From Kepone to Exxon Valdez Oil and Beyond: An Overview of Natural Resource Damage Assessment

In July 1975, officials from the Virginia State Department of Health learned that employees of the Life Science Product Company ( Life Science ), in Hopewell, Virginia, had been poisoned by a toxic chemical known as Kepone. Life Science had produced Kepone under contract for Allied Chemical Corporation ( Allied Chemical ), the original developer and manufacturer. Shortly thereafter, state officials discovered that both Life Science and Allied Chemical had unlawfully discharged Kepone into freshwater tributaries of the James River. In addition to poisoning their own employees, Life Science and Allied Chemical had also contaminated Virginia\u27s atmosphere, soil, and wa- terways with Kepone

Uptake of Kepone by oysters exposed to contaminated sediments mixed with lignite

Preliminary studies conducted by personnel of the Allied Chemical Corporation at Morristown, N. J. suggested that coa] would be used to adsorb Kepone from an aquatic substrate. .The possibility of using coal to bind Kepone contaminating the natural environment indicated further preliminary exploration of the matter. The Virginia Institute of Marine Science undertook a laboratory study with oysters under contract with the Allied Chemical Corp. to explore that possibility. Lignite was mixd on a 1:10 dry-weight ratio with sediments contaminated with Kepone

Foliar Fertilization of Soybeans - 1977

Field investigations on the effect of foliar fertilization were continued on soybeans during 1977. Results from our 1976 studies have previously been published. In 1976 we tested a material produced by TVA. We used the same TVA-material in 1977 and in addition, included a commercially available product (Foliantm, manufactured by Allied Chemical Corporation)

Allied Chemical, the Kepone Incident, and the Settlements: Twenty Years Later

Twenty years ago this July the happenings at a small chemical plant in Hopewell, Virginia ushered in what has since become an incident of national impact and importance. Through the prosecution of criminal cases, the filing of civil personal injury suits and the closing of the James River to fishing, the release of the chemical from the Kepone manufacturing process gained national attention

Method of neutralizing the corrosive surface of amine-cured epoxy resins

The corrosive alkaline surface layer of an epoxy resin product formed by the curing of the epoxy with an aliphatic amine is eliminated by first applying a non-solvent to remove most or all of the free unreacted amine and then applying a layer of a chemical reagent to neutralize the unused amine or amine functional groups by forming a substituted urea. The surface then may be rinsed with acetone and then with alcohol. The non-solvent may be an alcohol. The neutralizing chemical reagent is a mono-isocyanate or a mono-isothiocyanate. Preferred is an aromatic mono-isocyanate such as phenyl isocyanate, nitrophenyl isocyanate and naplthyl isocyanate

Study to establish cost projections for production of Redox chemicals

A cost study of four proposed manufacturing processes for redox chemicals for the NASA REDOX Energy Storage System yielded favorable selling prices in the range $0.99 to$1.91/kg of chromic chloride, anhydrous basis, including ferrous chloride. The prices corresponded to specific energy storage costs from under $9 to$17/kWh. A refined and expanded cost analysis of the most favored process yielded a price estimate corresponding to a storage cost of $11/kWh. The findings supported the potential economic viability of the NASA REDOX system

Barium release system

A chemical system is described for releasing a good yield of free barium neutral atoms and barium ions in the upper atmosphere and interplanetary space for the study of the geophysical properties of the medium. The barium is released in the vapor phase so that it can be ionized by solar radiation and also be excited to emit resonance radiation in the visible range. The ionized luminous cloud of barium becomes a visible indication of magnetic and electrical characteristics in space and allows determination of these properties over relatively large areas at a given time
