Track & Field
Track and field events demand a high degree of strength, stamina, and flexibility. Shot put, hammer throw, long jump, as well as many other track and field events, can put intense strain on certain muscle groups. Injuries can strike suddenly or gradually build up over time. Explore the ways in which athletes must prepare themselves for meets, maintain physical fitness, and prevent injury. The book is also a guide to the physical and mental preparation that athletes must undergo before competing or training, some of the most common injuries sustained during track and field events, and the dangers of using performance-enhancing drugs. You'll find a wealth of practical advice, including: • How to treat sprains and strains. • How to stretch effectively before a race or field event. • Why dietary supplements can be more harmful than helpful. • What foods contain the nutrients athletes need to maintain health.
Mercury in the Environment
Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. Mercury in the Environment follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.
