With the holiday season upon us, it may be that you plan to take your fancy clothes to the dry cleaners to keep them looking lovely for holiday parties. Before you do that, you should know that Environmental Defence has put out a new report about the dangerous chemicals used in dry cleaning. So how is dry cleaning toxic to your health?
The most common dry cleaning chemical called PERC (perchloroethylene) is used as a solvent and stain remover, but is very toxic to human health and the environment.
“Short-term exposure to PERC can cause symptoms like dizziness, headaches, nausea, skin, eye, and lung irritation. Long-term exposure has been linked to various forms of cancer and reproductive health issues. When spilled on the ground, the chemical can even find its way into our drinking water. Studies suggest an association between PERC exposure from drinking water and increased risk of several cancers, including lung cancer, breast cancer, non-Hodgkin’s lymphoma, and leukemia.” (Environmental Defence Dry Cleaning Report, p.4)
This chemical is dangerous to employees of dry cleaners, as well as residents living near dry cleaning operations, and because it can contaminate water, the hazards can be very widespread.
Right now, the US has started taking steps to limit the exposure to PERC, but Canada is lagging behind in its regulations.
The problem with banning PERC across the board, is that there are still lots of toxic alternatives out there, like hydrocarbon cleaning, that would still cause environmental and health hazards.
BUT – there ARE non-toxic alternatives available: wet cleaning and liquid carbon dioxide. Wet cleaning is recommended by Environmental Defence because it is the safest and most cost-effective option. Liquid carbon dioxide is much more costly, therefore not economically feasible.
So what can be done?
Environmental Defence has several recommendations for governments to make the shift to non-toxic, environmentally friendly wet cleaning.
As customers, we can ask our dry cleaners about the availability of wet cleaning methods.
