Contamination of the aquatic environment by antifouling compounds has been a topic of increasing importance during the last few years. This book describes advances in antifouling paint biocides, and provides thorough evaluation of research and information on occurrence and levels, environmental fate, analytical techniques and methods for the monitoring and control, environmental modeling, ecotoxicological effects and risk assessment placing emphasis on the knowledge acquired over the last decade.
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.
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
This book reviews the development of antifouling surfaces and materials for both land and marine environments, with an emphasis on marine anti biofouling. It explains the differences and intrinsic relationship between antifouling in land and marine environments, which are based on superhydrophobicity and superhydrophilicity respectively. It covers various topics including biomimetic antifouling and self-cleaning surfaces, grafted polymer brushes and micro/nanostructure surfaces with antifouling properties, as well as marine anti biofouling. Marine anti biofouling includes both historical biocidal compounds (tributyltin, copper and zinc) and current green, non-toxic antifouling strategies. This book is intended for those readers who are interested in grasping the fundamentals and applications of antifouling.

Nanomaterials and nanocomposite materials have been developed as corrosion inhibitors and are the most noble and effective alternatives to traditional organic corrosion inhibitors. Nanomaterials provide reasonably high anticorrosive activity in both aqueous and solution phases. A unified approach to this task is lacking, however, which highlights the role of all disciplines involved in the creation and use of corrosion protection coatings for metals. Fouling is the process of accumulating unwanted material that is mostly non-living and comprised of detritus and organic or inorganic compounds, or organisms, such as tiny viruses up to giant kelps. This book covers both the processes of biofouling and anti(bio)fouling, and the devices that stop the biofouling process. This book provides a missing synopsis by providing an understanding of the anticorrosive and anti-biofouling effects of nanomaterials and nanocomposites under different environments. It features an up-to-date picture of the quality and chemistry of a substrate surface, its proper preparation by conversion treatment, the function of resins and anticorrosive pigments in paints, and novel concepts for corrosion protection.
The rapid increase in the emergence of antibiotic-resistant bacterial strains, combined with a dwindling rate of discovery of novel antibiotic molecules, has created an alarming issue worldwide. Although the occurrence of resistance in microbes is a natural process, the overuse of antibiotics is known to increase the rate of resistance evolution. Under antibiotic treatment, susceptible bacteria inevitably die, while resistant microorganisms proliferate under reduced competition. Therefore, the out-of-control use of antibiotics eliminates drug-susceptible species that would naturally limit the expansion of resistant species. In addition, the ability of many microbial species to grow as a biofilm has further complicated the treatment of infections with conventional antibiotics. A number of corrective measures are currently being explored to reverse or slow antibiotic resistance evolution, Among which one of the most promising solutions is the development of polymer-based antimicrobial compounds. In this Special Issue, different polymer systems able to prevent or treat biofilm formation, including cationic polymers, antibacterial peptide-mimetic polymers, polymers or composites able to load and release bioactive molecules, and antifouling polymers able to repel microbes by physical or chemical mechanisms are reported. Their applications in the design and fabrication of medical devices, in food packaging, and as drug carriers is investigated.

single toxicant before it, yet one that has now been brought under effective control-at least in estuaries and the nearshore environment. The problem with TBT and its cause was first recognized in France, then in the United Kingdom and the United States of America; and in these and other countries legislation is now in place (see Abel, Chapter 2; Champ and Wade, Chapter 3), but in many countries the hazard is only now being identified. This volume has the important function of making available to all a summary of the results of work on TBT and the main conclusions. It will help to minimize the duplication of research and speed the introduction of legislation around the world to control organotin pollution. It is the more valuable because research on TBT has often been published in less accessible journals and symposium proceedings. This volume brings together accounts of these findings by the major contributors to the TBT story, providing the most comprehensive account to date. The TBT problem has proved to be instructive in a number of different ways beyond the bounds of the specific issue (Stebbing, 1985). Most important is that TBT can be seen as a challenge to monitoring systems for nearshore waters, by which it can be judged how effective monitoring has been in fulfilling its purpose, and what improvements should be made. Most instructive was the time it took to bring TBT under control.
