Book Description

Report, the editors replaced the term "speciation" wherever it occurred by "identification and quantification," or "description of abundance," or "reactivity," or "transformation" of a chemical species, according to whichever one of the four meanings the author had evidently meant to convey. In line with the Dahlem Workshop Model, this Report comprises the background papers written in advance of the meeting on the current status of problems in environmental research and on advanced analytical tech niques for the identification and quantification of chemical species, as well as the group reports summarizing the results of the discussions held during the meeting. Each group report was prepared during the meeting by one "rapporteur" with the help of members of that group and finalized by the rapporteur (listed as the first author of the group report) after the meeting, taking into account both verbal comments made during the presentation of the reports in the plenary session at the end of the workshop and written comments received afterwards.

Book Description

Until the publication of this new book there had been a lack of well-founded guidelines for evaluating concentrations of lead in soil and its relationship to human health. Thus, much confusion has existed among regulatory agencies, industries, public health officials, and the medical community about the evaluation and remedying of lead-contaminated soils. Lead in Soil: Recommended Guidelines represents the combined efforts of a multi-disciplinary international task force from the Society for Environmental Geochemistry and Health (SEGH) whose members are experts in the fields of lead pollution and toxicology. It provides an international consensus concerning environmental lead and blood lead-especially in children. The task force evaluated the evidence and made recommendations for guidelines to appraise lead concentration. It also studied the influence of soil and other sources of lead on blood lead concentrations. A model was prepared that allows the user to select appropriate target levels of blood lead while allowing for a variety of environmental situations or regulatory criteria.
