Emerging research has found that, in laboratory studies, <"http://www.yourlawyer.com/practice_areas/toxic_substances">bisphenol A (BPA) significantly affects reproductive health at levels that are either the same or even lower that those believed not to cause adverse effects. The research, said Science Daily, was conducted by the North Carolina State University and the National Institute of Environmental Health Sciences (NIEHS).
BPA is an estrogen-mimicking, hormone interrupting chemical that hardens chemicals. The toxin can be found in baby bottles, sippy cups, water bottles, canned foods, and countless other products.
Despite industryâ€™s assertions to the contrary, BPA has been linked to a wide variety of adverse effects, namely: Increased risks of brain, reproductive, cardiac, and immune system diseases and disorders; problems with liver function testing; interruptions in chemotherapy treatment; links with serious health problems based on over 200 studies which found it to have negative effects at doses lower than the FDAâ€™s current standards; retention in the body longer than previously believed; leeching into liquids being held in containers regardless of whether the containers are or are not heated; and longer lasting damage, which can be passed to future generations.
The recent research found that when female rates were exposed to a BPA dose of 50 micrograms per kilogram of body weight (Âµg/kg) in their first four days of life, they experienced early puberty, with female rats developing â€œsignificant ovarian malformations and premature loss of their estrus cycle,â€ reported Science Daily. “The 50 mg/kg level is important,” says lead researcher Dr. Heather Patisaul, “because it is equivalent to the U.S. Environmental Protection Agency’s ‘Lowest Observable Adverse Effect Level’ for BPA. So, by definition, we should not have seen significant effects at or below this level, but we did,” Science Daily quoted.
According to Patisaul, an assistant professor of biology at NC State, the 50 Âµg/kg level is of importance because it represents the EPA’s listed reference dose for BPA, or that amount a person can be exposed to daily, and for a lifetime, with no adverse effects, said Science Daily.
BPA is banned in Connecticut, Minnesota, Chicago, and New Yorkâ€™s Suffolk County. Wisconsin just became the third state to introduce a bill to ban BPA-containing baby bottle and sippy cup sales for children and, earlier this month, California voted on a similar bill that is in the Assembly. Key members in the U.S. House and Senate introduced legislation for a federal ban on BPA in all food and beverage containers, and 24 states have bills in the works to restrict the toxin; Canada was the first country to announce plans to ban BPA, calling it a toxin, and newly appointed U.S. Food & Drug Administration (FDA) commissioner, Dr. Margaret Hamburg, said the agency is reconsidering its decision that BPA is safe at current levels, especially those found in baby bottles, a decision for which the agency has faced fierce criticism.
Meanwhile, earlier this month we wrote about disturbing plans being devised by some manufacturers in whose best interest it is to continue to use and promote the BPA. The manufacturers have been trying to figure out how to stem government bans and allow BPA in the items they produce.
