Bisphenol A (BPA) is a chemical found in many plastics (including baby bottles, plastic microwave food containers & canned food linings). It is a known endocrine or hormone disruptor & is implicated in diseases ranging from infertility, obesity, breast and prostate cancer, to diabetes, thyroid malfunction & attention deficit syndrome.

Bisphenol B (BPB).


Estrogenic activity (EA) can be caused by human made endocrine disrupting compounds (such as BPA & phthalates). See EDCs


Endocrine disrupting chemicals or endocrine disrupting compounds (EDCs) can mimic the hormone estrogen, a female sex hormone, & "interfere with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body that are responsible for the maintenance of homeostasis (normal cell metabolism), reproduction, development, and/or behavior."

The term "dioxin" is commonly used for a family of toxic chemicals that share a similar chemical structure & induce harm through a similar mechanism. Dioxins have been characterized by EPA as likely human carcinogens & are anticipated to increase the risk of cancer at background levels of exposure.

Latex is natural rubber that is made from the sap of the Brazilian rubber tree. It contains a protein that some people can be allergic to. For most, it is harmless.

Lead is a toxic metal that may cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Children six years old and under are most at risk.

Melamine, a chemical used to make plastics, pesticides, fertilizers & even commercial fish feed, has in some cases been added to some milk products to falsely increase the apparent level of protein. Melamine alone is of very low toxicity (comparable to table salt), but when combined with cyanuric acid, animal studies have suggested that kidney problems occur. Melamine dishware is often referred to as melamine, but is actually a polymer of melamine & formaldehyde. Melamine can leach into food & beverages (especially those that are acidic or warm).

N-nitrosamines (or nitrosamines), many of which are carcinogens, can occur when using some rubber baby bottle teats. They can migrate into foods that contact the teat, such as milk & infant formula.

Perfluorinated Chemicals (PFCs) are widely used as industrial surfactants & are used in numerous consumer products for their stain/water resistant properties. PFCs are persistent, bioaccumulative & toxic chemicals. They are suspected of causing liver damage, some cancers, alterations in thyroid hormone levels & may affect cell growth.

Phthalates (called "plasticizers") are a group of chemicals used to make plastics like PVC more flexible & as solvents. Phthalates have been found to disrupt the endocrine system. Several phthalate compounds have caused reduced sperm counts, testicular atrophy & structural abnormalities in the reproductive systems of male test animals. Some studies link phthalates to liver cancer.

It's often reported that no other plastic presents such a direct environmental & human health threat as Polyvinyl Chloride (PVC) does throughout its lifecycle. Greenpeace has pushed for the cessation of PVC production as dioxin is created from the manufacture & incineration of the substance.  Also, items made from PVC will retain their form for decades & breakdown that occurs is just granulation - pieces simply become smaller (which animals can ingest).  PVC is also difficult to recycle given the presence of additives including heavy metals such as lead & cadmium. Currently under 1% of PVC is recycled.

Volatile Organic Compounds (or VOCs) are emitted as gases from certain solids or liquids. VOCs are emitted by a wide array of products numbering in the thousands (they are widely used as ingredients in household products). They include a variety of chemicals, some of which may have short- and long-term adverse health effects like eye, nose, and throat irritation; headaches, loss of coordination, nausea; damage to liver, kidney, and central nervous system. Some VOCs can cause cancer in animals; some are suspected or known to cause cancer in humans.
