A report in April of 1999 on ABC-TV's 20/20 disclosed an unnerving possibility,-- do the petrochemicals that make up plastic pose health risks to infants and children? As we know, baby bottles are made from plastic, so are teething rings, toys, why even juice liners and the insides of cans, are made from, or coated in, plastic.
Bisphenol A, (or BPA), was the chemical singled out in this particular study, reported on by ABC, and commissioned by the Consumer's Union. BPA, it seems, is a component of polycarbonate, a clear and rigid plastic, that is used in the manufacture of baby bottles.
In laboratory tests, Consumers Union, (the people who put out the Consumer's Report), found that small amounts of the additive BPA leach out of the plastic baby bottles and potentially may end up in babies milk. Although the amount of bisphenol A that ended up in the milk was "small"--one part per billion-- Dr. Edward Groth, a senior scientist at Consumers Union, explained, that even that "small" quantity was "close enough to levels that had" actual "effects on animals. . . . The effect that is of concern here is a disruption of the developmental process. This could affect intelligence. It could affect behavior. It could affect learning ability. It could affect reproductive ability, fertility many years after the exposure occurs."
