UV sources and plastic composition influence microplastic surface degradation: Implications for plastic weathering studies Open

Stephen D. Burrows, John M. Colwell, Sarah Costanzo, Sarit Kaserzon, Elvis D. Okoffo , et al. · 2024

Microplastic surface properties are dynamic in the environment, as weathering, primarily through photooxidation due to ultraviolet light (UV) exposure, modifies surface chemistry and surface roughness, which can affect the fate, transport …

There's something in the air: A review of sources, prevalence and behaviour of microplastics in the atmosphere Open

Stacey O’Brien, Cassandra Rauert, Francisca Ribeiro, Elvis D. Okoffo, Stephen D. Burrows , et al. · 2023

Environmental science Chemistry Materials science

Literature regarding microplastics in the atmosphere has advanced in recent years. However, studies have been undertaken in isolation with minimal collaboration and exploration of the relationships between air, deposition and dust. This re…

Airborne emissions of microplastic fibres from domestic laundry dryers Open

Stacey O’Brien, Elvis D. Okoffo, Jake O’Brien, Francisca Ribeiro, Xianyu Wang , et al. · 2022

Environmental science Engineering

An emission source of microplastics into the environment is laundering synthetic textiles and clothing. Mechanical drying as a pathway for emitting microplastics, however, is poorly understood. In this study, emissions of microplastic fibr…

Quantification of selected microplastics in Australian urban road dust Open

Stacey O’Brien, Elvis D. Okoffo, Cassandra Raeurt, Jake O’Brien, Francisca Ribeiro , et al. · 2022

Environmental science Geography Geology

Microplastics (1 - 5000 µm) are pervasive in every compartment of our environment. However, little is understood regarding the concentration and size distribution of microplastics in road dust, and how they change in relation to human acti…

Release of plastics to Australian land from biosolids end-use Open

Elvis D. Okoffo, Benjamin J. Tscharke, Jake O Brien, Stacey O’Brien, Francisca Ribeiro , et al. · 2021

Business Environmental science Engineering

Plastics are contaminants of emerging concern that can enter the\nenvironment from multiple sources, including via land application\nof treated sewage sludge (biosolids). Biosolids samples collected\nfrom 82 wastewater treatment plants (WW…

Out of sight but not out of mind: Size fractionation of plastics bioaccumulated by field deployed oysters Open

Francisca Ribeiro, Elvis D. Okoffo, Jake O’Brien, Stacey O’Brien, Jonathan M. Harris , et al. · 2021

Chemistry Biology Engineering

Microplastics contamination has been widely reported in filter feeders yet the < 1 μm size fraction has been largely ignored. In attempt to characterize this sub 1 μm size fraction and better understand the size distribution of microplasti…

Quantitative Analysis of Selected Plastics in High-Commercial-Value Australian Seafood by Pyrolysis Gas Chromatography Mass Spectrometry Open

Francisca Ribeiro, Elvis D. Okoffo, Jake O’Brien, Sarah Fraissinet-Tachet, Stacey O’Brien , et al. · 2020

Chemistry Environmental science Biology

Microplastic contamination of the marine environment is widespread, but the extent to which the marine food web is contaminated is not yet known. The aims of this study were to go beyond visual identification techniques and develop and app…

The Prevalence and Predictors of Dietary Supplement Use in the Australian Population Open

Stacey O’Brien, Eva Malacova, Jill Sherriff, Lucinda J. Black · 2017

Medicine Biology Sociology

Current dietary supplement use in Australia is not well described. We investigated the prevalence and predictors of supplement use in the Australian population (n = 19,257) using data from the 2014–2015 National Health Survey. We reported …
