“…Due to its high toxicity and adverse effects on the environment, according to Circular 10/2020/TT-BNNPTNT, effective from October 25, 2020: pesticides containing CPF will not be produced or imported, only sold used until February 12, 2021. In the world, there are many studies on residual as well as risk assessment of CPF in soil, water and in agricultural products. Typical pesticide residue studies include Determination of Chlorpyrifos Residues in Lettuce [7], pesticide contamination in soil of intensive horticulture [8] and pesticide residues in orchard soil [9]. In addition, studies on the ecological risk of pesticides have been conducted in Ethiopia [10], USA [11], Nepal [12][13] and Iran [14] which have provided important information for future.…”

This study was conducted to investigate the residual of Chlorpyrifos (CPF) in coffee growing soil at Lam Ha district, Lam Dong province. Fifteen soil samples were collected from coffee intensive gardens in the Phi To, Nam Ha, Me Linh and Dong Thanh communes of Lam Ha district during the February 2023. The physico-chemical properties of the samples were analyzed such as pH, organic carbon, moisture content and mechanical composition of the soil while CPF was analyzed by gas chromatography-mass spectrometry. Soil samples with pH ranged from 3.48-4.45, moisture content 28.2-33.8% and OC 2.3-3.4%. Chlorpyrifos concentration of soil samples ranged from not detected to 954 µg/kg. The ecological risk of chlorpyrifos residual in soil was evaluated by using the risk quotient (RQ). The results of this study will be used to propose solutions to reduce pollution.

“…For the sensing of CPS, the number of traditional analytical techniques have been used for a long time involving gas chromatography-mass spectrometry (GC-MS), 8 biosensors, 9 high performance liquid chromatography (HPLC), 10 chemiluminescence (CL) 11 and surface-enhanced Raman scattering (SERS). 12 Although these methods have their significant importance for the detection of CPS, however the use is limited being extremely expensive, time-consuming with laborious sample preparation requirements.…”

A novel synthetically accessible electrochemical sensor has been developed for the detection of chlorpyrifos (CPS) at a very minimal level by utilizing a glassy carbon electrode (GCE) modified with RGO functionalized fluorenone derivative (RGO-NS). The structural and morphological aspects of the derived composite were assessed by Fourier transform infrared spectroscopy, X-ray diffraction, field-emission scanning electron microscopy, and density functional theory with in-depth electrochemical analysis. The fluorenone appended with distinct functionalities has supported the reversible redox reactions of CPS, thus, boosting the specificity of the sensor. The design of the electrochemical sensors involved functionalization of RGO possessing high adsorption capacity, which has further amplified the electrochemical sensitivity. The sensing response has been credited to the reduction associated with hydrogen ion which on addition of CPS gets quenched due to catalytic reaction between the two. The synergy has resulted in the low detection limit of 8.89 ng ml-1 for CPS along with reliable detection of CPS in soil samples without spiking. The framework has the excellent future prospects in the practical management of pernicious pesticides usually employed in agricultural fields and their residues on food products posing a serious danger to human health.

Pesticides play a critical role in terms of agricultural output nowadays. On top of that, pesticides provide economic support to our farmers. However, the usage of pesticides has created a public health issue and environmental hazard. Chlorpyrifos, an organophosphate pesticide, is extensively applied as an insecticide, acaricide, and termiticide against pests in a variety of applications. Environmental pollution has occurred because of the widespread usage of chlorpyrifos, and it is harming several ecosystems including soil, sediment, water, air, and biogeochemical cycles. While residual levels in soil, water, vegetables, foodstuffs, and human uids have been discovered, chlorpyrifos has also been found in the sediment, soil, and water.The irrefutable pieces of evidence indicate that chlorpyrifos exposure inhibits the choline esterase enzyme, which impairs the ability of the body to use choline and as a result, neurological, immunological, and psychological consequences are seen in people and the natural environment. Several research studies have been conducted worldwide to identify and develop chlorpyrifos remediation approaches and its derivatives from the environment. Currently, many detoxi cation methods are available for pesticides such as chlorpyrifos, but recent research has shown that the breakdown of chlorpyrifos using bacteria is the most pro cient, cost-effective, and sustainable. This current article aims to outline relevant research events and provide a summary of the possible breakdown of chlorpyrifos into a variety of compounds, along with a discussion of analytical summaries of current research ndings on bacterial degradation of chlorpyrifos and the potential degradation mechanism. year, 2 million tonnes of pesticides are used worldwide to prevent loss to crops. Yet, only around 0.1% of these compounds operate on targeted species, and 90-99% of them stay in the atmosphere due to their refractory and persistent character. Ultimately, they seep into the soil and water bodies, contaminating the clean environment (Raj and Kumar, 2022;Skendžić et al., 2021).CPY also showed detrimental in uences on biota and the ecosystem. Studies have linked chlorpyrifos exposure to declines in bird populations, as well as reproductive and developmental problems in sh, frogs, and other aquatic species. Chlorpyrifos can persist in the ecosystem for weeks or months and can be transported extended distances by air and water (Nandi et al., 2022). Despite these concerns, chlorpyrifos has remained in use in many countries, including the United States, where it has been the subject of ongoing controversy and debate. In 2015, the US Environmental Protection Agency proposed to invalidate all food tolerances for chlorpyrifos, e ciently prohibiting its use in agriculture. However, this proposal was overturned in 2017 by the new administration, citing a lack of scienti c evidence (Hicks, 2020;Trasande, 2017).The controversy surrounding chlorpyrifos has highlighted the challenges of regulating and managing hazardous chemicals in mod...
