Image: www.metaefficient.comIn recent years there have been numerous studies regarding drinking water around the world. In most cases these studies have revealed that there are a large number of pharmaceutical ingredients present.
In 2004 the Canadian Government released its findings from its first study of pharmaceuticals in Canadian drinking water. The test samples were taken near 20 water treatment plants in Southern Ontario. Nine different drugs were found in the samples, ranging from painkillers to Prozac. Testing of drinking water in Philadelphia revealed that 56 pharmaceuticals or byproducts were present in treated drinking water. And the New York State health department tested the source of the city's water and found heart medicine, infection fighters, estrogen, anti-convulsants, a mood-stabilizer, and a tranquilizer.
So how is all of this getting into our drinking water?
Living in a society where it is possible to pop a pill for any pain or ailment is the primary pollution problem. IMS health global services records show that in 1999 the world drug consumption amounted to $342 billion and in 2006 the number almost doubled to $643 billion. A significant proportion of the drugs that we consume are designed to breakdown slowly and are excreted through urine without being fully metabolized by our bodies, and end up in municipal waste water. The human body is able to metabolize 80% of drugs such as the pain-reliever acetaminophem and the antidepressant fluoxetine; however, chemotherapy (methotrexate), diabetes (metformin), and high blood-pressure (atenol) products are excreted practically unchanged, with the body only absorbing 10-20% of the drug.
What are the effects?
The effects on the human body are still widely unknown; however, environmental effects are already visible. Pharmaceuticals seeping into the waterways are disrupting wildlife. The most visible and documented effect is the feminization of male fish. It has also been noted that fish that are exposed to an anti-depressent drug startle less quickly and impairs its ability to eat. There is growing scientific concern that the ingestion of certain drugs, or combination of drugs, may harm humans over decades of consumption through water. There has been speculation over the possible long term effects from the various drugs: chemotherapy medication could act as a powerful poison, hormones could hamper reproduction and development, depression and epilepsy medication could damage the brain or change behavior, and antibiotics could allow human germs to mutate into more dangerous forms.
What can we do?
Some companies, mainly in Europe, are beginning to use 'Ecolabeling'. This labling can be used on a range of products from over the counter medication to shampoo and house cleaners. The lables provide consumers with trustworthy information regarding the ecological soundness of the product.
If you live in Canada look for Product take-back programs ( www.medicationsreturn.ca)in your area. These programs accept expired or unused medications for environmentally safe disposal.
The two most important steps that we need to take is to educate ourselves and share our knowledge with others. And most importantly reduce your own personal medical consumption. Next time you are about to pop a pill think about this: "Studies show that half the antibiotics prescribed by General Practitioners surgeries are unnecesary. Likewise more than 30 percent of pills work because of a placebo effect: the actual chemicals do nothing" (ECOLOGIST May 2009).
