“…Thiabendazole (TBZ) residues in agricultural products and food can affect the quality of products and people’s dietary safety, so they are considered as emerging contaminants . The U.S. Environmental Protection Agency (EPA) has classified TBZ as a carcinogen .…”

“…Thiabendazole (TBZ) residues in agricultural products and food can affect the quality of products and people's dietary safety, so they are considered as emerging contaminants. 53 The U.S. Environmental Protection Agency (EPA) has classified TBZ as a carcinogen. 54 According to EU legislation, maximum residue limits (MRLs) for raw fruits and vegetables have been established in the range of 0.05−15 ppm.…”

Rapid and Robust Analysis of Coumatetralyl in Environmental Water and Human Urine Using a Portable Raman Spectrometer

“…Serial dilution of the stock solutions was then prepared with water or urine. A pooled human urine sample from 15 volunteers was used to exclude individual differences, given possible confounding factors in the experiment. ,− This study was approved by the ethics committee of the Shandong Academy of Occupational Health and Occupational Medicine (SDZFY-EC-H-2021-08) and conformed to the principles set out in the WMA Declaration of Helsinki.…”

“…Although these methods are precise, they usually require complex and time-consuming preprocessing steps as well as skilled expertise, which greatly limit their field applications. , Currently, a rapid and user-friendly detection strategy for on-site detection and point-of-care monitoring of CMTT is desperately needed. Surface-enhanced Raman scattering (SERS) has multiple advantages over traditional analysis platforms, such as ultra-sensitive fingerprint acquisition, simple operation, fast readout speed, and low water interference. − These merits make SERS technology a promising analysis alternative and has been increasingly used in environmental analysis, bio-medicine, , and food safety . Recently, SERS has shown satisfactory performance in pesticide detection in soil and vegetable samples .…”

Molybdenum Disulfide (MoS2): An Emerging Multifunctional Nanomaterial for Sensing and Removal of Agricultural Contaminants

“…29 With the assistance of the advanced electro-optical techniques of fluorometric approaches, electrochemical methods, and SERS, MoS 2 -based sensors provide a broad arsenal for agricultural contaminant qualitative analysis and indepth quantitative determination. 30 In this context, to blaze the trail for broad interpretation of MoS 2 , a large number of 31 The emergence of MoS 2 provides an opportunity to improve the capability of colorimetric sensors. The unique advantages of MoS 2 for colorimetric sensing include the following: (1) MoS 2 often possesses graphene-analogous structure with large specific surface area, providing abundant catalytic sites; (2) the exposed active sites in MoS 2 allow it to be functionalized by other substrates; (3) superior stabilization of the MoS 2 can guarantee it for intermediate and subsequent reactions.…”
