Phosphorus (P) is a key nutrient for marine organisms. The only long-term removal pathway for P in the marine realm is burial in sediments. Iron (Fe) bound P accounts for a significant proportion of this burial at the global scale. In sediments under

The chemical forms of phosphorus (P) in sediments are routinely measured in studies of P in modern and ancient marine environments. However, samples for such analyses are often exposed to atmospheric oxygen during storage and handling. Recent work su

Every year about 10-14 million m3 of sediments are dredged in the Port of Rotterdam (PoR) as part of harbor maintenance. Approximately 10% of these sediments are stored in a confined disposal facility (CDF) Slufter due to high levels of toxic metals

The abundances and isotope compositions of molybdenum (Mo) and uranium (U) in ancient sediments are promising tracers of the redox state of the past ocean, whose basis lies in the environmentally dependent Mo and U isotope signatures in modern oceani

Phosphate loading alters schwertmannite transformation rates and pathways during microbial reduction
Publikováno v:
Science of The Total Environment. 657:770-780
Acid sulfate systems commonly contain the metastable ferric oxyhydroxysulfate mineral schwertmannite, as well as phosphate (PO3−4) - a nutrient that causes eutrophication when present in excess. However, acid sulfate systems often experience reduci
