Abstract Estuaries are sinks of materials and substances which are released directly into them or transported from rivers that drain the basin. It is usual to find high organic matter loads and fine particles in the sediments. We analyzed radionuclide concentrations (210Po, 230Th, 232Th, 234U, 238U, 226Ra, 228Th, 228Ra, 40K) in sediments and three different Read more about Radionuclides transfer into halophytes growing in tidal salt marshes from the Southwest of Spain[…]
