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.
History and the speculative collide with the modern world when a group of high school girls form a secret society after discovering they can communicate with boys from the past, in this powerful look at female desire, jealousy, and the shifting lines between friendship and rivalry. After her life is upended by divorce and a cross-country move, 16-year-old Saskia Brown feels like an outsider at her new school—not only is she a transplant, but she’s also biracial in a population of mostly white students. One day while visiting her only friend at her part-time library job, Saskia encounters a vial of liquid mercury, then touches an old daguerreotype—the precursor of the modern-day photograph—and makes a startling discovery. She is somehow able to visit the man in the portrait: Robert Cornelius, a brilliant young inventor from the nineteenth century. The hitch: she can see him only in her dreams. Saskia shares her revelation with some classmates, hoping to find connection and friendship among strangers. Under her guidance, the other girls steal portraits of young men from a local college’s daguerreotype collection and try the dangerous experiment for themselves. Soon, they each form a bond with their own “Mercury Boy,” from an injured Union soldier to a charming pickpocket in New York City. At night, the girls visit the boys in their dreams. During the day, they hold clandestine meetings of their new secret society. At first, the Mercury Boys Club is a thrilling diversion from their troubled everyday lives, but it’s not long before jealousy, violence and secrets threaten everything the girls hold dear.
