quantification, the approach of “dilute and shoot” of is not compatible with environmental determinations. An extraction step is necessary for isolation and enrichment trace level analytes from sample matrixes. Classical extraction procedures consume large amounts of solvents, thus they create their environmental and occupational hazards, and often provide very little selectivity. For example, when semivolatile compounds in different matrixes are analyzed by using conventional approaches such as Soxhlet extraction for solid samples liquid-liquid extraction for aqueous matrixes, toxic chemical management and disposal are required. The development of new technologies, such as pressurized liquid extraction (PLE), solid-phase microextraction (SPME), microwave-assisted extraction (MAE) and supercritical fluid extraction (SFE) reduced solvent use. There has been an increasing demand for new techiques, because they are appropriate automation, a lot faster and are environmentally friendly techniques. © 2012, Hacettepe University, Faculty of Pharmacy.
