New research by NOC scientists shows the first observed reduction in lead concentrations in the surface waters of the seas around Europe since the phasing out of leaded petrol. Lead has no biological function, and is toxic to humans and marine organisms. The study, published in Geophysical Research Letters, is based on samples of the Celtic Sea taken during a series of research expeditions on board the Royal Research Ship (RRS) Discovery. The results show that there has been a four-fold reduction in the concentration of lead in the surface waters of European shelf seas compared to measurements undertaken two to three decades ago, following the phase-out of leaded petrol in Europe over the same time period.
