The Tropospheric Chemistry of Ozone in the Polar Regions
Author: H. Niki
Publisher: Springer Science & Business Media
ISBN: 3642782116
Category : Science
Languages : en
Pages : 431
Book Description
The Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.

Plastics and the Environment
Author: Anthony L. Andrady
Publisher: John Wiley & Sons
ISBN: 9780471095200
Category : Science
Languages : en
Pages : 792
Book Description
Plastics offer a variety of environmental benefits. However, their production, applications, and disposal present many environmental concerns. Plastics and the Environment provides state-of-the-art technical and research information on the complex relationship between the plastic and polymer industry and the environment, focusing on the sustainability, environmental impact, and cost—benefit tradeoffs associated with different technologies. Bringing together the field’s leading researchers, Anthony Andrady’s innovative collection not only covers how plastics affect the environment, but also how environmental factors affect plastics. The relative benefits of recycling, resource recovery, and energy recovery are also discussed in detail. The first of the book’s four sections represents a basic introduction to the key subject matter of plastics and the environment; the second explores several pertinent applications of plastics with environmental implications–packaging, paints and coatings, textiles, and agricultural film use. The third section discusses the behavior of plastics in some of the environments in which they are typically used, such as the outdoors, in biotic environments, or in fires. The final section consists of chapters on recycling and thermal treatment of plastics waste. Chapters include: Commodity Polymers Plastics in Transportation Biodegradation of Common Polymers Thermal Treatment of Polymer Waste Incineration of Plastics The contributors also focus on the effectiveness of recent technologies in mitigating environmental impacts, particularly those for managing plastics in the solid waste stream. Plastic and design engineers, polymer chemists, material scientists, and ecologists will find Plastics and the Environment to be a vital resource to this critical industry.

Marine Litter

ISBN:
Category : Business & Economics
Languages : en
Pages : 244
Book Description
Marine litter is an ecological, economic, health and aesthetic problem. it is a complex and multi-dimensional challenge with significant implications For The marine and coastal environment, and human activities all over the world. The persistence of marine litter is the result of a lack of coordinated global and regional strategies, and deficiencies in the implementation and enforcement of existing programmes, regulations and standards at all levels - international, regional and national. The UNEP Global Initiative on Marine Litter provides a platform For The management of marine litter through the establishment of partnerships, cooperative arrangements and coordination of joint activities. it has succeeded in organizing and implementing regional activities on marine litter around the world. In addition to activities in 12 Regional Seas, UNEP commissioned preparation of several documents on specific topics, including UNEP/IOC Guidelines for monitoring of marine litter; Abandoned and lost fishing gear; and Marine litter and market-based instruments. This report provides an overview of the status of marine litter in UNEP's assisted Regional Seas, and highlights the amounts, main sources, impacts, and economics of marine litter, and discusses legislation, policies, compliance and enforcement mechanisms; institutional frameworks and stakeholder involvement; education and outreach strategies; monitoring programmes and research; mitigation activities among other aspects. it concludes that there is an urgent need to approach the issue of marine litter through better enforcement of laws and regulations, expanded outreach and educational campaigns And The employment of strong economic instruments and incentives. it proposes some general recommendations, based on the materials presented in the document, and specific recommendations for fourteen different issues regarding marine litter.

Contaminated Sediments in Ports and Waterways
Author: Division on Engineering and Physical Sciences
Publisher: National Academies Press
ISBN: 0309054931
Category : Nature
Languages : en
Pages : 318
Book Description
Contaminated marine sediments threaten ecosystems, marine resources, and human health. They can have major economic impacts when controversies over risks and costs of sediment management interfere with needs to dredge major ports. Contaminated Sediments in Ports and Waterways examines management and technology issues and provides guidance that will help officials make timely decisions and use technologies effectively. The book includes recommendations with a view toward improving decision making, developing cost-effective technologies, and promoting the successful completion of cleanup projects. The volume assesses the state of practice and research and development status of both short-term and longer-term remediation methods. The committee provides a conceptual overview for risk-based contaminated sediment management that can be used to develop plans that address complex technological, political, and legal issues and the interests of various stakeholders. The book emphasizes the need for proper assessment of conditions at sediment sites and adequate control of contamination sources.
