Toxicodynamics into awareness by Our Stolen Future by Theo Colborn. Endocrine disrupting chemicals are known to accumulate in body tissue and are highly persistent in the environment. Many toxicants are known EDCs including pesticides, phthalates, phytoestrogens, some industrial/commercial products, and pharmaceuticals. These chemicals are known to cause endocrine disruption via a few different mechanisms. While the mechanism associated with the thyroid hormone receptor is not well understood, two more established mechanisms involve the inhibition of the androgen receptor and activation of the estrogen receptor. Certain toxicants act as endocrine disruptors by interacting with the androgen receptor. DDE is one example of
Color of chemicals the colors found in a flame test, are produced in a bead test, which is a qualitative test for determining metals. A platinum loop is moistened and dipped in a fine powder of the substance in question and borax. The loop with the adhered powders is then heated in a flame until it fuses and the color of the resulting bead observed. Color of chemicals The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the
