“…As shown in Table S2, compared to that reported HPLC-DAD methods [4,8,10], our method presents lower LODs. The SPE-HPLC method using MWCNTs as adsorbents showed the lowest LODs [10], however, the pretreatment time of conventional SPE is nearly 4 h while the pretreatment time of MSPE only less than 30 min.…”

“…Analytical performance of the developed MSPE-HPLC-DAD method for the detection of pyrazole/pyrrole pesticides was compared with reported GC or HPLC methods, where SPME [2], DLLME [4] or SPE [8,10] was used for the extraction of pyrazoles/pyrroles pesticides. As shown in Table S2, compared to that reported HPLC-DAD methods [4,8,10], our method presents lower LODs.…”

“…Currently reported pretreatment techniques for pyrazole/pyrrole pesticides from environmental water samples mainly include solid-phase extraction (SPE) [3,[6][7][8], solid phase microextraction (SPME) [2], and dispersive liquid-liquid microextraction (DLLME) [3]. SPE, due to its high recovery, short extraction time, high enrichment factor, low consumption of 4 organic solvents, and ease of automation and operation, has been widely used to concentrate organic compounds in water samples.…”

(relative standard deviation, n=6, %) at three spiked levels were 1.1-5.4% and 3.9-7.8% in terms of peak area, respectively. The method recoveries at three fortified concentration levels ranged from 81.8-107.5% for reservoir water samples, 81.0-99.5% for river water samples, and 80.2-106.5% for seawater samples. The developed MOFs based MSPE coupled with HPLC method proved to be a convenient, rapid and eco-friendly alternative to the sensitive determination of pyrazole/pyrrole pesticides with high repeatability and excellent practical applicability.

“…For ATR, DEA and DIA extraction from environmental water samples, polystyrene-divinylbenzene (PS-DVB)based sorbents with hydrophilic character such as Oasis HLB and Strata-X have been mainly used [45][46][47]48 , but also silica-based 49 , graphitized carbon-based 49 and hypercrosslinked polystyrene-divinylbenzene (HC-PS-DVB) sorbents. 51 CLZ has been successfully extracted with Oasis HLB 49,50 and HC-PS-DVB sorbents. 51,52 Schatz (2012) 53 found that only the HC-PS-DVB sorbents Bakerbond SDB-1 and LiChrolut EN were able to retain DPC.…”

As a renowned s-triazine herbicide, ametryn is worldwide emitted into the atmosphere in both gaseous and particulate phases via spray drifts from treatments and post application emissions, but its chemical degradation in the atmosphere has not been well characterized. In this study, the heterogeneous kinetics of particulate ametryn with NO 3 radicals were investigated with a mixed-phase relative rate method.A vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS) and an atmospheric gas analysis mass spectrometer were synchronously used to online monitor the decays of particulate ametryn and gas-phase isoprene. The reactive uptake coefficient of NO 3 radicals on ametryn particles was calculated to be 2.9 Â 10 À2 , according to the measured ametryn loss ratio and the average NO 3 concentration. The effective rate constant for the heterogeneous reaction of particulate ametryn with NO 3 radicals measured under experimental conditions was 8.4 Â 10 À13 cm 3 molecule À1 s À1. In addition, atraton, ametryn sulfoxide and ametryn sulfone were identified as the reaction products by gaschromatography-mass spectrometry (GC-MS) analysis. The experimental results might shed light on the chemical behavior of atmospheric ametryn at night-time. Environmental impactAmetryn is highly persistent and bio-accumulating in the environment, having a signicant impact on the environment and public health. Therefore, comprehensive knowledge of its behavior in the environment is very important for toxicity and safety assessments. To date, few studies on its chemical degradation in the atmosphere have been performed. In this study, heterogeneous kinetics of particulate ametryn with NO 3 radicals was investigated with a mixed-phase relative rate method, and the reaction products were also determined by GC-MS. The results demonstrated that ametryn could be effectively degraded by NO 3 radicals. This investigation might shed light on the chemical behavior of atmospheric ametryn at night. In addition, the results can provide fundamental data for its health effects in the atmosphere.
