“…However, inappropriate use of paraquat, for instance, repeated and excessive (beyond the recommended concentration) use, over the years may cause an accumulation of paraquat in the environment. Environmental contaminations of paraquat have been reported over the world, for example, Indonesia ( Ardiwinata et al, 2019 ), Brazil ( Veríssimo et al, 2018 ), and Thailand ( Teerakun et al, 2020 ). Although the concentrations of paraquat contamination in some areas are still below the tolerance limit, long-term exposure to those paraquat residues might result in harmful effects on humans and mammals and the food chain ( Huang et al, 2019 ).…”

Thailand is an agricultural country. However, agricultural productivity relies on the heavy use of herbicides, especially paraquat. Paraquat accumulation is emerging as a problem in an ever-growing portion of agricultural land. Paraquat residues are toxic to plants, animals, and aquatic organisms in the environment. Biological remediation is a process that can mitigate agricultural chemical contaminants. One of the interesting bioremediators is bacteria. Not only do certain soil bacteria remediate paraquat, but some of them also possess plant growth-promoting properties, which provide advantages in field application. Thus, this study aimed to screen soil bacteria that could degrade paraquat and, at the same time, promote plant growth. Bacteria were isolated from paraquat-treated agricultural soil in Mueang Kaen Pattana municipality, Chiang Mai province, Thailand. On the basis of morphological and 16S rDNA sequence analyses, the selected bacterium was identified as Bacillus aryabhattai strain MoB09. It is capable of growing in nitrogen-free media. B. aryabhattai growth and paraquat degradation were found to be optimum at pH 7 and 30°C. This selected strain also possessed plant growth-promoting abilities, including indole production, siderophore production, phosphate solubilization, and 1-aminocyclopropane-1-carboxylic acid deaminase activity. Paraquat degradation was also evaluated in pot experiments of cowpea (Vigna unguiculata). It was found that this strain could remediate the paraquat residue in both sterilized and non-sterilized soils. The cowpea plants grown in paraquat-contaminated soil with B. aryabhattai showed longer root and shoot lengths than those grown in soil without bacterial inoculation. In addition, B. aryabhattai also promoted the growth of cowpea under induced drought stress. These results suggested that B. aryabhattai could be applied to mitigate paraquat residue in soil and also to promote plant productivity for the organic crop production.

“…Based on the LOD of the P2‐aptasensor, it has a potential application for detecting paraquat contamination in the environment; for example, in drinking water because the permissible level is regulated in a range of 1−30 μg/L depending on each country's regulation, such as Australia (3.9 nM), Canada (38.8 nM) 17 . Also, the P2‐aptasensor can be used for detecting paraquat residues in agricultural soils as previously reported in a range of 7.1–14,436.6 ng/g (28.3 nM–57.8 μM) in several countries in Asia: India, Indonesia, and Thailand 5,6,41 . Although the developed paraquat aptasensor in this work has a narrow linear range of detection (5–50 mM), it covers the detection level of paraquat reported in many areas in Thailand.…”

Paraquat is a widely used herbicide for controlling weeds and grasses in agriculture, and its contaminated residues in agricultural areas are of increasing concern. This work reports the development of the sensitive and easy‐to‐use colorimetric aptasensor for screening paraquat residues in agricultural soil. The short DNA fragments derived from the original aptamer were analyzed for their capability to interact with paraquat by molecular dynamic simulation. The paraquat‐aptasensor was developed using the selected DNA fragment and gold nanoparticles. Its limit of detection (LOD) for paraquat is 2.76 nM, which is more sensitive than the aptasensor with long‐length aptamer (LOD = 12.98 nM). The developed aptasensor shows the selectivity to paraquat, but not to other tested herbicides; ametryn, atrazine, difenzoquat, 2,4‐D‐dimethyl ammonium, and glufosinate. The recovery rates of paraquat detection in the spiked soil samples were in a range of 99.5%–105.1%, with relative standard deviation values of <4%. The developed aptasensor was used to screen for paraquat residues in agricultural soils, and three out of 23 soil samples were tested positive for paraquat, which was confirmed by a high‐performance liquid chromatography analysis. These results suggested the potential application of the developed aptasensor to detect paraquat residues in agricultural sites.

“…Other commonly used EC pesticides such as glyphosate and paraquat had only one and four studies, − respectively, that quantified these pesticides (grades A and B combined). Likewise, other pesticides such as cypermethrin, methamidophos, and profenofos had few quantitative studies that were measured in a variety of environmental matrices (only three, one, and two studies in freshwater, respectively).…”

“…Another challenge in pesticide monitoring is in the detection of frequently used polar pesticides: paraquat and glyphosate and their metabolites. , These pesticides are used in rice, palm oil, food, and vegetable production in Southeast Asia. ,− Due to their polar properties, they cannot be detected in the same sample pretreated using the hydrophilic–lipophilic balanced (HLB) cartridge, which is regarded as the “gold-standard” cartridge for solid-phase extraction (SPE) sample cleanups for a wide range of EC compounds with high extraction efficiencies. ,, Due to the nature of the cartridge, polar pesticides such as paraquat and glyphosate will not be retained on the HLB cartridge but instead be lost together as waste with other interferences. Even then, glyphosate and its metabolites will require a different SPE cartridge and extraction procedure compared to paraquat and its metabolites in order to achieve high recoveries. ,, As such, the analyses of glyphosate and paraquat are often conducted as independent studies and not combined with other compounds, mainly due to the additional and tedious analytical procedures needed.…”

Occurrence of Emerging Contaminants in Southeast Asian Environments: Present Status, Challenges, and Future Prospects

2022

The status of emerging contaminant (EC) profiles in Southeast Asia is currently unclear and often overshadowed by studies conducted in developed regions such as North America, Europe, and Asia. EC research in Southeast Asia is especially critical due to its high population density and poor sanitation infrastructure that introduce large amounts of ECs into the aquatic environment. This literature Review investigated the status of EC research in 11 Southeast Asian countries. Key pharmaceutical groups such as antibiotics (sulfamethoxazole, trimethoprim, sulfamethazine, ciprofloxacin, and lincomycin) and nonsteroidal anti-inflammatory drugs (NSAIDs) (diclofenac, acetaminophen, and ibuprofen) were among the most frequently studied group of ECs, while other significant groups of interests in this Review included per-and polyfluoroalkyl substances (PFAS) and phthalate esters (PAEs). With most Southeast Asian countries having agrarian economies and the onset of climate change, the overutilization of antibiotics and pesticides to meet the commercial demand for agriculture and livestock products is a major threat to aquatic environments and even human health in this region. This Review identifies understudied emerging contaminant groups in Southeast Asia such as disinfectants and transformation byproducts and recommends future research directions for Southeast Asia, particularly focusing on seasonal trends of EC input into surface and groundwater environments.
