This volume is a collection of papers resulting from a symposium held at the 2002 Annual Meeting of the Association of Environmental and Engineering Geologists in Reno, Nevada. The majority of the chapters present hydro-geochemical studies of select sites, but with the variety of localities and approaches taken, this book will more widely appeal to land and resource managers, geologists, and engineers working with abandoned mines or modern site remediation efforts.

There is widespread public concern about hazardous chemicals that are contained in air, soil, water and food. Policy has therefore adopted a series of laws and regulations concerning emissions into and concentration levels in different media including food. As policy makers do not only have to consider the protection of the environment but also need to ensure a well-functioning economy at the same time, these limit or target values need to be set in a balanced way. The main problem, however, is to compare the costs for achieving these targets with the benefits to society by having a smaller exposure to hazardous substances (cost-benefit analysis). This book sets out to improve the reliability of cost-benefit analyses particularly of hazardous substances present in air, water, soil and food. It suggests that the human health risk assessment of chemicals is performed in a bottom-up analysis, i.e., following a spatially resolved multimedia modelling approach. In order to support cost-benefit analyses, the approach is accompanied by monetary valuation of human health impacts, yielding so-called external costs. Results for selected priority metals show that these external costs are small compared to those by the classical air pollutants and involve rather long time horizons touching on the aspect of intergenerational equity within sustainable development. When including further hazardous substances, the total external costs attributable to contaminants are expected to be more substantial.

The aim of the project is to create knowledge on how plastics recycling can increase without increasing the risk of emitting hazardous substances to the environment.The first general conclusion is that to be able to increase recycling there are measures needed at different levels. The following areas are of interest: • Legislation: new legislation is not necessary, but harmonisation and clear guidance to the existing one is. • Market: to create a market safety on content is needed. • If substances added are less hazardous the recycled raw material would be “more safe” to use. • There should be higher attention put on the knowledge of the recyclers. • Traceability and content: Further work on labelling reaching the recycle part of the value chain needs to be developed. It is also needed to develop a systematic approach towards risk assessments linked to recycling.

Correlating chemical structure with toxicity to humans and the environment, and the chemical structure of compounds to their hazardous properties, this book allows users to assess the toxicity of a substance even when no experimental data exists. Thus, it bridges the gap between hazardous materials and chemistry. Extensively updated and expanded.
