One of the predicted consequences of the depletion of stratospheric ozone is an increase in the amount of ultraviolet light reaching the surface of the earth, in particular UV-B (320-280nm). Although the real effects are as yet unknown, this change in radiation could have profound consequences for plant growth and productivity. The need for information concerning the relationship between plants and UV-B is therefore pressing. This volume brings together authoritative contributions from leading experts in UV-B/plant studies and is unique in considering interactions at various scales, ranging from the level of the cell through to the level of the community. Information concerning ozone depletion and physical aspects of UV-B radiation complements the biological information to provide a thorough and comprehensive review of the present status of knowledge.

"Regular use of sunscreens has been shown to reduce the risk of sunburn and skin cancer, and slow photoaging of skin. Sunscreens can rinse off into water where people are swimming or wading, and can also enter bodies of water through wastewater such as from bathing or showering. As a result, the ultraviolet (UV) filters - the active ingredients in sunscreens that reduce the amount of UV radiation on skin - have been detected in the water, sediment, and animal tissues in aquatic environments. Because the impact of these filters on aquatic ecosystems is not fully understood, assessment is needed to better understand their environmental impacts. This report calls on the U.S. Environmental Protection Agency to conduct an ecological risk assessment of UV filters to characterize the possible risks to aquatic ecosystems and the species that live in them. EPA should focus on environments more likely to be exposed such as those with heavy recreational use, or where wastewater and urban runoff enter the water. The risk assessment should cover a broad range of species and biological effects and could consider potential interacting effects among UV filters and with other environmental stresses such as climate change. In addition, the report describes the role of sunscreens in preventing skin cancer and what is known about how human health could be affected by potential changes in usage. While the need for a risk assessment is urgent, research is needed to advance understanding of both risks to the environment from UV filters and impacts to human health from changing sunscreen availability and usage"--

This book is a rich source of information on skin disorders due to toxicants in the environment. State of the art knowledge is summarized concerning the molecular basis of skin damage caused by well-appreciated environmental noxae. The book also provides a uniquely comprehensive overview of the detrimental dermatological effects of exposure to air pollution and global climate change. A special focus is contact allergy, which, beyond representing a major problem in dermatotoxicology, serves as a prime example for the development of toxicological approaches to risk assessment. A further chapter is devoted to contact urticaria, a condition that can progress to life-threatening anaphylactic reactions. The novel information offered in this book will enable the reader to go beyond the traditional thinking of dermatotoxicology and achieve a modern appreciation of the highly complex interplay between skin and environment.
