The first cause for concern, say the authors, is that certain "known
toxicants" - including formaldehyde, a substance known to cause cancer
- are used legally in food contact materials. Plastic bottles used for carbonated drinks,
for example, usually contain low levels of formaldehyde.
Another point the authors make is that hormone production-disrupting
chemicals, such as bisphenol A (BPA), tributyltin, triclosan and
phthalates, can also be present in FCMs.
