Description:
Analytical methods capable of trace measurement of semi-volatile organic compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a result of long-range and regional atmospheric transport and deposition. The following study compares the results of two methods, one using pressurized liquid extraction (PLE), and the other using matrix solid phase dispersion (MSPD), for the trace measurement of over 70 SOCs belonging to 10 chemical classes, including current-use pesticides, in tadpole tissue. The MSPD method resulted in improved analyte recoveries and precision of most SOCs compared to the PLE method. The MSPD method also required less time, solvent consumption, and was able to detect a larger number of SOCs than the PLE method.
