This chemical contaminates the drinking water of an estimated ten million Californians, and as of 2009 it has been found in 92 public water systems and 297 drinking water sources at levels at or above 4 parts per billion (ppb) ... Neonates and infants are most susceptible, both due to susceptibility to irreversible neurological effects from perchlorate-associated iodine deficiency in the central nervous system, and due to increased exposure because of a greater relative consumption of fluids as a proportion of body weight. Breastfeeding neonates and infants must also be considered susceptible due to the evidence that perchlorate is actively sequestered in breast milk ... That same study and others have reported elevated levels of perchlorate in breastmilk, above levels found in maternal urine or in local drinking water."<br /><br />https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0B6chTY7Cm<br />FMcNjc3ZTYwMjQtOGY3OS00YmQ1LTlmYTQtYmI1ZTJ<br />iOGJmZDA2&hl=en&auth<br />key=CLHhx0wAllen Hengsthttps://www.blogger.com/profile/09528014750219367029noreply@blogger.com
