Effects of copper ore on the ecology of a lagoon.
MetadataShow full item record
A large-scale experiment was conducted in a lagoon, off the Galveston Ship Channel in the Gulf of Mexico, to determine the feasibility of using copper ore as a control for destructive plankton blooms. A chemical and biological study was made of the lagoon for a period of 9 months previous to the addition of 60 tons of copper ore. Comparison with a similar study made after the addition of the ore revealed that the ore did not have the desired qualities of control; therefore its use for control was not recommended.
