“…However, CUPs are not transient or harmless in the environment. These pesticides are being increasingly studied because they have been found to have distinct half-lives in natural conditions from previously expected through laboratory experiments (Gouin, Cousins, et al, 2004;Ruggirello et al, 2010;Thinh et al, 2018) and have been detected in remote areas such as mountains, lakes, groundwater, and polar regions beyond the direct influence of human activities (Guida et al, 2018;Kurt-Karakus et al, 2010;Luek et al, 2017;Muir et al, 2004;Westgate et al, 2013;Yao et al, 2007). Furthermore, the bioaccumulation of CUPs and their passage through food chains pose potential risks to human health (Dittmann et al, 2012;Macdonald et al, 2002).…”

“…For example, oceanic currents transport 80-90% of β-hexachlorocyclohexane to the Arctic Ocean, with atmospheric transport being almost negligible (Li et al, 2002). The long-range atmospheric transport (LRAT) model describes a "grasshopper effect" (Wania & Mackay, 1993), which enables the rapid transport of pollutants to remote regions (Bailey et al, 2000;Bigot et al, 2016;Guida et al, 2018;Hung et al, 2016). The model is appropriate for volatile or semivolatile organic compounds with high Henry's law constants.…”

Spatial Distributions and Seasonal Changes of Current‐Use Pesticides from the North Pacific to the Arctic Oceans

et al. 2019

Distributions of eight targeted current‐use pesticides (CUPs) chloroneb, simazine, atrazine, alachlor, dacthal, chlorobenzilate, methoxychlor, and permethrin were investigated in seawater and the atmosphere in a region covering the North Pacific to the Arctic Oceans during the 7th and 8th Chinese National Arctic Research Expedition (2016 and 2017) voyages of the research vessel R/V Xuelong (Snow Dragon in English). Total CUP concentrations in seawater have prominent seasonal and latitudinal trends, with higher concentrations occurring at lower latitudes in early summer. The major contributors of the CUPs (∑8CUP) did not alter over different seasons with dominant chloroneb, alachlor, and atrazine accounting for more than 90%, but their concentrations did have marked seasonal changes. However, the compositions of the eight analyzed CUPs varied indistinctly between seasons indicating a possible combined environmental impact on these compounds rather than the effects of individual chemical properties. Three‐day backward air mass trajectories indicate that atmospheric masses from northeastern China are responsible for the high concentrations of CUPs in East China and Japan Seas, whereas those from the North Atlantic Ocean contribute to the low levels in local area. Fugacity ratios indicate potential volatilization and equilibrium of chloroneb in the Canada Basin of the Arctic Ocean and Japan Sea, respectively, and deposition of other CUPs in both regions. However, atmospheric concentrations are decoupled from those in seawater, which indicates a low exchange rate.

“…Table 3 reviews the concentrations of pyrethroid insecticides bounds to aerosols or as vapors. The first report of pyrethroids in the gas phase of Brazilian alpine reserves showed that cypermethrin was the second pesticide in abundance, whereas gas phase concentrations of legacy pollutants, such as chlordane, chlorinated cyclodienes and hexachlorobenzene, were around background levels [70]. In aerosols and in the gas phase of Guangzhou (south China), eight pyrethroids were detected, and cypermethrin was the dominant one [71].…”

As a consequence of their increasing use, pyrethroid insecticides are recognized as a threat for nontarget species and ecosystem health. The present chapter gives a state-of-art overview of individual pyrethroid occurrence in waters and sediments worldwide, together with recent reports of their quantification in the atmospheric gas and aerosol phases. Degradation rates, transport processes, and partitioning of pyrethroids between environmental phases are reviewed. River flow efficiently transports pyrethroids to river mouths and estuaries, while pyrethroid

“…Various pesticides are widely used around the world due to their high efficiency and reliability for crop protection against pests and increasing agricultural production (He, Xu, Zhang, Liu, & Liu, 2019; Yang, Qian et al, 2019). However, improper use of pesticides will not only cause pollution to the ecosystem (Guida, Meire, Torres, & Malm, 2018) but also have a negative impact on humans (Amvrazi & Albanis, 2006). Ingestion of agricultural products with excessive pesticide residues may increase the risk of multiple cancers, which include leukemia, prostate, and colorectal cancer (Lozowicka, 2015; Sabarwal, Kumara, & Singha, 2018).…”

Different organophosphorus pesticides (OPs) normally vary in the level of toxicity to human health, but common electrochemical identification methods usually require complex electrode fabrication processes and high detection cost. To overcome these problems, a pesticide residues identification method based on multilayer paper-based microfluidic chip was proposed. The microfluidic chip integrates the enzyme inhibition and a label-free screen-printed carbon electrode (SPCE). Three different pesticides were selected as study objects, respectively, avermectin, phoxim, dimethoate. This chip realizes on-chip identification via analyzing impedance time-sequence spectrum data aroused by the enzyme inhibition during the 15 min period. A classification model based on principal component analysis (PCA) and support vector machines (SVMs) was established to evaluate these data. Furthermore, the real-world sample (lettuce) was tested to verify the feasibility of the proposed detection method. The results showed that the classification accuracy was achieved around 93% in multiple experiments. Therefore, the method has good stability and specificity in rapid identification of different pesticides. Practical Applications Identification of pesticide types is essential to human health, for this, impedance time-sequence spectrum data aroused by the enzyme inhibition during the 15 min period was used to establish a classification model to identity different types of pesticides. In this article, multilayer paper-based microfluidic chip and a label-free screenprinted carbon electrode (SPCE) was proposed without complicated operation steps and expensive cost, which provide a basis for establishment of the rapid pesticide discriminator.
