Accumulation versus remobilization of mercury in sediments of a contaminated la...
Ramalhosa, Elsa; Pato, P.; Monterroso, Paulo; Pereira, Eduarda; Vale, Carlos; Duarte, A.C.http://apps.isiknowledge.com/full_record.do?product=UA&search_mode=GeneralSearch&qid=12&SID=V12mKh9k9n8jHN@CK7o&page=1&doc=2&colname=WOS ; This work discusses the extent of sediment mercury retention in the most contaminated sites in the lagoon, and its exportation to the water column as well as transfer to biogenic suspended particles and to sea bass (Dicentrarchus labrax). Therefore,the main question, with i...
Mercury distribution in Douro estuary (Portugal)
Ramalhosa, Elsa; Pereira, Eduarda; Vale, Carlos; Válega, M.; Monterroso, Paulo; Duarte, A.C.Determinations ofdissolved reactive and total dissolved mercury, particulate and sedimentary mercury, dissolved organic carbon (DOC), particulate organic carbon (POC) and suspended particulate matter (SPM) have been made in the estuary ofriver Douro, in northern Portugal. The estuary was stratified by salinity along most ofits length, it had low concentrations of SPM, typically <20 mg dm-3, and concentrations o...
Storage and export of mercury from a contaminated bay (Ria de Aveiro, Portugal)
Ramalhosa, Elsa; Monterroso, Paulo; Abreu, Sizenando; Pereira, Eduarda; Vale, Carlos; Duarte, ArmandoMercury has been determined in water, suspended particulate matter (SPM) and sediments (solid fraction and pore water) collected in a heavily contaminated confined area (Largo do Laranjo) of the Ria de Aveiro. Mercury has been analysed in seabass (Dicentrarchus labrax) captured in several locations of the lagoon. The levels of mercury in water and SPM in the contaminated sampled places fluctuated daily with the...
