Content: This open access book distinguished itself from other publications by offering step-by-step instructions on how to extract, purify, provide modifications, and major issues to be encountered during the process. For the δ18OP method to progress, further fundamental research as well as field and laboratory studies need to be conducted for a better understanding of P cycling in the environment. Chapter 1 outlines the background and examples of δ18Op studies in sediments, soils, fresh water, mineral fertilizers, and plants. Chapters 2 and 3 examine the stepwise extraction and purification protocols including reagents, equipment and consumables and preparations for analyses. Chapter 4 examines some of the challenges and modifications during the purification process. Chapter 5 discusses planning and designing of a study using δ18Op, external quality assurance with an example of an inter-laboratory study. Chapter 6 outlines the conclusions, future trends, and opportunities, the scaling out of the method from laboratory to field studies. It is expected that the δ18OP would be extensively applied in research geared to understand phosphorus dynamics in different agro-environments

Content: The objective of this open access book is to present protocols, methodologies, and standard operating procedures (SOPs) used for the identification of sources, transport, and fate of agro-contaminants and illustrate them with several case studies of successful applications. The Soil and Water Management & Crop Nutrition (SWMCN) Subprogramme of the Joint Food and Agriculture Organization (FAO)/International Atomic Energy Agency (IAEA) Centre of Nuclear Techniques in Food and Agriculture, through a Coordinated Research Project (CRP) in partnership with national and international research institutes, developed and evaluated a set of analytical techniques (the toolbox). The toolbox integrates multiple isotope tracers that provide information on the origins and pathways of multiple pollutants through agro-ecosystems, thereby providing more accurate guidance on mitigations. However, land management strategies to address and control the transport of pollutants from soil to water bodies remain the shared responsibility of farm and aquaculture operators, agro-chemical manufacturers, and policymakers in food and agriculture as well as the mining sectors. This book is structured into eight chapters covering (i) an overview of the book's content, (ii) guidelines for designing water sampling programmes, (iii) the use of mixing models applicable to tracers for water pollution studies, (iv) compound-specific isotope analyses to investigate pesticide degradation in agricultural catchments, (v) the use of stable oxygen isotope composition of phosphate to investigate phosphorous in soil-plant continuum, (vi) the use of stable sulphur isotopes to disentangle agro-pollutants from other contaminants, (vii) nuclear tools used in sediment source apportionment, and (viii) the conclusions and perspectives forward. The book offers up-to-date information, and we hope it is a great source of information for students, researchers, and policymakers. The SWMCN subprogramme thanks all the contributors involved in the preparation of this publication.
