Environmental Contaminants


Book Description

The human footprint on the global environment now touches every corner of the world. This book explores the myriad ways that environmental archives can be used to study the distribution and long-term trajectories of chemical contaminants. The volume first focuses on reviews that examine the integrity of the historic record, including factors related to hydrology, post-depositional diffusion, and mixing processes. This is followed by a series of chapters dealing with the diverse archives and methodologies available for long-term studies of environmental pollution, such as the use of sediments, ice cores, sclerochronology, and museum specimens.

This is the second volume in the series and deals mainly with physical and geochemical analytical techniques.




Scientific Integrity and Ethics in the Geosciences


Book Description

Science is built on trust. The assumption is that scientists will conduct their work with integrity, honesty, and a strict adherence to scientific protocols. Written by geoscientists for geoscientists, Scientific Integrity and Ethics in the Geosciences acquaints readers with the fundamental principles of scientific ethics and shows how they apply to everyday work in the classroom, laboratory, and field. Resources are provided throughout to help discuss and implement principles of scientific integrity and ethics. Volume highlights include: Examples of international and national codes and policies Exploration of the role of professional societies in scientific integrity and ethics References to scientific integrity and ethics in publications and research data Discussion of science integrity, ethics, and geoethics in education Extensive coverage of data applications Scientific Integrity and Ethics in the Geosciences is a valuable resource for students, faculty, instructors, and scientists in the geosciences and beyond. It is also useful for geoscientists working in industry, government, and policymaking.
