PAHs: An Ecotoxicological Perspective Summary
| "PAHs (polycyclic aromatic hydrocarbons) are in the spotlight: they are a unique class of persistent organic pollutants constituted by hundreds of individual substances. Regulatory attention and research efforts are increasing. The timely publication of this book updates key aspects of our knowledge. The book starts with ecotoxicological aspects of PAHs, considering their initial formation, then their fate and effects in most environmental compartments. The second part considers the general characteristics of these compounds, beginning with sources and transport in the environment. PAHs are degraded by sunlight and by microorganisms. Metabolism in higher biota may be less important for the overall fate of PAHs, but it is crucial in terms of the formation of carcinogenic metabolites. In the third part, some fundamental aspects of partitioning and bioavailability are discussed, then PAH uptake and effects are considered for invertebrates, fish, birds, mammals and amphibia in freshwater, marine and terrestrial environments. PAH impairment of plant growth and development is also covered. Alteration through photo-activation, often overlooked, is included here. The chapter on biomarkers focuses on aquatic organisms. The final part addresses the issues involved with integrating our knowledge of PAHs for a specific purpose. It ranges from various approaches to developing sediment quality guidelines to a practical example of managing risk from PAHs, highlighting the problems and solutions in a case study. This book will be of interest to industrial and academic research scientists in ecotoxicology, environmental studies/management, toxicology and chemistry; environmental agencies and consultants, NGOs involved in risk assessment." |
