“…To protect crops from pathogens, fungi, weeds and insects, millions of tons of pesticides are applied each year in order to maintain agricultural productivity [ 1 , 2 , 3 , 4 ]. Herbicides and insecticides are the most common pesticides used, accounting for about 47.5% and 29.5% of the total pesticide consumption [ 1 , 5 ].…”

“…So far, hundreds of pesticides are registered in the European Union (EU) and most of them have maximum residue limits (MRLs) in foods of plant origin to protect consumers against toxic chemicals [ 6 ]. While many of these chemicals are readily degraded in the environment or have no adverse effects on human health, there are some for which there is little toxicological information [ 2 , 3 , 4 , 5 , 7 , 8 , 9 ]. The extensive use of pesticides, however, also means that they appear and accumulate in soil, clay or in water samples based on the hydrophobicity of the molecules [ 2 , 3 , 4 , 10 ].…”

“…A recent Hungarian study on pesticides in ground- and surface water reported that more than half samples contained detectable levels of pesticides, and about 5% of the samples contained pesticides at levels exceeding the 100 ng/L maximum concentration level for individual pesticides, and 500 ng/L maximum concentration level for the sum of pesticides as specified by EU directives [ 11 , 12 , 13 ]. Additionally, numerous research articles have reported the frequent detection of pesticides in water worldwide [ 2 , 3 , 4 , 5 , 7 , 8 , 9 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. The other environmental concern is the fate of pesticides, which can lead to harmful metabolites with unknown toxicity to animals and humans [ 3 , 8 , 9 ].…”

“…According to Bexfield et al [ 25 ], among the 41% of groundwater containing pesticide compounds, three-quarters contained metabolites as well. Therefore, there is a great need to monitor pesticide residues in water samples using state-of-the-art analytical techniques that enable the simultaneous analysis of high numbers of compounds [ 2 ].…”

The presence of pesticide residues in water is a huge worldwide concern. In this paper we described the development and validation of a new liquid chromatography tandem mass spectrometric (LC-MS/MS) method for both screening and quantification of pesticides in water samples. In the sample preparation stage, the samples were buffered to pH 7.0 and pre-concentrated on polymeric-based cartridges via solid-phase extraction (SPE). Highly sensitive detection was carried out with mobile phases containing only 5 mM ammonium formate (pH of 6.8) as an eluent additive and using only positive ionization mode in MS/MS instrument. Hence, only 200-fold sample enrichment was required to set a screening detection limit (SDL) and reporting limit (RL) of 10 ng/L. The confirmatory method was validated at 10 and 100 ng/L spiking levels. The apparent recoveries obtained from the matrix-matched calibration (5–500 ng/L) were within the acceptable range (60–120%), also the precision (relative standard deviation, RSD) was not higher than 20%. During the development, 480 pesticides were tested and 330 compounds fulfilled the requirements of validation. The method was successfully applied to proficiency test samples to evaluate its accuracy. Moreover, the method robustness test was carried out using higher sample volume (500 mL) followed by automated SPE enrichment. Finally, the method was used to analyze 20 real samples, in which some compounds were detected around 10 ng/L, but never exceeded the assay maximum level.

Atrazine is the pesticide that is found in surface water sources more frequently than any other pesticide. Therefore, the paper describes ultrasensitive detection of atrazine from fruit and water samples, using an on‐site screening platforms incorporating stochastic microsensors based on graphite powder modified with 4‐tert‐butylcalix [4] arene and with calix [4] arene‐25,26,27,28‐tetrol. Limits of determination of 0.1 fmol L ‐1 were recorded while the sensors could have been used on wide concentration ranges, between 0.1 fmol L ‐1 and 0.1mmol L ‐1. Recoveries higher than 95.00% were recorded when used for the assay of atrazine in water, fruits and vegetables.

Aliphatic‐aromatic biodegradable polyesters, characterized by their exceptional macroscopic properties and significant cost‐effectiveness advantages, have facilitated the development of numerous commercial products. In this study, a series of biodegradable poly(butylene alkylene carboxylate‐co‐terephthalate) (PBXT) copolymers with varying methylene numbers in the alkylene units (0, 2, 4, and 8) were synthesized. These copolymers, namely poly(butylene oxalate‐co‐terephthalate) (PBOT), poly(butylene succinate‐co‐terephthalate) (PBST), poly(butylene adipate‐co‐terephthalate) (PBAT), and poly(butylene sebacate‐co‐terephthalate) (PBSeT), were prepared with nearly identical structural and molar compositions. The objective of this study was to comprehensively examine the impact of alkylene unit length on the barrier properties of the materials, delving into aspects such as crystallinity, free volume, molecular chain mobility, as well as adsorption and diffusion of gases within the materials. The findings indicated a decrease in crystallinity from 17.2% for PBOT to 10.2% for PBSeT as the alkylene chain length increased, while maintaining the same chemical composition. Concurrently, the fractional free volume increased from 0.9% to 2.6%, and the melt flow activation energy decreased from 106.6 kJ/mol to 52.1 kJ/mol. Importantly, theoretical calculations were performed, demonstrating that the predominant site for gas adsorption and diffusion was within the material's free volume. These combined observations indicated a gradual decrease in barrier properties as the number of methylene groups in the length of the alkylene unit increases.This article is protected by copyright.
