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).

by Erin A. Hull, Rebekah R. Stiling, Marco Barajas, Rebecca B. Neumann, Julian D. Olden, James E. Gawel Lake sediments store metal contaminants from historic pesticide and herbicide use and mining operations. Historical regional smelter operations in the Puget Sound lowlands have resulted in arsenic concentrations exceeding 200 μg As g-1 in urban lake sediments.

by Shary Tamara Schneider, Rudi Isbrandt, Heidrun Gehlen, Nina Langkabel, Diana Meemken The ‘positive list for equines’ (Regulation (EC) No 1950/2006) was implemented in the European Union in 2006. The drugs listed are approved for use in slaughter equines under certain conditions, although those drugs are not approved for use in livestock and are not listed in Table 1 of the annex to Regulation (EU) No 37/2010.

This study aims to provide insights into the current status of pesticide residue contamination in Hainan province and to develop food safety regulations for controlling the excessive use of pesticides on cowpea. First, to assess the dietary exposure risks of pesticide residues in Hainan cowpea, more than 340 pesticides in 80 different fresh cowpea samples were investigated by HPLC-Q-TOF/MS/MS.

Cadmium (Cd) exposure has been associated with the development of enterohepatic circulation disorders and hyperuricemia, but the possible contribution of chronic low-dose Cd exposure to disease progression is still need to be explored.

Background Seaweed, or macroalgae has traditionally been part of the Asian cuisine for decades and is also becoming increasingly popular as food source in Europe and other Western countries. However, seaweed can accumulate elements from the environment and consequently may be a source of exposure to toxic elements, or potentially harmful levels of micronutrients.

Mercury (Hg) is a global environmental concern due to its toxicity (especially high in methylated form) and the long-range distribution of its gaseous elemental form (GEM). Hg-contaminated areas, such as abandoned mining sites, pose intrinsic difficulties for their management and heavy monitoring costs. In these environments, plant-based solutions may play a key role in the ecosystem quality assessment and support remediation strategies, combining reliability and cost-effectiveness.

Cadmium (Cd) contamination in wheat fields has become a major environmental issue in many regions of the world. Mercapto-palygorskite (MPAL) is a high-performance amendment that can effectively immobilize Cd in alkaline wheat soil. However, MAPL as an in-situ Cd immobilization strategy for alkaline wheat soil remains to be evaluated on a field-scale and the underlying mechanisms requires further evaluation.

To understand the effects of mining activities on soil cadmium and rice, a typical mining area was selected. The Cd content in a considerable number of soils exceeded the standard limitation GB/T 36,783 − 2018, with a rate of 42.03%. Further analysis revealed soil total Cd content was strongly correlated with soil bioavailability of Cd (R2 0.721**), pH (R2 0.386**) and soil total content of lead(R2 0.678**).

Food chain contamination by soil lead (Pb), beginning with Pb uptake by leafy vegetables, is a threat to food safety and poses a potential risk to human health.

Tetrabromobisphenol A (TBBPA) and lead (Pb) are widely used in industrial field, which poses a serious threat to human and animal health. In particular, a large volume of wastewater containing TBBPA and Pb was discharged into the aquatic environment, causing a seriously negative impact on fish. Currently, whether TBBPA and Pb have a synergistic toxicity on fish remains unclear.

Abstract Fluoroquinolones are commonly used in poultry breeding. Few studies have evaluated the causes of serious drug residues in black‐boned silky fowl until enrofloxacin has been banned in black‐boned silky fowl breeding in the Chinese Veterinary Commission of Chinese Veterinary Pharmacopoeia (2020). However, similarly structured fluoroquinolones have not been studied in black‐boned silky fowl.

Abstract Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of sodium hydroxide as a technological additive (acidity regulator) for dogs, cats and ornamental fish. The applicants have provided evidence that the additive currently on the market complies with the existing conditions of authorisation.

Soil microorganisms play a crucial role in remediating contaminated soils in modern ecosystems. However, the potential of combining microorganisms with legumes to enhance the remediation of heavy metal-contaminated soils remains unexplored. To investigate this, we isolated and purified a highly efficient cadmium and lead-tolerant strain. Through soil-cultivated pot experiments with two leguminous plants (Robinia pseudoacacia L.

Introduction

Approximately 200 million people worldwide are affected by arsenic toxicity emanating from the consumption of drinking water containing inorganic arsenic above the prescribed maximum contaminant level. The current investigation deals with the role of prenatal arsenic exposure in modulating the gut microbial community and functional pathways of the host.

Method

A dual-mode sensing platform for Pb2+ was constructed based on the dual optical channels of Au NPs system with the amplification of DNAzyme, and it was successfully applied for Pb2+ determination in preserved egg with satisfactory results. The presence of Pb2+ activated the DNAzyme and induced the dispersion change of Au NPs in high salt concentration.

Vegetable cultivation on solid wastes dumpsites (SWD) soils is very common in developing countries though unsafe due to heavy metals pollution. In order to evaluate the ecological and human health risks of this practice, Talium triangulare and Lycopersicon esculentum were grown in a greenhouse on soils from two abandoned and active SWD, and control site.

The heavy-metal-associated (HMA) proteins are a class of PB1-type ATPases related to the intracellular transport and detoxification of metals.
