Do household cleaning products hold the key causative agent for non-smoking women with reactive airway disease?

A 20-year European study reveals a startling truth: women who frequently clean at home or work experience significant lung damage over time. The study found that the decline in lung function among these women mirrors the impact of smoking a pack of cigarettes a day for 20 years, due to repeated exposure to toxic cleaning chemicals.
I found this to be very interesting, as my mom has reactive airway disease but never smoked. Never lived in a smoggy urban environment. But she did clean houses for many years, on top of cleaning our home.

This is why i make my own cleaning products based on a recipe from a professional cleaning book. I mix 1/2 cup of isopropyl alcohol, 1 cup of water, and 10 to 20 drops of essential oil (usually peppermint oil) and put in a spray bottle. Cheap to make and smells great. Healthier than store bought.
I know some recipes use vinegar instead of the alcohol but vinegar is conta indicated for granite.
My daughter has been cleaning homes for over 15 years. I know she uses "green" products but how safe are they? Who knows? This is what happens in many causes of illnesses and diseases. People are poisoned over the long term (years or decades) and assume they have caught this disease or that disease.
Actually it is the toxins causing the troubles and the damages...not the purported "disease" that the medical mafia loves to label people as having so they can pump you full of more toxic things like drugs.
The answer is to stop the poisonings and hope that it is not too late for the body to reverse the damages.
