Abstract The utilization of the thin film gradient diffusion technique has been on the rise for appraising the efficacy of soil cadmium (Cd). Nonetheless, in contrast to conventional methodologies employed to gauge the efficacy of soil Cd, there exists a dearth of adequate research concerning whether the technique of diffusive gradients in thin films (DGT) can furnish a more precise and all‐encompassing evaluation of soil Cd effectiveness in soil passivation and remediation procedures.

Human infections by environmental bacteria is becoming an increasing problem and has become a matter of great concern due to the adverse effects worldwide. In this study, we reported a new environmental pathogen. Isolate GX5518T was a novel Gram-negative, aerobic, non-motile, pleomorphic and red-pigmented bacterium, was isolated from human wound secretions (GuangXi, People’s Republic of China).

Veterinary drugs (VDs) are regulated to prevent their abuse or misuse and protect humans that consume animal-based food products from exposure to VD residues. VD residues are managed according to the maximum residue limits (MRLs) or by prohibiting the use of VDs based on their residual properties and toxicities. However, all VD residues, even those that are not managed by MRLs, in animal-based food products will be regulated for public health improvement.

Tomato, Lycopersicon esculentum L. is grown widely as an important day-to-day demand vegetable. The crop is attacked by various polyphagous insect pests like tomato fruit borer, stink bug, cabbage looper, flea beetle, aphids, whitefly, two-spotted spider mite, etc., and oligophagous insects like leaf-miner, five-spotted hawkmoth, etc. To combat the damage and yield loss, various chemical insecticides were sprayed on tomatoes under field conditions.

Herein, a novel electrochemical sensing platform is designed for the simultaneous detection of Cd2+ and Pb2+, using MXene@rGO composite aerogel-doped UiO-66-NH2. The MXene@rGO composite aerogel not only serves as the support structure for UiO-66-NH2, but also improves the conductivity of the composite by accelerating the electron transport in the matrix.

Abstract Lufenuron is a benzoylurea insecticide currently in use to combat sea lice infestation in salmon aquaculture in Chile. With pending approval in Norway, the aim of this work was to study the uptake and toxicity of lufenuron in liver tissue of Atlantic salmon. Juvenile salmon weighing 40 g were given a standard 7‐day oral dose, and bioaccumulation and transcriptional responses in the liver were examined 1 day after the end‐of‐treatment (day 8) and after 1 week of elimination (day 14).

Abiotic factors and rhizosphere microbial populations influence arsenic accumulation in rice grains. Although mineral and organic surfaces are keystones in element cycling, localization of specific microbial reactions in the root/soil/pore water system is still unclear.

Occurrence of antibiotics in animal sourced foods not only affects economy but also poses potential health risks. The present study aimed to validate simultaneous detection of amoxicillin, penicillin – G and enrofloxacin in raw migratory goat milk (N=223) by HPLC-DAD and assess human health risks in Western Himalayan region, India.

This study aimed to detect 11 carbamate pesticide residues in raw and pasteurized camel milk samples collected from the UAE using UHPLC-MSMS. A method was developed and validated by evaluating LOD, LOQ, linearity, extraction recovery, repeatability, intermediate precision, and matrix effect. Due to the high protein and fat content in camel milk, a sample preparation step was necessary to avoid potential interference during analysis.

Background Fruit juices are one of the most non-alcoholic beverages consumed in the world. Essential elements and other nutrients present in fruit juices play an important role in human well-being. However, fruit juices may also contain potentially toxic elements at trace levels, causing health risks.

Background Supercritical fluid extraction (SFE) is a fast, versatile, and solvent-efficient automatic extraction method. Despite its advantages, the results of our proficiency tests imply that the applicability assessments of SFE for pesticide residues were insufficient.

Background Clenbuterol (CLB) is approved as a veterinary drug because of its tracheal smooth muscle and uterine relaxant effects. However, if improperly administered for the purpose of fattening livestock, CLB can remain in the organs, which may pose a health hazard to humans.

Heavy metal (HM) contamination of grain crops is a potential health risk and removal of grain outer layers can reduce contamination to safe levels. This study investigated the reduction of lead (Pb), arsenic (As), and cadmium (Cd) using an abrasive decortication process in samples of quinoa and rice cultivated in southern Perú, where HM contamination has been reported.

Previous research has demonstrated that lead (Pb2+, for the remainder of the paper referred to as Pb) and other heavy metals are present in table eggs from backyard birds. While the source of Pb exposure is unknown, exposure to the environment via the foraging behavior of backyard poultry is likely a significant factor.

Abstract Bonvital® is the trade name for a feed additive currently authorised for use in piglets, pigs for fattening, sows, chickens for fattening, laying hens, chickens reared for laying and minor poultry species (other than those used for laying). This opinion concerns the renewal of the authorisation of Bonvital® as a zootechnical additive for chickens reared for laying and minor poultry species other than those used for laying.

Incidence and mortality rates of gastrointestinal (GI) and oral cancers are among the highest in the world, compared to other cancers. GI cancers include esophageal, gastric, colon, rectal, liver, and pancreatic cancers, with colorectal cancer being the most common. Oral cancer, which is included in the head and neck cancers category, is one of the most important causes of death in India.

Lead ions are a toxic metal that can enter the human body through the diet and negatively impact human health. A wide variety of foods, such as vegetables, meat, aquatic product, and drinking water, can be contaminated with lead ions. In this study, a highly sensitive immunochromatographic assay (ICA) based on antibody-oriented probe and silver enhancement was established for the qualitative and quantitative determination of lead ions in drinking water.

From farm to plate, food meets various challenges and pollution. Food detection is essential to ensure food safety. Although detection techniques have obtained great development, the accuracy, sensitivity and operating conditions still have room for improvement. Composed of dielectric media with different refractive indices to form a periodic structure, an optical material named photonic crystal (PC) can offer a breakthrough.

Pymetrozine, a member of the azomethine pyridine group, is gaining popularity among paddy farmers due to its anti-feeding properties against homopteran insects like planthoppers, whiteflies, and aphids on a wide range of fields, fruits, and ornamental crops.

Microplastics (MPs) increase the effective state of heavy metals (HMs) in soil and seriously threaten the yield and quality of peanuts (Arachis Hypogea L.). Kaolinite (KL) has the potential to ameliorate MP- and HM- contaminated soils, but the mechanism of action between them is not well understood.

Exposure to arsenic, an environmental contaminant, is known to cause arsenicosis and cancer. Although considerable research has been conducted to understand the underlying mechanism responsible for arsenic-induced cancers, the precise molecular mechanisms remain unknown, especially at the epigenetic regulation level. Long non-coding RNAs (LncRNAs) that have been shown to mediate various biological processes, including proliferation, apoptosis, necrosis, and mutagenesis.

Abstract Cheap and widely available calcium‐based materials have gained popularity for remediating cadmium‐contaminated soils, but their potential to address cadmium (Cd) toxicity in acidic soils remains deeply understudied. The current study investigated the effects of calcined oyster shells (COS) and dolomite (DM), applied at a rate of 30 g kg‐1, on Cd availability and its accumulation in spinach plants in acidic Cd‐contaminated soils (Cd concentration: 4.42 mg kg‐1).
