Factors Influencing Zinc Cementation of Cadmium
The research reported here examines an innovative procedure for removal of cadmium from wastewaters. This process is the cementation of cadmium by zinc metal. Cementation is highly attractive...

Simplified Heavy Metals Model for Rivers

Trenching of Digested Sludge
Effects of trenching digested sludge were evaluated for 4 yr. Digested sludge buried in trenches that were 2 ft (0.6m) wide by 2 ft (0.6m) deep and 2 ft (0.6m) apart was sampled along...

Zinc from Automobile Tires in Urban Runoff
Zinc and lead are among the most prevalent toxic heavy metals found in urban runoff. Heavy metals in urban runoff may be derived from sources other than automobile traffic. The intent...

Environmental Transport Model of Heavy Metals
A general model TOHM was developed to predict the transport of heavy metals originating from the stack emissions of a coal-fired electric generating facility into a final environmental...

Hazardous Wastes Input into Class I Landfills
This study documents 17 metal species discharged to Class I landfill sites. These sites receive a combined estimated daily volume of 2.3 x 106 1/day...

Physical Properties of Pb-Zn Mine-Process Wastes

Trace Metals in Open Water Disposal of Dredged Material
Upon addition of sediment/seawater mixture to the seawater column, most trace metals were found to display a pattern of immediate release. These released metals were subsequently removed....

Zinc Paint Can Save $500,000 On Your Powerplant
Zinc-rich paints have been used for 20 years now. However, those responsible for protecting powerplants and many other utility and industrial structures are still using the alkyd paints....

Bolted Joints under Sustained Loading
A study of bolted structural joints under sustained loads (1,000 hours) was made to determine long-term joint slip. Joints representative of antenna structural joints were used. These...

Aluminum Corrosion at Urban and Industrial Locations
Seven-year exposures of several aluminum alloys, mild steel and zinc demonstrate the excellent corrosion resistance of aluminum in urban and industrial environments. Panels of aluminum-manganese...

Trace Metal Accumulation by Estuarine Mollusks
In view of the relative paucity of information on trace metal distribution in marine animals, a series of studies were Initiated in order to investigate the mechanics of concentration...

Surface Treatment of High-Strength Bolted Joints
The effect of galvanizing on the ASTM A325 and A490 high-strength bolts and the performance of bolted joints under static loads in which the faying surfaces were galvanized, cold zinc...
