“…In recent years, many pretreatment techniques have been used such as dispersive liquid-liquid microextraction (DLLME) (You et al 2013), solid-phase extraction (SPE) (Xie et al 2013), supercritical fluid extraction (SFE) (Cuong et al 2012), solid-phase microextraction (SPME) (Saraji et al 2013), matrix solid-phase dispersion extraction (MSPDE) (Guan et al 2011), and stir bar sorptive extraction (SBSE) (Yu and Hu 2009). Among them, SPE is the most widely used and commercialized technique because it is simple, stable, and easily automated (Zhao et al 2014).…”

In this study, a molecularly imprinted polymer that can selectively recognize dimethoate, isocarbophos, and methyl parathion was synthesized. Using this compound as sorbent, a new method for simultaneous determination of the three organophosphorus pesticides by molecularly imprinted solid-phase extraction coupled with high-performance liquid chromatography was established. The factors affecting the preconcentration and sensitivity were studied in detail. Under optimal conditions, the limits of detection of this method for dimethoate, isocarbophos, and methyl parathion were 19.78, 8.73, and 17.41 μg/kg, respectively. The relative standard deviation for five replicates of 0.01 mg/L-mixed solutions was in the range of 1.8-4.2 %. Cucumber sample spiked with the three organophosphorus pesticides at levels of 0.125 and 0.250 μg/g were examined using this method, good recoveries were obtained ranging from 82.5 to 95.6 %. Moreover, this method was also successfully used for the detection of the three organophosphorus pesticides in cauliflower sample.

“…Gas chromatography-mass spectrometry (GC-MS) has both the characteristics of high separation efficiency of GC and accurate identification of compounds structure of mass spectrometry. Many studies on pesticide detection by GC-MS quantitatively and qualitatively have been reported (Pinheiro et al 2011;Xie et al 2013). In addition, there are methods applied to the detection of the varieties of pesticides, such as fluorescence spectrometry, immunoassay (Xu et al 2011), capillary electrophoresis (Schmitt et al 1995).…”

Although the low concentration level of pesticides does not have significant impact on the overall water environment, water would become worse due to the pollution accumulation in long-term. The method disclosed in this study can be used as a good example for pesticide detection with the help of microalgae. Raman microspectroscopy technology is a convenient and rapid tool to detect the characteristics of microalgae and contribute for pesticide detection.
