HORMONE DISRUPTION

PVC is a hard, ridged material. Think of PVC sprinkler pipes. In many instances a chemical must be added to make the PVC soft and pliable. As mentioned previously, common chemicals used to soften PVC are phthalates, fatty acids, and alcohols. Of special concern are certain which are known hormone disrupters. These chemicals mimic or interfere with our own delicate hormone system. As a class, phthalates are one of the most prevalent of the hormone disrupting chemicals

found in the environment.

Hormone disrupting chemicals can lead to a variety of health problems including developmental problems, reproductive problems, increased susceptibility to a verity of cancers, as well as broad implications in lower sperm count in men and fertility difficulties in women.
