The Federal Food Safety System: A Primer

Description: The combined efforts of the food industry and the regulatory agencies often are credited with making the U.S. food supply among the safest in the world. Nonetheless, many food-related health issues persist. At issue is whether the current U.S. regulatory system has the resources and structural organization to protect consumers from these dangers. Also at issue is whether the federal food safety laws themselves, first enacted in the early 1900s, have kept pace with the significant changes that h… more

Mathematical simulation of transport of sediment and kepone in the James River estuary

Description: The mathematical simulation of sediment and Kepone (a highly chlorinated pesticide) transport in the James River estuary was conducted by applying the sediment and contaminant transport model, FETRA, to an 85-km river reach between Bailey and Burwell Bays. The FETRA code is an unsteady, two-dimensional, finite model, utilizing the Galerkin weighted residual method. The model consists of three submodels coupled together to take into account sediment-contaminant interaction. the submodels are: (1… more

Evaluation of effects of phenol recovery on biooxidation and tertiary treatment of SRC-I wastewater. Final technical report

Description: Addition of phenol recovery to the wastewater treatment scheme in the Baseline Design for the SRC-I Demonstration Plant was evaluated as a major post-Baseline effort. Phenol recovery affects many downstream processes, but this study was designed to assess primarily its effects on biooxidation and subsequent tertiary treatment. Two parallel treatment schemes were set up, one to treat dephenolated wastewaters and the other for processed nondephenolated wastewaters, a simulation of the Baseline De… more

Current deposition of kepone residuals in the Hopewell, Virginia area

Description: The exact amount of kepone released into the environment since production begin in Hopewell, Virginia, in 1966 is not known. It has been estimated, however, that roughly one hundred thousand pounds of the chemical were released during the period 1966 to 1975 from the Allied Chemical Corporation semi-works plant and the Life Sciences Products Company. This total resulted from the continuous release of kepone-saturated wastewaters, particulate emissions, and bulk disposal of waste batches of the … more

Methods and applications of HPLC-AMS (WBio 5)

Description: Pharmacokinetics of physiologic doses of nutrients, pesticides, and herbicides can easily be traced in humans using a {sup 14}C-labelled compound. Basic kinetics can be monitored in blood or urine by measuring the elevation in the {sup 14}C content above the control predose tissue and converting to equivalents of the parent compound. High Performance Liquid Chromatography (HPLC) is an excellent method for the chemical separation of complex mixtures whose profiles afford estimation of biochemica… more
