Jeanette Rotchell, today an Associate Dean for Research and Enterprise at the University of Hull, led the Sullied Sediments project. Specialising in environmental toxicology research, she loves a good detective challenge where poisons are concerned. ”I’m very interested in all things that make you die,” she remarks cheerfully.
Sullied Sediments explored how to manage unwanted chemicals found in the muddy floors of rivers and lakes. Some of these, like phosphate, are well known, whereas very little is known about others, such as the so-called EU Watch List chemicals. ”In this project, we tackled both the usual suspects and the new suspects,” says Rotchell.
While buried in the mud, the chemicals are rather inert. But unfortunately, they can be unlocked from this stable condition if the sediments are disturbed, for example by excavation or floods, and revert to a harmful state. This is set to happen more often in the future due to the growing risk of floods.
