Bioaccumulation of metals and PCBs in Raja clavata

Autor: Regina Tristão da Cunha, Cristina Micaelo, Armindo Rodrigues, Paulo Torres

Publikováno v: Science of The Total Environment. 573:1021-1030

The goal of this study was to assess stable isotopes profiles, metals concentration and PCBs in Raja clavata muscle and liver, according to sex and size, and to elucidate its suitability as a Mid-Atlantic biomonitor. The results reflected bioaccumula

Autor: Cristina Micaelo, Carmen Morales-Caselles, Carlos Vale, Ana Maria da Costa Ferreira, Judit Kalman, T.A. DelValls, Inmaculada Riba

Publikováno v: Chemosphere. 71:1207-1213

Sediment contamination and three bioassays were used to determine the sediment quality four years after an oil spill (Prestige, 2002): the Microtox® test, a 10-day bioassay using the amphipod Ampelisca brevicornis, and a polychaete 10-day toxicity t

Are coastal resources of NW Portugal fingerprinting hydrocarbons released from the Prestige accident?

Autor: Ana Maria Ferreira, Cristina Micaelo, Carlos Vale

Publikováno v: Ciencias Marinas. 29:109-114

Seventy-one samples of mussels, sardine, hake, blue whiting and pouting from the NW Portuguese coast, collected between 18 November 2002 and 6 January 2003, were analyzed for total hydrocarbons, individual n-alkanes and major isoprenoids, pristane an

Evidence for concentration of anthropogenic mercury in salt marsh sediments

Autor: Isabel Caçador, Mónica Válega, Carlos Vale, Eduarda Pereira, Armando C. Duarte, Cristina Micaelo

Publikováno v: Ciencias Marinas. 29:447-456

Sediment cores from two salt marshes, Rosário (Tagus estuary) and Laranjo (Ria de Aveiro), were analyzed for total Hg and Al, and for Fe and Mn extracted with a hydroxylamine-acetic acid solution. Both areas have been contaminated by industrial disc

Screening of priority pesticides in Ulva sp. seaweeds by selective pressurized solvent extraction before gas chromatography with electron capture detector analysis

Autor: Gerhard Sontag, M.I. Pinto, João Paulo Noronha, Carlos Vale, Cristina Micaelo

Publikováno v: Archives of environmental contamination and toxicology. 67(4)

This work reports a fast and reliable analytical method for the screening of priority pesticides (PPs) in Ulva sp. seaweeds by gas chromatography with electron capture detection. Extraction and sample clean-up were performed in one single step by sel
