Awadhesh Jha, Professor in Genetic Toxicology and Ecotoxicology, is a leading voice in exposing the effects chemicals have on the 环境, 尤其是来自辐射, and in reducing the number of live fish used in toxicity experiments. 他领导的 Environmental and Applied Biology 研究 Group that evaluates risks from natural and man-made hazards in the food chain to ensure global food security.

The impacts of chemicals on the natural world

Awadhesh was one of the first academics to adopt multidisciplinary approach and combine his marine ecotoxicological experience with that of chemists to assess the exposures and effects of radiation and other 环境al stressors on marine organisms, at a time when very few researchers were looking at the human impacts on marine species, especially at 分子水平.  

He has led research that shows how decreasing levels of oxygen in the water could impact fish or rising sea temperatures could accelerate the impacts of radiation in marine invertebrates, how complex chemical compounds could affect the 环境, and how persistent organic pollutants and engineered nanoparticles react with biota once in the 环境.

In collaboration with industrial partner, AstraZeneca, he has pioneered new research techniques such as the ‘虚拟鱼的项目, whereby his team successfully cultured and maintained cells from rainbow trout that now means toxicity tests can take place on manufactured cells, 而不是活鱼.


Is the 核 energy gamble worth it?

Nuclear energy production is ready and available now and emits fewer green-house gases than oil or gas. This makes it an attractive option for decreasing the reliance on fossil fuels in the race to carbon net-zero. 但它会产生放射性废物, causing a headache for governments in how to store and dispose of it.

通过 大型甲板躺椅, a £5 million Horizon 2020 collaborative project funded by the European Commission, Awadhesh is now looking at how the radionuclide waste from 核 设施 can cause harm to the 环境 and those living close to them, and examining how to reduce the release and impact of tritium into the 环境 when ‘fusion’ technology is in operation to secure energy sustainability or when a facility is dismantled. Awadhesh's work has taken him to Chernobyl – the site of the 1986 核 explosion – a number of times, and alongside supervised researchers, has undertaken substantial research into assessing the impact on humans and wildlife through the 树项目. 他的工作也导致了 大学加入了 西南核中心.


“有350多个,000 commercial chemicals in circulation and they will undoubtedly end up in the 环境.”

We are ranked first out of 379 institutions worldwide against the United Nations’ Sustainable Development Goal number 14: life below water.

The award recognises the quality of our marine research and teaching as well as our efforts to reduce the impact of campus activities on the marine 环境. The Times Higher Education 影响 Rankings are the only global performance tables that assess universities against the United Nations’ Sustainable Development Goals (SDGs).


Times Higher Education 影响 Rankings 2021: life below water

The chemicals we are investigating are being developed in many forms; from food additives to the ingredients and by-products of industrial produces and those used in 核 sectors.

But identities of many chemicals remain unknown because of commercial interests and we have no idea about their chemical properties, let alone what impact they will have in the 环境. However, what we do know is there is no universal law to govern them. Providing the evidence to inform such laws is one of the biggest challenges we face.

Our marine and maritime excellence in world-leading research informs policy agendas for the sustainable management of ocean resources. Our work has significantly improved how to forecast extreme coastal events and their impact on communities. We were the first to study the ecological effects of ocean acidification, and now lead the UK agenda for offshore renewable energy. On national and international levels, 365足彩外围网站app影响了关键政策, 保护实践, 应对气候变化, 公众对海事问题的看法, and are defining the pathways toward tangible solutions.

The culture of close collaboration across the city with researchers, 政策制定者, and local businesses has resulted in 普利茅斯’s nomination for the UK’s first National Marine Park – an initiative underpinned by research at the University.
