For years, we have believed that long living chemicals of the organochlorine type were eventually degrading after we banned their use back in the 1970s. It was certainly a surprise to the environmental community to discover the chemicals were hitching rides on the winds and ocean currents and living on in the Arctic region. Not only were they present, but the amounts present in samples of various animals were staggering to scientists.These chemicals, which have incredible half lives, do not decay, but rather they accumulate in the tissue of whales, walrus, polar bears and other upper order mammals. Each time an animal eats another, a process known as biomagnification takes place, further increasing the dose in the next animal up the food chain. Since indigenous peoples to the Arctic eat what the sea provides, their bodies are laden with these chemicals. Once thought to be relatively harmless, it has been discovered that they are responsible for cognitive learning problems, immunity issues and a host of other problems. This book takes a critical look at what we have done and are continuing to do to the environment.It is a well written book, with science presented in a way that can be enjoyed by those with little scientific background. The data found in the book should be alarming, as we continue to produce a number of chemicals that we know little about. This book should be the wake up call for further intense testing of chemicals to insure we are not poisoning generations yet to be born with chemicals that appear, today, to be relatively innocuous.
