Описание: Could low-level exposure to polluting chemicals be analogous to exercise - a beneficial source of stress that strengthens the body? Some scientists studying the phenomenon of hormesis (beneficial or stimulatory effects caused by low-dose exposure to toxic substances) claim that that this may be the case. Is A Little Pollution Good For You? critically examines the current evidence for hormesis.
Описание: The global prevalence of neurodevelopmental disorders is accelerating. Numbers of children affected by an autism spectrum disorder (ASD) in the United States have reached 1 in 88 -- 1 in 56 among boys -- and even more children have developed attention deficit/hyperactivity disorders (ADHD). The burden of these disorders to individuals and society overall is enormous; ASD alone costs the United States a staggering $130 billion, with ADHD costs reaching similar heights. Genetic causes of these neurodevelopmental disorders cannot account for such radically increased rates of incidence. The causes must also implicate environmental chemicals, many of which have been shown to disrupt normal thyroid function. In this book, Barbara Demeneix makes the case that thyroid hormone signaling bridges the environment and gene programs needed for brain development--and that environmental chemicals that disrupt normal thyroid function pose significant risks to the inherited intelligence and mental health of future generations. The first chapter provides an historical overview of documented cases in which environmental pollution has caused IQ loss across populations. The following chapters explain the physiology of thyroid hormone action, the importance of iodine and selenium for thyroid hormone signaling and brain development, and why thyroid hormone is such a sensitive target for environmental pollution. The final chapters discuss the role of gene-environment interactions in neurodevelopmental disorders and address what can and must be done by individuals, associations, and decision-makers to staunch these epidemics.
Описание: One of every six children suffers from a neurodevelopmental abnormality of unknown cause. Environmental pollutants such as lead, mercury, and pesticides interfere with brain development, yet we do not test industrial chemicals for brain toxicity.

Описание:
Environmental pollution is one of humanity's most pressing issues and will remain so for the foreseeable future. Anthropogenic activity is disturbing natural cycles and generating pollutants that are altering the atmosphere, accumulating in the food chain and contaminating the world's soils, rivers and oceans. Human health and ecosystems continue to be damaged by toxic metals, persistent organic pollutants, radionuclides and other hazardous materials. The Elements of Environmental Pollution provides comprehensive coverage of this essential subject. It explains the key principles of pollution science, assesses human disturbances of natural element cycles and describes local and global pollution impacts, from smoggy cities, polluted lakes and toxic soils to climate change, ocean acidification and marine dead zones. The book is informed by the latest pollution research and benefits from numerous real-world examples and international case studies. A comprehensive glossary provides clear and concise explanations of key concepts.
This textbook will support teaching and learning in environment-related university courses and will be vital reading for anyone with an interest in environmental protection.
