Bioavailability of sludge-associated chemicals to terrestrial and aquatic organisms.Identification of pollutants released via the water, air and to soil following sewage sludge (biosolids) applications and associated effects.
Organic contaminants in organisms, including fishes of Virginia waters. Ph.D., College of William and Mary, 1983. The beryl is green to blue-green and occurs in crystals 0.2 to 2 inches long and 0.1 to 2 inches in diameter, but most of the crystals are very small.My primary research interests center on the identification of anthropogenic organic pollutants and the elucidation of their sources, fate, bioavailability and effects on ecosystems. Also the fate and consequences of microplastics and associated chemicals, e.g. Most of the beryl occurs in the core, either with small anhedral crystals of perthite scattered in a matrix of coarse quartz, plagioclase and accessory tourmaline, or with fine-grained quartz, plagioclase, and accessory tourmaline. The core consists of medium- to coarse-grained quartz and perthite with subordinate amounts of plagioclase, muscovite, and accessory beryl, tourmaline, columbite-tantalite and monazite. The border zone is ½ to 1 inch thick and is composed of fine-grained quartz, plagioclase and tourmaline. The dike, a disseminated type of beryl deposit, consists chiefly of quartz and perthite. The pegmatite does not seem to extend across the contact. The contact between the Monson gneiss and the Bolton schist lies 60 feet west of the westernmost exposure of the pegmatite. and dips westward at moderate to steep angles. The dike is sharply discordant to the enclosing granite-gneiss (Monson gneiss), whose foliation strikes N. 
The pegmatite is a tabular body at least 180 feet long and 6 to 8 feet thick. Both pits are free of water and probably contain little backfill. The lower opencut is 38 feet long, 10 feet wide, and 5 to 18 feet deep.
The upper opencut is 25 feet long, 9 feet wide, and 1 to 10 feet deep. William Wilkes, superintendent, about 70 tons of no. In 1932 two small cuts were opened on the Walker property by the Eureka Flint & Spar Co., Portland, and were worked for 3 or 4 months for feldspar. It may extend eastward beneath overburden to land owned by Clifford Hale, R. The pegmatite.crops out on land owned jointly by Charles F.
