: Selective review and synthesis of the technical literature on copper and copper salts in the environment and their effects primarily on fishes, birds, mammals, terrestrial and aquatic invertebrates, and other natural resources. The subtopics include copper sources and uses; chemical and biochemical properties; concentrations of copper in field collections of abiotic materials and living organisms; effects of copper deficiency; lethal and sublethal effects on terrestrial plants and invertebrates, aquzatic organisms, birds, and mammals, including effects on survival, growth, reproduction, behavior, metabolism, carcinogenicity, mutagenicity, and teratogenicity; proposed criteria for the protection of human health and sensitive natural resources; and recommendations for additional research.

Diazinon Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review

Induction of hepatic mixed function oxidases by the insecticide, mirex.

The effects of 001, 01, 10 and 100 ppb mirex on the development of blue crabs,Callinectes sapidus, from hatching to first crab stage are described None of the concentrations of mirex showed any appreciable effect on the larvae during the first five days Thereafter 001 ppb and 01 ppb mirex were found to be sublethal These concentrations had no effect on the duration of development from hatching to megalopa or from hatching to first crab stage Concentrations of 10 ppb and 100 ppb mirex proved to be acute No one stage of development was particularly sensitive to 001 ppb mirex, but in the other three concentrations some stages were more sensitive (statistically) than others The results of residue analyses are given for larvae reared in four concentrations of mirex at different periods of development Residues of mirex in developmental stages increased with concentration, but biological magnification was greatest in larvae reared in the lowest concentration of mirex and lowest in larvae reared in the highest concentration

Effects of mirex on the larval development of blue crab

A perchlorinated, cage-structured hydrocarbon, C(10)C(l2), also known as mirex or Dechlorane, has been identified in fish samples from the Bay of Quinte, Lake Ontario, Canada. The compound coelutes with polychlorinated biphenyls (PCB's) in residue cleanup procedures and under standard gas chromatographic conditions. Mirex has never been registered for use as an insecticide in Canada, nor does it appear to be in use in any area of the United States discharging water into Lake Ontario or its tributaries. It seems likely, therefore, that this compound is another widespread environmental contaminant of extremely high geochemical stability and as yet only superficially investigated biological activities. Under standard gas chromatographic conditions its peak is superimposed on that of the PCB's, and, as a result, the presence of mirex may have been unrecognized and it may therefore have been misinterpreted as a PCB isomer.
