Book Description
Poisoning of North American waterfowl resulting from the ingestion of lead shot by ducks, geese, and swans causes an estimated annual mortality of 2% to 3% of the population. To alleviate this problem the search for a suitable substitute for lead has been underway since the early 1950's. Proposed substitutes for lead shot were evaluated in a series of acut toxicity tests with pen-reared mallards. Most candidate materials were as toxic to ducks as commercial lead shot. Coating or alloying lead with other materials only delayed mortality among dosed ducks.

Book Description
This report reviews the available information on the use, environmental fate, and toxicity of spent lead shot and lost lead fishing weights. The report begins with a summary of information on the production, import, and use of lead shot and fishing sinkers in Canada. It then discusses the fate of these products in the environment, including chemical transformation of metallic lead in the environment, lead concentrations in soils and biota, and factors affecting the environmental mobility of lead compounds. The next section assesses the toxicity of lead shot and sinkers to waterfowl and non-waterfowl species, effects of lead shot ingestion in cattle, and human health concerns about hunting with lead shot. The report ends with a discussion of options for managing the negative impacts of those products, including using alternatives to lead, restricting use of lead shot, and alternative fishing sinker products.

Book Description
Wing bones of 4,190 ducks of seven species collected in 1972 and 1973 were analyzed for lead to provide a base line for lead burdens and to determine geographic patterns of lead exposure in these species. Lead residues ranged from trace amounts to 361 ppm and reflected the history of exposure to lead from ingested shotshell pellets and other sources. Wing bones of adults contained higher residues than did those of immatures. Levels were lower in birds from the Central Flyway than in those from other flyways.

Book Description
Mallard ducks (Anas platyrhynchos) were given either 0, 2, or 4 No. 6 lead shot in combination with 4 grit treatments; no grit, coarse sand, mica granite, and crushed oystershell. Each combination was replication three times. Ducks were maintained on a diet of whole corn. An analysis of variance indicated no significant differences in mortality in relation to grit type, but a significant difference (at 0.05 level) in mortality between the lead shot doses. Oystershell grit apparently reduced mortality of ducks dosed with 4 shot but not to a degree statisticallty significant. In all treatments, mortality was closely associated with shot retentiion. Ducks retaining shot for 2 weeks usually died.

Book Description
Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.
