The First Symposium on Use of Plants for Toxicity Assessment was held in Atlanta, Georgia, on April 19-20, 1989. This publication contains 29 refereed papers divided into six groups: Regulatory Perspectives, Comparative Toxicology, Plants and Xenobiotic Uptake, Plants and Air Pollution, General Phytotoxicology, and New Approaches. The 2nd Symposium on Use of Plants for Toxicity Assessment was held in San Francisco, California, on April 23-24, 1990. This publication contains 35 refereed papers divided into six groups: Regulatory Perspectives, Applications of Plant Bioassays/Photosynthesis, Xenobiotic Uptake by Plants, General Phytotoxicology, Biochemical and Genetic Applications, and New Approaches.

Toxicological Survey of African Medicinal Plants provides a detailed overview of toxicological studies relating to traditionally used medicinal plants in Africa, with special emphasis on the methodologies and tools used for data collection and interpretation. The book considers the physical parameters of these plants and their effect upon various areas of the body and human health, including chapters dedicated to genotoxicity, hepatotoxicity, nephrotoxicity, cardiotoxicity, neurotoxicity, and specific organs and systems.Following this discussion of the effects of medicinal plants is a critical review of the guidelines and methods in use for toxicological research as well as the state of toxicology studies in Africa. With up-to-date research provided by a team of experts, Toxicological Survey of African Medicinal Plants is an invaluable resource for researchers and students involved in pharmacology, toxicology, phytochemistry, medicine, pharmacognosy, and pharmaceutical biology. - Offers a critical review of the methods used in toxicological survey of medicinal plants - Provides up-to-date toxicological data on African medicinal plants and families - Serves as a resource tool for students and scientists in the various areas of toxicology

Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.

Die Bioremediation ist ein Verfahren, bei dem biologische Verfahren eingesetzt werden, um industrielle Schadstoffe in verschiedenen Ökosystemen wieder in den natürlichen Stoffkreislauf zurückzuführen. Ob die Bioremediation erfolgreich ist oder nicht, hängt entscheidend vom Verständnis des biotechnologischen Prozesses und von den Stärken und Schwächen der eingesetzten ökotoxikologischen Verfahren ab. "Environmental Analysis of Contaminated Sites" diskutiert umweltanalytische Verfahren und Methoden zur Bewertung der erfolgreichen Sanierung kontaminierter Bodensysteme. Ein nützlicher Leitfaden, der diese komplexe Thematik umfassend behandelt, indem er Ökotoxizitätstests für den Bodenschutz, die Bioremediation und die Risikobewertung der Umweltgefährdung miteinander verbindet. Darüber hinaus beschreibt er das Zusammenwirken von ökotoxikologischer Labor- und Felduntersuchung, Biotechnologie Consultants und verschiedenen internationalen Umweltkontrollbehörden und erklärt, wie sie gemeinsam an einer erfolgreichen Auswertung sanierter Umweltsysteme arbeiten. Mit zahlreichen Fallstudien zu erfolgreichen und gescheiterten Projekten.

A dozen papers from a symposium in Phoenix, Arizona, January 1995 provide researchers and practitioners with the current modifications of the EPA's basic methodology for assessing the health risk of releasing chemicals into the environment. They cover determining background concentrations, collectin

Environmental and Ecological Chemistry is a component of Encyclopedia of Chemical Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Environmental and Ecological Chemistry prsents the essential aspects such as: Fundamental Environmental Chemistry; Atmospheric Chemistry; Soil Chemistry; Aquatic Chemistry; Ecological Chemistry; Chemistry of Organic Pollutants Including Agrochemicals. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
