Abstract:
... Foodborne viral diseases are a major public health problem that poses significant social and economic strains. Human astrovirus (AstV), norovirus (NoV), human rotavirus (RoV), and hepatitis A virus (HAV) are frequently reported foodborne pathogens. The microarray is a molecular diagnostic method that is highly specific and widely used due to its plethora of applications in microbiology. This inves ...

adulterated products; ephedrine; ergogenic aids; liquid chromatography; magnetism; mass spectrometry; monitoring; solid phase microextraction; sports; weight control; weight loss; Iran
Abstract:
... Sport supplements and weight management supplements are prime targets for adulteration. In response to concerns regarding the safety of ephedra-containing food supplements, manufacturers have marketed “ephedra-free” products. Therefore, a rapid and convenient magnetic dispersive solid phase microextraction method is proposed in order to extract ephedrine from complex food supplements. Quantificati ...

Eriocheir sinensis; carbon; consumer preferences; crabs; diet; ecosystems; environmental factors; lakes; nitrogen; nutritive value; odors; stable isotopes; stakeholders; taste; trophic levels
Abstract:
... The Chinese mitten crab (CMC) is an economically important species that consumers prefer mainly because of its delightful taste and aroma. The taste of CMC varies depending on its environmental conditions. Consumers prefer lake-sourced crabs to pond-cultured ones, but the production of crabs in lakes is greatly discouraged because of its adverse impacts on the local ecosystem. This study investiga ...

Abstract:
... The occurrence of 16 polycyclic aromatic hydrocarbons (PAHs) in 68 brands of teas, bought in Poland, was surveyed using ultrasonic extraction of dried teas and liquid–liquid extraction of infusions. The extracts were cleaned by solid phase extraction. The instrumental analysis was performed using gas chromatography coupled with mass spectrometry (GC–MS). The total content of 16 PAHs (∑16PAHs) rang ...

Abstract:
... In recent years, food safety and environmental concerns became a significant issue, especially in developing countries. Pesticides have been applied broadly in agriculture to enhance the production and quality of the agricultural products and in order to decrease the energy cost. Pesticides are non-biodegradable chemical compounds and commonly used in agriculture for pest control and to increase y ...

Abstract:
... We developed an analytical method for quantifying clothianidin residues in green bean, pepper and watermelon crops using dispersive liquid-liquid microextraction (DLLME) and liquid chromatography-tandem mass spectrometry; this method was more rapid, sensitive and simple than QuEChERS sample preparation. Method validation indicated that the recovery for clothianidin was 80.8–93.1%, intra-day and in ...

Abstract:
... Impacts of neonicotinoid-containing pesticides on pollinators have been heavily debated in recent years. While bees in the field get rarely exposed to lethal concentrations of neonicotinoids applied as seed coating, sublethal levels found in pollen and nectar may affect bee population development. We assessed a realistic and a worst-case scenario of clothianidin exposure to mason bees (Osmia bicor ...

Subject:
beets; bolting; clothing; fungicides; leaves; pesticide application; pesticide residues; plant protection; risk assessment; sugar beet
Abstract:
... Plant protection products often leave external residues on crops. Workers can be exposed to these residues when re-entering a recently-treated crop. Therefore, task- and crop-specific transfer coefficients are used to estimate the exposure of workers during re-entry: these relate to the transfer of foliar residues to clothing or skin. In this study, we considered a re-entry task not currently cove ...

Abstract:
... In agricultural crops, honey bees may be exposed to multiple pesticides. However, in field realistic conditions mixtures of products classified as harmless to bees can lead to a synergistic increase of toxicity on honey bees, as known for ergosterol biosynthesis-inhibiting (EBI) fungicides combined with pyrethroids or neonicotinoids. For substances like fertilizers, usually no information on poten ...
