Dr Rosalinda Gioia's research focuses on the atmospheric concentrations of POPs and factors controlling their spatial and temporal distribution from source regions (Europe) to remote areas (the Arctic and the open Atlantic Ocean), using active high volume air samplers and passive air samplers (PUF disks and SPMDs). Her major objective is making comparisons between classes of compounds (PCBs, PBDEs, PAHs and selected organochlorine pesticides) in terms of long-range atmospheric transport, sources (primary or secondary) and sinks controlling their concentrations in the atmosphere. Understanding the fate of POPs in the global environment and their air-surface exchange has been and still is the focus of much of her research. Her efforts have been directed towards the remote marine environment and understanding coupled exchange processes between air and water and the role of phytoplankton and particles in removing dissolved POPs from surface water. This is a fascinating and important area raising questions about the role of biological processes in global POPs cycling. She is also working on an air monitoring network funded by the Department of Environment, Food and Rural Affairs (DEFRA).
