A recent study published in the Marine Pollution Bulletin by Alyssa Rodrigues, Dr David Oliver, Amy McCarron and Dr Richard Quilliam has demonstrated that plastic nurdles on Scottish beaches can harbour bacteria such as E.coli and Vibrio spp., meaning that the ‘plastisphere’ in the ocean has the potential to act as a vector for diseases. Read their paper here, or read coverage of the story in The Guardian, The Scotsman, IFL Science, National Geographic Italia (in Italian), and Le Parisien (in French).
Mairi Gougeon MSP, Minister for Rural Affairs and the Natural Environment, visited the University of Stirling and met with Dr Richard Quilliam to find out more about the £1.85 million research project into how marine plastic can act as a vector for pathogenic organisms. Mairi said: “We are all now well aware that plastic pollution threatens our marine environment, caused by our dependence on plastic and throwaway culture. Little is known of the long-term harm caused by marine plastics, whether to marine species or humans. As such, research like this by the University of Stirling is key to improving our understanding, and enabling the protection of our seas on which we rely for climate regulation, food and so much more.” Read more about the visit here.

In other news, Sarah Buckerfield received one of the SAGES prizes for the best post-graduate publications for 2017/18 for her publication How can improve understanding of faecal indicator dynamics in karst systems under changing climatic, population, and land use stressors. This paper identifies a series of research priorities needed to progress the knowledge base underpinning management of faecal contamination in karst landscapes, which are highly prone to water contamination problems. The review focuses on paddy farming regions, home to a large proportion of the rural population of the Asia-Pacific, and a land-use setting that has received little to no research attention in this field. Read Sarah’s paper here.
Kathleen Stosch and Dr David Oliver both presented research findings at the International Water Association’s 3rd Regional Diffuse Pollution Conference in Chiang Mai, Thailand.

Heather Purshouse has been awarded a grant from the Parkes Foundation to explore whether composting toilets meet the needs of menstruating women and girls in Malawi. Composting toilets are designed to safely collect and convert faeces and urine into compost, and are widely promoted across Africa as a sustainable strategy to improve sanitation and produce low-cost fertiliser. However, it is not clear whether these facilities are able to satisfactorily meet the physical, mental and cultural needs of menstruating women and girls. Certain requirements of composting toilets, e.g. preventing water or rubbish from entering the toilet vault, conflict with need to wash bodies and hands in privacy, clean blood stains on the toilet, and dispose of used menstrual rags with discretion. This project will use in-depth qualitative interviews with women and girls who are long-term users of composting toilets to discuss their behaviours, experiences, beliefs and opinions. These will be compared and contrasted with traditional toilet (pit latrine) users, and developed into suggestions for improving the suitability and comfort of composting toilets for menstruating women and girls.
Excellent progress is being made on the ViPER II project and the integration of the ViPER platform with SCIMAP to develop SCIMAP-FIO, a FIO risk mapping decision support tool (coupling FIO source risks with hydrological connectivity).
