    The purpose of this Special Issue is to bring together research and review papers that use radiopharmaceuticals in drug development. Labeling a potential drug with a radionuclide for imaging and injecting radiopharmaceuticals into animals or humans can immediately provide information about the in vivo destiny of the compound through the application of PET or SPECT scanners. Radionuclides can be useful throughout the whole process of developing new drugs; in particular, if the results obtained are negative and the potential drug can be discarded early on in the process, considerable effort and money can be saved. An alternative way to obtain information about the in vivo destiny/effect of a potential drug is to imagine, for example, a target organ or a tumor with radiopharmaceuticals before and after treatment with a drug. Determining how a drug is metabolized is an integrated part of drug development. Labeling a drug with a radionuclide and providing it with a radioactive tag can help in subsequently determining its location and quantifying metabolites. If the metabolites can be extracted, the solutions can be examined through analytical measurements. Using ionizing radiation in the treatment of tumors is also an application for radiopharmaceuticals which is expected to expand greatly in the years to come. By labeling a specific compound with a radionuclide used for diagnostics we can establish whether it accumulates in the tumor. The same compound is thereafter combined with a radionuclide for treatment.This Special Issue contains seven original research papers, one communication, and two reviews.

    This book covers cadmium contamination of soil and plants, its sources, acute and long-term impacts on the environment and human health, and overall challenges posed by the global poisoning issue. Cadmium is among the elements that have been most broadly used by man over time, which has led to extensive pollution of surface soils, mainly associated with the mining and smelting of the metal and the addition of organic cadmium compounds to petrol. The release of cadmium into the atmosphere from various high-temperature processes has also led to surface contamination on a regional and even global scale. Cadmium is particularly firmly bound to humic matter in organic-rich soil and to iron oxides in mineral soil and is rather immobile in the soil unless present at very high concentrations. Plants grown on cadmium-rich soils incorporate cadmium, thus increasing the concentration of cadmium in crop plants. Cadmium thus enters the food chain through the consumption of plant material, whichposes important health risks to humans and animals. In this book, readers will find out about the latest mitigation strategies, including a multi-disciplinary approach to address cadmium contamination. Recent methods in cadmium detoxification, speciation, and molecular mechanisms are included, and the book offers the knowledge required for efficient risk assessment, prevention, and countermeasure. Divided into 3 parts, this book brings together expert contributions on cadmium toxicity. In the first part, readers will find out about the different sources and distribution of cadmium in soil and plant ecosystems. The second part of the book outlines the health risks linked to cadmium toxicity, and in the final part, readers will discover sustainable cadmium toxicity mitigation strategies and potential applications of recent biological technology in providing solutions. This book is a valuable resource for students, academics, researchers, and environmental professionalsdoing fieldwork on cadmium contamination throughout the world.
