Scientists tend to look at the impact of one chemical on single species in a lab, which doesn&#039;t account for the complexity of the natural world. </p>    <p>&quot;Plants and animals in natural environments may be exposed to hundreds of chemicals. A far more holistic approach to assessing the effects of combinations of chemicals and other factors on ecological communities is needed to protect our natural world.</p>     <p>&quot;Every day the shampoo we wash down the drain, the cleaning products we use and the emissions from our cars have a complex effect on our biodiversity. The ecological impact of this exposure may vary due to the presence of other stressors, for example elevated temperature, and the sensitivity of the plants and animals exposed to the chemicals.&quot;</p>      <p>She added: &quot;Our research will really help to focus scientific effort on the questions that really matter and inform decisions about the type of investigations needed to update environmental policies and regulations.&quot;</p>   <p>The pioneering research is part of a much larger global horizon scanning exercise co-ordinated by the Society for Environmental Toxicology and Chemistry. Similar studies are also being performed in North America, Latin America, Africa, Asia and Australasia.</p>    <p>The international team of scientists identified 22 questions which need to be answered in order to fill the most pressing knowledge gaps. They include questions about which chemicals we should be most concerned about, where the hotspots of key contaminants are around the globe and how we can develop methods to protect biodiversity and ecosystems.</p>     <p>Professor Maltby said: &quot;A lot of chemicals such as pesticides and medicines obviously have a huge benefit for people but it is important to consider the environmental cost too in order to strike a balance.</p>   <p>&quot;By prioritising 22 questions we hope that scientists will be able to identify which chemicals to target first and also the most vulnerable areas.&quot;    </p>  <p>###</p>    <p>Towards Sustainable Environmental Quality: Priority Research Questions for Europe is published in the journal <em>Environmental Toxicology and Chemistry</em>. It is one of six papers in a global horizon scanning study.</p>   <p>The University&#039;s Department of Animal and Plant Sciences is home to one of the biggest communities of whole-organism biologists in the UK. Research in the department, which is fed into learning and teaching for Sheffield students, covers animals, plants, humans, microbes, evolution and ecosystems, in habitats ranging from the polar regions to the tropics. This work aims to shed new light on the fundamental processes that drive biological systems and help solve pressing environmental problems.</p>   <p>To view the full paper please visit: https://setac.onlinelibrary.wiley.com/doi/full/10.1002/etc.4205</p>     <p>Study in the Department of Animal and Plant Sciences</p>     <p>For further information please contact: Amy Huxtable, Media Relations Officer, University of Sheffield, 0114 222 9859</p>    <p><strong>Notes to editors</strong></p>    <p><strong>The University of Sheffield</strong></p>     <p>With almost 29,000 of the brightest students from over 140 countries, learning alongside over 1,200 of the best academics from across the globe, the University of Sheffield is one of the world&#039;s leading universities.</p>    <p>A member of the UK&#039;s prestigious Russell Group of leading research-led institutions, Sheffield offers world-class teaching and research excellence across a wide range of disciplines.</p>      <p>Unified by the power of discovery and understanding, staff and students at the university are committed to finding new ways to transform the world we live in.</p>   <p>Sheffield is the only university to feature in The Sunday Times 100 Best Not-For-Profit Organisations to Work For 2018 and for the last eight years has been ranked in the top five UK universities for Student Satisfaction by Times Higher Education.</p>      <p>Sheffield has six Nobel Prize winners among former staff and students and its alumni go on to hold positions of great responsibility and influence all over the world, making significant contributions in their chosen fields.</p>      <p>Global research partners and clients include Boeing, Rolls-Royce, Unilever, AstraZeneca, Glaxo SmithKline, Siemens and Airbus, as well as many UK and overseas government agencies and charitable foundations.</p>                <p><strong>Media Contact</strong></p>    <p>Amy Huxtable<br/>[email protected]<br/>01-142-229-859<br/> @sheffielduni
