- **Background:**
**This online       document--PDF format (and compact disc) contains the 35 reports in the Contaminant       Hazard Reviews (CHR) that were published originally between 1985 and 1999       in the U.S. Department of the Interior Biological Report series. The CD       was produced because printed supplies of these reviews--a total of 105,000--became       exhausted and demand remained high. Each review was prepared at the request       of environmental specialists of the U.S. Fish and Wildlife Service and each       contained specific information on selected metals and metalloids (silver,       arsenic, boron, cadmium, chromium, copper, mercury, lead, molybdenum, nickel,       tin, selenium, zinc), organics (polychlorinated biphenyls, polycyclic aromatic       hydrocarbons, dioxins, acrolein, diazinon, atrazine, fenvalerate, famphur,       chlordane, chlorpyrifos, cyanide, diflubenzuron, mirex, carbofuran, toxaphene,       compound 1080, paraquat, pentachlorophenol), ionizing radiation, and a cumulative       index to chemicals and species.  Each report reviews and synthesizes       the technical literature on a single contaminant and its effects on terrestrial       plants and invertebrates, aquatic plants and animals, avian and mammalian       wildlife, and other natural resources. The subtopics include contaminant       sources and uses; physical, chemical, and metabolic properties; concentrations       in field collections of abiotic materials and living organisms; deficiency       effects, where appropriate; lethal and sublethal effects including effects       on survival, growth, reproduction, metabolism, mutagenicity, teratogenicity,       and carcinogenicity; proposed criteria for the protection of human health       and sensitive natural resources; and recommendations for additional research.       All reports were authored by Dr. Ronald Eisler       of the USGS Patuxent Wildlife Research Center located in Laurel, Maryland.        Patuxent staff who participated in producing this CD were Ronald Eisler,       Robert E. Munro, Lois M. Loges, Kinard Boone, Mary M. Paul, and Lynda J.       Garrett.**
