Hospital cleaning products can do harm
Cleaning products used in hospitals may pose a health risk to both cleaning staff and patients, U.S. researchers said.
Study leader Anila Bello of the University of Massachusetts Lowell Sustainable Hospitals Program, and Melissa Perry of the Harvard School of Public Health in Boston, investigated the cleaning materials and techniques used in six Massachusetts hospitals.
Cleaning products may impact worker, and possibly patient, health through air and skin exposures, the researchers said in a statement.
The ingredients of concern identified in our study included quaternary ammonium chlorides or 'quats' that can cause skin and respiratory irritation. Some products contained irritant glycol ethers that can be absorbed through the skin, as well as ethanolamine -- another respiratory and dermatological irritant. We also found several alcohols such as benzyl alcohol, ammonia and several phenols, all of which can exert harmful effects on the body.
The pilot study is published in the journal Environmental Health.
