Development, Validation, and Application of Methods for High Time-Response Measurement of Gaseous Atmospheric Chlorinated Species
… the fate of chemicals, including ozone, methane, and volatile organic compounds (VOCs). These halogen radicals, in particular atomic chlorine (Cl), can deplete ozone and will react rapidly with VOCs. Reliable, sensitive, and widely available hydrogen chloride (HCl) measurements are important for …

Assessing how South African Development Community Countries' National Adaptation Planning addresses health impacts: A scoping review
The impacts of climate variability and climate change are recognised as key challenges of the 21st century. The African continent has heightened vulnerability to the impacts of a changing climate as it is heavily reliant on agriculture for food and jobs; and experiences high levels of poverty, …

Characterisation of atmospheric single particles in industrial and regional background environments using aerosol time of flight mass spectrometry
… important factor in determining their impact on climate and health. In this study, an aerosol time-of-flight mass spectrometer (ATOFMS) was used to measure the chemical composition of ambient single particles at two contrasting locations – an industrial site in Dunkirk, France and a regional …

Chemical and Physical Studies of Secondary Organic Aerosol Formed from Beta-pinene Photooxidation
… organic aerosols have a significant impact on climate and human health. However, our understanding of the physical and chemical properties of these aerosols is inadequate, thus their climate and health influences are poorly constrained. In this study, we investigated the secondary organic …

Field measurements and atmospheric simulation chamber studies of selected biomass burning marker compounds
… air pollution, which has significant impacts on climate and health. Biomass burning emits both solid particles and gaseous species known as volatile organic compounds (VOCs) which can undergo chemical oxidation reactions in the atmosphere with hydroxyl (OH) and nitrate (NO3) radicals to produce …

Explanatory model of antecedents and outcomes of health and safety climate in the South African construction industry
Workplace injuries and fatalities are a major cause of concern for government and organisations in South Africa. The cost incurred by government as compensation for injuries that occur in the workplace has increased steadily over the past 10 years. This has raised the need for alternative …

Investigating the Valley Fever – Environment Relationship in the Western U.S.
… is a disease caused by the Coccidioides immitis and Coccidioides posadasii fungal species that dwell in the soil but can become airborne and infect a human or mammalian host through their respiratory tract. Disease rates in the western U.S. have significantly increased over the past two decades, …

SPECIATION STUDIES FOR BIOGENIC VOLATILE ORGANIC COMPOUNDS AND SECONDARY ORGANIC AEROSOL GENERATED BY OZONOLYSIS OF VOLATILE ORGANIC COMPOUND MIXTURES
… organic compounds (VOCs) by OH radicals, NOx, and O3. Aerosol can be visualized as suspended solid or liquid particle which is in equilibrium with surrounding gases. The products of SOA formation is a mixture of semi volatile organic compounds and a fraction of the products are condensable …

Phenotypic and microbial influences on dairy heifer fertility and calf gut microbial development
Pregnancy loss and calf death can cost dairy producers more than $230 million annually. While methods involving nutrition, climate, and health management to mitigate pregnancy loss and calf death have been developed, one potential influence that has not been well examined is the reproductive …
