Developement of health risk rating scale for indoor airborne fungal exposure.
TLDR
Five sampling locations in Kolkata frequented by a heterogeneous human population, containing various types of fungal growth-promoting substances, were chosen as sampling locations where an Andersen Two-Stage Cascade Impactor was ran using Rose Bengal agar and Potato Dextrose agar media plates.Abstract:
This paper aims to quantify airborne fungal load in air-conditioned rooms and develop a health risk rating scale for different indoor environments. Five sampling locations in Kolkata frequented by a heterogeneous human population, containing various types of fungal growth-promoting substances (FGPS) like old documents, food items, waste hair, etc. were chosen as sampling locations where an Andersen Two-Stage Cascade Impactor was ran using Rose Bengal agar and Potato Dextrose agar media plates. Total spore load (CFU/m3), species diversity, species dominance, human exposure time, susceptible age and FGPS were considered the risk factors for this study. A risk rating scale was developed after evaluating the relative importance of these different factors in relation to human health. The most dominant genera were Aspergillus, followed by Penicillium. Maximum CFU was observed at library, followed by computer room.read more

A technique for the measurement of attitudes
TL;DR: The instrument to be described here is not, however, indirect in the usual sense of the word; it does not seek responses to items apparently unrelated to the attitudes investigated, and seeks to measure prejudice in a manner less direct than is true of the usual prejudice scale.

TL;DR: Improved non-culture-based diagnostics are needed to expand the potential for preemptive (or early directed) therapy and improve diagnostic, preventive, and therapeutic strategies is necessary to reduce the considerable morbidity and mortality associated with IC.

New sampler for the collection, sizing, and enumeration of viable airborne particles.
TL;DR: From these and many other references it is obvious that any instrument used to assess the health hazard or infection potential of particulate aerosols should determine the number and the size3 of the airborne particles.

Indoor airborne fungal spores, house dampness and associations with environmental factors and respiratory health in children
TL;DR: Children living in a damp house are more likely to suffer from respiratory symptoms and it has been suggested that exposure to fungi is an important contributing factor, but more knowledge is needed about underlying mechanisms.

TL;DR: It is concluded that prolonged and intense exposure to toxigenic S. chartarum and other atypical fungi was associated with reported disorders of the respiratory and central nervous systems, reported Disorders of the mucous membranes and a few parameters pertaining to the cellular and humoral immune system, suggesting a possible immune competency dysfunction.
