Brad Prezant
Mr. Prezant a public health scientist, epidemiologist, Certified Occupational Hygienist (COH), Certified Industrial Hygienist with sub-specialty certification in Indoor Air Quality (CIH) and indoor air quality specialist (indoor environmental professional, IEP). He has worked during his professional career primarily in consulting.
Mr. Prezant received his training in epidemiology and public health at the School of Public Health and Community Medicine, University of Washington, (in the U.S.), began his professional employment there, and remained affiliated for several decades as an Associate Professor, Department of Occupational and Environmental Health. Mr. Prezant focused on occupational and public health issues including moisture and mould, and indoor air quality in commercial, residential, and industrial environments. He founded and operated for 20 years a consulting company, Prezant Associates, Inc., in Seattle Washington, that was sold in 2007.
More recently, Mr. Prezant worked for Massey University in New Zealand conducting research on occupational health issues. He is currently employed by Prezant Environmental in Melbourne, Victoria, providing consulting services throughout Australasia. His recent focus has been on developing a risk calculator for COVID-19 (2020) and conducting tracer tests for defining ventilation in ACH using SF6 with FTIR detection in public buildings, schools, and child care centres (2021).

This study will provide an overview of the occupational causes of cancer in New Zealand. In addition, it will provide easily accessible, quantitative, and New Zealand-specific data on the extent and industrial distribution of occupational exposure to carcinogens. This will not only provide estimates of the number of workers exposed to carcinogens, but will also help determine the key exposures and key industries for which intervention would result in marked improvements in occupational health. This study will also provide new knowledge on interventions and their effectiveness and the perceptions and behaviours regarding health and safety in key New Zealand industries. The study’s stakeholder engagement will result in a greater industry awareness of the occupational cancer problem and the potential benefits of interventions. Finally, this study will build international research partnerships and will increase the occupational health research capacity in New Zealand.
Bioaerosols occur as airborne particles in a size range of ~0.02–100 µm; thus, different cells, spores, pollen grains, and biological fragments may deposit in all regions of the human airways. Smaller bioaerosols remain airborne for longer periods and travel further distances, which makes it possible for one person in a shared space to expose a large number of individuals to an infectious agent. Microorganisms, plants, and animals are important components of surface waters and soil. Although not particulate in form, plants and animals release gases and vapors, e.g., oxygen, carbon dioxide, methane, and water. Emissions from microorganisms (microbial volatile organic compounds, MVOCs) account for the earthy smell that follows a rain shower or comes from freshly turned garden soil. The distinctive flavors of certain foods and beverages as well as the less pleasant aromas of decay, body odor, and moldy buildings are also volatile microbial metabolites. The complex interactions of MVOCs and bioaerosols with other airborne particles are seldom studied but are likely important for a comprehensive understanding of the effects of biological agents on human health and comfort. While it is impossible to cover this broad topic in great depth in a single chapter, we discuss health effects, dosimetry, and bioaerosol measurement with illustrations and examples from the vast literature on the subject.
