  • Chlorine kills bacteria, including disease-causing organisms and the nuisance organism, iron bacteria. However, low levels of chlorine, normally used to disinfect water, are not an effective treatment for giardia cysts. A chlorine level of over 10 mg/1 must be maintained for at least 30 minutes to kill giardia cysts. -- http://ohioline.osu.edu/b795/index.html is the front page of this bulletin

From that website: The Endocrine Disruption Exchange, Inc. is the only organization that focuses primarily on the human health and environmental problems caused by low-dose and/or ambient exposure to chemicals that interfere with development and function, called endocrine disruptors. ... TEDX's work focuses on the endocrine system, which is the exquisitely balanced system of glands and hormones that regulates such vital functions as body growth, response to stress, sexual development and behavior, production and utilization of insulin, rate of metabolism, intelligence and behavior. Hormones are chemicals such as insulin, thyroxin, estrogen, and testosterone that interact with specific target cells. The interactions occur through a number of mechanisms, the easiest of which to conceptualize is through a lock and key arrangement.

• Our Stolen Future: Are We Threatening Our Fertility, Intelligence, and Survival?--A Scientific Detective Story, Theo Colborn, Dianne Dumanoski, John Peter Meyers. Plume-Penguin Publishing, 1997, ISBN 0-452-27414-1., ISBN13: 9780452274143. This book is a seminal work on endocrine disruptors (chemical contaminants having impact at extremely low levels in the environment).
  Recommended by Daniel Friedman, this book is a critical update to the landmark Silent Spring by Rachel Carson and discusses the effects of minute trace amounts of chemical contaminants in the environment. The text "Identifies the various ways in which chemical pollutants in the environment are disrupting human reproductive patterns and causing such problems as birth defects, sexual abnormalities, and reproductive failure. Reprint. Tour. NYT."
  Amazon.com Review: By O T (Ontario, BC) - 'Our Stolen Future' is a great introduction to one of the most important scientific discoveries in our time. Having recently completed a thesis project at university on Endocrine Disruptors, I have reviewed hundreds of papers on the subject. This book is a good clear overview of the scientific literature on EDs. The authors are experts - Theo Colborn is largely responsible for creating the field by bringing together diverse researchers so they could see the big picture of their work. Many of the principle investigators are interviewed and quoted at length on the way chemicals participate in and interfere with delicate hormonal systems in animals (including humans). The major accomplishment of the book is to make an easy-to-follow story out of complex research. Many resources are available to help you assess the reliability of this story, and the best thing to do if you have any doubts is read review articles in scientific journals (which are easier to understand than technical papers). The Physicians for Social Responsibility (PSR) have a guidebook for health-care professionals on Endocrine Disruptors, and the US EPA has many reports on the matter. Beware of people or websites who try to 'debunk' this book (or the science behind it) by simply declaring it false, flawed or disproven. There is far too much supporting research for so simple a refutation.
  OPINION: Significant and discussed in this book is the observation that at certain critical points in the development of animals, presumably including humans, exposure to extremely low levels of endocrine disruptor chemicals (EDC's) (such as BPA - Bisphenol-A or BPA, Diethylstilbestrol - DES, dioxins, PCBs, and chemicals used in the production of certain cleansers, dyes, flame retardants, plastics, pesticides, white papers ) perhaps just a few molecules, or in the parts per trillion, is sufficient to cause disruption of the animal's development, including proper sex differentiation, or the lack of it that produced androgynous ducks unable to reproduce under such conditions.
  A endocrine disruptor is a synthetic chemical compound that mimics natural hormones when it is taken into the body of a human or other animal. It "disrupts" the endocrine system by turning on or off normal chemical signals that in turn can affect normal hormone levels, bodily functions, and significantly, the development of embryos. Further, unlike naturally occurring hormones ingested, for example from plants (phytoestrogens), synthetically-generated hormones accumulate in the body and can have a half-life of decades or longer.
  One significance of this finding includes the observation that an important medical effect that occurs with exposure to chemicals in extremely low concentrations means that experiments to test for correlations between chemical exposure and subsequent serious medical problems will be deeply flawed if, for example, the experimental design does not include testing for the presence of the chemical at extremely low levels. A related concern is that even if harmful effects from exposure to extremely low concentrations of an endocrine disruptor are occurring, teasing out and proving that relationship can be also extremely difficult.
• Silent Spring, Rachael Carson, Mariner Books; Anv edition (October 22, 2002), ISBN-13: 978-061824906.
  Amazon.com Review: Silent Spring, released in 1962, offered the first shattering look at widespread ecological degradation and touched off an environmental awareness that still exists. Rachel Carson's book focused on the poisons from insecticides, weed killers, and other common products as well as the use of sprays in agriculture, a practice that led to dangerous chemicals to the food source. Carson argued that those chemicals were more dangerous than radiation and that for the first time in history, humans were exposed to chemicals that stayed in their systems from birth to death. Presented with thorough documentation, the book opened more than a few eyes about the dangers of the modern world and stands today as a landmark work.
