Book Description
Environmental pollution has been a challenging phenomenon in most developing countries, due to the weak enforcement of environmental regulations. As a result, humans and animals are exposed to different environmental pollutants, which threaten their very existence. Some of the emerging pollutants of great concern are polybrominated diphenyl ethers (PBDEs) since they are categorized as probable human carcinogens and are also known to bioaccumulate in fatty tissues of animals and humans, reaching toxic levels upon continued exposure. Monitoring of these pollutants is therefore paramount as it contributes to addressing the problem of human exposure and environmental pollution. Their monitoring involves sample preparation methods followed by quantification with various detection techniques. Sample preparation methods that aim at reducing matrix interferences, enriching analytes and transfer of analytes to a desirable solvent, have evolved from conventional methods to advanced methods that facilitate the detection of these chemicals at very low concentrations. Likewise, detection techniques have advanced from chromatographic detection techniques to miniaturized systems that involve sensors. This chapter discusses PBDEs as emerging pollutants, their sources, and toxicological implications on humans, as well as advances in sample preparation methods and detection techniques in the determination of PBDEs.

Book Description
Emerging Contaminants presents the reader with information on classification, recent studies, and adverse effects on the environment and human health of the main classes of contaminants. Emerging contaminants are synthetic or natural compounds and microorganisms produced and used by humans that cause adverse ecological and human health effects when they reach the environment. This book is organized into four sections that cover the classification of contaminants and the instrumental techniques used to quantify them, recent studies on pesticides, antibiotics as an important group of emerging contaminants, and studies of different classes of emerging contaminants such as polybrominated diphenyl ethers (PBDEs), microplastics, and others.

Book Description
Ultraviolet LED Technology for Food Applications: From Farms to Kitchens examines the next wave in the LED revolution and its ability to bring numerous advantages of UVC disinfection. As UVC LED-based light fixtures will become the driving force behind wider adoption, with potential use in the treatment of beverages, disinfection of food surfaces, packaging and other food contact and non-contact surfaces, this book presents the latest information, including LEDs unique properties and advantages and the developments and advances made in four areas of application, including produce production and horticulture, post-harvest and post processing storage, safety and point-of-use applications. Alternative opportunities to current practices of food production and processing that are more sophisticated and diverse are being intensively investigated in recent decades, things like Ultraviolet light (UV) irradiation. The effects of UVC LEDs against bacteria, viruses and fungi already have been demonstrated and reported, along with the first applications for disinfection of air, water and surface made for the "point-of-use" integration. - Brings unique advantages of LEDs for foods from farm to kitchens - Explores applications and advances in LEDs for horticulture, crops production, postharvest reservation and produce storage - Investigates UV LEDs in food safety
