Occurrence, Toxicity & Analysis of Toxic Compounds in Oceanic Biota


Book Description

The presence of concentrations of organic substances and cations in sea water is a matter of increasing concern to the water industry, environmentalists and the general public alike. There is a threat of possible health hazards to both human, fish and crustacea. Occurrence, Toxicity and Analysis of Marine Biota discusses bioaccumulation in biota as well as occurrence and analysis of toxicants in biota. The main thrust of this book will be a review of the levels of toxicants found in the tissues of fish and invertebrates at various sites throughout the world. In addition, results will be reported on the levels of toxicants found in marine biota enabling ill health or death to occur. This will involve a discussion of toxicity index LC50 and percentile S95 concentration of toxicants and their implications on animal health and mortality, also that of humans who eat these sea creatures. The book will be a complete logical survey of this topic.




Occurrence, Toxicity & Analysis of Toxic Compounds in Oceanic Biota


Book Description

A welcome contribution to the recent concerns with the effects of new threats to oceanic ecosystems. There is much justified concern regarding the state of the world’s oceans and the book addresses significant aspects related to their health. The first step in dealing with pollution is to know what is there and how much of specific pollutants and classes of pollutants are present. This book summarizes this information. Highly experienced author in the field. Broad audience.




Water Pollution and Remediation: Organic Pollutants


Book Description

Wastewater pollution is a major issue in the context of the future circular economy because all matter should be ultimately reused, calling for efficient depollution techniques. This book present timely reviews on the treatment of wastewater contaminated by organic pollutants, with focus on aerobic granulation and degradation. Organic pollutants include microplastics, phthalates, humic acids, polycyclic aromatic hydrocarbons, pharmaceutical drugs and metabolites, plastics, oil spills, petroleum hydrocarbons, personal care products, tannery waste, dyes and pigments.




Toxicants in the Aqueous Ecosystem


Book Description

This book provides a complete coverage of all aspects of the occurrence, toxicity and analysis of toxicants in the aqueous ecosystem. The aqueous ecosystem includes natural waters such as rivers, coastal waters and open seawater. It also includes sedimentary matter present in these waters, creatures (fish, crustacea) and plant life. Chapters dealing with toxicity measurement, control of pollution regulation and toxicity data systematically discuss metals, organometallic compounds and organic compounds. In addition, Chapters 4 and 5 deal with the effects of these types of toxicants in natural waters and water creature?s tissues, whilst Chapter 8 deals with the health of such creatures. Contents: Toxicity Evaluation - Water Based Toxicity Evaluation - Animal Tissue Analysis Based Control of Pollution Regulations Toxicity Data Effects of Dissolved Metals in Water on Creatures Effect of Organic and Organometallic Compounds in Water on Creatures Pollution of Sedimentary Matter Polution of Sea Organisms Phytoplankton Algae and Weeds - Toxicity, Concentration and Analysis Pollution of Potable Water Radioactivity in the Environment Toxicants in the Aqueous Ecosystem is essential reading for all Analytical Chemists, Environmentalists and Toxicologists working in the field.




Chemistry of Marine Water and Sediments


Book Description

The most important processes on the Earth`s surface occur in the Ocean where materials and energy are primarily exchanged. In the case of marine chemistry different fields of chemistry from organic to inorganic as well as thermodynamics and biochemistry are involved. Analytical Chemistry is a very important tool for the quantification of biogeochemical processes by providing correct and even more sophisticated methodologies. These are often directly applied 'in situ', in order to detect trace and ultra-trace natural and anthropogenic substances. Kinetic and thermodynamic studies allow us to establish whether the process occurs. Once discovered it is then possible to build up general models for environmental systems. This book gathers many aspects with the aim of creating a general picture of the chemical processes occurring in the marine environment




Pesticides in Stream Sediment and Aquatic Biota


Book Description

More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction,













Oil in the Sea III


Book Description

Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
