“…Bioburden assessment with EDCs has been previously carried out in occupational environments, such as schools [3], health care centers [26] and swine farms [27], as well as in residential settings of Portuguese coastal cities [3,4]. However, outdoor fungi and bacteria are mainly affected by local climate conditions [28], while in indoor environments different factors, such as the thermal comfort, dwelling characteristics and occupant activities, may play a key role in bioburden [3,4,29,30]. Thus, results of a given region may not be generalizable to other target populations.…”
