Meeting The Scientific Needs Of Ecological Risk Assessment In A Regulatory Context, Steven P. Bradbury, Tom C. Feitel, Cornelis J. Van Leeuwen Dec 2004

Meeting The Scientific Needs Of Ecological Risk Assessment In A Regulatory Context, Steven P. Bradbury, Tom C. Feitel, Cornelis J. Van Leeuwen

Steven P. Bradbury

During the past decade, the field of ecological risk assessment has progressed considerably. Advances have come from such international bodies as the Organisation for Economic Co-operation and Development (OECD), the World Health Organisation (WHO), the European and Mediterranean Plant Protection Organisation (EPPO), and the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) (1–8). Risk assessments have played a critical role in the development of various regulations within the European Commission (EC) as well as in other parts of the world, including the United States, Canada, and Japan (9–17). But scientists and regulators are faced with three significant challenges: streamlining …


A Correlation Study Of Wind Speeds At Norski Runs And Valders Hall Of Science, Paul D. B. Skrade, Dale M. Nimrod Mar 2004

A Correlation Study Of Wind Speeds At Norski Runs And Valders Hall Of Science, Paul D. B. Skrade, Dale M. Nimrod

Paul D. B. Skrade

1976 and 1977 wind speeds were recorded from the roof of Valders Hall of Science, Luther College, Decorah, Iowa in a correlation study of wind-sun energy. Summer 2004 wind speeds and directions were recorded with the hopes of correlating the speeds at Valders Hall of Science and at Norski Runs, Chattahoochie County Park, Decorah, Iowa, a site for a potential Luther College wind farm. Motivation behind the study was to determine if topology of Upper Iowa River Valley affected wind speeds.
