- BPAs are toxins found in plastics, including water bottles and have been linked to disruption in the production of eggs and sperm
- The FDA says the levels in widely used products are generally ‘safe’
- However, the agency banned the use of these chemicals in baby bottles and sippy cups in 2012
- Now Washington State University research devised a new ‘direct’ way of testing human exposures to the chemicals
- They found they exceed the FDA’s ‘safe’ levels by as much as 44-fold
Humans are exposed to far more hormone-disrupting chemicals than previously thought, according to a new study.
Patricia Hunt, the researcher at Washington State University who first discovered that BPA, a dangerous toxin in plastics, can cause cancer and other diseases and disorders, has now developed a more accurate method of measuring it.
In a study published today, Dr Hunt reveals the new tool shows the ‘safe’ limit of BPA stipulated by the US Food and Drug Administration is flawed.
In fact, it is 44 times higher than what Dr Hunt considers safe.
‘This study raises serious concerns about whether we’ve been careful enough about the safety of this chemical,’ Dr Hunt, a corresponding author on the paper, said.
‘What it comes down to is that the conclusions federal agencies have come to about how to regulate BPA may have been based on inaccurate measurements.’
The amount of BPA the FDA considers acceptable varies based on the product.
Broadly, it claims that the chemicals are ‘safe’ and that people are exposed to such low doses of them that they’re not considered toxic.
However, in 2012, it amended its regulations and banned the use of BPA in baby bottles and sippy cups.
