O fitoplancton é de grande importância para os estudos das interações solo-água, como indicadores de modificações químicas e biológicas nos ecossistemas naturais. O objetivo desse estudo foi determinar a composição química total do fitoplâncton nos estuários do rio Pará e Mocajuba (Pará, Brasil). As análises químicas foram realizadas na água superficial, sedimento de fundo (amostra total e fração biodisponível) e no fitoplancton, por espectrometria óptica e de massa com plasma indutivamente acoplado. A composição química elementar do fitoplancton é composta por elevadas concentrações de Ca, P, Mn, Fe, Zn, Al, Ba e Pb. O fitoplancton do estuário do rio Mocajuba é rico em Fe (2.967 a 84.750 µg g-1) e do rio Pará rico em Al (1.216 a 15.389 µg g-1), provavelmente com contribuição antropogênica. O material fitoplanctonico apresentou elevado fator de bioconcentração proveniente tanto da água quanto da fração biodisponível, e reflete a eficiência desses organismos em concentrar metais.

| description |
Phytoplankton is important bioindicator of chemical and biological modifications of natural ecosystems. The objective of this study was to determine the total chemical composition of the phytoplankton of the Pará and Mocajuba estuaries on the eastern coast of the Amazon region in the Brazilian state of Pará. The chemical composition of the surface water, bottom sediments (total sample and bioavailable fraction), and the phytoplankton were determined by inductively coupled plasma optical emission spectrometry. Phytoplankton contained high concentrations of Ca, P, Mn, Fe, Zn, Al, Ba, and Pb. The phytoplankton of the Mocajuba estuary is rich in Fe (2,967-84,750 µg g-1), while those from the Pará is rich in Al (1,216-15,389 µgg-1), probably reflecting divergent anthropogenic inputs. Both samples indicated a high bioconcentration factor derived from both the water and the bioavailable fraction, reflecting the efficiency of these organisms in the concentration of metals. |
