EDCs and me

Endocrine disrupting chemicals (EDCs) also known as hormone disruptors are chemicals which interfere with the natural hormones in our bodies, our body’s chemical messengers.

As our hormones are released by the endocrine glands, these chemicals are sometimes also called endocrine disrupting chemicals or EDCs. This means they interfere with how our bodies function, causing problems with reproduction, behaviour, brain function and the immune system. Some research suggests that they can do this even if we are exposed to extremely small amounts (the so-called ‘low dose’ effect).

EDCs have the ability to mimic our hormones or interfere with the hormonal systems, in particular with the thyroid hormones and sex hormones.

EDCs can be found in:

  • Preservatives such as certain parabens in e.g. cosmetics and household cleaners;
  • Plastic softeners such as some phthalates in e.g. flooring and shoes;
  • Bisphenol-A used to make polycarbonate plastic for e.g.  DVDs, and used in food cans and in thermal paper

These hormone disruptors have been linked with several health problems including the deterioration of male reproductive health, the increased incidence of hormone related cancers and the increase in cardiovascular disease, obesity and diabetes.
