title: Environmental air pollution in an intensive care unit for nephrology and dialysis.
abstract: The quality of indoor air depends on external pollutant concentrations and on internal sources, such as heating and air conditioning systems, building materials, ventilation, cleaning products, personnel and their activity. This study assessed environmental air pollution in an intensive care unit (ICU) for nephrology and dialysis. Air-dispersed particulate pollution was measured using a gravimetric method and spectroscopic photocorrelation. Microbiological pollution was evaluated by passive and active collection. Particulate concentrations exceeded recommended limits in some of the environments. There was a prevalence of small particulates, which are the most harmful type of all. An overall evaluation of bacterial pollution showed low levels of contamination in some of the rooms. In none of the environments we were able to detect pathogens such as Aspergillus fumigatus, methycillin-resistant Staphylococci or toxin-producing fungi.
