Abstract
Pesticide residues and mycotoxins are important maize contaminants, but their occurrence and dietary risks in fresh maize remain unclear. In this study, ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) methods were established for analyzing 70 pesticides and 15 mycotoxins and were applied to 302 fresh maize samples from three major regions in China. A total of 21 pesticides were detected at concentrations of 1.6-306 μg/kg and detection rates of 0.3-9.6%. Among the samples, 3.3% exceeded the Chinese maximum residue limits (MRLs). Three mycotoxins were detected at frequencies of 0.7-3.0% and concentrations of 2.6-19.1 μg/kg. Dietary risk assessment indicated that the estimated acute (%ARfD, 6.8 × 10-6-3.0 × 10-3) and chronic (%ADI, 7.0 × 10-5-1.2 × 10-1) risks from pesticide residues were well below 100%. The chronic dietary risk associated with the detected mycotoxins (%TDI) ranged from 3.9% to 30.1%, indicating no unacceptable risk.
This study investigated organochlorine pesticide (OCP) residues in agricultural soils and pepper samples to assess their ecological and human health risks. Eighty soil samples (pre‐[40] and post‐[40] pesticide application) and 40 pepper samples were analysed using gas chromatography–mass spectrometry. Bioaccumulati...

To characterize pesticide residues and age-specific dietary exposure risks in apples from Xinjiang’s main production areas, 120 samples were collected from Aksu, Ili, and Kashgar in October 2025 and screened for 82 pesticides using GC–MS/MS, LC–MS/MS, and GC–ECD. Chronic, acute, and cumulative dietary exposure was subs...

Eggplant holds a significant place in the human diet due to its nutritional value. Given its extensive cultivation across various regions of Iran and the widespread use of pesticides, monitoring these residues is essential for safeguarding public health. Accordingly, this study was conducted to identify and assess...

Aflatoxins are potent carcinogenic mycotoxins that frequently contaminate oilseed value chains in developing countries. This study assessed the occurrence of aflatoxins (AFB₁, AFTB₂, AFG₁, AFG₂) and associated dietary health risks in 69 samples comprising oilseeds, crude edible oils, and oil cakes collected from local...

ABSTRACT Pesticide contamination in dried fish presents a great food safety concern in Bangladesh. This study investigated the status of DDT and its metabolite levels in ninety‐six samples of two commercially available and widely consumed dried fish species, Harpadon nehereus and Trichiurus lepturus , collected across...

Organophosphate flame retardants (OPFRs) are widely used additive chemicals that can migrate into food during production, processing, and packaging, yet data on their occurrence and dietary risk in Taiwan remain limited. In this study, a validated high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS...
