The purpose of this study was to investigate the association among polycyclic aromatic hydrocarbons (PAHs) exposure and air pollutants and the diversity of microbiota. Daily average concentrations of six common air pollutants were obtained from China National Environmental Monitoring Centre.

A dispersive liquid–liquid micro-extraction method was combined with high-performance liquid chromatography to rapidly and efficiently separate and detect organophosphorus pesticide residues in coarse cereals. In order to select the best conditions, the extraction conditions, including the type and volume of the extraction agent, the type and volume of the dispersant, extraction time, pH, and the amount of NaCl, were optimized.

The Strategic Alliance for Research into Infectious Diseases of Animals and Zoonoses (STAR‐IDAZ) International Research Consortium (IRC) coordinates global animal health research to accelerate delivery of disease control tools and strategies. With this vision, STAR‐IDAZ IRC has constructed four generic research roadmaps for the development of candidate vaccines, diagnostic tests, therapeutics and control strategies for animal diseases.

Increasing contamination of urban soil by persistent organic pollutants is a major environmental issue. The purpose of the present study was to investigate the distribution, source and human health risk of polycyclic aromatic hydrocarbons (PAHs) in different functional areas in Zhengzhou City, China. Total 130 soil samples were collected from surface layer (0–10 cm) in urban road, overpass, residential area and park in the city during January 2019.

Chemical agricultural inputs (e.g. pesticides and fertilizers) pollute the environment and undermine food safety. In fact, agriculture is in a direct relationship with the environment and farmers’ behaviours have extensive positive or negative impacts on it. Therefore, enhancing farmers’ behaviours to go towards organic farming methods represents a promising approach.

Background Endocrine disrupting chemicals (EDCs), proved to be potential carcinogenic threats to human health, have received great concerns in food field. It was essential to develop effective methods to detect EDCs in food samples.

Quorum sensing (QS) is a mechanism of intercellular communication in bacteria that received substantial attention as alternate strategy for combating bacterial resistance and the development of new anti-infective agents. The present investigation reports on the assessment of using subinhibitory concentrations of antibiotics for the inhibition of QS-regulated phenotypes in Chromobacterium violaceum.

Abstract

Main conclusion

Activation of GPX and enhanced NO level play a key role in IBA-mediated enhanced Cd tolerance in young barley roots.

Yeast extract (YE) is tremendously used as a flavor enhancer in foods because of its composition. However, different types of YE have different aromatic profiles. This study focuses on the thermal treatment of glutathione-enriched yeast extract (GSH-YE) at different temperatures with the addition of Maillard precursors to investigate any change in its volatile organic profile. Headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS) was utilized for the instrumental analysis.

The novelty of this research work lies in a simple, fast, and plausible analysis of acrylamide in food samples accomplished using an iOS gadgets–based digital imaging colorimeter (iOS gadgets–based DIC).

Cadmium (Cd) is a toxic heavy metal with no known biological functions in the human body. Due to a considerably long biological half‐life and very low rate of excretion, accumulation of Cd in different body organs (eg, liver, kidney, and testes) over time is associated with perturbed functioning of these organs. Recent studies have shown the extreme sensitivity of the testes to Cd toxicity.

Background Low adoption of maize varieties bred to address the nutritional needs of the growing African population limits their impact. Aroma is essential in consumer preference, but has hitherto hardly been studied. We analysed the volatile organic compounds of flours and porridges of 22 maize varieties belonging to four nutritionally distinct groups, namely provitamin A maize, quality protein maize, yellow and white maize.

In this study, the optimum conditions for manufacturing particleboard-based waste cotton stalks were evaluated to achieve a good performance of mechanical properties. The response surface methodology (RSM) is used to calibrate the experiment results based on input variables consisting of the weight ratio of melamine formaldehyde to urea-formaldehyde (MU) resins, shelling ratio (SR), and the proportion of cotton particles to poplar particle (CP) in the core layer.

Lead is a metal capable of affecting physiology and metabolism in fish, including Nile tilapia (Oreochromis niloticus). However, few studies have evaluated the effects of lead on digestive enzyme activities in fry. At that stage, independent feeding begins, and there is increased demand and consumption of food, so chronic exposure to metal during this stage of development would cause null or minimal growth in organisms.
