Wide and abusive applications of fungicides (such as chlorothalonil) in agricultural production have caused various adverse effects on the environment, especially on the soil. Herein, a novel laser desorption VUV single photon postionization mass spectrometry (LDPI-MS) has been firstly applied to the direct and fast detection of chlorothalonil in soil. In the experiment, three different wavelength lasers were used as the ionization sources (SPI at 118 nm, REMPI at 266 nm and 355 nm) and the results showed that only SPI at 118 nm could achieve expected "soft" ionization. The limit of detection in 118 nm ionization was determined to be 0.5 pmol per spot, ca. 1 mg/kg of chlorothalonil in soil. Moreover, no other additives were needed to assistant desorption/evaporation of chlorothalonil from soil samples and the detecting process could be rapidly completed on the basis of a time-saving sample pretreatment. The results demonstrated that LDPI-MS method held a great potential for detecting real natural soil contaminated with chlorothalonil.

“…Due to its highly toxic to aquatic species and marine organisms, signicant cumulative toxicity 3,4 and more toxic and persistent of its main metabolites (4-OH-CTL) in the environment, CTL and its metabolites are considered as a probable human carcinogen by the United States Environmental Protection Agency (USEPA). 12 The most popular approaches for accurate and precise determination of CTL are based on highly sensitive detectors equipped with chromatographic units such as gas chromatography (GC) coupled with mass spectrometry (MS) [13][14][15] or electron capture detectors, 16,17 and HPLC with DAD detection 18 or coupled with MS. 6 However, susceptibility to factors such as pH 8 and matrix components 19 makes CTL a nasty pesticide of poor recovery for sample preparation prior to chromatographic analysis. In addition, the need of specialized persons and high cost limit their application for on-site screening.…”

“…Classical analytical methods for detecting CTN are high performance liquid chromatography (HPLC; Galera, Vidal, & Frenich, 1997), liquid chromatography-mass spectrometry (LC-MS; Chaves, Shea, & Danehower, 2008;Yamamoto et al, 2009), and gas chromatography (Kurz et al, 2008;Vargyas, Walls, Bramstedt, & Eilrich, 2000). These methods require extensive sample preparation and well-trained personnel to operate sophisticated instruments and interpret the results.…”

An immunochromatographic lateral flow strip test using the competitive format was developed for the determination of chlorothalonil (CTN) residues in cucumber. The limit of detection was less than 100 ng/mL by visual assessment and was found to be 91.78 ± 0.17 ng/mL for quantitative detection using a test strip reader. The recoveries of test samples were from 89.26% to 102.02% and the coefficient of variation (%) was less than 4.75%. Parallel analysis of cucumber samples with CTN showed comparable results from the strip test and high performance liquid chromatography. The strip test requires 5-8 min to complete and provides a very useful screening method for the quantitative and qualitative detection of CTN residues in cucumber.
