Toxicological Effects of Methylmercury


Book Description

Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.







Dynamics of Mercury Pollution on Regional and Global Scales


Book Description

This book provides a comprehensive overview of the different dynamic patterns involved in the redistribution of mercury in the global environment, and its impact on human health and ecosystems. Increasing mercury usage and the lack of emission control policy, especially in fast developing countries, represent a complex environmental and political issue that can only benefit from more accurate measurement.

Diagnosis


Book Description

One morning in 2000, Dr. Jane Hightower walked into her exam room to find a patient with disturbing symptoms she couldn’t explain. The woman was nauseated, tired, and had difficulty concentrating, but a litany of tests revealed no apparent cause. She was not alone. Dr. Hightower saw numerous patients with similar, inexplicable ailments, and eventually learned that there were many more around the nation and the world. They had little in common—except a healthy appetite for certain fish. Dr. Hightower’s quest for answers led her to mercury, a poison that has been plaguing victims for centuries and is now showing up in seafood. But this “explanation” opened a Pandora’s Box of thornier questions. Why did some fish from supermarkets and restaurants contain such high levels of a powerful poison? Why did the FDA base its recommendations for “safe” mercury consumption on data supplied by Saddam Hussein’s Ba’athist extremists? And why wasn’t the government warning its citizens? In Diagnosis: Mercury, Dr. Hightower retraces her investigation into the modern prevalence of mercury poisoning, revealing how political calculations, dubious studies, and industry lobbyists endanger our health. While mercury is a naturally occurring element, she learns there’s much that is unnatural about this poison’s prevalence in our seafood. Mercury is pumped into the air by coal-fired power plants and settles in our rivers and oceans, and has been dumped into our waterways by industry. It accumulates in the fish we eat, and ultimately in our own bodies. Yet government agencies and lawmakers have been slow to regulate pollution or even alert consumers. Why? The trail of evidence leads to Canada, Japan, Iraq, and various U.S. institutions, and as Dr. Hightower puts the pieces together, she discovers questionable connections between ostensibly objective researchers and industries that fear regulation and bad press. Her tenacious inquiry sheds light on a system in which, too often, money trumps good science and responsible government. Exposing a threat that few recognize but that touches many, Diagnosis: Mercury should be required reading for everyone who cares about their health.




Reducing Environmental Cancer Risk


Book Description

Though overall cancer incidence and mortality have continued to decline in recent years, cancer continues to devastate the lives of far too many Americans. In 2009 alone, 1.5 million American men, women, and children were diagnosed with cancer, and 562,000 died from the disease. There is a growing body of evidence linking environmental exposures to cancer. The Pres. Cancer Panel dedicated its 2008¿2009 activities to examining the impact of environmental factors on cancer risk. The Panel considered industrial, occupational, and agricultural exposures as well as exposures related to medical practice, military activities, modern lifestyles, and natural sources. This report presents the Panel¿s recommend. to mitigate or eliminate these barriers. Illus.
