New Challenges In Marine Pollution Monitoring

Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.

The study of marine environments inevitably involves considering the problem of marine pollution, which includes questions that focus on the essential need to ensure the long-term health of these exceptional ecosystems and the lives and livelihoods they support. The open access textbook "Marine Pollution: monitoring, management and mitigation" approaches these questions in a practical and highly readable format. It gives newcomers to the field background and perspective through the first comprehensive, multidisciplinary exploration of the topic. The topic is indeed complex, requiring the integration of the natural sciences and chemistry with management, policymakers, industry and all of us who are users of the marine environment. The textbook was written by leading experts to especially prepare graduates for a career in marine pollution studies. At the same time, it is relevant for anyone invested in the marine environment with a will to reduce their impacts. The chapters can easily be used independently and are also connected through the cross-referencing of related content. The introductory chapter provides a historical account of marine pollution and explores the fundamental physicochemical conditions of seawater. Two full chapters cover the requisite resources for ensuring success in field and laboratory studies. Then, chapter by chapter the book dives into to the various types of marine pollutants. In closing, it discusses the challenges of understanding multiple stressors and presents mitigation and restoration practices, along with a global overview of marine pollution legislation. We envisioned this textbook as being open access for the very reason we created it: this topic calls for global contributions and champions, and financial restraints should not limit access to this knowledge.

Contaminants of emerging concern in the marine environment: current challenges in marine pollution reviews the available data in relation to contaminants of emerging concern (CECs) in the marine environment: main sources, transport pathways, distribution in seawater and sediments, bioaccumulation, and biological effects. Each chapter recaps the most relevant information about the main groups of CECs, describing the particularities and specificities of each group and focusing on the most relevant individual contaminants. CECs are not regulated substances, and therefore not considered in national and international monitoring programs, even though they may have a potential impact on the environment due to their continuous input, relative persistence, and/or toxicity. CECs are relevant not only in continental and coastal areas close to their main sources, but also in the open sea, because some of them are likely to be transported long distances through air deposition or absorbed into particulate material. The persistence of many degradable substances in the marine environment increases when they are absorbed into particulate material/sediments and/or when they are subjected to anaerobic conditions that slow down the degradation kinetic of many contaminants. Bioaccumulation of several CECs has been confirmed in different coastal organisms; however, in general, the information available (species and trophic levels considered) is very limited because most studies are mainly focused on specific coastal areas. This book offers useful information about not regulated contaminants that are not considered in international monitoring programs but have potential impacts in coastal and open-sea areas. Therefore reading the book will allow them to improve their view about the real impact of current-use contaminants in the marine environment. Presents a comprehensive view of the most relevant groups of CECs Includes an overview of each group of CECs, including uses, properties, analysis, distribution, bioaccumulation, and effects Provides information on all environmental compartments and marine areas (coast, continental shelf, and open sea)

Marine Environments: Diversity, Threats and Conservation presents important challenges and advances in the field of marine bioindicators in recent years, which could be relevant for integrative monitoring purposes and the development of new approaches and technologies in marine pollution monitoring.The authors describe history of the development of organophosphorus pesticides, their behavior, currents concentrations in marine environments, and effects on marine biota.The environmental behavior of organochlorine pesticides is reviewed, along with their effects on biota in global marine coastal environments, noting that these compounds are still detectable and potentially harmful.In one study, stranded cetaceans and Pacific cods are used as indicator species to compare the contamination levels of radiocesium in three seas shortly after the Fukushima Daiichi Nuclear Power Plant Accident in 2011.A comparison between different extraction and detection techniques used for the determination of organic and inorganic pollutants in environmental matrices such as biota, water, and sediment is investigated.Additionally, the authors address the influence of plastic pollution on marine environments through continental water bodies.The potential application of the UV/persulfate process for the degradation of emerging organic pollutants in seawater is discussed, using chlorazol black as a substrate model. The implications of atmospheric transport in the circulation of organochlorine pesticides are considered, presenting the relevance of atmospheric deposition to the oceans as a key process that affects marine environments.The penultimate chapter assesses the health of Black Sea fish species belonging to different ecological groups. In particular, the hystopathological and biochemical biomarkers of the blood, spleen and liver are studied.In closing, the authors propose a Containerized Marine Knowledge System by means of IoT-Cloud and LoRaWAN to improve marine environment monitoring.
