“…The mean (range) concentration of ∑NEOs in PRE was 33.9 (19.6−104) ng/L. The DFs and concentrations of NEOs found in PRE by this study were much higher than those observed in the Yangtze River Estuary (range = ND−12.45 ng/ L, mean = 3.50 ng/L) 34 and the mouth of Jiaozhou Bay (range = ND−0.38 ng/L, mean = 0.17 ng/L) in China. 35 Previous studies have reported that regional differences in pesticide use in China increase from north to south China.…”

“…Currently, there is a scarcity of global studies that focus on investigating NEOs in seawater. 4,34,35,41 In this study, the concentrations of ∑NEOs found in SS_XS (range = 19.4− 72.8 ng/L, mean = 27.0 ng/L) and in SS_NW (45.2−96.2 ng/ L, mean = 49.9 ng/L) of the South China Sea were much higher than those in the Bohai Sea (range = 0.23−4.70 ng/L) and Jiaozhou Bay (≤LOD−11.19 ng/L) of northeast China. 4,35 Similarly, it was observed that the concentration of ∑NEOs in this study exceeded those sites measured at the East China Sea (ND−0.38 ng/L).…”

This study investigated the residual levels of eight parent neonicotinoid insecticides (p-NEOs) and three NEO metabolites (m-NEOs) in surface waters of river−estuary−ocean systems on a large geographical scale in South China. Imidacloprid, thiamethoxam, acetamiprid, and clothianidin were dominant NEOs in surface waters. High levels of ∑NEOs were found in the upper reaches of Guangzhou section of the Pearl River (PR_GZ), indicating multiple input sources of NEOs in PR_GZ. Additionally, the decreased influence of terrestrial input and human activities was observed along with the flow direction, where the order of ∑NEOs concentration was PR_GZ (inland river, 64.5 ng/L) > Pearl River Estuary (estuary, 33.9 ng/L) > Xisha Islands of the South China Sea (SS_XS, open sea area, 27.0 ng/L); and the level in Northwestern South China Sea (coastal sea, 49.9 ng/L) was also higher than that in open sea area. The estimated annual fluxes of NEOs released into the South China Sea totaled 34.8 ± 20.4 tons, most of which come from the Pearl River basin. To the best of our knowledge, this is the first study to assess the concentrations, distribution, and source analysis of NEOs in river−estuary−ocean systems in South China.

“…The previous methods were mainly based on SPE and the sorbent generally had two sources, including commercial SPE cartridges and new SPE sorbent synthesized in the laboratory. Compared with the commercial SPE cartridges like C18 [18,19,24] and SDB-RPS [6], our self-made meltblown SPE cartridge could be reused and the core sorbent was taken from the medical mask, which was cheap and easy to obtain. Compared with the newly synthesized SPE sorbent, the preparation of meltblown SPE cartridge did not involve any chemical synthesis process, which fully met the needs of green analytical chemistry.…”

“…[2,3]. In the past years, fipronil had been put into use in a large amount due to its high insecticidal activity and low toxicity to mammals [4][5][6][7]. However, some studies had shown that fipronil exhibited high toxicity and adverse effects on non-target beneficial insects such as butterflies, bees, dragonflies, and many aquatic organisms [4,[6][7][8][9][10].…”

However, some studies had shown that fipronil exhibited high toxicity and adverse effects on non-target beneficial insects such as butterflies, bees, dragonflies, and many aquatic organisms [4,[6][7][8][9][10]. Meanwhile, there was evidence to suggest that short-term intake of a large amount of fipronil can induce adverse effects on the human nervous system, while long-term intake of fipronil could induce adverse effects on the liver, kidney, thyroid, and other organs and tissues [5,11].…”

In this study, a new method for the determination of fipronil and its three metabolites in environmental water samples was developed based on meltblown nonwoven fabric solid‐phase extraction combined with gas chromatography‐electron capture detection. As the core material of medical masks, meltblown nonwoven fabric is made of polypropylene superfine fibers which are randomly distributed and bonded together with a relatively large specific surface area and good permeability. Polypropylene as a high molecular hydrocarbon‐based polymer has the characteristics of good hydrophobicity and lipophilicity, which can be applied for the separation and enrichment of hydrophobic substances in food, environment, and biological samples. The meltblown nonwoven fabric is soft and can fill the solid‐phase extraction cartridge tightly. This aspect also makes it suitable to be used as an ideal solid‐phase extraction sorbent. A series of parameters influencing the extraction efficiency were investigated, and under the optimized conditions, fipronil and its three metabolites had a good linear relationship in the range of 0.2–100 μg/L with a correlation coefficient R2 of more than 0.999. The recoveries at three spiked concentrations were in the range of 99.2–107.3% with the relative standard deviations less than 9.8% (intra‐day) and 8.1% (inter‐day). The limit of detection for the four target analytes was in the range of 0.02–0.06 μg/L. Finally, this method was successfully applied in the analysis of fipronil and its three metabolites in various types of environmental water samples.

Neonicotinoids (NEOs) are a class of insecticides that have high insecticidal activity and are extensively used worldwide. However, increasing evidence suggests their long-term residual in the environment and toxic effects on nontarget organisms. NEO residues are frequently detected in water and consequently have created increasing levels of pollution and pose signi cant risks to humans. Many studies have conducted surveys of NEO concentrations in water; however, few studies have focused on global systematic reviews or meta-analyses of NEO concentrations in water. In the present study, 43 published papers from 10 countries were indexed for a meta-analysis of the global NEO distribution in water. Among these studies, most focus on eastern Asia and North America, which are involved in intensive agricultural activities. The order of mean concentrations is identi ed as imidacloprid (119.542 ± 15.656 ng L −1 ) > nitenpyram (88.076 ± 27.144 ng L −1 ) > thiamethoxam (59.752 ± 9.068 ng L −1 ) > dinotefuran (31.086 ± 9.275 ng L −1 ) > imidaclothiz (24.542 ± 2.906 ng L −1 ) > acetamiprid (23.360 ± 4.015 ng L −1 ) > thiacloprid (11.493 ± 5.095 ng L −1 ). Moreover, the relationship between NEO concentrations and some environmental factors is analyzed. NEO concentrations increase with temperature, oxidation-reduction potential and the percentage of cultivated crops but decrease with stream discharge, pH, dissolved oxygen and precipitation. NEO concentrations show no signi cant relations to turbidity and conductivity.The purpose of this review is to conduct a meta-analysis on the concentration of NEOs in global waters based on published detections from several countries to extend knowledge on the application of NEOs.
