Ecotoxicology of Wild Mammals Ecotoxicology of Wild Mammals
An international group of 32 scientists has critically reviewed the scientific literature on exposure and effects of environmental contaminants in wild mammals. The underlying theme of this text is encompassed by the following four questions: What exactly do we know about environmental contaminants in mammals? What are the commonalities and differences between mammal orders/species in...
Nitrogen Nitrogen
US ammonia production in 2000 declined by about 7% from 1999. The largest decline occurred in the second half of the year. High natural gas prices caused many plants to close or curtail production near the end of the year. By year-end, about one-third of the US ammonia production capacity was shut down.

Fluorspar Fluorspar
A general overview of the fluorspar industry is provided. The U.S. had no reported mine production in 2000. Imports, sales from the U.S. National Defense Stockpile, and small amounts of synthetic fluorspar met domestic fluorspar needs. According to the U.S. Geographical Survey, 509 kt of fluorspar was consumed domestically.

Kaolin Kaolin
Part of the 2000 annual review of the industrial minerals sector. A general overview of the kaolin industry is provided. In 2000, production of kaolin was estimated to be 8.87 Mt, which is less than the amount produced in 1999. Domestic sales of kaolin decreased in 2000, with sales of kaolin for paper filler applications continuing to drop.

Book review: Birds of Delaware Book review: Birds of Delaware
Located along Delaware Bay and the Atlantic coast, the state of Delaware’s significance for bird conservation has been well established for decades. The extensive tidal habitats and marshes bordering Delaware Bay host shorebird and waterbird populations of hemispheric importance, and protecting these populations has become an urgent conservation priority in recent years. Other habitats...

Evaluation of borehole geophysical logs and hydraulic tests, phase III, at AIW Frank/Mid-County Mustang Superfund Site, Chester County, Pennsylvania Evaluation of borehole geophysical logs and hydraulic tests, phase III, at AIW Frank/Mid-County Mustang Superfund Site, Chester County, Pennsylvania
Borehole geophysical logs, heatpulse-flowmeter measurements, and aquifer-isolation tests were used to characterize the ground-water-flow system at the AIW Frank/Mid-County Mustang Superfund Site. The site is underlain by fractured carbonate rocks. Caliper, natural-gamma, single-point-resistance, fluid-resistivity, and fluid-temperature logs were run in six wells, and an acoustic borehole
