Available in PDF, EPUB and Kindle. Book excerpt: Environmental fate and effect of ZPT, a booster biocide in anti-fouling paints for boats has been studied. Using a new analytical method for simultaneous determination of zinc- and copper pyrithione (ZPT/CPT) showed that up to 50% of added nominal ZPT was tranchelated to CPT at ambient seawater copper concentrations. Both compounds are photodegradable, with half-lives between 7 to 45 minutes depending on light intensities. At lower light intensities, i.e. in natural waters containing organic matter, and in the dark, the compounds are stable for > 48 hours. The toxicity of ZPT and CPT varied between EC50-values of 1.6-60 nM for pelagic bacteria, algae and zooplankton communities. ZPT and CPT affected the benthic community nutrient cycling at concentrations over 0.001 nmol/g dry sediment, especially cycling of nitrogen. Since ZPT in boat-paint will be tranchelated to the more stable, and for the pelagic community more toxic compound CPT when released into the marine environment, CPT should be included in future risk assessment of ZPT.

Download or read book Advances in Marine Antifouling Coatings and Technologies written by Claire Hellio and published by Elsevier. This book was released on 2009-05-22 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biofouling can be defined as the undesirable accumulation of microorganisms, algae and animals on structures submerged in seawater. From the dawn of navigation, marine biofouling has been a major problem for shipping in such areas as reduced speed, higher fuel consumption and increased corrosion. It also affects industries using off-shore structures such as oil and gas production and aquaculture. Growing concerns about the environmental impact of antifouling coatings has led to major new research to develop more environmentally-friendly alternatives. Advances in marine antifouling coatings and technologies summaries this wealth of research and its practical implications. This book is divided into four sub-sections which discuss: marine fouling organisms and their impact, testing and development of antifouling coatings, developments in chemically-active marine antifouling technologies, and new surface approaches to the control of marine biofouling. It provides an authoritative overview of the recent advances in understanding the biology of fouling organisms, the latest developments on antifouling screening techniques both in the field and in the laboratory, research on safer active compounds and the progress on nontoxic coatings with tailor-made surface properties. With its distinguished editors and international team of contributors, Advances in marine antifouling coatings and technologies is a standard reference for manufacturers of marine antifouling solutions, the shipping industry, oil and gas producers, aquaculture and other industries using offshore structures, and academics researching this important area. Assesses marine antifouling organisms and their impact, including a historical review and directions for future research Discusses developments in antifouling coatings examining chemically-active and new surface approaches Reviews the environmentally friendly alternative of safer active compounds and the progress of non-toxic compounds
Download or read book Biofouling written by Simone Dürr and published by John Wiley & Sons. This book was released on 2009-12-21 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofouling (the colonisation of an interface by a diverse array of organisms) is almost always a problem where it occurs, as it negatively affects surfaces, the materials that they are made from and the structures that they form, and can even destroy them. This comprehensive book covers in detail in its first section the processes involved in marine , freshwater and medical biofouling including coverage of settlement by larvae and spores, biofouling community processes, epibiosis (biofouling on living organisms) and microbial fouling, including biofilms deleterious to human health. The book's second section, encompassing biofouling processes with industrial implications, includes coverage of biofouling on artificial substrata, paints and coatings technology for the control of marine biofouling, biofouling and antifouling in the maritime industries, such as shipping, offshore oil , and aquaculture, and in power stations and other industries. The impacts of both biofouling and biofouling control and details of current legislation of relevance to biofouling issues are fully covered. The book's final section looks at methods for the measurement of biofouling, and future prospects for biofouling, including in-depth coverage of the changes anticipated in biofouling worldwide due to global climate change, and likely future directions in antifouling research, technology and legislation. Biofouling, which includes contributions from many international experts, is an essential reference for all those working in the antifouling industry including those involved in formulation of antifouling products such as paints and other coatings. Aquatic biologists, ecologists, environmental scientists and lawyers, marine engineers, aquaculture personnel, chemists, and medical researchers will all find much of interest within this book. All universities and research establishments where these subjects are studied and taught should have copies of this important work on their shelves.

Download or read book Ecotoxicology of Antifouling Biocides written by Takaomi Arai and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organotin compounds, used as antifouling biocides since 1960, are chemical compounds that act as endocrine disrupters. It is not known how organotin compounds cause hormone disturbance, however, and many questions remain about their effect on aquatic organisms. Studies on organotin compounds have recently evolved, with many new findings reported. Following a worldwide ban on organotin compounds in 2008, alternative compounds will mainly be used, with the potential for coastal areas to become contaminated, causing, among other effects, cholinesterase inhibition in aquatic organisms. Use of alternative compounds must be controlled to avoid such errors. These and other findings are described and concisely summarized in this book, providing a useful reference in countries where alternative biocides are being considered. Included are studies on the effects on marine organisms, making this book an excellent aid to experts in environmental chemistry, to government organizations, and to students.

This book was released on 2011-09-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Impacts of Toxic Chemicals presents a comprehensive, yet readable account of the known disturbances caused by all kinds of toxic chemicals on both aquatic and terrestrial ecosystems. Topics cover the sources of toxicants, their fate and distribution through the planet, their impacts on specific ecosystems, and their remediation by natural systems. Each chapter is written by well-known specialists in those areas, for the general public, students, and even scientists from outside this field. The book intends to raise awareness of the dangers of chemical pollution in a world dominated by industry and globalization of resources. Because the problems are widespread and far reaching, it is hoped that confronting the facts may prompt better management practices at industrial, agricultural and all levels of management, from local to governmental, so as to reduce the negative impacts of chemical contaminants on our planet.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Microbicides for the Protection of Materials written by W. Paulus and published by Springer Science & Business Media. This book was released on 1993-09-30 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is chiefly intended for those who are using microbicides for the protection of materials. Another purpose is to inform teachers and students working on biodeterioration and to show today's technical standard to those engaged in R&D activities in the microbicide field. When trying to classify, or to subclassify, material-protecting microbicides according to their mode of action, e.g. as membrane-active and electrophilic active ingredients, it turned out that a clear assignment was not always possible. For that reason the author has resorted to chemistry's principle of classifying according to groups of substances (e.g. alcohols, aldehydes, ketones, acids, esters, amides, etc.), thus providing the first necessary information about the micro bicides' properties. The description of the various groups of substances includes, whenever possible, an outline of the mode and mechanism of action of the active ingredients involved. The effective use of microbicides presupposes knowledge of their character istics. That is why the microbicides' chemico-physical properties, their toxicity, ecotoxicity, effectiveness, and effective spectrum are described in greater detail. As mentioned before, the characteristics of microbicides play an important role. They have to be suited to the intended application to avoid detrimental effects on the properties and the quality of the material to be protected; also production processes in which microbicides are used to avoid disturbances by microbial action must not be disturbed by the presence of those microbicides.
