Exposure Levels Of Airborne Fungi, Bacteria, And Antibiotic Resistance Genes In Cotton Farms During Cotton Harvesting And Evaluations Of N95 Respirators Against These Bioaerosols, Atin Adhikari, Pratik Banerjee, Taylor Thornton, Daleniece Higgins, Caleb Adeoye, Sonam Sherpa

The USA is the third-leading cotton-producing country worldwide and cotton farming is common in the state of Georgia. Cotton harvest can be a significant contributor to airborne microbial exposures to farmers and nearby rural communities. The use of respirators or masks is one of the viable options for reducing organic dust and bioaerosol exposures among farmers. Unfortunately, the OSHA Respiratory Protection Standard (29 CFR Part 1910.134) does not apply to agricultural workplaces and the filtration efficiency of N95 respirators was never field-tested against airborne microorganisms and antibiotic resistance genes (ARGs) during cotton harvesting. This study addressed these two information gaps. …

Public Exposure To Outdoor Bioaerosols In Particulate Matter In Las Vegas: Daily And Seasonal Variations, Karey Renee Fortier
Public Exposure To Outdoor Bioaerosols In Particulate Matter In Las Vegas: Daily And Seasonal Variations, Karey Renee Fortier

Bioaerosols are airborne particles of biological origin including viruses, bacteria, pollen, fungi, and fragments of their metabolic products. Bioaerosol exposure may represent a health risk, in particular for risk groups such as immunosuppressed persons, and those suffering from allergies or respiratory diseases. Bioaerosols of sizes
This study seeks to assess outdoor bioaerosol number concentrations and size distributions in Las Vegas, NV, as the first step in understanding their health risks. PM2.5 and PM10 were collected on black polycarbonate filters for 24-hour duration using MiniVol air samplers on UNLV campus in the spring and fall of 2017. Bioaerosols in these samples …
A Comparison Of Outdoor Bioaerosol And Particulate Measurements In Las Vegas, Tanviben Yogeshkumar Patel

The urbanization of the Las Vegas Valley has turned the desert into a green oasis by introducing many non-native plant species, some of which are allergenic. Outdoor bioaerosols consist of microorganisms, pollen, spores, and other agents that could cause infections or affect the health of humans. Studies have suggested that exposure to bioaerosols through inhalation can lead to various human health risks. Typically, one monitoring station is established per city to obtain pollen and mold counts for an entire metropolitan area, and the site may not be representative of community exposures. The objective of this study was to measure and …
Bioaerosol Exposures From Three Utah Cattle Operations, Clark Evans
Bioaerosol Exposures From Three Utah Cattle Operations, Clark Evans
Graduate Theses & Non-Theses
Bioaerosol is a generic term used to describe dusts that are produced by and or contain biological material. These dusts can potentially contain the following hazardous agents; bacteria, viruses, bacterial endotoxins, and/or mycotoxins from mold spores. Respiratory inflammation, allergies, cancers, and infectious diseases can occur from exposure to a variety of bioaerosol agents. Controlling bioaerosol exposures is very complicated due to the limited amount of research available and because there are no established regulatory or authoritative exposure limits.
Three cattle operations, two beef and one Dairy, in Utah were investigated to establish exposure profiles of the full-time employees that directly …
Student Absenteeism And The Comparisons Of Two Sampling Procedures For Culturable Bioaerosol Measurement In Classrooms With And Without Upper Room Ultraviolet Germicidal Irradiation Devices, Chunxiao Su, Josephine Lau, Shawn G. Gibbs

Upper room ultraviolet germicidal irradiance (UVGI) has been shown to reduce the concentration of bioaerosols in controlled chambers. However, there is a lack of experimental results on the reduction of bioaerosol concentrations by UVGI devices in actual uncontrolled buildings. This study was carried out in an American elementary school in the Midwest. Two sampling procedures were carried out in six selected classrooms with similar dimensions that were separated into two groups: (1) UVGI exposure group and (2) non-UVGI control group. Two-stage Tisch culturable impactors were utilized to collect airborne culturable bacteria and fungi. Monthly samples were collected during unoccupied period …
