...concerns from clinicians, housekeeping staff, and nurses about various cleaning agents,” said lead researcher Anila Bello, a research fellow in exposure and epidemiology at the Harvard School of Public Health. Some hospital workers had said that they had experienced exacerbated asthma symptoms, while others complained of skin irritation...
Researchers sought to identify ingredients in glass, bathroom, and general-purpose cleaners that may cause respiratory distress and skin irritation and then gauge the potential for exposure to these ingredients during common cleaning tasks...

Rather, both sensations were rooted in the spinal cord. (See pictures of an X-ray studio...
