From CNN: 5 toxins that are everywhere

A growing body of research is linking five chemicals -- among the most common in the world -- to a host of ailments, including cancer, sexual problems and behavioral issues.

We encounter them every day -- in plastic bottles, storage containers, food wrap, cans, cookware, appliances, carpets, shower curtains, clothes, personal care products, furniture, television sets, electronics, bedding, cushions and mattresses. In short, every room in almost every house in the United States is likely to contain at least one of these chemicals, many of which did not exist a century ago.

They are bisphenol A, or BPA; phthalates; PFOA; formaldehyde; and polybrominated diphenyl ethers, or PDBEs. Tests reveal most of us now carry them in our bodies, but are they putting our health -- and the health of our children -- in jeopardy?

BPA-free is not what it's cracked up to be

...Appleton, a specialty paper company, markets a BPA-free thermal paper that uses Bisphenol S instead. The Environmental Protection Agency has a voluntary program that is evaluating BPS and 17 other possible substitutes for thermal paper, but has not yet completed its analysis. Until it does, it will not endorse any alternatives.

In the few, limited tests conducted outside the United States, BPS shows estrogenic activity — not as strong as BPA, but not a good sign. BPS is now used in the United States to make PES (polyethersulfone) plastic. Some baby bottles marketed as BPA-free use PES plastic....

....Bisphenols are shaping up to be a dysfunctional family of chemicals. BPAF is BPA’s fluorinated twin. It is used in electronic devices, optical fibers and more. New studies have found BPAF to be an even more potent endocrine disrupter than BPA. Bisphenol B and Bisphenol F are other variants used instead of BPA in various products. In the limited testing done on those chemicals in other countries, scientists found Bisphenol B to be more potent than BPA in stimulating breast cancer cells.

Plastic bottles raise hormonal activity of bottled spring water

Plastic bottles can further contaminate natural spring water with estrogen active compounds, report researchers who tested and compared water from the same sources but was bottled in either glass or plastic.

The water in the plastic containers triggered up to 90 percent more activity in the human cell assays used than the water in the glass containers. Hormone activity was measured by the increase in growth rate of the exposed human breast cancer cells – which are sensitive to estrogen hormones.

The results suggest that some springs used by water bottlers initially contain estrogenic chemicals, but the process of bottling in plastic further increases the waters estrogenic potential.

Replacement for BPA is also found to have negative health effects

An animal study finds for the first time that another widely used phthalate affects development when exposure occurs in the womb and early life. It is also the first to show the chemical can affect brain development, too. DINP – a phthalate that is increasingly used in plastic products – caused similar changes in the male reproductive system as other types of recently banned – but more potent – phthalates.
