The combined of ultrasound and ozone notably expedites the degradation process. In addition, the combined treatment preserves the pak choi's vitamin C content and color to a greater extent than treatments involving ultrasound or ozone alone, while still accomplishing the same level of pesticide removal. Abstract The effect of ultrasound, ozone, and their combination treatment on the removal of two common pesticides (trichlorfon and phoxim) in pak choi samples was studied in this work.

Lincomycin (LCM) is an antibiotic used to treat severe bacterial infections in livestock and companion animals. In this study, we aimed to investigate the oral bioavailability of LCM with PK data after IV and PO administration and to compare differences in drug residue patterns in eggs. To ensure food safety, an additional study on egg residue was conducted using three different commercial LCM drugs.

Abstract The marine finfish and crustaceans contribute immensely to human nutrition. Harvesting marine food‐fish to meet the global demand has become a challenge due to reduction of the fishery areas and food safety hazards associated with increased pre‐harvest and post‐harvest contaminations. The causes of low fish availability and contaminations were reviewed following the published literature from 2000 to 2023.

Rice is the major source of arsenic (As) intake in humans, as this staple crop readily accumulates As in the grain. Identifying the genes and molecular mechanisms underlying As accumulation and tolerance is a crucial step toward developing rice with reduced As levels. We identified 25 rice genes that improve As tolerance in yeast cells by expressing a complementary DNA (cDNA) library generated from As-treated rice roots.

Se (Selenium) has been reported to be an important protective agent to decreases Cd (Cadmium) induced toxic in plants. However, it remains unclear how Se mitigates the uptake of Cd and increased the resistance to Cd toxicity. Hydroponic experiments were arranged to investigate the changes of physiological properties, root cell membrane integrity and Cd-related transporter genes in rape seedlings.

The gut barrier plays an essential role in maintaining homeostasis and is usually composed of a mechanical barrier, a chemical barrier, an immune barrier, and a biological barrier. However, the impacts of lead (Pb) exposure on avian gut barrier are still unclear.

The presence of pesticide residues in vegetables is a worldwide issue regarding food safety. This study explores the efficacy of a novel advanced oxidation process (AOP), namely the coupled ultrasonic-ozonation (US/O3) process, for removing six commonly found pesticides from vegetables.

The potato chloroplast was transformed with codon optimized synthetic hybrid cry gene (SN19) to mitigate crop losses by Colorado potato beetle (CPB). The bombarded explants (leaves and internode) were cultured on MS medium supplemented with BAP (2.0 mg/l), NAA (0.2 mg/l), TDZ (2.0 mg/l) and GA3 (0.1 mg/l); spectinomycin 50 mg/l was used as a selection agent in the medium.

Elemental tracer concentrations of copper, lead, nickel and zinc, were assessed in the muscles of Oreochromis amphimelas and Clarias gariepinus from Lake Manyara, Tanzania, to evaluate their safety to consumers, specifically humans. Results revealed that no elemental concentrations exceeded the FAO permissible levels, indicating fish from all sites are safe for human consumption.

In this study, heavy metal accumulation levels (Cu, Zn, Cr, Pb, As) in biotic [Carassius gibelio (Bloch, 1782), Squalius pursakensis (Hankó 1925)] and abiotic (sediments) components in a significant freshwater ecosystem in Türkiye were investigated on the basis of seasonal variations using geographic information systems (GIS) and some ecotoxicological risk assessment indices [PLI (pollution load index), PERI (potential ecological risk index), Igeo (geo accumulation index), C

To get rid of the singularity of the detection of veterinary drug residues in liquid milk, a high-throughput determination was developed for 126 VDRs in 17 categories in liquid milk based on the one-step extraction coupled with LC-HRMS (UPLC-Q-Exactive-Orbitrap-MS).

Introduction Soil pollution caused by toxic elements such as lead (Pb) and cadmium (Cd) induces environmental stress on vegetable plants and soil microbial communities, reducing crop yield and disrupting ecosystem functions. Methodology In this study, nanoscale zerovalent iron supported with eggshell biochar and activated carbon (nZVI-ESB/AC) was synthesized using ca

Antibiotics are those drugs that can be extracted from some microorganisms and they are effective against other organisms, such as bacteria, by either inhibiting the growth of bacteria or by killing them. The present study was conducted to measure the amount of various antibiotics in the local and imported broiler chickens by using liquid chromatography-mass spectrometry (MS/Q-TOF).

Introduction

While the integrated rice-crayfish (Procambarus clarkii) farming system (IRCFS) is widely developing in China, the widespread use of Unmanned Aerial Spraying Systems (UASS) to protect rice from pests has led to potential pesticide risk for the crayfish in IRCFS. Therefore, it is crucial to examine UASS’s spray deposition and drift in IRCFS.

Abstract Food quality and safety are crucial public health concerns with global significance. In recent years, a series of fluorescence detection technologies have been widely used in the detection/monitoring of food quality and safety. Due to the advantages of wide detection range, high sensitivity, convenient and fast detection, and strong specificity, quantum dot (QD)‐based fluorescent nanosensors have emerged as preferred candidates for food quality and safety analysis.

The field experiments were conducted in a randomised block design during two consecutive rabi seasons of 2016–17 and 2017–18 to evaluate the effect of botanicals and bio-pesticides on insect and mite pests of potato during the post-rainy season.

A piece of carbonized cotton textile (denim) was prepared and shown to be a viable sorbent for the fabric phase sorptive extraction of pesticide residues from various fruit juices. The presented sorbent was made by heating the acidified cotton textile in a furnace.

Potentially Toxic Elements (PTEs) in foods are a threat to global health. This study investigated concentrations of selected PTEs; cadmium, chromium, nickel and lead in fish and cultivated vegetables from and along the dams, respectively. Totally, 84 samples; 60 Tilapia (Oreochromis niloticus), 12 Okra (Abelmoschus esculentus) and 12 Bitter leaf (Vernonia amygdalina) obtained from six dams in Southwestern Nigeria were digested using aqua-regia.

Monascus sp. is an important food microbial resource with the production of cholesterol-lowering agent lovastatin and other healthy metabolites. However, the mycotoxin citrinin naturally produced by Monascus sp. and the insufficient productivity of lovastatin limit its large-scale use in food industry.

The development of different matrix adsorbents is a research focus in the multiresidue analysis of veterinary drugs in foods. In this study, a novel elastic matrix adsorbent based on a reduced graphene oxide-coated melamine sponge was prepared and applied in matrix purification for the simultaneous determination of 52 veterinary drugs in mutton by UPLC–MS/MS. Efficient and convenient matrix removal was achieved through simple soaking and squeezing.

Cadmium-109 whole-body and internal biokinetics were experimentally investigated in critically endangered diamond sturgeon Acipenser gueldenstaedtii after uptake from water or food, in fresh (FW) and brackish (BW; 9‰) salinities typical of the Caspian Sea. Whole-body rates of uptake of 109Cd from water and subsequent depuration were quantified over 14 and 28 days, respectively.

Abstract Genotoxic and hepatotoxic effects of lead (Pb) on a freshwater fish, climbing perch (Anabas testudineus) were studied at an environmentally relevant concentration (43.3 ppm). The genotoxic potential of Pb was confirmed by micronucleus study, with increased frequencies of erythrocytic nuclear alterations like lobed, blebbed, notched, fragmented, and micronuclei were observed in erythrocytes in treated groups as compared to control.
