Plastic Pollution



Marine Biology




Dr Dannielle Green is a Lecturer in Ecology and Director of the Applied Ecology Research Group in the School of Life Sciences at Anglia Ruskin University. She researches the impact of human activities on land, rivers, seas and oceans. She has especially studied plastic pollution (ranging from plastics bags to microplastic litter) and, more recently, the damage to plants and nature caused by discarded cigarette butts. Her work has informed policy for the United Nations, the European Union, the UK government and the Australian senate.

Dannielle also examines the impact on seas and oceans from climate change, invasive species and from urbanisation more broadly. She also explores biodiversity, biogeochemistry of marine sediments, and the ecology of the seabed. She studied for her PhD at University College Dublin - where she investigated the ecological impacts of invasive oysters. After this she won research funding from the British Ecological Society and the Irish Research Council and conducted research on climate change and plastic pollution in marine ecosystems. She is passionate about science communication and is a regular guest on BBC radio, The Naked Scientists podcast as well as participating in public outreach events such as Soapbox Science.

How Glitter Could Be Damaging Rivers

Tree Hugger  online


“Microalgae are primary producers and, like duckweed, they are at the bottom of the food web, fueling the ecosystem and any impacts on those could cause follow on effects to the food web,” Dannielle Green, lead author and senior lecturer in biology at Anglia Ruskin University in the U.K., tells Treehugger.

Glitter litter 'could be damaging rivers'

BBC News  online


Dr Dannielle Green, senior lecturer in biology at Anglia Ruskin University, told BBC News: "Glitter is a type of microplastic, it can have the same effects as other microplastics and it shouldn't be released in large quantities into the environment.

'Eco-friendly' glitter particles used in clothes and makeup is just as damaging to freshwater habitats and may also encourage the spread of invasive species

Daily Mail  online


'Many of the microplastics found in our rivers and oceans have taken years to form, as larger pieces of plastic are broken down over time,' said paper author and ecologist Dannielle Green of the Anglia Ruskin University in Cambridge.

Microplastics presence in cultured and wild-caught cuttlefish, Sepia officinalis

Marine Pollution Bulletin

2020 Amongst cephalopods microplastics have been reported only in jumbo squid gut. We investigated microplastics in the digestive system of wild cuttlefish (Sepia officinalis) as they are predators and prey and compared the stomach, caecum/intestine and digestive gland (DG) of wild and cultured animals, exposed to seawater from a comparable source.

Smoked cigarette butt leachate impacts survival and behaviour of freshwater invertebrates

Environmental Pollution

2020 Smoked cigarette filters a. k.a. “butts”, composed of plastic (e.g. cellulose acetate) are one of the world’s most common litter items. In response to concerns about plastic pollution, biodegradable cellulose filters are being promoted as an environmentally safe alternative, however, once smoked, both contain toxins which can leach once discarded.

Biological and Ecological Impacts of Plastic Debris in Aquatic Ecosystems

Springer, Berlin, Heidelberg

2020 Plastic debris is now ubiquitous in aquatic ecosystems worldwide and may impact different biological levels of organisation, with effects ranging from individual organisms to ecosystem functioning. Demonstrating these effects is not always straightforward, and there is uncertainty at every level.

Interactive effects of warming and microplastics on metabolism but not feeding rates of a key freshwater detritivore

Environmental Pollution

2019 Microplastics are an emerging pollutant of high concern, with their prevalence in the environment linked to adverse impacts on aquatic organisms. However, our knowledge of these impacts on freshwater species is rudimentary, and there is almost no research directly testing how these effects can change under ongoing and future climate warming.
