Residue levels of seven pesticides were analyzed in thirty-five samples Extra Virgin Olive Oil to assess the health risk consuming Italian oils correlated with presence these pesticides. An in-house analytical procedure was developed and validated, consisting a specific dispersive solid-phase extraction using QuEChERS technique qualitative-quantitative analysis liquid chromatography coupled tandem mass spectrometry. Thirty-four percent contaminated pesticide residues; concentration range...
Bisphenol A (BPA) and bisphenol B (BPB) concentrations were determined in peeled canned tomatoes of different brands bought Italian supermarkets. Tomato samples analyzed packaged cans coated with either epoxyphenolic lacquer or low BADGE enamel. solid phase extraction (SPE) was performed on C-18 Strata E cartridge followed by a step Florisil cartridge. Detection quantitation reversed high-performance liquid chromatography (RP-HPLC) method both UV fluorescence detection (FD). On the total 42...
Green coffee beans and their derivatives are employed in dietary supplements, pharmaceuticals, cosmetic formulations owing to antioxidant properties secondary metabolites, which may play a role preventing metabolic syndrome. Mycotoxins, particularly ochratoxin A (OTA), present considerable contamination risk regulated under strict guidelines established by the European Union various food safety authorities. This study validates reverse-phase HPLC method with fluorimetric detector for...
While providing considerable societal and economic benefits, plastic packaging leads to global pollution poses health risks. Plastic additives like alkylphenols (APs) can interfere with endocrine functions even at low concentrations. Therefore, developing validating analytical methods for their routine dosage in foods is paramount. The present work validated a chromatographic method quantify (4-tert-octylphenol, 4-n-octylphenol mono-ethoxylate, 4-n-octylphenol, 4-n-nonylphenol) milk. uses...
Background: Growing evidence suggests that the endocannabinoid system is involved in pathogenesis of Alzheimer's disease (AD) and atherosclerosis. Objective: The purpose this study was to investigate activation syste
Microplastics, MPs, plastic fragments with a dimension lower than 5 mm, and microfibers, MFs, synthetic natural/artificial fibrous diameter 50 μm, are ubiquitous pollutants identified in different environmental compartments. In this work the occurrence of MPs MFs on honeybees, Apis mellifera, beehive products was evaluated, using Fourier transform infrared microspectroscopy, confirming that widely present as air contaminants all apiary's areas (high low urbanized areas) Southern Italy....
Green coffee is essential in many tropical economies. Its cultivation often necessitates using pesticides that can leave behind residues harmful to human health. To ensure consumer safety, the European Community has set strict maximum residue limits (ranging from 0.01 1.0 mg/kg) for green sold within Europe. However, lack of official testing methods neonicotinoids (NEOs) a problem, as laboratories must spend resources and time developing validating suitable analytical methods. This study...
The consumption of plant-based beverages as an alternative to cow's milk has recently gained vast attention worldwide. aim this work is monitor the intake Bisphenol A (BPA), B (BPB) and S (BPS) in Italian population through these foodstuffs. Specifically, development validation analytical procedure for quantitative determination analytes by liquid chromatography coupled tandem mass spectrometry was reported. Thirty-four samples (soya, coconut, almond, oats rice) popular brands marketed Italy...
The monitoring of the contamination levels bisphenol A (BPA) and its congeners B (BPB) F (BPF) in foodstuffs is a necessary process for assessment consumers' risk. After development validation method using Strata® C18-E cartridge cleanup with detection by liquid chromatography coupled to tandem mass spectrometry, forty-six samples fruit juices, sold on Italian markets, have been analysed assess concentration BPA, BPB BPF. BPF were not detected any samples, BPA was found 33 % samples....
Neonicotinoids (NEOs), used as insecticides against aphids, whiteflies, lepidopterans, and beetles, have numerous detrimental impacts on human health, including chronic illnesses, cancer, infertility, birth anomalies. Monitoring the residues in food products is necessary to guarantee public health ecological balance. The present work validated a new method measure seven neonicotinoid (acetamiprid ACT, clothianidin CLT, dinotefuran DNT, imidacloprid IMD, nitenpyram NTP, thiacloprid TCP,...
Understanding and quantifying the adsorption desorption of herbicides by soil is important for predicting their fate transport in environment. Here we report a study concerning desorption, four different soils, imazosulfuron, 1-(2-chloroimidazo[1,2-a]pyridin-3-ylsulfonyl)-3-(4, 6-dimethoxypyrimidin-2-yl)urea, new sulfonylurea herbicide. Both phenomena are well-described Freundlich equation, which shows this herbicide to be little adsorbed each soils investigated. The constants, K(f-ads),...
Knowledge of the kinetics and pathways hydrolytic degradation is crucial to prediction fate transport mechanism chemicals. This work first describes chemical hydrolysis imazosulfuron, a new sulfonylurea herbicide, evaluates results propose pathway. The imazosulfuron has been studied in aqueous buffers both within pH range 1.9−12.3 at ambient temperature (thermostated 25 ± 2 °C) 3.6 15−55 °C. rate was characterized by first-order kinetics, pH- temperature-dependent, accelerated acidic...

The degradation of imazosulfuron sandy loam soil (10-15 cm depth) has been investigated under aerobic anaerobic...
We describe a method for determination of cymoxanil, 1-2-cyano-2-methoxy(iminoacetyl)-3-ethylurea, in drinking water and soil, using reversed-phase HPLC with UV detection at 240 nm mobile phase acetonitrile-water (30:70, v/v). Fortified samples (1.0 L) were extracted solid-phase extraction on Strata X. Soil (20 g) acetone the extracts transferred onto C18E.

Abstract Photolysis of imazosulfuron was studied in aqueous solution under UV light. The reaction followed a pseudo‐first‐order kinetic with significant correlation coefficient. major photodegradation products after irradiation light were separated and tentatively identified by HPLC‐MS analysis as (4,6‐dimethoxypyrimidine‐2‐yl)aminocarbonylsulfamic acid, 4,6‐dimethoxy‐2‐ureidopyrimidine 2,2′‐dichloro‐[3,3′] bi [imidazo[1,2‐a] pyridinyl]. results indicate that different pathways are followed: (1)...
