Los ensayos de toxicidad son pruebas diseñadas para evaluar la potencia relativa de un agente o una sustancia contaminante sobre una o más especies de organismos de los sistemas biológicos acuáticos y terrestres, al tiempo que permiten caracterizar la relación concentración-respuesta entre el agente contaminante y el organismo sometido a prueba. La toxicidad de una sustancia es la propiedad que tiene de causar daños a la salud humana o la muerte de un organismo vivo, mediante la comparación de efecto del agente con el de una solución patrón o estándar.Los resultados de las pruebas de toxicidad en sistemas acuáticos constituyen un criterio importante para determinar el efecto y el riesgo de la descarga de sustancias contaminantes sobre los ecosistemas acuáticos, así como para establecer valores límites permisibles para el control de sustancias tóxicas que son incorporadas a los ecosistemas acuáticos.Con la euge de la ecotoxicología ciencia que predice de los agentes potencialmente tóxicos en los ecosistemas naturales (Hoffman, 1995) se ha reforzado la idea de realizar monitoreos y pruebas de toxicidad para la detección, predicción y control de los efectos de diferentes tipos de sustancias sobre los ecosistemas, en particular, el acuático.

Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.

Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

This volume evaluates the carcinogenic risk to humans posed by infection with human papillomaviruses (HPVs). To date, more than 70 HPV types have been identified, of which over 15 have been reported in cervical cancer biopsies. Worldwide, cervical cancer is the second most common cancer in women. This book also considers the possible involvement of HPV infection in cancers at other sites of the human body.

A comprehensive, extensive textual analysis of the principles of solvent selection and use, the handbook is intended to help formulators select ideal solvents, safety coordinators to protect workers, and legislators and inspectors to define and implement technically correct public safeguards for use, handling, and disposal.
