Chemical Fate, Transport, and Process Analysis Risk Assessment Overview Exposure Assessment Chemcial Fate, Transport, Process Analysis Statistical Analysis Risk Communication Chemical Fate, Transport, and Process Analysis Aeolus is a leader in the evaluation and prediction of chemical fate and transport and chemical process analysis having pioneered many of the procedures that remain in use today.  When needed, we have also continued to develop innovative procedures for modeling and assessing novel fate and transport pathways for a variety of clients. By matching the manner in which chemical fate and transport are evaluated to planning for the supporting investigations, Aeolus helps to focus the supporting data collection effort to control costs and eliminate superfluous or redundant effort.  Further, by linking the manner in which fate and transport pathways are evaluated to the specific, critical decisions defined for a project, the collection and evaluation of data can also be focused to minimize decision errors.    To view and download: Considerations for statistical design of an effective study Overview of the DQO process The link between data quality and decision errors Citations for statistics papers To save Adobe Acrobat (.pdf) files, once loaded, click the indicated icon in acrobat.
