Interest in understanding the extent of plastic and specifically microplastic pollution has increased on a global scale. Still one large piece overall puzzle currently lacks: how much found its way into deeper areas world's oceans? The deep-sea sediments remains poorly quantified, but this knowledge is imperative for predicting distribution potential impacts pollution. We quantified microplastics from Great Australian Bight using an adapted density separation dye fluorescence technique....
As plastic production increases, so to do the threats from pollution. Microplastics (defined as plastics <5mm) are a subset of marine debris about which we know less than larger items, though they potentially ubiquitous in environment. To quantify distribution and change microplastic densities through time, sampled sediment cores an estuary Tasmania, Australia. We hypothesized that type, abundance microplastics observed would be associated with increasing production, coastal population...
Plastic production is increasing globally and in turn there a rise of plastic waste lost into the coastal marine environment. To combat this issue, an increase policies that target specific types (such as microbeads shopping bags). Given such anthropogenic have environmental impacts, reduce tourism income area result human health issues, identifying effective abatement imperative to reducing litter before it enters ocean. Within Australia, state local governments employ plethora policies,...
Brand names can be used to hold plastic companies accountable for their items found polluting the environment. We data from a 5-year (2018-2022) worldwide (84 countries) program identify brands on in environment through 1576 audit events. that 50% of were unbranded, calling mandated producer reporting. The top five globally Coca-Cola Company (11%), PepsiCo (5%), Nestlé (3%), Danone and Altria (2%), accounting 24% total branded count, 56 accounted more than 50%. There was clear strong log-log...
Abstract Marine debris is a burgeoning global issue with economic, ecological and aesthetic impacts. While there are many studies now addressing this topic, the influence of urbanisation factors such as local population density, stormwater drains roads on distribution coastal litter remains poorly understood. To address knowledge gap, we carried out standardized surveys at 224 transect 67 sites in two estuaries along open coast Tasmania, Australia. We explored relative support for three...
In the age of Anthropocene, ocean has typically been viewed as a sink for pollution. Pollution is varied, ranging from human-made plastics and pharmaceutical compounds, to human-altered abiotic factors, such sediment nutrient runoff. As global population, wealth resource consumption continue grow, so too does amount potential pollution produced. This presents us with grand challenge which requires interdisciplinary knowledge solve. There sufficient data on human health, social, economic,...
There is an increased focus on plastic pollution and the resultant harms in our oceans shores at local, regional, global scales. New technologies are being developed trialed, multilateral agreements coming into play, role of a circular economy increasingly touted as key to help solve crisis. Simultaneously, we witnessing disruption supply chains from COVID-19 pandemic, fuel prices scope scale natural disasters. Individual countries setting national targets developing plans action combat...
Plastic pollution is rapidly increasing, with land-based sources being the major contributors. Understanding factors driving waste movement from land to sea crucial for reducing leakage environment and its subsequent impact. In 2023 we conducted a stratified survey of mismanaged in across six Australian metropolitan regions, covering inland, riverine, coastal habitats, determine national baseline debris environment. We completed 1907 transects, found average density was 0.15 items m-2....
The dialogue on solutions to plastic pollution date has largely focussed targeting commonly found items or areas where large volumes of litter accumulate in the environment. need identify better reduce at global scale been highlighted recent G7 and G20 discussions. Negotiations are underway for a global, legally-binding Plastics Treaty that countries will hopefully agree on, however, local implementation agreement be challenging complex. Cultural norms values likely influence adoption new...
Abstract This paper aims to guide the stakeholder engagement process related plastic pollution research in marine environments. We draw on advice identified during an online workshop (Ocean Plastic Workshop 2022) organized by Early Career Ocean Professionals (ECOPs) from 11 countries, held April 2022. International experts and participants discussed their experiences collaborative development implementation of ocean projects worldwide, guided three main questions: (i) What is role scientists...
Bottled water is one sector of the beverage industry that has recently experienced substantial growth. The littering plastic bottles and carbon emissions produced from bottled production results in harmful effects on environment. To reduce harm litter, government non-government organisations have implemented litter abatement behavioural change strategies targeting consumption subsequent loss to Our study evaluated success these strategies, which a filtered refill station, along Brisbane...
