In recent decades, independent national and international research programs have revealed possible reasons behind the death of managed honey bee colonies worldwide. Such losses are not due to a single factor, but instead are due to highly complex interactions between various internal and external influences, including pests, pathogens, honey bee stock diversity, and environmental changes. Reduced honey bee vitality and nutrition, exposure to agrochemicals, and the quality of colony management contribute to reduced colony survival in beekeeping operations. Our Special Issue (SI) on ‘’Monitoring of Honey Bee Colony Losses” aims to address the specific challenges that honey bee researchers and beekeepers face. This SI includes four reviews, with one being a meta-analysis that identifies gaps in the current and future directions for research into honey bee colonies’ mortalities. Other review articles include studies regarding the impact of numerous factors on honey bee mortality, including external abiotic factors (e.g., winter conditions and colony management) as well as biotic factors such as attacks by Vespa velutina and Varroa destructor.

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.

How many times have we thought with concern about the possible contamination of food? Pollution, agricultural treatments, technological treatments, and packaging are the best-known human sources of toxic substances as food contaminants. The present book contains 11 original research papers representing various approaches of identifying and measuring toxic residues in food materials. The analytical determination of food contaminants is an indispensable tool in characterizing the adverse effects and unexpected toxicity related to food intake. No risk assessment would be possible without data from the analysis of food contaminants. This Special Issue is an interesting overview of recent methods and is highly representative of a broad worldwide outline, collecting authors from ten different countries and four continents. Very different toxics are described, from volatile organic compounds to heavy metals and from highly polar chemicals to classical organic contaminants. A wide range of analytical techniques are portrayed, including sample preparation and clean-up methodologies, classical chromatographic and hyphenated spectroscopies, and the latest high-resolution mass spectrometry applications. The presented works consider a varied selection of foods: the studied matrices are meat, fishery products, fruits, and miscellaneous beverages.
