Background: Carbosulfan (CBS) is a widely used carbamate pesticide in agricultural production, its easy decomposition into hypertoxic carbofuran poses serious threats to human health and food safety. Therefore, sensitive and accurate detection of CBS is of significant importance. Conventional chromatography-based techniques require expensive instruments and complicated sample pretreatment, limiting their application for fast detection.

The emission of contaminants of emerging concern (CECs) from wastewater treatment plants has been extensively studied; however, less attention has been paid to municipal solid waste treatment plants (MSWTPs), which can also be a potential source for CECs into surface water (SW) and groundwater (GW) ecosystems. In this work, the environmental impact of a MSWTP located in the province of Castelló, Spain, was studied along a period of ten years (from 2012 to 2022). A total of 173 water samples (including SW and GW) collected from the surrounding of this plant were monitored for 93 compounds (pharmaceuticals and pesticides) by using liquid chromatography coupled to tandem mass spectrometry with triple quadrupole.

Article Synopsis
- The use of synthetic pesticides can lead to pests developing resistance, making these pesticides less effective over time, largely due to efflux pumps like the ABCC transporters.
- In this study, researchers identified the potential pesticide substrates of a specific transporter, TcABCC-9C, from the red flour beetle and found that the insecticides carbofuran and buprofezin bind to it.
- The results highlight TcABCC-9C's important role in developing multi-pesticide resistance, suggesting it could be a target for future pest management strategies, and the methodology could help in understanding other transporter-related insecticide resistances.
Discovery of multiple bee-hazardous pesticides in ornamental plants via the Bee-Plex multi-target microsphere screening method.

Exposure to pesticides is one of the main drivers of global bee decline. However, the occurrence of pesticides in bee-attracting crops remains underexposed due to the lack of efficient on-site screening approaches for multi-analyte monitoring. Utilizing color-encoded superparamagnetic microspheres, we constructed a portable 8-plex indirect competitive microsphere-based immunoassay for the simultaneous determination of multiple bee-hazardous residues (Bee-Plex).

Many countries widely use pesticides to increase crop productivity in agriculture. However, their excessive and indiscriminate use contaminates soil and other environments and affects edaphic microbial communities. We aimed to examine how the pesticides carbofuran and picloram affect the structure and functionality of soil microbiota using cultivation-independent methods.
