“…OPPs are regarded as less persistent in the environment than organochlorine pesticides (OCPs) (Ferrando et al, 1992), and this family of chemicals is one of the substitutes for OCPs, which was banned for use in the 1970s (Vonderheide et al, 2003). It is well known that OPPs have genotoxicity (Cakir and Sarikaya, 2005), cytotoxicity (Giordano et al, 2007), reproductive toxicity (Pina-Guzman et al, 2005), and irreversible inhibitory activity to acetylcholinesterase (Jauregui et al, 2003).…”

“…Element specific detection of 31 P with ICP-MS was used for the determination of these phosphorus-containing pesticides. The difficulties of detecting phosphorus at trace levels by ICP-MS are already known and are related to the high ionization potential of this element and hence low ionization efficiency in an argon-sustained plasma [29,30] ) can interfere at m/z 31, especially when a regular quadrupole (with low mass resolution) is used. Despite these limitations the successful use of a quadrupole ICP-MS system for phosphorus determination has been reported [31].…”

In this work, the potential of inductively coupled plasma-mass spectrometry (ICP-MS) coupled to capillary electrophoresis (CE) to determine organophosphorus pesticides (OPPs) is demonstrated. Element specific detection of (31)P with ICP-MS is performed for the detection of OPPs. Three common OPPs, including glyphosate, glufosinate, and aminomethylphosphonic acid (AMPA), were analyzed by CE-ICP-MS to demonstrate its applicability for the analysis of OPPs. The advantages of using ICP-MS with respect to other common detectors, such as flame photometric detection (FPD), for CE analysis of OPPs are shown. Additionally, different CE separation conditions were studied to achieve complete baseline separation of the pesticide compounds in short migration times. Two CE buffer systems were evaluated for the separation of OPPs using ICP-MS detection. A buffer solution containing 40 mmol.L(-1) ammonium acetate at pH 9.0 and an applied voltage of +20 kV were finally selected leading to a separation time of 10.0 min. Both migration time and area relative standard deviations (%RSD) were evaluated and their respective values were in the intervals of 1.1-3.3% and 2.7-5.3%. Detection limits obtained with the CE-ICP-MS system were in the range of 0.11-0.19 mg.L(-1) (as compound) yielding an enhancement of 130- to 230-fold with respect to FPD. The proposed methodology was finally applied for the determination of the OPPs mentioned above in natural river water samples.

“…Historically, phosphorus has been recognized as one of the elements difficult to analyze in argon plasma. This is due to poor ionization because of its relatively high first ionization potential and because of isobaric interferences such as 15 [24]. However, proper optimization of ICP-MS parameters and high-resolution MS or collision/reaction cells are ways polyatomic interferences can be minimized or eliminated.…”

Inductively coupled plasma-MS (ICP-MS) and its combined use with molecular mass spectrometric techniques have become the most promising detection techniques in speciation studies. High sensitivity and element specificity of ICP-MS has the advantage of detecting trace amounts of the species of interest in complex matrices. This review is divided into two parts. In the first part, suitable use of ICP-MS either online or offline with currently used separation techniques such as HPLC, CE, and gel electrophoresis in speciation analysis is briefly discussed. In the second part, recent applications (1999-2005) of phosphorus speciation is presented to elucidate the importance of ICP-MS in separation methods and to illustrate its importance in nonmetal detection.
