- Migration/leaching of chemicals from packaging materials,
- Deliberate addition of chemicals used as preservatives, flavorings, scents, texture enhancers, coloring agents etc.4,
- Contamination by unknown compounds formed by chemical reactions among multiple intentionally used constituent chemicals18.
- Incidental contamination via migration/leaching of chemicals from harvesting and processing17.
- Home food-handling can also accelerate migration through heating, microwaving, ultraviolet light exposure (including fluorescent lighting) and the contact of oils and alcohols with plastics.

12.2 PRELIMINARY STUDIES
Recent dietary interventions16, 17,28 have found significant reductions in the targeted chemicals measured concurrent with study designs to replace pre-prepared meals and other foods with known levels of endocrine disruptors with a fresh, home-prepared
- time-limited (3 -16 days),
- involved relatively small numbers of test subjects (20 – 40),,
- imposed very general dietary restrictions (whole diet, fresh foods)
