Book Description
One egg from each of 440 clutches of eggs of 19 species of Alaskan seabirds collected in 1973-76 was analyzed for organochlorine residues. Both frequency of occurrence and concentration of residues in the eggs differed geographically and by species, apparently reflecting non-uniform distribution of organochlorines in the environment, dissimilar feeding habits and migration patterns of the species, or metabolic differences among the species.

Reliability of Kill and Activity Estimates in the U.S. Waterfowl Hunter Survey
Author: Leigh M. Couling
Publisher:
ISBN:
Category : Hunting surveys
Languages : en
Pages : 298
Book Description
A mail questionnaire survey of waterfowl hunters is conducted each year in the United States to provide information on waterfowl kill and hunter activity. We carried out a study using data from the 1971-73 and 1972-73 hunting seasons to determine the effectiveness of the present U.S. sampling and estimation techniques, and a number of modifications in both sampling and analysis is recommended.

Handbook of Chemical Risk Assessment
Author: Ronald Eisler
Publisher: CRC Press
ISBN: 9781420032741
Category : Science
Languages : en
Pages : 792
Book Description
Written over a period of 17 years, the Handbook of Chemical Risk Assessment exhaustively examines and analyzes the world literature on chemicals entering the environment from human activities. The three volumes cover chemicals recommended by environmental specialists of the U.S. Fish and Wildlife Service and other resource managers. The choices were based on the real or potential impact of each contaminant and on the knowledge available about their mitigation. The information for each chemical includes source and use; physical, chemical, and metabolic properties; concentrations in field collections of abiotic materials and living organisms; deficiency effects; lethal and sublethal effects; and proposed regulatory criteria for the protection of human health and sensitive natural resources. Each chapter selectively reviews and synthesizes the technical literature on a specific priority contaminant and its effects on the environment. Successful risk assessment relies heavily on extensive and well-documented databases. They often include too much - or too little - information about too many chemicals. Of the hundreds of thousands of chemicals discharged into the environment, only a small number have sufficient information to attempt preliminary risk assessment. Sold only as a three volume set, the Handbook of Chemical Risk Assessment provides you with the exact amount of information you need in a single resource.
